Candy washing machines use electronic self-diagnostic systems to detect abnormal conditions involving the door lock, water supply, drainage system, heating circuit, motor, sensors and electronic control modules.

When the controller detects a problem, the washing programme may stop and an E-series error code may appear on the display.

On some Candy machines without a numerical display, the fault can instead be indicated by a repeating sequence of LED flashes. For example, Candy/Hoover documentation explains that two flashes followed by a pause can represent Error 2.

Important: Candy has manufactured many washing-machine and washer-dryer platforms over the years. The precise interpretation of E06–E22 in particular can vary according to model, motor technology, PCB generation and whether the appliance is a washer or washer-dryer. Therefore, always confirm the code against the manual for the exact model before replacing components. Candy provides an official model/product-code manual search facility.

The codes after E05 are especially model-dependent, so technicians should treat this table as a diagnostic starting point rather than a substitute for the model-specific service documentation.

Candy E01 Error – Door Lock or Door Interlock Fault

Meaning

E01 commonly indicates that the electronic controller cannot confirm that the washing-machine door has been securely locked.

The washer normally refuses to fill or rotate the drum until the door-lock feedback circuit confirms a safe locked condition.

Possible causes

• Door not completely closed
• Clothing trapped between door and seal
• Damaged door handle
• Broken door catch
• Faulty door interlock
• Loose connector at door lock
• Damaged wiring harness
• PCB door-lock circuit failure

Troubleshooting

Switch the machine off and unplug it.

Open the door and inspect the latch area. Check for clothing or foreign objects preventing complete closure.

Close the door firmly and restart the machine.

If E01 returns, the door interlock and its electrical connections should be inspected.

A technician can test whether the PCB is supplying the appropriate voltage to the lock and whether the lock's feedback contact changes state correctly.

Candy E02 Error – Washing Machine Cannot Fill With Water

Meaning

E02 is one of the most common Candy washing-machine errors and normally means that the appliance cannot obtain the required amount of water within the permitted time.

Candy/Hoover service documentation specifically identifies Error 2 as a condition where the machine cannot load water and recommends checking the water tap, inlet hose and drain installation.

Possible causes

• Water tap closed
• Low mains water pressure
• Kinked inlet hose
• Blocked inlet filter
• Faulty inlet solenoid valve
• Incorrect drain-hose installation
• Pressure-sensing problem
• Damaged wiring
• PCB fault

Solution

Check that the water tap is fully open.

Inspect the inlet hose for:

• Kinks
• Crushing
• Blockages
• Incorrect routing

Disconnect the inlet hose after turning off the water supply and inspect the small mesh filter at the valve connection.

If adequate water pressure reaches the machine but it still fails to fill, the inlet solenoid valve may require electrical testing.

Candy E03 Error – Drainage Fault

Meaning

E03 normally means that the washing machine cannot drain its water within the expected period.

Typical symptoms include:

• Water remaining in drum
• Machine stopping before spin
• Wet clothes
• Drain pump running continuously
• E03 appearing near the end of the programme

Most common causes

• Blocked pump filter
• Coin or foreign object inside pump
• Blocked drain hose
• Kinked drain hose
• Blocked household waste connection
• Failed drain pump
• Wiring problem
• Pressure sensor incorrectly detecting water

Candy's own drainage guidance identifies a blocked filter, obstructed drain hose and objects trapped in the drainage pump as common causes of a machine failing to drain.

Solution

Disconnect the washer from electricity.

Drain the machine carefully before opening the pump filter.

Place towels and a shallow container underneath because considerable water may escape.

Remove and clean the filter.

Inspect the pump impeller for:

• Coins
• Buttons
• Hair clips
• Threads
• Fabric
• Other foreign objects

Check the drain hose and household waste pipe.

If everything is clear but the pump does not operate, electrical testing of the pump and wiring is required.

Candy E04 Error – Excess Water or Overflow Condition

E04 usually relates to excessive water level or an abnormal pressure/overflow condition.

Possible causes include:

• Inlet valve stuck open
• Excessive detergent foam
• Blocked pressure chamber
• Damaged pressure hose
• Faulty pressure sensor
• Incorrect water-level information reaching PCB

If water continues entering the drum even after the washer is switched off, immediately close the water tap.

A mechanically stuck inlet valve can allow water to enter even without electrical power.

Excessive detergent can also create foam that interferes with level detection.

Candy E05 Error – NTC Temperature Sensor Fault

E05 commonly indicates a problem with the NTC thermistor, which measures wash-water temperature.

Possible causes include:

• Open-circuit NTC
• Short-circuit NTC
• Loose NTC connector
• Broken wiring
• Corroded terminals
• Control-board sensor circuit fault

The NTC is commonly positioned in or near the heating-element assembly.

A technician can measure the thermistor resistance with a multimeter and verify that its resistance changes predictably as temperature changes.

Do not automatically replace the heating element simply because E05 appears. The NTC and its wiring should be tested first.

Candy E06 Error – Electronic or Model-Specific Fault

E06 is one of the Candy codes whose meaning can vary considerably between platforms.

Depending on the machine, it may relate to:

• Electronic controller configuration
• EEPROM/control-board problem
• Motor/control issue
• Unbalanced-load detection on certain platforms

Start with a power reset and then retry the appliance with a normal balanced load.

If E06 appears immediately after switching on, regardless of load, electronic diagnostics may be required.

Candy E07 Error – Door or Motor Control Fault

E07 can have different meanings across Candy generations.

Common areas associated with E07 include:

• Door-lock circuitry
• Motor unable to rotate
• Motor-control circuit
• Wiring between motor and PCB

Check whether the drum rotates freely by hand with the machine disconnected.

A mechanically jammed drum must be investigated before repeatedly attempting to operate the washer.

Technician-level diagnosis may involve checking:

• Motor windings
• Carbon brushes where fitted
• Tachometer
• Wiring harness
• PCB motor-control circuit

Candy E08 Error – Motor Speed/Tachometer Fault

E08 commonly indicates that the controller is receiving incorrect or missing motor-speed information.

The washing machine may:

• Refuse to spin
• Rotate erratically
• Accelerate unexpectedly
• Stop during wash
• Display E08 during spin

Possible causes include:

• Faulty tachometer/tacho generator
• Loose tacho connection
• Damaged motor wiring
• Worn carbon brushes on applicable motors
• Motor fault
• Control-board fault

Older machines using universal/collector motors may have replaceable carbon brushes.

Newer inverter or induction-motor systems require different diagnostic procedures.

Candy E09 Error – Motor Triac or Drive-Control Fault

E09 is commonly associated with failure of the electronic device controlling motor power.

The triac is located on the electronic control PCB on applicable designs.

Possible symptoms include:

• Drum not rotating
• Washer filling but not washing
• No spin
• Immediate programme failure

Check the motor and wiring before condemning the PCB because a motor or wiring fault can sometimes damage the electronic drive circuit.

PCB-level repair should only be performed by appropriately trained personnel.

Candy E10 Error – Model-Specific Sensor or Communication Fault

E10 varies significantly across Candy product generations.

Depending on the appliance it may relate to:

• Drum-position sensor
• Motorised programme selector on older machines
• Communication fault
• Water-level/pressure sensing on some designs

Because of these variations, do not purchase an E10 replacement component based only on a generic internet error-code list.

Identify the full model and product code and consult the corresponding technical documentation.

Candy E11 Error – Washer-Dryer Heating/Sensor Fault

On many Candy washer-dryer platforms, E11 relates to the drying system.

Possible causes include:

• Open-circuit dryer heater
• Dryer temperature sensor problem
• Broken heater wiring
• Loose connector
• Control-module fault

If washing works normally but drying fails, this provides an important diagnostic clue.

Because dryer heaters operate from mains voltage and at high temperature, internal testing should be performed only with appropriate electrical knowledge.

Candy E12 Error – Communication or Washer-Dryer Fault

E12 is commonly associated with either an electronic communication problem or washer-dryer circuitry depending on the platform.

Possible causes include:

• Communication failure between PCB modules
• Damaged wiring harness
• Loose display-board connector
• Moisture/corrosion
• Dryer circuit problem on certain machines
• Main PCB failure

Disconnect the machine from power for several minutes and restart it.

If E12 immediately returns, internal diagnostics are required.

Candy E13 Error – Electronic Communication Fault

E13 is frequently associated with an electronic communication failure.

Potential areas include:

• Main PCB
• User-interface/display PCB
• Wiring between modules
• Loose connectors
• Damaged harness
• Electronic module failure

Before replacing a PCB, inspect all connectors and wiring carefully.

Replacing a control board without identifying the original cause can result in unnecessary expense.

Candy E14 Error – Control Module or Wiring Fault

E14 on applicable Candy machines can indicate a problem involving the main control module or associated wiring.

Recommended checks include:

1. Disconnect appliance from power.
2. Inspect visible wiring and connectors.
3. Look for water ingress.
4. Look for burnt PCB areas.
5. Check connectors for overheating.
6. Verify continuity of relevant wiring.

PCB replacement may require programming or configuration for the exact appliance.

Candy E15 Error – Washer-Dryer Heating/Control Fault

E15 is primarily encountered on certain washer-dryer platforms.

Possible causes can include:

• Drying heater fault
• Heater relay problem
• Wiring failure
• Temperature protection device
• Control-board problem

If washing functions correctly but the drying programme fails, concentrate diagnosis on the dryer circuitry.

Candy E16 Error – Heater, Insulation or Inverter-Related Fault

The interpretation of E16 depends strongly on the model.

Possible areas include:

• Wash heating element
• Heater insulation leakage
• Wiring
• Electronic power module
• Inverter circuitry on applicable machines

A heating element can appear electrically continuous but still leak current to earth.

Professional diagnosis may therefore require both resistance and insulation testing.

Candy E17 Error – Motor Tachometer or Inverter Fault

E17 commonly points toward motor-speed feedback or motor-drive problems on applicable models.

Potential causes include:

• Tacho sensor failure
• Loose tacho connector
• Damaged motor harness
• Motor fault
• Inverter module problem
• PCB fault

Symptoms may include failure to spin, erratic drum movement or programme interruption.

Candy E18 Error – Electronic Control Fault

E18 is generally treated as an electronic/control-system fault on applicable Candy platforms.

Potential causes include:

• Main PCB failure
• Communication failure
• Corrupted controller information
• Power-supply instability
• Wiring fault

Before replacing electronics, technicians should verify mains supply quality and inspect the machine for damaged or loose wiring.

Candy E20 Error – Drain/Pressure or Platform-Specific Fault

E20 is another model-dependent code.

On applicable platforms it may be associated with:

• Drainage
• Water-level sensing
• Pressure system
• Electronic control

Start with the basic hydraulic checks:

• Pump filter
• Drain hose
• Drain pump
• Pressure chamber
• Pressure hose

If these are normal, obtain the technical information for the exact model before replacing components.

Candy E21 Error – Motor Drive/Current Fault

On machines using applicable electronic motor-control systems, E21 may indicate abnormal motor current or a drive-system fault.

Possible causes include:

• Motor winding problem
• Motor mechanically overloaded
• Damaged wiring
• Inverter fault
• Power PCB fault
• Drum mechanically restricted

Check whether the drum rotates smoothly by hand after disconnecting the machine.

An unusually stiff drum may indicate a mechanical problem rather than an electronic failure.

Candy E22 Error – Motor/Inverter Drive Fault

E22 is commonly associated with the electronic motor drive on applicable newer platforms.

Possible causes include:

• Inverter module
• Motor
• Motor wiring
• Current-sensing circuit
• Power/control PCB

These systems generally require professional diagnosis because replacing the motor without testing the inverter—or vice versa—can be expensive and ineffective.

How to Reset a Candy Washing Machine Error

A reset can clear a temporary electronic condition, but it cannot repair a failed component.

A basic reset procedure is:

1. Turn the programme selector to OFF.
2. Switch off the appliance.
3. Unplug it from the mains.
4. Wait approximately 2–5 minutes.
5. Reconnect power.
6. Select a short programme.
7. Start the machine.

If the same error returns, investigate the underlying problem rather than repeatedly resetting the appliance.

Candy Washing Machine Flashing Lights Instead of an Error Code

Some Candy washing machines without a full digital display communicate errors using flashing LEDs.

The basic principle is:

Number of flashes → pause → same number of flashes repeated

For example:

2 flashes → pause → 2 flashes → pause

can indicate Error 2 on applicable machines. This flash-code approach is documented in Candy/Hoover troubleshooting material.

Record the number of flashes carefully before switching off the appliance.

Troubleshooting a Candy Washer That Will Not Drain

Drainage faults are among the easiest problems to investigate safely.

Check:

1. Pump filter
2. Drain hose
3. Household drain
4. Pump impeller
5. Drain-pump operation

Candy recommends disconnecting the appliance electrically before accessing and cleaning the filter. The company also notes that coins, buttons, safety pins and similar objects can obstruct the pump turbine.

Troubleshooting a Candy Washer That Will Not Fill

Check:

• Water tap
• Water pressure
• Inlet hose
• Mesh filter
• Inlet valve
• Drain-hose height

A machine that starts filling and immediately loses the water may have an incorrectly installed drain hose causing siphoning.

Troubleshooting a Candy Washer That Will Not Spin

A failure to spin does not automatically mean the motor has failed.

Check first for:

• Water remaining in drum
• Blocked pump
• Unbalanced load
• Excessive foam
• Drive belt problem
• Worn motor brushes on applicable machines
• Motor-speed sensor fault

Many washing machines will deliberately prevent high-speed spinning if the controller believes water remains inside the drum.

Excessive Detergent Can Cause Washing Machine Problems

More detergent does not necessarily produce cleaner clothes.

Candy warns that excessive detergent can create too much foam, leave residue and contribute to washing problems.

Use detergent according to:

• Laundry quantity
• Water hardness
• Detergent concentration
• Soil level
• Programme type

HE/high-efficiency machines are particularly sensitive to excessive foaming.

Preventing Candy Washing Machine Errors

Preventive maintenance can reduce many common faults.

Candy recommends checking hoses periodically, cleaning the detergent dispenser and maintaining the pump filter. Its maintenance guidance also warns against overloading the machine.

Useful maintenance practices include:

Clean the drain filter

Periodically remove:

• Coins
• Hair
• Threads
• Buttons
• Fabric
• Other debris

Inspect inlet and drain hoses

Look for:

• Cracks
• Bulges
• Kinks
• Leaks
• Loose connections

Keep the detergent drawer clean

Detergent and fabric-softener residue can accumulate and encourage mould growth.

Avoid overloading

Overloading places additional stress on:

• Motor
• Bearings
• Suspension
• Drum
• Drive system

Check pockets

Coins and other objects can enter the drainage system and damage the pump.

Advanced Technician Diagnostic Sequence

When repairing a Candy washer, a systematic approach is more reliable than replacing components based solely on the error number.

Step 1 – Record the fault

Record:

• Exact error code
• Programme selected
• Stage where failure occurs
• Whether water entered
• Whether water drained
• Whether drum rotated
• Whether heater operated

Step 2 – Identify exact model

Record the complete model/product identification.

Candy specifically advises having the appliance serial number available when contacting technical support.

Step 3 – Perform visual inspection

Look for:

• Burnt connectors
• Water leaks
• Loose wires
• Broken hoses
• Damaged door lock
• Foreign objects

Step 4 – Check hydraulic system

Test:

• Water supply
• Inlet valve
• Pressure system
• Drain pump
• Drain hose

Step 5 – Check electrical loads

Depending on the error, test:

• Heater
• NTC
• Pump
• Motor
• Door interlock
• Solenoid valves

Step 6 – Check wiring

Continuity testing should be performed between the affected component and controller.

A perfectly good component can appear faulty to the PCB when its wiring harness is broken.

Step 7 – Diagnose electronics last

Only consider PCB, inverter or display-module replacement after sensors, loads, connectors and wiring have been checked.

Electrical Safety Warning

Washing machines combine mains electricity, water, high-current heating elements and moving mechanical components.

Always disconnect the appliance from mains electricity before removing covers, accessing the pump, disconnecting wiring or performing resistance tests.

Do not perform live-voltage measurements unless you are trained and equipped to work safely on mains-powered appliances.

If there is:

• Burning smell
• Smoke
• Electrical arcing
• Repeated circuit-breaker/RCD tripping
• Water leaking near electrical components
• Melted wiring
• Burnt PCB

stop using the appliance and arrange professional service.

Candy provides technical-support and repair options and recommends trained assistance for significant faults.

Frequently Asked Questions (FAQ)

9. Are E10–E22 codes the same on every Candy washer?

No. These codes can vary substantially between product families, washer-dryers, older collector-motor machines and newer electronically controlled/inverter models.

10. Why does my Candy washer flash instead of showing an error number?

Machines without numerical displays may communicate errors through repeating LED-flash sequences. Count the flashes between pauses.

11. Can I reset a Candy washing machine?

You can try switching the machine off, disconnecting it from power for several minutes and restarting it. A reset may clear a temporary controller problem but will not repair a failed component.

12. Why won't my Candy washer spin?

Possible causes include retained water, blocked drainage, an unbalanced load, excessive detergent foam, motor problems or motor-speed sensor faults.

13. Why does my Candy washing machine keep showing E03 after cleaning the filter?

Check the drain hose, household drain, pump impeller and drain-pump operation. The pump itself may have failed electrically or mechanically.

14. Can excessive detergent cause an error?

Yes. Excessive detergent can produce large amounts of foam and interfere with normal washing, draining and spinning. Candy advises using the correct detergent quantity.

15. Should I replace the PCB when an electronic error appears?

Not immediately. Check wiring, connectors, sensors and associated components first. PCB replacement should generally be the result of diagnosis rather than guesswork.

16. Can a blocked filter stop a Candy washing machine from spinning?

Yes. If a blocked filter prevents drainage, the control system may prevent high-speed spin because it still detects water inside the drum.

17. Where is the drain filter located?

On many front-loading Candy machines the filter is accessible through the lower front area of the appliance. Exact position varies by model, so consult the manual before opening anything.

18. How do I find the correct manual for my Candy washer?

Use Candy's official manual search and enter/select the appliance model or product code.

19. Should I keep using a washing machine that repeatedly trips the RCD?

No. Disconnect the appliance and have it inspected. Earth leakage from a heater, motor, wiring or another electrical component can present a safety risk.

20. When should I call a technician?

Professional diagnosis is recommended when the problem involves the PCB, inverter, motor electronics, persistent communication errors, electrical leakage, burnt wiring, repeated breaker tripping or a fault that remains after basic filter/hose/supply checks.

Final Technical Note

Candy error codes are extremely useful diagnostic clues, but they should not be interpreted as automatic instructions to replace a particular component.

For example:

E03 does not automatically mean "replace drain pump."

A blocked filter or drain hose can produce the same symptom.

Similarly:

E01 does not automatically mean "replace door lock."

The problem could be the latch, wiring, connector or PCB.

The best repair procedure is therefore:

Read error → identify exact model → observe symptoms → inspect simple causes → test components → test wiring → diagnose electronic controller.

Because Candy's product range spans numerous generations and washing-machine/washer-dryer platforms, confirm model-specific E06–E22 definitions using the correct Candy manual or service information before ordering parts. Candy's official support site provides manuals and technical-assistance routes for this purpose.
