Haier washing machines are sold across many international markets, including India, China, Europe, the United Kingdom, Australia, the Middle East and other regions. Depending on the machine generation and platform, Haier washers may display error codes in several different formats.

Common examples include:

E1, E2, E3, E4, E5, E6, E7, E8, E9

FC, FC0, FC1, FC2

UNB / Unb

Err1, Err2, Err3, Err4, Err5, Err6, Err7, Err8, Err9, Err10, Err13

These codes can indicate problems involving drainage, water filling, door locking, load balance, temperature sensing, heating, motor operation, water-level detection, overflow protection or communication between electronic control boards.

However, there is one extremely important point:

Haier error-code meanings are model and platform dependent. The same code can have a different meaning on another Haier appliance or washing-machine series. Always verify the code against the user/service manual for the exact model before replacing components.

For example, Haier's official top-load troubleshooting information identifies E1 as a drainage problem, E2 as an open-lid condition, E3 as an unbalanced load, E4 as a water-inlet problem, FA as a water-level sensor failure, and FC2 as communication failure between the display and power boards.

Therefore, this article should be used as a diagnostic reference rather than a universal replacement for the model-specific service manual.

Haier E1 Error – Drainage Problem

On several Haier top-loading washing machines, E1 indicates that the machine cannot drain properly or that drainage is taking too long. Haier's official troubleshooting information advises checking the drain hose for blockage and its installation height.

Common symptoms

Water remains inside the tub.
Machine stops before spin.
E1 appears on the display.
Drain pump may run continuously.
Washer may make a humming noise.
Clothes remain soaking wet.

Possible causes

Blocked drain hose
Kinked or crushed hose
Incorrect drain-hose installation
Clogged pump/filter
Foreign object inside drain path
Failed drain pump
Drain-pump wiring problem
Control-board problem

Solution

Disconnect power before inspection.

Check the drain hose for bending, crushing or obstruction. Clean any user-accessible drain filter according to the manual.

If the pump can be heard running but little or no water leaves the washer, inspect for a blockage before assuming the pump itself has failed.

Haier also notes that clogged filters, restricted hoses and pump obstructions are common causes of washing-machine drainage problems.

Haier E2 Error – Lid or Door Problem

On applicable Haier top-load machines, E2 means that the top lid has not been properly closed. Haier advises closing the lid and pressing Start/Pause again.

Possible causes

Lid is open.
Clothing is trapped around the lid.
Lid switch is not being activated.
Lid switch is defective.
Door/lid wiring is loose.
Control board cannot detect the closed state.

Solution

Remove anything preventing the lid from closing and close it firmly.

If E2 remains even though the lid is properly closed, the lid switch, wiring or electronic controller may require testing.

Haier E3 Error – Unbalanced Load

On applicable Haier top-loading machines, E3 indicates that the laundry is distributed unevenly or that the washing machine itself is not level.

Symptoms

Machine refuses to spin.
Drum repeatedly attempts to balance.
Excessive vibration occurs.
E3 appears during spin.

Solution

Pause the cycle and redistribute the clothing.

Avoid washing one heavy item by itself. Towels, blankets, jeans and similar items can collect on one side of the drum.

Check that all four feet are firmly touching the floor and that the appliance is level.

Haier E4 Error – Water Inlet / Filling Problem

On many Haier washing-machine platforms, E4 indicates that the required water level has not been reached within the permitted time.

Haier officially lists common causes as:

Water tap closed
Interrupted water supply
Blocked inlet valve/filter
Water pressure too low

Troubleshooting

Check that the water tap is fully open.

Inspect the inlet hose for:

Kinks
Crushing
Incorrect installation
Blockages

Turn off the water supply before disconnecting the hose.

Inspect and clean the small inlet screen where permitted by the model instructions.

If water pressure is unusually low throughout the building, the washer may simply be unable to fill within its programmed timeout.

If water supply is normal but E4 continues, possible faults include the inlet solenoid valve, pressure sensing system, wiring or control PCB.

Haier E5 Error

E5 is not safe to interpret universally across every Haier washing-machine platform.

Its meaning should be checked against the exact model number.

Do not replace a heater, sensor, motor or PCB solely because an online generic code list associates E5 with that component.

Haier E6 Error

E6 is another platform-dependent diagnostic code.

On certain washer generations, E6/Err6 may be associated with motor operation or speed detection.

Possible technician-level checks may include:

Motor connector
Motor windings
Tachometer/speed feedback
Wiring harness
Drive electronics
Main PCB

Because these tests involve mains-powered circuitry and potentially high-current motor electronics, internal diagnosis should be performed by qualified personnel.

Haier E7 Error – Motor/Drive Fault

On some Haier washer families, E7/Err7 relates to a motor or drive-system malfunction.

Potential causes include:

Motor failure
Motor overheating
Loose motor connector
Damaged wiring harness
Speed feedback failure
Drive/control PCB problem
Drum mechanically jammed

What the user can check

Switch off and unplug the washer.

Check whether the drum rotates normally by hand where the design permits.

Remove excessive laundry and restart after allowing the machine to cool.

If E7 returns, professional diagnosis is recommended.

Haier E8 Error – High Water Level / Overflow

On some Haier platforms, E8 or Err8 indicates that the detected water level has exceeded the permitted protection level.

This is potentially more serious than a simple inlet timeout.

Possible causes include:

Water inlet valve stuck open
Pressure sensor failure
Pressure hose blocked
Pressure hose disconnected
Excessive detergent foam
Wiring fault
Main PCB failure

Important test

If water continues entering the washer even when the appliance is switched off or unplugged, close the water tap immediately.

A mechanically stuck inlet valve can allow water to continue flowing without electrical power.

Do not continue operating a washer that is overfilling.

Haier E9 Error

E9 is model dependent.

On some Haier washer-dryer platforms, Err9 has been associated with the dryer temperature-sensing circuit. Service documentation for some Haier platforms describes Err9 as an open- or short-circuit condition involving the drying temperature sensor.

Possible checks include:

Dryer temperature sensor
Sensor connector
Wiring harness
Electronic control board

Always confirm this interpretation against the model manual.

Haier FA Error – Water-Level Sensor Fault

Haier officially identifies FA on applicable top-load machines as a water-level sensor failure.

The water-level sensor tells the controller how much water is inside the machine.

Possible causes

Failed pressure/water-level sensor
Blocked pressure hose
Split or disconnected pressure hose
Loose electrical connector
Wiring fault
PCB input circuit failure

Because incorrect water-level detection can potentially cause overfilling, FA should not be repeatedly ignored or reset.

Professional service is recommended if basic inspection does not reveal an obvious issue.

Haier FC, FC0, FC1 and FC2 Errors – Communication Failure

These codes deserve special attention.

Haier states that FC, FC0, FC1 and FC2 indicate an internal communication error in applicable washing machines and recommends contacting after-sales service.

Haier also specifically describes FC2 on certain top loaders as a communication failure between the display board and power board.

What does communication failure mean?

Modern washers often contain several electronic modules, such as:

User-interface/display PCB
Main control PCB
Power PCB
Motor inverter/drive board
Sensor circuits

These modules communicate electronically.

If the expected data signal disappears, the machine may stop and display FC-series errors.

Possible causes

Loose wiring connector
Damaged communication harness
Oxidised connector
Moisture contamination
Display-board failure
Power-board failure
Main PCB failure
Voltage/power-supply problem

Basic reset

Switch off the machine and unplug it for several minutes.

Reconnect it and test again.

If the FC error immediately returns, repeated resetting is unlikely to solve an actual communication failure.

PCB diagnosis should normally be left to a trained technician.

Haier UNB / Unb Error – Unbalanced Laundry

UNB or Unb generally indicates that the washer cannot safely complete the spin because the load is unbalanced.

Older Haier documentation describes Unb as a condition in which spinning cannot be completed because of laundry imbalance.

Causes

One large item
Clothes gathered on one side
Overloaded washer
Very small load
Machine not level
Weak suspension components
Excessive water remaining because of drainage problems

Solution

Pause the washer.

Redistribute the clothing evenly.

If washing one large item, add one or two suitable items to improve balance where allowed by the care instructions.

Check that the washer is level and stable.

If UNB occurs during almost every wash regardless of load, inspect the suspension system, shock absorbers, springs and balance sensing system.

Haier Err1 – Door Not Properly Closed

Haier's official troubleshooting information associates Err1 with a door/latch problem.

Recommended basic checks include reopening and firmly closing the door, checking whether clothing is trapped between the door and gasket, and making sure the washer is level.

Causes

Door not completely closed
Clothing trapped in gasket
Damaged latch
Failed door interlock
Loose wiring
Control-board problem

Never bypass a washing-machine door interlock.

The lock is an important safety device preventing access to a moving drum.

Haier Err2 – Drainage Failure

Err2 is one of the better-documented Haier washing-machine error codes.

Haier describes Err2 as a drainage failure.

Official troubleshooting recommends checking:

Drain hose installation height
Drain filter
Drain-hose blockage

On the referenced models, Haier specifies a drain-hose-end installation range of approximately 80–100 cm above floor level. Always use the installation requirement for your exact model.

Detailed troubleshooting

Step 1 – Disconnect power

Never open the pump filter while the washer remains powered.

Step 2 – Prepare for water

If the drum contains water, opening the filter may release a considerable quantity.

Use towels and a shallow container.

Step 3 – Clean the filter

Remove:

Coins
Buttons
Hair
Threads
Lint
Small clothing items
Other foreign objects

Step 4 – Check the drain hose

Make sure it is not:

Kinked
Crushed
Blocked
Installed too high

Step 5 – Inspect the pump

If the filter and hose are clear but the machine still cannot drain, the drain pump or its electrical circuit may require professional testing.

Haier Err3 – Temperature Sensor Fault

On several older Haier front-load platforms, Err3 indicates a wash-temperature sensor or thermistor fault.

Possible causes include:

Failed NTC thermistor
Loose sensor connector
Broken wiring
Short circuit
Open circuit
PCB sensing-circuit failure

Technician diagnosis

A technician can measure the thermistor resistance and compare it with the manufacturer's temperature/resistance specification.

Do not replace the PCB before verifying the sensor and wiring.

Haier Err4 – Heating Error on Applicable Models

Err4 requires careful model identification.

On some older Haier front-load machines, Err4 indicates that the washer has failed to heat correctly or that the heating element circuit has malfunctioned. Documentation for certain Haier models identifies Err4 as a heating-element error or failure to reach the selected temperature within the expected period.

Possible causes include:

Failed heating element
Heater wiring fault
Thermistor problem
Excessive laundry load
Relay/control-board problem

Do not confuse this with E4 on many Haier top-load machines, where E4 is a water-fill error.

This illustrates why the exact displayed format and washer model are critical.

Haier Err5 – Water Level Not Reached

On applicable Haier front-load and washer-dryer models, Err5 means that the machine has failed to reach the expected water-fill level within the permitted time. Haier Appliances' support information similarly identifies Err5 on applicable combination washer/dryers as a failure to sense a full water fill.

Check

Water tap
Water pressure
Inlet hoses
Inlet screens
Solenoid valve
Pressure sensor
Pressure hose
Wiring

If no water enters at all, begin with the external water supply before diagnosing electronics.

Haier Err6 – Motor Speed/Operation Fault

On some older Haier platforms, Err6 relates to the motor or its speed-detection system.

Potential causes include:

Motor connector disconnected
Motor failure
Tachometer failure
Harness problem
Excessive mechanical load
Main controller problem

Internal testing requires electrical knowledge and should generally be performed by a qualified technician.

Haier Err7 – Motor Fault

Err7 is commonly associated with the motor/drive system on applicable models.

Possible symptoms include:

Drum does not rotate.
Washer fills but does not tumble.
Cycle stops during washing.
Machine cannot spin.
Err7 repeatedly returns.

Possible causes include:

Motor overheating
Failed drive motor
Loose motor wiring
Motor speed feedback fault
Drive electronics failure
Mechanical drum restriction

Allow an overheated washer to cool before restarting.

If Err7 returns, service is recommended.

Haier Err8 – Overfill / Water Level Above Protection Limit

Err8 commonly indicates an excessive water-level condition on applicable Haier platforms.

Potential causes include:

Inlet valve stuck open
Pressure sensor problem
Pressure hose blockage
Incorrect pressure reading
Wiring failure
PCB problem

If water continues entering uncontrollably, close the supply tap immediately.

Haier Err9 – Dryer Temperature Sensor Fault

On applicable Haier washer-dryer models, Err9 can indicate a drying temperature sensor open/short-circuit condition.

Possible causes include:

Failed drying thermistor
Loose sensor connector
Broken wire
Short circuit
Display/control PCB problem

This code may not apply to washing-only machines.

Haier Err10 – Model-Specific Error

Err10 should be treated as model/platform specific.

Do not assume a universal meaning.

Record the complete washer model and serial information and consult the appropriate manual or Haier service documentation.

Haier Err13 / E13

Err13/E13 is another code where the machine family is particularly important.

Haier Appliances' support documentation for certain combination washer/dryer models associates E13 with lint buildup and provides a model-specific cleaning procedure.

That does not mean every Haier washer displaying 13 has the same problem.

On a washer-dryer, possible areas requiring attention may include:

Lint accumulation
Airflow path
Drying system
Condensing system
Sensors

Follow the instructions specifically provided for the model.

Why Haier Error Codes Sometimes Appear to Contradict Each Other

This is one of the most important things to understand when troubleshooting Haier appliances.

A search for:

“Haier E4 error”

may produce several completely different explanations.

This happens because Haier manufactures many appliance categories and numerous washing-machine platforms.

Even within washing machines there are:

Top loaders
Front loaders
Washer-dryers
Direct-drive machines
Inverter machines
Older mechanical/electronic platforms
New smart washing machines

For example:

E4 on an applicable Haier top-load washer = water filling problem.

Err4 on some older Haier front-load platforms = heating-related problem.

These are not necessarily contradictory. They are different diagnostic systems.

How to Identify Your Haier Washing Machine Correctly

Before diagnosing an error, locate the appliance rating label.

Record:

Model number
Serial number
Product code if present
Front-load or top-load design
Washer or washer-dryer
Exact error displayed

The difference between:

and

Err4

can be technically important.

Similarly, FC, FC0, FC1 and FC2 may refer to different communication paths depending on the electronics platform.

General Troubleshooting Procedure

Before assuming that an expensive component has failed, follow a logical diagnostic sequence.

1. Record the exact error

Take a photo before switching off the machine.

2. Disconnect power

Unplug the washer before inspecting hoses, filters, connectors or internal components.

3. Check the external water supply

Verify:

Tap open
Adequate pressure
No kinked inlet hose
No frozen supply
No clogged inlet screen

4. Check drainage

Inspect:

Drain hose
Drain filter
Standpipe
Pump path

5. Check the door

Make sure no fabric is trapped between the door and gasket.

6. Check the laundry load

Redistribute an unbalanced load and remove excessive clothing.

7. Perform a power reset

If no water leakage or electrical fault is suspected, switch the machine off and disconnect power for several minutes before restarting.

A reset can clear a temporary controller state but will not repair a failed pump, sensor, valve, motor or PCB.

How to Troubleshoot a Haier Washer That Will Not Drain

Drain errors are among the most common washer problems.

Check in this order:

Drain filter → drain hose → household drain → pump impeller → drain pump → wiring → pressure sensing → PCB

A blocked filter can prevent the pump from moving sufficient water even though the pump motor can be heard.

Haier recommends periodic filter inspection/cleaning on applicable models.

How to Troubleshoot a Haier Washer That Will Not Fill

Check:

Water tap → water pressure → inlet hose → inlet filter → inlet valve → pressure sensor → wiring → PCB

If the washer receives no water, never immediately assume that the control board has failed.

A closed tap or blocked inlet screen can produce almost identical symptoms.

What If the Haier Washer Keeps Filling With Water?

This condition should be taken seriously.

Turn off the water supply.

If water continues entering even after electrical power has been removed, a mechanically stuck inlet valve is a strong possibility.

If filling stops when electrical power is disconnected, the problem may involve:

Pressure sensor
Pressure hose
Wiring
Control PCB

Professional diagnosis is recommended.

What If the Haier Washer Does Not Spin?

Possible causes include:

Unbalanced laundry
Water still inside machine
Drainage failure
Door not locking
Motor fault
Drive-system problem
Speed sensor fault
Control PCB problem

Always solve a drainage error before diagnosing the motor because many washing machines deliberately prevent spinning when water remains inside the tub.

What If the Door Will Not Open?

Do not force it.

The door may remain locked because:

Water remains inside the drum.
The cycle has not completely ended.
Water temperature is too high.
Door interlock has failed.
Controller still detects an unsafe condition.

If water is visible, resolve the drainage problem first.

When Should You Call Haier Service?

Professional service is recommended when:

FC/FC0/FC1/FC2 repeatedly appears.
Motor errors repeatedly return.
Washer is overfilling.
Water is leaking near electrical components.
Burning smell is present.
Circuit breaker trips.
Heater or thermistor requires electrical testing.
Wiring is burnt or damaged.
PCB failure is suspected.
Error returns immediately after basic troubleshooting.

Haier's official troubleshooting guidance also advises contacting customer care when repair is required rather than attempting complex internal repairs.

Safety Warning

A washing machine combines mains electricity, water, heating components and high-speed mechanical movement.

Before cleaning filters or inspecting accessible components:

Disconnect electrical power.
Turn off the water supply where appropriate.
Allow hot water to cool.
Protect the floor from escaping water.

Do not bypass:

Door interlocks
Lid switches
Thermal protection
Ground/earth wiring
Overflow protection

PCB, inverter, motor and heater testing should be performed only by persons familiar with electrical appliance servicing.

25. Where can I get official Haier troubleshooting information?

Use the Haier support site for your country/region and search using the exact washing-machine model number. Haier India maintains dedicated washing-machine troubleshooting resources.

Final Technical Advice

Haier washing-machine error codes are extremely useful diagnostic clues, but they should never be interpreted without considering the exact model, machine type and code format.

A sensible troubleshooting sequence is:

Identify exact model → record exact code → check simple external causes → inspect water supply/drainage → check load and door → reset power → perform model-specific diagnosis → contact service when internal electrical testing is required.

For common top-load Haier machines, codes such as E1, E2, E3, E4, FA and FC2 have clearly documented meanings, while older front-load and washer-dryer platforms use Err-series codes with a different diagnostic structure.

This distinction prevents one of the most common troubleshooting mistakes: replacing a component based solely on a generic internet error-code list that belongs to a different Haier washer platform.
