Modern TCL washing machines use electronic control systems to continuously monitor water supply, drainage, door locking, motor operation, temperature, water level, drum balance and other functions.

When the control system detects an abnormal condition, the washing machine may stop or modify the wash cycle and display an error or status code such as E1, E2, E3, E4, E10, CL or UNB.

Understanding the displayed code can help determine whether the problem is something simple—such as a closed water tap, blocked drain filter or unbalanced load—or whether professional service is required.

Important: TCL Error Codes Are Model-Dependent

There is no single universal TCL washing-machine error-code table that applies to every TCL washer worldwide.

TCL sells different front-load, top-load and fully automatic washing-machine platforms in different countries. The meaning of a code can therefore vary according to:

• Exact model number
• Front-load or top-load design
• Control-board/platform generation
• Motor/inverter design
• Country or market
• Firmware/control configuration

For example, official TCL documentation for some front-loading models defines E1 as slow water filling, E2 as slow drainage, E3 as a door-lock issue, E4 as overflow, E5 as a motor issue, E6 as a heater issue, E7 as a temperature-sensor fault and E10 as an inverter failure. TCL itself warns that different models can have different fault displays.

Therefore, always verify the code against the user manual or service information for the exact model before replacing a component.

You can use TCL's support system to search for documentation by model number.

Important: Codes in the table marked platform-dependent should not be interpreted as a guaranteed component failure without checking the exact TCL model.

TCL Washing Machine E1 Error

Meaning

On documented TCL front-load platforms, E1 means that the washer is taking too long to fill with water.

Possible Causes

• Water tap closed or only partially open
• Low household water pressure
• Kinked inlet hose
• Blocked inlet hose
• Dirty inlet-valve filter screen
• Faulty water inlet valve
• Water-level sensing problem
• Wiring or control problem

Solution

1. Make sure the water tap is completely open.
2. Verify that water is available at the tap.
3. Check whether household water pressure is unusually low.
4. Inspect the inlet hose for bending, crushing or blockage.
5. Turn off the water supply and clean the inlet filter screen if accessible according to the manual.
6. Restart the washer.

If E1 continues despite adequate water supply and an unrestricted inlet hose, the inlet valve, water-level sensing circuit, wiring or electronic controller may require professional diagnosis.

TCL Washing Machine E2 Error

Meaning

On documented TCL models, E2 indicates that water is draining too slowly.

Possible Causes

• Blocked pump filter
• Coins, lint, buttons or debris in the drain system
• Kinked drain hose
• Blocked drain hose
• Incorrect drain-hose installation
• Drain pump obstruction
• Failed drain pump
• Wiring/control problem

Solution

First switch the machine off.

If your model provides a user-accessible pump filter, inspect and clean it according to the manufacturer's instructions. Be prepared for residual water to escape.

Check the drain hose for:

• Kinks
• Crushing
• Blockages
• Incorrect positioning

Restart the washer after correcting the problem.

If you can hear the pump running but water does not drain, there may be an obstruction. If the pump does not operate at all, professional diagnosis may be required.

TCL Washing Machine E3 Error

Meaning

E3 commonly indicates a door-lock or door-closing problem on TCL front-load washers.

TCL specifically advises checking whether the door is properly closed and whether clothing is trapped between the door and gasket.

Possible Causes

• Door not completely closed
• Clothing trapped in the door
• Door catch misaligned
• Door-lock mechanism defective
• Door-lock wiring problem
• Control-board issue

Solution

1. Stop the machine.
2. Open the door.
3. Check the door seal/gasket.
4. Remove any trapped clothing.
5. Close the door firmly.
6. Restart the program.

Do not repeatedly slam the door.

If E3 returns even though the door closes correctly, the door interlock or associated electrical circuit should be inspected.

TCL Washing Machine E4 Error

Meaning

On documented TCL platforms, E4 indicates an overflow or excessive water-level condition.

This should be treated more seriously than a normal filling problem.

Possible Causes

• Inlet valve not closing
• Water-level sensor problem
• Pressure hose blocked/disconnected
• Excessive detergent/foam
• Control-board problem
• Water continuing to enter when it should stop

What to Do

Allow the machine to perform its automatic drainage if it is already doing so.

If water continues entering unexpectedly:

1. Stop the washer.
2. Turn off the water supply.
3. Disconnect power when safe.
4. Arrange professional inspection.

Do not continue operating a washer that repeatedly overfills.

TCL Washing Machine E5 Error

Meaning

On the TCL platforms documented in the manufacturer's manual, E5 indicates an electrical motor issue.

Possible Causes

Depending on the model, technicians may need to investigate:

• Motor failure
• Motor wiring
• Motor connector
• Hall/tachometer feedback
• Motor controller
• Inverter electronics
• Main PCB

Solution

A basic power reset may be attempted, but persistent E5 errors should normally be diagnosed by a qualified technician.

Avoid repeatedly attempting high-speed spin cycles when the motor is failing to operate normally.

TCL Washing Machine E6 Error

Meaning

On documented TCL models, E6 indicates a heater issue.

Possible Causes

• Failed heating element
• Heater wiring problem
• Connector failure
• Temperature-control problem
• Relay/control-board fault

Solution

Disconnect the washer and arrange service if E6 repeatedly returns.

Heating circuits operate at mains voltage, so internal testing should only be carried out by a competent technician.

TCL Washing Machine E7 Error

Meaning

On documented TCL platforms, E7 indicates a temperature-sensor fault.

The sensor is commonly an NTC-type temperature sensor.

Possible Causes

• Failed temperature sensor
• Loose sensor connector
• Broken wiring
• Incorrect sensor resistance
• Control-board fault

Solution

Try restarting the machine once.

If E7 returns, the temperature sensor and its wiring should be tested by a technician.

TCL Washing Machine E8 Error

E8 should be treated as a model-dependent code.

Unlike E1 through E7, it is not listed in the same way in every TCL error table. Some third-party multibrand references associate E8 on particular TCL-derived platforms with an electronic, hardware/software or inverter-related mismatch, but this should not be assumed for every TCL washer.

Recommended Action

1. Record the complete model number.
2. Power the washer off.
3. Disconnect power for several minutes.
4. Restart it.
5. If E8 immediately returns, locate the model-specific manual/service information.

Do not replace the inverter or main PCB solely because the display shows E8 without confirming its meaning for that model.

TCL Washing Machine E10 Error

Meaning

Official TCL documentation for several front-loading models identifies E10 as an inverter failure.

The inverter controls operation of the washing-machine motor on inverter-driven models.

Possible Causes

• Inverter-board fault
• Motor problem
• Loose motor connector
• Damaged wiring harness
• Communication issue
• Main-board/inverter communication problem

Solution

Turn the washer off and disconnect it from power for several minutes.

Restart the machine once.

If E10 returns, professional diagnosis is recommended because troubleshooting may require electrical measurements of the inverter, motor and control circuitry.

TCL Washing Machine E11 Error

E11 is platform-dependent and must be checked against the exact TCL model.

Do not automatically interpret E11 using error-code information from another washing-machine manufacturer.

If E11 appears:

1. Record the model number.
2. Note at what stage the error occurs—fill, wash, drain or spin.
3. Restart the washer once.
4. Check the model's official manual.
5. Contact TCL support if the code is not documented for the user.

The point at which E11 occurs can provide useful diagnostic information to a service technician.

TCL Washing Machine E12 Error

E12 is also model/platform dependent.

A technician may use the accompanying symptom—such as failure to spin, heat, fill or communicate—to narrow the diagnosis, but the code alone should not be used to order replacement components unless model-specific service documentation confirms it.

If E12 repeatedly appears, record:

• Model number
• Serial number
• Selected wash program
• Approximate time before the fault occurs
• Whether water entered
• Whether the drum rotated
• Whether the machine drained

This information can substantially improve service diagnosis.

TCL Washing Machine E21 Error

E21 appears on some TCL washer platforms, but its interpretation should be verified by model.

Published model-specific TCL code databases show E21 among codes used by certain TCL washer models, demonstrating why model identification is important.

On platforms where E21 relates to drainage, useful preliminary checks include:

• Drain filter
• Drain hose
• Drain installation
• Pump obstruction
• Remaining water in drum

However, do not assume E21 universally means a drain-pump failure on every TCL machine.

TCL Washing Machine E30 Error

E30 should be treated as a model-specific diagnostic code.

If E30 appears:

• Switch off the washer.
• Wait several minutes.
• Restart it once.
• Observe whether the error occurs immediately or after the cycle starts.
• Check whether the door locks normally.
• Check whether water enters.
• Record the exact model number.

If the error persists, consult model-specific TCL documentation or service support rather than replacing parts based on a generic Internet error-code list.

TCL Washing Machine E33 Error

E33 is another code whose meaning can vary between electronic platforms.

Possible diagnostic categories on modern washers can include water-level sensing, pressure monitoring, electronics or communication systems, but the exact meaning must be confirmed for the TCL model concerned.

If E33 is persistent, professional diagnosis is recommended.

TCL Washing Machine E50 Error

E50 should also be considered platform-dependent.

On electronically controlled washers, higher-numbered error families may relate to motor-control, inverter or electronic systems, but this cannot safely be generalized to every TCL washer.

Recommended Action

Perform only basic checks:

• Switch off the washer.
• Disconnect power for several minutes.
• Check whether the drum is mechanically obstructed.
• Make sure the machine is not severely overloaded.
• Restart once.

If E50 returns, arrange model-specific diagnosis.

TCL Washing Machine E64 Error

E64 is not part of the standard E1–E10 table documented for the TCL front-load models cited above.

Therefore, do not assume a universal E64 definition.

Some online sources associate E64 with electronic/control-board problems on certain appliance platforms, but such information should not override the manual for the exact TCL washer.

Persistent E64 should therefore be treated as a service-level diagnostic condition until its model-specific definition is confirmed.

TCL Washing Machine CL Display

In many washing machines, CL is an indication rather than a hardware failure and commonly means that Child Lock or Control Lock is enabled.

When Child Lock is active, some or most buttons may not respond.

How to Remove CL

The button combination varies by model.

Look for:

• A lock symbol
• Child Lock marking
• Two buttons connected by a bracket/lock icon
• A button marked Child Lock

On many appliances, the relevant button or button combination must be held for several seconds.

Do not rely on a universal key combination. Check the control panel or manual for your exact TCL model.

TCL Washing Machine UNB Error

UNB generally indicates an unbalanced laundry load on platforms that use this display.

The washer detects that the clothes are distributed unevenly around the drum and may reduce or stop the spin speed to prevent excessive vibration.

Common Causes

• One heavy item being washed alone
• Towels accumulated on one side
• Bedsheets tangled together
• Too few clothes
• Washer overloaded
• Washer not level
• Unstable flooring

Solution

Pause the washer safely and redistribute the clothes evenly.

For one large wet item, adding suitable additional laundry may sometimes improve balance, provided the washer's rated capacity is not exceeded.

Also check that:

• All feet contact the floor
• The machine is level
• Locking nuts on adjustable feet are secure
• Shipping/transit bolts were removed during installation where applicable

Do not repeatedly operate a washer that violently shakes during spin.

How to Reset a TCL Washing Machine After an Error

A basic power reset can clear temporary electronic conditions, although it cannot repair a genuine mechanical or electrical fault.

A general procedure is:

1. Switch the washer off.
2. Disconnect it from mains power.
3. Wait several minutes.
4. Reconnect power.
5. Turn the machine on.
6. Select a short appropriate cycle.
7. Check whether the code returns.

If the same code immediately reappears, repeated resets are unlikely to solve the underlying problem.

Error Appears During Filling

If the error occurs shortly after pressing Start, investigate the water-supply system first.

Check:

• Water tap
• Water pressure
• Inlet hose
• Inlet filter
• Inlet valve

This is particularly relevant to E1 on TCL platforms where E1 represents slow filling.

Error Appears During Draining

If the washer completes washing but stops with water remaining in the drum, inspect:

• Pump filter
• Drain hose
• Household drain
• Drain-pump operation

E2 is specifically documented as slow drainage on several TCL front-load platforms.

Error Appears When Pressing Start

Check whether the door is completely closed.

Remove clothing caught between the glass/door and rubber gasket.

A persistent E3 after confirming proper door closure may indicate a defective door interlock or related circuit. TCL's support documentation specifically recommends checking the door and trapped clothing for E3.

Error Appears During Spin

If an error occurs mainly during high-speed spinning, check:

• Laundry balance
• Overloading
• Drum movement
• Excessive vibration
• Washer levelling
• Motor operation

If UNB is displayed, redistribute the load before assuming that the washer has an electronic failure.

When Should You Call a Technician?

Professional service is recommended when:

• The washer repeatedly trips the electrical supply.
• There is a burning smell.
• Water is leaking from inside the appliance.
• The drum will not rotate.
• The machine continuously overfills.
• E4 repeatedly returns.
• E5 motor errors persist.
• E6 heating errors persist.
• E7 temperature-sensor errors persist.
• E10 inverter errors persist.
• A high-level electronic code repeatedly returns.
• The machine makes grinding or electrical arcing sounds.
• An error returns immediately after every reset.

Disconnect the machine and close the water supply if continued operation could cause flooding or electrical damage.

Information to Collect Before Contacting TCL Service

Before requesting service, note:

1. Exact model number

Do not report only "TCL 8 kg washing machine."

2. Full error code

For example, E1 and E10 are completely different codes.

3. When the error occurs

For example:

• Immediately after Start
• During water filling
• During washing
• During heating
• Before draining
• During spinning

4. Whether water remains inside the drum

This is particularly useful for drainage diagnosis.

5. Whether the drum rotates

This can help diagnose motor/inverter faults.

6. Whether the problem occurs on every program

A problem affecting only certain cycles can provide additional diagnostic information.

TCL provides model-specific support, manuals and repair resources through its support channels.

Frequently Asked Questions (FAQ)

1. What does E1 mean on a TCL washing machine?

On several officially documented TCL front-load platforms, E1 means that the washer is taking too long to fill. Check the water tap, pressure and inlet hose.

3. What does TCL E3 mean?

E3 indicates a door-lock/door-closing problem on documented TCL front loaders. Close the door properly and make sure no clothing is trapped in the gasket.

4. Is TCL E4 dangerous?

E4 represents an overflow condition on documented TCL platforms. If water continues entering the washer unexpectedly, turn off the water supply and arrange service.

5. What does TCL E5 mean?

Official documentation for some TCL front-load platforms defines E5 as an electrical motor issue. Professional diagnosis is recommended if it persists.

6. What does TCL E6 mean?

On documented TCL models, E6 indicates a heater issue.

7. What does TCL E7 mean?

E7 indicates a temperature-sensor fault on documented TCL front-load platforms.

8. What does TCL E8 mean?

E8 is platform-dependent. Check the manual for the exact washer before interpreting or replacing components.

9. What does TCL E10 mean?

Official TCL manuals for several front-load models identify E10 as an inverter failure.

10. Does E21 always mean a blocked drain?

No. Error-code definitions vary by TCL model. If your model defines E21 as a drainage-related error, inspect the filter, hose and pump, but verify the model-specific documentation first.

11. What does CL mean on my TCL washing machine?

CL commonly indicates that Child Lock or Control Lock is enabled rather than a component failure. The method of disabling it varies by model.

12. Why does my TCL washer show UNB?

UNB generally indicates that the laundry is not evenly balanced for spinning. Redistribute the clothes and ensure the washer is level.

13. Why does my TCL washing machine keep stopping before spin?

Possible reasons include an unbalanced load, water remaining because of a drainage problem, door-lock issues or motor/inverter problems.

14. Can I reset a TCL washing machine by unplugging it?

Disconnecting power for several minutes can reset temporary electronic conditions. It will not repair a defective pump, motor, sensor, heater, inverter or control board.

15. Why does the error disappear after restarting the washer?

Temporary power fluctuations, sensor readings or unusual cycle conditions can sometimes trigger a one-time error. If the code repeatedly returns, investigate the underlying cause.

16. Can low water pressure cause an error?

Yes. Low pressure can cause excessive filling time and trigger E1 on TCL models where E1 represents slow filling.

17. Can a blocked filter cause an error?

Yes. A blocked drain-pump filter can prevent the machine from draining within the expected time.

18. Can too much detergent cause washer problems?

Yes. Excessive detergent can create heavy foaming, interfere with water-level detection and cause poor rinsing or drainage behaviour. Always use detergent suitable for the washer and follow the recommended dosage.

19. Should I replace the PCB if I see E50 or E64?

No. Never replace an expensive PCB based only on a generic Internet code list. First confirm what the code means for the exact model and have the associated wiring, sensors, motor/inverter and other components properly diagnosed.

20. Where can I find the correct TCL error codes for my washer?

Check the user manual supplied with the machine or search TCL's support resources using the exact model number.

Important Technical Note

TCL's own documentation specifically states that fault displays can differ between models. This is extremely important when troubleshooting washing machines because codes from one platform should not automatically be applied to another.

For this reason, this guide intentionally distinguishes between codes confirmed in official TCL documentation and codes that require model-specific verification.

Never purchase a motor, pump, inverter board, sensor, door lock or PCB solely from an error-code interpretation found online.

Safety Disclaimer

This article is provided for educational and general troubleshooting purposes only.

Error codes, diagnostic procedures and component configurations can vary according to the exact TCL washing-machine model, manufacturing platform, country and production revision.

Before performing repairs:

• Switch off and unplug the washing machine.
• Turn off the water supply where necessary.
• Do not open electrical or electronic sections unless properly trained.
• Never work on a powered appliance.
• Do not bypass door locks, safety switches or protective devices.
• Refer to the official manual for the exact model.

For persistent motor, heater, inverter, control-board, wiring, overflow or electrical faults, contact TCL or a qualified appliance technician.
