Samsung Washing Machine Error Codes

Samsung washing machine error codes are becoming something which more and more consumers are finding themselves searching for online, as Samsung continues to increase the number of units sold within the UK.

If you’ve lost the manual which came with your Samsung washing machine it can be very hard to find a list of all the correct error codes, so we’ve listed them below (please read our important notice at the end of this informational article).

Error CodeCauseSolution
1E, E7Water Level Sensor IssuePlease check the pressure hose system for any blockages, splits, or deterioration. If no damage is found, and the connection is ok, we recommend replacing the pressure sensor.
3E, 3E1, 3E2, 3E3, 3E4, EA, EBMotor DefectCould be an open/short circuit (please check wind resistence), a PCB fault, or a loose connector.
3E1Motor OverloadEnsure there isn’t too much laundry in the appliance, the hall sensor terminal isn’t connected, or a possible PCB fault.
3E2Motor Driving ErrorThe motor driving error from the PBA is weak, unstable relay operation. We recommend replacing the Motor PCB.
3E3Quiet-Drive Motor ErrorFaulty motor hall sensor, faulty PCB connection, or the Quiet Drive motor cover is out of place.
3E4Quiet-Drive Motor DefectThe PCB Housing terminal is not connected, there’s a PCB fault, or the Quiet-Motor drive is faulty.
4E, E1Water Supply Error (only occurs after 10 mins when the pressure sensor is not detecting the unit filling with water)Check the water supply is turned on and has adequate water pressure (Samsung recommends minimum of 0.5bar, and a maximum of 8bar), check for any kinks in the hoses, check inlet filters inside end of Water Valve, check water valve coil resistance, should be 4~5kΩ, check hose from the drum to the sensor. If this is split or cracked it MUST be replaced.
4E1, 4EDWater Temperature IssueCheck to ensure the waster hose is connected to a cold supply. It must NOT be connected to a hot supply.
4E2Water Temperature ErrorThe water is too hot for the selected wash.
5E, E2Water Drain Error (only occurs after 10 mins when water is not draining from the appliance)Check the drain pump filter for any blockages (for e.g. coins, hair clips, lint,etc.), check the drain hose and connection for any blockages or kinks.
6EWater Heater Not FunctioningCheck the heater resistance which should be around ~27Ω.
8EOver Current ErrorSwitch the appliance off at the mains and wait 30 seconds. Switch the appliance on and try again, if the appliance has an inverter motor check windings are not open circuit- causes juddering.
8E1MEMS Sensor ErrorCheck the connections to the MEMS sensor which is mounted on top of the tub. All they’re all secure then replace the sensor.
9E1, 9E2, PH1, PloPower ErrorCheck the supply voltage, check for loose power connectors or any with contact defects, check for defective noise filter and fuse.
AE, 13ESignal Communication Error (between the Main PCB and Sub PCB’s)Check all the connectors on the Main PCB and Sub PCB’s.
bEMotor TRIAC Short ErrorSwich off the power and then reconnect and try again. If the error persists then replace the PCB.
bE1, 12EPower Button FaultPower button held in for more than 13 seconds.
bE2, 14EControl Button FaultAny button (other than the power button) held in for more than 30 seconds.
bE3, 18ESwitch ErrorThere is a relay fault.
CE, E8Cooling Error (temperature of water has not dropped below 55°C in 30 minutes after the washer cooling operation)Check if water supply is connected to hot and if so change to cold only feed, check that the hot/cold water supply is not switched over, if the first two are OK then check the heater temperature sensor.
dE, EdDoor Open Error (door not closed correctly/properly)Door Open Error (door not closed correctly/properly).
dE1Door Lock Switch ErrorCheck that the door is closed, check the switch for any damage and if so please replace.
dE2On/Off Switch ErrorExcessive heat build up in the coil due to button being operated continuously
FEFan Error (Dryer or Air Refresh fan fault)Check start condenser/capacitor and fan motor connections, check to see if the fan is hammed, if no other fault then replace replace the start condenser/capacitor.
H1Incorrect Water Temperature/Water Temperature rises quicklyCheck the temperature sensor, check the pressure switch and hose.
HEAbnormal water temperatureThe temperature sensor has detected temperature over 100°C.
HE1, E5Water Heater Error (this occurs if the water temperature has not reached 50°C in 20 minutes or does not rise more than 2°C)Check the heater resistance which should be ~27Ω.
HE2Dryer Heater Error (occurs if the dryer heater circuit is open circuit)Check heater TCOs. One is resettable. if it needs to be reset; check fan for correct operation, check condenser water valve operation, check condenser for blockages.
HE3Steam Function FaultCheck steam function and TCOs.
HOTAppliance Too Hot (occurs if dryer is turned off early)This is not a fault - the appliance fan will continue to run until the appliance is cool enough for the washing to be removed. The door will unlock when it is safe.
LE, LE1, E9, 11EWater Leak (low water level detected during cycle)Check that the level of the drain hose is not lower than the base of the Samsung washing machine.
OE, E3Overflow Error (too much water/foam has entered into the appliance)Too much washing power/liquid may have been added. Turn the power off to the appliance, wait 30 seconds, and then turn on again. The drain pump should kick into action to drain the appliance. Also check the pressure system for any debris/foam.
OFOverflow Abnormal (water has reached the overflow level)Check for any water valves which have stuck in the open position, check for debris/foam in the pressure system.
SudExcess Foam DetectedThis is normal operation. The appliance will normally cure this condition on it’s own however if it doesn’t then run either an “Eco drum clean” or a 90°C cotton cycle with no detergent and no washing inside. If the problem persists then please check the pressure system and sump for any debris.
t1, t2, tStAppliance In Test ModeSwitch the appliance off at the mains and wait 30 seconds. Then, switch it back on and try again.
tE, ECTemperature Sensor Abnormal IssueSwitch off the power and reconnect and try again. Check all the temperature sensors for relative continuity.
tE1Water Heater Temp Sensor DefectiveCheck the connections to the sensor and PCB, check resistance which should be ~12.8kΩ
tE2Fan Housing Duct Sensor DefectiveCheck the connections to the sensor and PCB, check resistance which should be ~12.8kΩ
tE3Condenser Duct Sensor DefectiveCheck the connections to the sensor and PCB, check resistance which should be ~12.8kΩ
UCExcessuve Fluctuation In The Supply Voltage (voltage has fluctuated outside 176-286vAC)Check that the supply voltage is within specifications, reset the power supply to clear the error. If the error cannot be reset then please replace the main PCB.
UE, E4Unbalanced Error (the washing load in the drum is unbalanced i.e. clothes may have got trapped inside a large towel and resting on one side of the drum)This could be normal operation where the washing machine is stopping the spin for safety reasons. Please distribute washing more evenly. Check the weights and balancers for condition, check the shock absorbers for condition, check the springs for condition.



This list of Samsung washing machine error codes or fault codes and their solutions might not cover every single appliance. Also, not all of the recommended solutions should be attempted by the consumer.

While some of the basic fault fixes can be done at home, this piece is for informational purposes only. Please don’t attempt any repairs at home unless you’re qualified and know what you’re doing. The risks aren’t worth it.

If your Samsung washing machine is faulty, book a repair with Glotech Repairs. All of our engineers are Samsung trained and have lots of washing machine repair experience.

My Sumsung eco 8km displays the code SE

and refuses to move on.
Yet it has drawn in the softener

What do I do?


Monday, June 17, 2019 at 10:02 am

The first thing to do is make sure the soap drawer is cleaned out. If there is the error and it did take the softener then there is a problem with is sensing the softener has gone.

My washing machine says 6n and also blinks 24. What does this mean?

Monday, July 15, 2019 at 6:14 pm

There is no error code for this, some more details explaining how the numbers got to be there might reveal the issue, could be a service menu, but if it is disconnected from the mains for 30 seconds that should reset the PCB.
Sounds like it could be some strange pcb issue if it is not service menu related.

Red thermostat symbol appears and a clicking sound

Thursday, August 29, 2019 at 5:03 pm

I am not sure what you mean by thermostat symbol, the clicking might be the door trying to lock but there should be an error code.

Make sure the door has closed and is shut properly.

My eco bubble stops spinning about 10 minutes into any program but will rinse n spin.

Monday, September 30, 2019 at 8:33 am

When you say ‘spinning’ do you mean ‘drum turning’?
Machines don’t normally spin 10 minutes into a wash. Also does the program stop and is there an error code?

M/c starts up washing cycle then after about 10 minutes it stops with error code UC this has happened about 8-9 times. The m/c is just over a year old.

Wednesday, April 21, 2021 at 12:46 pm

Hi, my machine displays 4c but and it does not wash at all, it’s accompanied by a sound

Thursday, April 22, 2021 at 9:02 am

Morning, My Samsung watching machine is giving me a 4c error.. what does it mean?

Thursday, April 22, 2021 at 2:34 pm

Good afternoon,

The 4c error code indicates that your washing machine has detected an issue with the water supply. This could mean that your washing machine is not able to generate a supply of water due to a blocked or kinked water supply hose. If you would like an engineer to come and diagnose the issue then please give us a call on 01727 896 789.

Kind regards,
