LG Washer displaying an tE error
Hi All, Greetings from Sri Lanka.!!!
I'm a newbie for this forum joined here to seek your good advice.
My Washing Machine "LG FC1408S3E"
Initially, it displayed an error "tE" which was deemed to be a thermistor error related to heating.
A local repair guy thought it was a door error and messed up with the door switch which lead me to replace the door switch.
However, After replacing the door switch the tE error was disappeared and the washer was back to normal for a month.
Now again I'm seeing this error "tE" Could you guys could kindly advise me on how I could get this problem fixed?
Appreciate your support. I have attached a video and an error diagnosed by the Application.
Thank you and have a great day!!

LG FC1408S3E showing tE temperature-sensing error
- The problem
- LG washing machine FC1408S3E intermittently displayed fault code tE. The owner said the machine previously returned to normal for about a month after a door switch was replaced, but the tE error later came back.
- Likely cause
- Most strongly supported diagnosis is a fault in the temperature sensing circuit. The accepted reply says this could be the thermistor, a connection fault in the thermistor circuit, wiring/connectors, or possibly the PCB. The exact failed part was not confirmed.
- What fixed it
- Recommended action was to check all connections to the thermistor/temperature-sensing circuit first and, if no connection fault is found, replace the thermistor. The owner said they would contact local LG service. No completed repair was confirmed in the discussion.
- Checks to try
- Fault code tE reported
- Advice to check all connections to the thermistor
- Consider wiring/connector fault between sensor and PCB
- Parts or tools mentioned
- door switch
- thermistor

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello there. Unfortunately error codes are not 100% reliable, but at the end of the day we have to do trust what they say until it is proven to be incorrect, which is rare but it can happen. "A defect in the function which detects the temperature inside the product" could well be a thermistor but it could also be something else such as a connection fault somewhere in the thermistor circuit or even potentially a fault inside the PCB. However, with this error code the sensible thing would be to check all of the connections to the thermistor and if nothing is found replace the thermistor.
Only then can you have eliminated the main suspect indicated by the error code.

Thank you so much for your advice, I shall connect with LG local guys here.
The tE code points to the temperature sensing circuit. A failed thermistor is one possibility, but a damaged connector or wiring fault between the sensor and PCB can produce the same code. I put the common causes and troubleshooting sequence together here: [link removed]
