What F35 means
On LG dishwashers with Dynamic Heat Dry, F35 means the control cannot measure the temperature of the heat dry parts. That points to the heat dry heater or its temperature sensor, the two pieces the control needs in order to dry dishes safely. Without a reading, the control does not run the dry stage the normal way. Codes can differ by model. You may see damp or wet dishes at the end of a cycle, with the code showing on the panel.
Common causes of F35
- Heat dry heater
- Heat dry temperature sensor
- Wiring or connector to the sensor
1. Let the dishwasher finish or cancel the cycle. 2. Open the door and let the tub cool. 3. Do not touch any heater or open any panel. 4. Dry the dishes by hand if you need them. 5. Call us so we can test the heat dry system.
- We test the heater and the sensor separately, since the code does not say which one.
- We check the connection between the sensor and the control.
- We run the dry stage and confirm a normal temperature reading before we finish.
Other Dishwasher codes
Which part is bad with F35?
The code says the heat dry temperatures cannot be measured. That can be the heater or the sensor. We test both, and the price is in writing before we replace anything.
Will the dishwasher still wash?
It may still wash, but the dry stage can be skipped or poor. The code stays on until the reading is back to normal. We would still advise getting it looked at soon, because the code stays until the reading is restored.
Is it safe to run?
We would not keep running it with a heater circuit in question. Stop using it and let us test it first. Stop using it and let us test the heater circuit with the price in writing first.
Still seeing F35?
A technician diagnoses it on site and gives you the price in writing before any work starts.
