Error codeF35
ApplianceDishwasher
Which dishwashers show F35
The code belongs to LG dishwashers with Dynamic Heat Dry. When the machine cannot take a reading of the temperature at its Heat Dry components, F35 lights up.
Suspected parts and the advice
LG names two possibilities: the Heat Dry heater and the temperature sensor.
Finding out which one is at fault needs a detailed inspection.
The guide therefore says to request service.
Compare with these codes
A stopped Heat Dry fan motor is covered under F31. Door opening trouble belongs to F37, while HE is the heater error in which the water is not being warmed.
Repair for LG dishwashers in San Francisco
For dishwashers in San Francisco and across the Bay Area, LG dishwasher repair is booked on (415) 223-7887. Give F35, the model number and the fact that the unit has Dynamic Heat Dry.
Model compatibility: LG reuses codes across series and model years, so F35 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F35 means a Dynamic Heat Dry dishwasher cannot read the temperatures of its Heat Dry components.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
