Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG F35

  1. Reset at the breaker

    Turn the dishwasher off, switch the breaker off for about 10 seconds and back on, then run a new cycle.

  2. Book the repair with the code

    If F35 returns, tell LG the exact code when you book. The heat dry heater and sensor sit inside the unit and aren't a homeowner job.

When to call a technician

If F35 returns after a reset, request service to test the heat dry heater and sensor.
