LG Dishwasher F37 Error Code

Auto-open door not working. Here is what it means and how to clear it, easiest fix first.

F37
May need a pro

The Auto Open Door feature, which pops the door open at the end of drying, is not working. Something blocking the door or a fault in the opening mechanism can cause it.

Models with Auto Open Door only.

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 F37

  1. Clear the door area

    Make sure nothing in front of the door, such as a towel, rug or cabinet hardware, stops it from opening.

  2. Reset the power

    Turn the dishwasher off, then switch off its circuit breaker for about 10 seconds and switch it back on. Power the unit up and start a fresh cycle to see whether the code returns.

When to call a technician

If the code returns with the door area clear, the auto-open mechanism needs service.
