How to fix LG F37

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

  2. Reset at the breaker

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

When to call a technician

If F37 returns with the door area clear, the auto-open mechanism needs service.
