If none of that fixed it

If the code comes back after the reset, KitchenAid says to schedule service rather than to keep going.

Before you check anything

Disconnect the power first. Unplug the machine at the socket, or switch off its circuit at the consumer unit if it is hard-wired. Do this before opening any panel, reaching into a pump filter, or moving the appliance.
Turn off the water before disconnecting a hose, and have a towel and a shallow tray ready — a drain hose holds water even when the drum looks empty.
Gas, mains wiring and sealed refrigeration are for a qualified professional — in many countries that is a legal requirement, not advice. If you smell gas, do not touch any switch: leave, and call your gas emergency number from outside.
Stop if you smell burning, see scorched wiring, or find water near an electrical connection. None of those is a code to look up.

The checks on this page are the manufacturer’s own, rewritten and sourced, and they are reference information rather than a repair instruction for your particular machine. Model, age and installation all change what is safe to do. You are the one standing in front of it — if a step looks wrong for the machine you have, trust that and call a technician.
