Common KitchenAid error codes and issues
KitchenAid dishwashers show two-number codes (like 3-1 or 4-3) where the first digit narrows down the system and the second identifies the specific fault. Here's what we see most often.
A water supply problem. Check that the supply valve is fully open, then check the inlet valve screen for clogs.
The Optical Water Indicator (OWI) sensor has failed. This sensor measures water clarity and can also cause abnormally long cycle times when it's dirty rather than fully failed.
A wash motor problem — check for blockages first, but a failed motor usually needs replacement.
Often the OWI sensor extending the cycle because it's reading cloudy water — sometimes just needs cleaning rather than replacement.
This pattern usually points to a main control board failure rather than several unrelated component failures.
KitchenAid's kitchen suite shares similar control board architecture — see our oven repair and range repair pages for appliance-specific detail.

KitchenAid repair FAQs
Often it's just a dirty OWI (Optical Water Indicator) sensor extending the cycle while it waits for clearer water. Cleaning it sometimes resolves the issue without needing a replacement part.
The first digit points to the general system (like water supply or the wash motor), and the second identifies the specific fault within it.
Parts can run a bit higher given the brand's premium positioning, but we'll always quote clearly before any work begins so there's no surprise.
Our focus is on installed kitchen and laundry appliances — refrigerators, dishwashers, ranges, and similar. For countertop mixers, a small-appliance specialist or the manufacturer's service center is usually the better route.
Our technicians handle premium finishes carefully during control board or latch work, which sometimes requires careful disassembly of the door panel.
