KitchenAid Dishwasher Error Code 6-1

The 6-1 code means the dishwasher detected a low or no water condition during the fill cycle. The control board stopped the cycle because the tub did not reach an adequate water level within the expected time. Causes include a closed water supply valve, a clogged fill valve, a stuck overfill switch, a detached drain loop, or an electrical problem in the fill valve circuit.

No, you should not run the dishwasher while the 6-1 code is active. Operating the wash pump and heating element without adequate water can cause those components to overheat and fail. Resolve the underlying fill issue before running another cycle to avoid additional damage.

Repair costs vary depending on the root cause. If the fix is simply opening a shut-off valve or adjusting the dish load, there is no parts cost. Replacing a water inlet fill valve typically runs in the range of $25 to $80 for the part, while professional labor adds $75 to $150 or more depending on your area. An overfill switch is generally a lower-cost component, often in the $15 to $40 range for the part alone.

Start by confirming the water supply shut-off valve under the sink is fully open and the supply hose is not kinked. Next, check your dish loading to make sure no bowls are facing upward and trapping water. If those checks do not resolve the code, the fill valve inlet screen may need cleaning, the overfill switch may need testing, and the drain hose loop should be inspected to confirm it is properly routed and secured.

A reset may temporarily clear the code, but it will return if the underlying cause is not fixed. You can attempt a reset by canceling the cycle or cutting power to the unit at the breaker for a few minutes. If the water supply and fill system are not addressed, the 6-1 fault will reappear at the start of the next fill cycle.
