Step 1 · Turn Off Power and Water
The most critical first step is to completely isolate the dishwasher from its utilities. Go to your home's main electrical panel and locate the circuit breaker that powers the dishwasher. Switch it to the 'OFF' position. If it's not labeled, you may need to turn on the dishwasher and flip breakers until it turns off. Next, look under the kitchen sink for the hot water pipe that leads to the dishwasher. There will be a small shut-off valve on this line. Turn the valve handle clockwise until it stops to shut off the water supply. If there is no dedicated valve, you will have to shut off the main water supply to the entire house.
