We will discuss here the steps of how to winterize a dishwasher.

Step 1: Turn off the dishwasher

Before you begin the winterizing process, you need to turn off your dishwasher. This can be done by flipping the breaker switch or unplugging the dishwasher from the electrical outlet.

You also need to turn off the water supply to the dishwasher by turning off the valve under the sink or in the basement.

Step 2: Disconnect the water supply

Once the dishwasher is turned off and the water supply is shut off, you need to disconnect the water supply line from the dishwasher.

This is usually located at the back of the dishwasher and can be detached by loosening the screw or clip that holds the line in place.

You should also disconnect the drain hose from the dishwasher and place a bucket under the end to catch any residual water.

Step 3: Drain the dishwasher

Next, you need to drain the dishwasher. This can be done by removing the lower rack and placing a shallow dish on the bottom of the dishwasher to catch any water.

Then, remove the toe panel or access panel from the dishwasher to reveal the pump and motor. Locate the drain hose that runs from the pump to the drain, and disconnect it from the pump. Allow the remaining water to drain into the dish.

Step 4: Drain the pipes

After draining the dishwasher, you need to drain the pipes to prevent freezing. This can be done by opening the hot water tap nearest the dishwasher and letting the water run until it is clear. This will clear out any remaining water in the pipes. Repeat this process with the cold water tap.

Step 5: Seal the pipes

Seal the pipes

Once the pipes have been drained, you need to seal them to prevent drafts. You can use insulation foam or pipe wrap to cover the pipes.

This will keep the pipes warm and prevent freezing. You can also use a draft stopper or door snake to prevent cold air from entering the area around the pipes.

Step 6: Store the dishwasher

Finally, you should store your dishwasher in a dry, protected area such as a garage or basement. Cover the dishwasher with a protective cover or plastic tarp to prevent dust and debris from accumulating on it. This will also help to keep the dishwasher dry and protected from moisture.
