Dishwasher Repair Guide - Replace dishwasher drain hose

How to replace a dishwasher's drain hose:

Replacing a drain hose
Disconnect the power source to your dishwasher before you conduct this or any other repair. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.

Before you can replace your dishwasher's drain hose, you have to gain access to the hose. First remove the lower kickplate panel located below the door. This panel can be removed by removing a couple of screws that are located either above or below the panel. On some models, the dishwasher door has to be open to access and remove the screws, but then closed in order to remove the panel.

With the panel removed, locate the drain hose. It is connected to the pump located below the lower spray arm. The drain hose runs from the pump to the sink drain, or to the air gap on top of the sink.

Place a shallow pan below the hose to catch any spills. Disconnect the drain hose form the pump by pinching the wire clamp with pliers and then sliding the clamp up the hose. Remove the hose from the pump.

Reconnect on end of a new hose to the dishwasher's pump assembly and the other end of the new hose to the sink drain.

Replace the clamps, and replace the lower panel. Reconnect the dishwasher's power supply and run the dishwasher to make sure it is functioning proplerly.
