How to Clean a Fill Valve in a Whirlpool Dishwasher
- 1). Disconnect the electrical power going to your dishwasher by turning off the switch in your breaker box that coincides with your dishwasher.
- 2). Tighten the handle on the valves that control the water flowing from the pipes in your wall to your dishwasher. This will shut off the water.
- 3). Unscrew the screws holding the bottom panel of the dishwasher in place and remove the bottom panel. Set this panel aside.
- 4). Place a towel under the fill valve. You will see a brass piece extending down on the left side of the dishwasher. This extension is part of the fill valve. Place a towel under this area to catch any remaining water that may escape the pipes during this process.
- 5). Use an adjustable wrench to disconnect the small water supply line that is connected to the fill valve.
- 6). Grip the brass elbow with the wrench and loosen it. Finish unscrewing this elbow with your fingers and set it aside.
- 7). Unscrew the mounting screw toward the rear left side of the fill valve.
- 8). Slide the fill valve to the right and downward to remove it from the frame of the dishwasher.
- 9). Disconnect the two wires running to the fill valve.
