If you open your dishwasher at the end of the cycle and notice standing water in the bottom, you may need a new pump. The pump is not only responsible for sending clean water to the unit to wash your dishes, but it is also responsible for draining the dirty water as well. You can replace the pump yourself with just a few tools. This guide demonstrates the steps you'll need to take.
Step 1: Collect Your Supplies
Find the dishwasher's model number and give it to the associate at the home improvement store so that they can provide you with the correct pump. Then gather these tools and supplies:
- Phillips and flathead screwdrivers
- voltage tester
Step 2: Turn the Power Off
Locate the circuit breaker to the dishwasher and turn it off. If your dishwasher is not hardwired, simply unplug it from the outlet.
Step 3: Gain Access to the Pump
Remove the lower basket from the dishwasher and set it aside.
Check to see which type of screw the lower washer arm is connected with and use the appropriate screwdriver to remove it.
Close the main door and remove the panel below the door by removing the screws holding it in place. Some panels are held in place with flat screws, while others are held in place with Phillips screws. Simply look at the screws and use the screwdriver that matches.
Step 4: Test the Wires
If your dishwasher is hardwired, touch the voltage tester to all the wires you see to ensure no electricity is flowing to the unit. If the wires are still live, you'll hear the tester chirp or beep and see it light up. If this happens, go back to the circuit breaker box, and locate the correct breaker to turn off.
Note: If you cannot locate the correct breaker, call in an electrician who is professionally trained in dishwasher repair.
Step 5: Remove the Hose
Once you are sure there is no electricity flowing to the unit, lay your towel down under the outlet hose. Remove the hose by squeezing the arms of the clamp with the pliers and sliding it down the hose. Then pull the hose off the pump.
Step 6: Disconnect the Wires
Disconnect all the wires connecting the pump to the motor by removing the wire nuts and untwisting the wires.
Step 7: Remove the Pump
Locate the tabs holding the pump on the motor. Unsnap or turn them, depending on the type of tabs your unit has.
Open the main door and reach inside the bottom of the dishwasher to pull the pump straight out.
Step 8: Install the New Pump
Reverse these steps to install your new pump, ensuring that you connect the correct wires together. Use your flashlight to help you see the colors of the wires.
Plan to spend about an hour or so completing this project, once you have procured the pump and other supplies. Ask your appliance repairperson for help should you run into any problems completing these steps.Share
