In this guide, you will find step-by-step instructions for how to remove the old drain pump and then reinstall the new pump. When replacing a part, always make sure you check that it is the manufacturer’s recommended part that you are using.

Preparations

  1. Unplug the power cord at the wall.
  2. Turn the water supply off to the dishwasher. You can do this by turning the water line off at the tap underneath the sink. You’ll then need to disconnect the water line and drain hose so you can move the dishwasher.
  3. Empty the dishwasher if it is full of water.
  4. Remove the dish racks and then remove any screws that are connecting the dishwasher to the kitchen cabinet.
  5. Pull the dishwasher out from its cabinet so you can work on it.

Remove the Old Drain Pump

  1. Depending on your model of GE dishwasher, remove the panels so you can access the components at the bottom of the dishwasher unit. Some models of GE dishwashers are known as “built-in” dishwashers and don’t have side panels. If you’re working on a GE built-in model, you’ll be able to access the drain pump without removing any panels.
  2. Lay a towel down onto the floor to absorb any leaking water.
  3. Place the dishwasher on its side onto the towel.
  4. Locate the drain pump at the bottom of the dishwasher.
  5. Unplug the wires that are connected to the water drain pump terminals (you can use a small flathead screwdriver to help you pop them off). Once unplugged, move the wires out the way.
  6. Use a nut driver to loosen up the clamp that secures the drain pump to the sump. Once the clamp is loose, slide it down the sump a little bit so it’s out of the way.
  7. Use a quarter-inch nut driver to loosen up the clamp that holds the drain hose in place on the drain pump. Once you’ve loosened it, pull the hose off the pump and move it out of the way.
  8. Use the nut driver to remove the two screws that secure the drain pump to the frame.
  9. You can now remove the old drain pump by pulling it out of the sump. You may have to “jiggle” it around a little bit to pull it out.

Install the New Drain Pump

  1. Now that you’ve successfully removed the old drain pump, it’s now time to install the new pump. Take your new drain pump and line it up in the correct position on the sump.
  2. Push it down into place and then make sure the screw holes on the frame and the drain pump are lined up.
  3. Use the quarter-inch nut driver to put the screws back into place.
  4. Reattach the drain hose onto the new drain pump. You can do this by pushing the hose onto the attachment and then tightening the clamp with your quarter-inch nut driver. Make sure that it is on tightly to avoid any leaks occurring.
  5. Reattach the clamp that holds the drain pump onto the sump. Tighten the clamp with your nut driver.
  6. Reattach the wires back into the drain pump terminals.
  7. Lift the dishwasher to an upright position, and remove the towel that you put down earlier.
  8. Reattach the dishwasher panels if applicable.

Restart the Dishwasher

  1. Now that you’ve successfully reinstalled the new drain pump, you can put the dishwasher back into place and secure it with the screws into the kitchen cabinet (if applicable).
  2. Reattach the dishwasher’s water pipes/hoses, and turn the water back on at the water tap.
  3. Plug the dishwasher back in at the wall, and turn the power back on.
  4. Run the dishwasher through a cycle so you can check for any leaks and see if the new drain pump is working correctly. If the cycle runs correctly, the dishwasher is now fixed up and ready to load up with dishes!
