Remove the Old Drain Pump

  1. Turn the power to the dishwasher off. You can simply unplug it at the wall.
  2. If the dishwasher is full of water, empty it by using a small container and a sponge until it’s completely empty. If you don’t empty the water, it will leak out the bottom when you remove the drain pump.
  3. Pull the dishwasher out from the wall so you can work on it. You may have to disconnect the water if the hose isn’t long enough for you to be able to move the dishwasher out.
  4. You can now start taking the dishwasher apart so you can access the drain pump. Start by removing the top panel – there are usually two screws at the rear, which you need to remove. Once removed, set the panel aside out of the way. It’s a good idea to place the screws next to each component so you know which ones go back into each component.
  5. Remove the side panels of the dishwasher by unscrewing the screws – there should be two in the front, and some models have two in the back to remove as well. Once removed, set the panels aside out of the way.
  6. Remove the front part of the door by unscrewing it – be careful not to let the door panel fall onto the floor while you are unscrewing it. Once removed, set it aside out of the way.
  7. Remove the kick strip on the bottom of the dishwasher (it’s the panel at the bottom of the dishwasher underneath the door). On some models, it is attached with two screws, and on others, it clips into place. This will give you access to the cover plate. Once you’ve removed the kick strip, place it with the other parts.
  8. Remove the cover plate by unscrewing the screws that attach it to the dishwasher frame. You can then unclip it by gently pulling it up and then out. Once this panel is removed, you’ll have access to the drain pump.
  9. Remove the water detection sensor by unplugging the wires from it.
  10. Unclip the drain pump by turning it clockwise – this will release it from its housing.
  11. Remove the electric plugs from the drain pump unit – you might have to release the lock on them to detach them. And that’s it. You have successfully removed the old drain pump!

Install the New Drain Pump

  1. Place the new drain pump into the housing (making sure it’s positioned “square” in the housing – this will avoid leaks occurring) and turn it slowly counterclockwise until it clips into place.
  2. Reattach the wires back into the new drain pump. Make sure that they are locked into place correctly.
  3. Turn your dishwasher back on at the wall, and run it through a short rinse cycle. This allows you to check that the new drain is working and that no leaks are coming out of it.
  4. If the dishwasher drain pump is working correctly and no error messages appear on the control screen, you can start to put the dishwasher back together again.
  5. Start by reattaching the cover plate by threading in the two screws back in to secure it. The bottom part should clip back into place.
  6. Reattach the kick strip back onto the bottom of the dishwasher.
  7. Reattach the front door panel and secure it in place with the screws.
  8. Reattach the side panels and secure them in place with the screws.
  9. Reattach the top panel and secure it in place with the screws. The dishwasher should now be fully back together again.

Restart the Dishwasher

Now that the repair is complete, you can put the dishwasher back into place and reconnect the power and water hoses if you removed them. It’s a really good idea to now turn the dishwasher on and let it run through a wash cycle. This will let you know that it is operating correctly and see if any error messages appear. If the cycle runs properly, your dishwasher is now repaired!
