The function of a drain pump in a dishwasher is to remove water from the tub after each wash cycle. The pump is usually located near the bottom of the dishwasher and is connected to the drain hose. Over time, the pump may become clogged with dirt and debris, or it may simply wear out from regular use. If the pump is not working properly, water will not be able to drain from the dishwasher and it will need to be replaced. 

There are a few signs that indicate a problem with the drain pump, such as water accumulating in the tub after a wash cycle, dishes that are not getting clean, or strange noises coming from the dishwasher. 

If you notice any of these issues, it’s best to call a qualified technician to diagnose the problem and replace the pump if necessary. Or, if you’re DIY-minded, you can replace the drain pump yourself!

It can be a tricky repair to tackle on your own, but with this step-by-step guide, you’ll be able to do it in no time! Keep in mind that before you begin this project, you will need some basic tools and supplies. So gather up what you need and let’s get started!

Note: Before replacing the drain pump, which can be costly, make sure that the filters are clear of any debris. Often, this is the problem and simply clearing the filters will fix the issue. If not, then you can move on to replacing the pump. But by checking the filters first, you could save yourself both time and money.

You will need:

  • Channellock pliers
  • A flathead screwdriver
  • A nut driver with the appropriately sized attachments for your model (check your user manual)
  • A towel

Preparation steps

Step 1: Turn off the power to the dishwasher

You can do this either by unplugging the dishwasher from its outlet or by turning off the power at the circuit breaker. If you’re not sure which method to use, you can always consult your dishwasher’s owner’s manual.

Step 2: Disconnect the water to the dishwasher

To turn off the water supply valve, locate the valve under the sink. Then, twist the valve clockwise until it won’t turn anymore. This will shut off the water to your dishwasher.

Step 3: Remove the dish racks and empty any water inside the dishwasher

The water can be removed by using a shot vacuum, a small cup or even a turkey baster.

Step 4: Pull out the dishwasher

To access the drain pump on your dishwasher, you’ll need to remove any screws securing the dishwasher to the counter or cabinets. Then remove the screws holding the foot access panel in place. You may need to raise or lower the legs of your dishwasher to move it. 

Finally, pull the dishwasher out and lay it on its side. The drain pump is located near the bottom of the dishwasher. You should be able to see it once you have placed the dishwasher on its side. Be sure to place the towel underneath the pump at this stage to catch any water.

Replacement steps

Assuming you have successfully completed the preparation steps above, it is now time to replace the dishwasher drain pump.

Step 1: Remove the old drain pump

To remove the old drain pump, start by disconnecting the drainage hose using the Channellock pliers to help release the clamp. There will be some water leakage here.

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.

Use a 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.

Then continue by disconnecting any wires that are attached to the pump. Next, use a screwdriver or bolt driver to remove the screws that hold it in place. Be careful not to lose any of the small parts! With the screws removed, take the old drain pump off of the sump. This may require a bit of wiggling.

Step 2: Install the new drain pump

Now it’s time to install the new drain pump. Start by attaching the new pump to the sump, making sure that any screw holes in the frame line up with their corresponding places. A light twist may be needed to lock the new pump in place. 

Continue by reconnecting any wires that were attached to the old one. Then use your screwdriver or nut driver to secure the new pump in place with the screws you removed earlier. 

Reattach the drain hose and secure the clamps in place. Reattach the clamp securing the pump to the sump. Make sure everything is tight and in its proper place before moving on to the next step.

Step 3: Put the dishwasher back together

Carefully place the dishwasher back upright, and slide it back into place. Lower or raise the legs back to their proper position. Reconnect the dishwasher to the counter or cabinets. Reattach the foot access panel.

Step 4: Reconnect the dishwasher and run a test cycle

The last step is simply reconnecting your dishwasher to both the water supply and power source, then testing it out. Run a cycle and check for leaks or other issues. If everything seems to be working properly, then congratulations—you have successfully replaced your GE dishwasher’s drain pump!

If all else fails…

We hope this guide was helpful and that you are now able to replace your GE dishwasher drain pump on your own. If you have any questions or run into any problems, though, please do not hesitate to call a qualified professional for assistance.
