How To Replace The Drain Pump In Your Dishwasher

Introduction

Replace the drain pump if your dishwasher no longer drains or shows error messages related to draining. This guide explains how to locate, remove, and install a new drain pump. Always unplug the dishwasher before starting and consult manufacturer instructions for warranty considerations. If you find foreign objects blocking the pump, you may not need a new part. If unsure, contact a licensed professional.

What you need

Step 1 Disconnect power for safety

Unplug the dishwasher from the electrical outlet to prevent shock and damage.

Step 2 Prepare the dishwasher

Lay the dishwasher on its back to keep water from leaking onto internal parts.
Place a towel underneath to catch any residual water.

Step 3 Locate the drain pump

Identify the pump near the hose connection or in the center underside of the dishwasher.
Check your model’s layout since some pumps are positioned differently.

Step 4 Access the pump assembly

Some newer models use a simple twist-lock design instead of screws.

Step 5 Detach the pump

Loosen the hose clamp carefully to free the pump outlet connection.
Pull the pump assembly out from its mount once all fasteners are undone.

Step 6 Inspect for foreign objects

Check the impeller area for debris such as rubber bands or small items.
Clean away any blockage to see if the pump can function properly again.

Step 7 Clean the old pump or buy a new one

Make sure that the pump rotates smoothly and is clean.
If you want to buy a new pump, take the old one to the store to make sure you get the right one with the correct connector.

Step 8 Complete reassembly

Install the new pump or the cleaned original pump in the same position as before.
Return the dishwasher to its upright position and reconnect the power.
Run a test cycle to confirm water is draining and no leaks are present.
Ensure electrical connector and hose clamp are secured firmly without leaks.

Conclusion

If the dishwasher still fails to drain after reinstalling or replacing the pump, consult the manufacturer or an authorized technician. Always review your warranty documentation before attempting repairs. Working on electrical appliances carries risks, so seek professional help if you are uncertain. Properly maintaining your drain pump can extend the life of your dishwasher.
