How to Replace a Dishwasher Drain Pump

So you have identified that the drain pump inside your dishwasher no longer works and instead of choosing to purchase a new appliance - thought you’d have a go at good old-fashioned DIY. In the video, Josh will run through the steps to remove your existing pump and replace it with a brand new one.

However if the video seems to move too fast, don’t worry because we have broken down the steps in easy to digest bites. These helpful written steps, along with the video, should help you to achieve that ‘do it yourself’ scout badge.

It is worth noting that because you will be tipping the appliance onto its back, it is recommended to remove the baskets to help stop them from causing any damage inside the dishwasher.

This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.

What You Will Need:

Step 1 - Safety Advice

Safety is key! Now before you start, ensure you have unplugged your dishwasher from the mains or switched off the power (if your dishwasher doesn't have a plug).

It is also worth disconnecting the water supply hose from both the water supply and dishwasher. This will help stop the dishwasher from becoming damaged when you move the dishwasher around.

Step 2 - Position The Dishwasher On It's Back

You need to access the drain pump - to do this you’ll need to remove the base plate. This may require an extra pair of hands to help you lay the appliance on its back. Just be careful not to damage or cause injury to both you and your dishwasher.

Step 3 - Remove The Base Plate

Now it is laid on its back you will need to unscrew the base plate, once done, the base plate will simply pull away.

Depending on your particular model you may also need to remove all four legs in order for you to be able to remove the plate.

Step 4 - Remove The Anti-Flood Sensor

Now you have access to the bottom of your dishwasher you will need to remove the anti-flood sensor. This can be done by either unscrewing the entire sensor or by removing the electrical connectors instead.

A little eSpares Top Tip: If you decide to remove the electrical connectors, just take a quick photo of the how they are set - to remind you later of how they are connected.

Well done so far! At this stage, you're at the halfway point, so just a few more steps and you will have your dishwasher back to cleaning your dishes again no time.

Step 5 - Check The New Pump Comes With a Seal

When inspecting the new pump, check to see that it has a tiny rubber seal, if not, don’t fret because you can use the existing gasket that will still be sitting on the original pump.

Step 6 - Replace The Drain Pump

Unscrew and disconnect the electrical connectors on the existing pump before twisting it off of the lugs. At this point, you can replace the faulty drain pump for the new one.

Step 7 - Screw The New Pump In Place / Reattach Electrical Connectors

So now you have fitted the new pump into your dishwasher,  you simply need to screw it back in place and reattach the electrical connectors to the terminal.

Step 8 - Attach The Base Plate & Anti-Flood Sensor

Reattach the base plate back to the dishwasher, but don’t forget to also attach the anti-flood sensor onto the bottom of the plate.

Once the sensor and base plate is once again secured you can tip the dishwasher upright.

Congratulations! You can feel proud that today you not only repaired your dishwasher but also saved yourself the cost of a new appliance or an expensive call out charge.
