Step-by-Step Guide to Replace a Bosch Dishwasher Pump

1. Safety First

Before beginning any work, unplug the dishwasher from the power outlet and turn off the water supply.

2. Remove the Lower Access Panel

Locate the lower access panel at the bottom of the dishwasher. Remove the screws securing the panel and gently pull it towards you to detach it.

3. Locate the Pump

Once the lower access panel is removed, you will see the dishwasher pump located at the bottom. It is usually a cylindrical-shaped component with wires connected to it.

4. Disconnect the Wires

Carefully disconnect the wires connected to the pump. Use a flathead screwdriver to gently pry the terminals apart. Note the position of each wire for reconnection later.

5. Remove the Pump

Using an adjustable wrench, loosen the nut securing the pump to the dishwasher. Gently pull the pump towards you to detach it.

6. Install the New Pump

Insert the new pump into the designated space and hand-tighten the nut. Use the adjustable wrench to further tighten the nut, but avoid overtightening.

7. Reconnect the Wires

Connect the wires to the corresponding terminals on the new pump. Ensure that the wires are securely fastened.

8. Reinstall the Lower Access Panel

Align the lower access panel and gently push it back into place. Secure it with the screws removed earlier.

9. Test the Dishwasher

Reconnect the dishwasher to the power outlet and turn on the water supply. Run a short cycle to test if the dishwasher is operating properly.

Troubleshooting Tips

• Dishwasher not draining: Check the drain hose and ensure it is not clogged.
