ID: 175746

Description:

Steps:

1. Pump photo.

2. Teardown of the drain pump of a Bosch or Balay PANELABLE dishwasher; if it is a standard model with panels, you must remove the top cover and the right side cover.
3. Reason for the teardown of the pump: the machine does not drain, previous checks carried out in the:
4. Guide 1:

5. Teardown of the side covers and panels on the panel-ready model.

6. Teardown of the cover Torx screw using a T20 driver.
7. Lift the thermal and sound insulation cover upwards.

8. It is nearly impossible to fit your hand through the small remaining gap to access the drain pump, so you will need to remove the electronic module to increase the space.

9. To access the interior as well as to disassemble the electronic module, you must disconnect the external power plug.
10. Remove the top cover of the electronic board.

11. By removing the module's top cover, you can unclip and lift it to move it to the side.

12. Moving the electronic module gives us more room to access it with both hands.

13. Here we can see the drain pump from the right side; in photo 2, I have marked the pull tab that we must press "sink" in order to allow us to rotate it 1/4 turn and remove the pump.

14. Observing the pump outside the machine makes it much easier to understand why it gets stuck and cannot be removed without pressing the plastic tab.

15. Another teardown option we have is removing the protective plate and prying up the front panel skirt; we can also access the pump through here, but the upper locking tab is not as visible.
16. I'm sorry that the lighting in this series of photos wasn't as good as in the others.

17. Other views of the drain pump and photo 3, view of the cavity left by it.

18. Pump image; NOTE that it is 55 V AC three-phase, so we cannot test it electrically with any type of cable or transformer, as I have already tested this and detail it in another document.
19. Supplementary Video 1: In my case, the pump shaft had plastic and hair from pouring buckets of mop water into the kitchen sink,
