Siemens SE65E330GB – Leaking Pump

[Doug99]

My first posting and on this forum and I’d like to congratulate those behind the scenes for providing such a useful and informative tool for us DIYers.

My problem – My daughter’s integrated dishwasher pump ran continuously (even with door open). Having searched this forum, I identified that there was water in the bottom tray. Dried it out and the dishwasher appeared to work ok until the tray topped up again!

Looking underneath, there is water dripping from where the pump motor shaft interfaces with the filter housing. I have removed both side panels and even had the machine upside down, but for the life of me I cannot fathom out how to access the pump to reseat / replace the seals.

Grateful for any advise. Doug

This is a real swine of a job to do as you will need to drop the base to gain
access to remove the main circulation pump.

You can see some diagrams here which will help

You will need to remove the front plate and release the door catches on either side -you will see four screws(corners)

You should be able to drop the base enough to perform the keyhole surgery -you will need a jubilee clip to re-seal the outlet to the heater assembly.

The leak will be from either the main seal into the sump for the pump
or from the front housing/impellor.

I would recommend you remove the front pump housing anyway as
you may have corroded some of the motor parts (bearings)
Is there any evidence of brown stains on the tray below the motor?

If so the pump wont have much life left I’m afraid

If its the former often removing and rotating the seal helps or some
ptfe tape etc if its the latter then you will need to strip the motor down and
either try and reseat the main o ring or buy a new seal kit (prob about £35)

This is probably one of the most common faults imho with the Bosch/Siemens machines
-if the leak continues it will eventually lead to a complete pump failure and/or blown board.

I have spent quite a few hours trying to fix a similar machine recently -one tip is to leak test the pump housing prior to re-installing.

Nothing worse then struggling for an hour or two and then seeing the swine still leaking………

If you decide to have a go then please remove the plug first off course!

VMT CJAPeterborough – If there is one thing I have to my advantage its time and patience. I enjoy a challenge so here goes…..

I managed to remove the circulation motor and clean up the seals which had ‘gung’ deposits at the point of leakage. Refitted all and appears leak free but will wait a few days before buttoning everything up. No discolouration in the tray and the motor loopks shiney new, so hopefully I caught it just in time.

It was a long day, and facinating to watch the matrix and associated chambers/floats operating during a cycle; quite clever!

Minor problem now is that the dispenser flap will not slide shut. I may have obstructed the rear linkeage when I replaced the front panel. Thanks again.
