Miele Washing machine help please!

[Dave1962]

Miele Honeycomb W2240
This machine has been very good, but now doesn’t always drain.
I have checked and cleared all drain tubes and the pump appears to be working (although louder (at times) than it was).
Sometimes runs through a programme with no problems, sometimes stops on the 2nd drain.
Is this a mother board problem or pump?
Thanks,
Dave

there is a thin pipe coming off the pump chamber. it goes to the top of the machine and splits through a Y peice. remove and check this tube is clear as had a few pump out problems due to this

Is that the pressure switch?
I have checked the tube and it is clear, the pressure switch itself looks like its on the motherboard so not replaceable on its own!
Thanks

[electrofix]

no its a vent pipe to get air out of the pump
see pic part 21

Hi Dave, sorry for the late reply, ( I have been unwell but now ok and sorted it) and thanks.
It looks to have fixed the problem, i found most of the problem in the plastic pipe on the housing that the rubber pipe slides onto.
I have a problem with unbalance loads (towels mainly) in that the drum bounces around and hits the brake non return valve (some call it the water level air chamber) so hard that it breaks a hole in it and i now need to replace that! (aaaargh!)
Is this a common problem?

[electrofix]

never had the air chamber break

but if it bounces a lot consider and check the dampers. Non gen sets are quite cheap

any other gen only parts go direct ti Miele as its often cheaper

Thanks again, i will have a look.
would you do the springs at the top at the same time?

[electrofix]

no just the shock as springs often snap when they break so will not need doing

Have cleared out the pump vent pipe, and it was gunked up as was the plastic piece it slides onto on the pump,
Replaced the dampers and hooked the springs up a notch on the bracket.
3 washes done and looking good.
Thank you very much for the bits of advice, shame i cant rate your help anywhere!
Thanks again,
Dave

And then failed on the next!
I have now replaced the pump which has made no difference and also cleared the drum end of the sump tube where the ball is, again no difference, it is still randomly not draining , sometimes it will go through a wash no problem!
I have just done a ‘quickie’ rinse and spin and i drained it manually when i heard the pump start each time it needed to drain and that got it through the programme.
I could see the pump spinning but it wasnt draining, BUT i have replaced the black rubber tube from the pump to the air chamber which is new too, and i have made sure the external outlet tube is free running, so it is still a complete mystery!!
i think the pump was spinning clockwise and then next time anti clockwise which is wierd, obviously it was too fast to see but from the way the water was moving ( i had the filter cover off by this time!)
I will now swap the control board as there may be a ‘dry joint’ on there which would explain the randomness of this annoying problem!

[electrofix]

if the pump is running the board has done its job

its can only be the pump, a blockage or air locked
