Bosch pump faulty?

[lytham]

Hello all, I have Bosch WFF147S. My wife put a load of very sandy clothes in in and it has since failed to drain. I bailed the water out then pumped the rest out by hand using a sort of Diaphragm underneath the machine next to the pump (lost of sand came out). I then cleared out the filter which also contained a lot of sand. The machine still refuses to drain. Has the pump gone? If it has I think I’ve found the right part although I’m a bit confused as there seems to be a pump AND a drain pump listed on some sites I assumed there would be only one type of pump per machine.
Also, is there anything else that anyone thinks might have gone wrong other than the pump?

The pumps impellor must be free to rotate and the hose from the pump to the drain must also be clear. With the machine empty of water (and the power disconnected 😉 ) remove the filter cover and check the impellor behind is free to rotate? Also its a good idea at this point to blow down the grey outlet pipe to ensure that is clear? (That can only be done with the filter cover removed by the way!)

If the pump is in fact faulty then do please give us the complete E.Nr model number of the machine (on the inside of the door usually) and quote all those numbers 😉 )

Thanks for that. the impellor seems to be free and it turns. There’s a sort of white bottle attached to the waste pipe at the back of the machine (on the inside that is. I had to take the back off to see it) just before the waste pape exits and goes on to the exterior part of the waste pipe. What is is? And is it possible it’s blocked?

It’s acts as a air vent to counteract suds-lock during drain out (don’t ask – but it works 😉 ) And they do crud up quite badly and are a bit tricky (to say the least) to remove and clean. But likely as not, that will have to be done, paying attention to the short ‘bleed hose’ that runs to the dispenser too!

Rule of thumb: If you can’t blow down the hose, sure as hell water ain’t going to pass thru it either! :rolls:

Yes the hose seems clear. I hand pumped the water back through it to clear the drum so I reckon it’s ok

Hi
With the appliance unplugged :plug: , it may be worth checking the sump ball situated in the recess of the sump hose just below where it attaches to base of tank.
There is a chance that sand may have jammed the ball thus blocking the tank water off and stopping it reaching the drain pump assembly 😀

Would that be the squashy ball underneath the machine and towards the front?

Its certainly sounds like it 😀

Re: Bosch pump faulty?

Hello again, I’ve fitted a new pump that I ordered from this site (£40 cheaper than elsewhere thanks!). It fits perfectly, apart from a little jigging around with the electrical connector, but I noticed when I fitted it that the old one was 25w and the new one is 30w. Is that likely to cause a problem?

After one wash everything seemed fine and I felt very pleased with myself but today the machine seems to be jumping through its spin cycle or refusing to spin. All pipes are clear and the bottle shaped filter at the back is fine. Any ideas anyone?

Thanks as always

Re: Bosch pump faulty?

I’ve just bought a Bosch WFF2000 from gumtree. The owner was keen to show me it working (not plumbed in, in the hallway!) which I thought was odd – turned out it doesn’t drain.

It just made a vibrating noise when trying to drain
I tried the little drain pipe, nothing

Unscrewed the pump filter cover, and there was no water in it, the noise was the pump spinning round with no water in the chamber.

I spent a while groping the big hose coming from the tub to the pump, and I came across a ball shaped thing.

For the life of me, I couldn’t work out how the water was supposed to get out of the drum, when the bottom of the tub had this odd ball shaped thing; then I came across this thread, worked out it was a sump ball, and it was supposed to be squigy – mine was stuck fast. With a great deal of tugging, it suddenly became squidgy, and the hose filled with water – I turned it back on and it drained like a dream.

So – thank you very much for your help, even though you never knew you were helping me!

P.S> it seems quite gunky down there, can anyone recommend a chemical cleaner that will de-gunk a machine?
