My bosch machine tells me that the pump is blocked but i have checked and it spins well. I checked the pipes from the drain, back through the machine to the pump. I have taken the back off, the rubber tube with the ball in it appears clear both under and above the ball. The pipe from this tube to the overflow had a bit of clay like stuff in it which i have removed ( but not much of it). Does anyone have an idea where I can look next for this apparent blockage. I am reluctant to take the bolt off that joins the rubber pipe to the drum but would that be the right thing to do ?
I would be grateful of some guidance as i am at the end of my tether !! 😉
Thank you
Re: Bosch WFR2860 Washing machine – Pump blockled
Does the pump actually run? That has to be the first step. With the machine empty and the filter removed, set the machine to spin – does the impellor rotate? “No” is simple – object jamming the pump, or pump failure. “Yes” is more complex…… A 5p coin will exactly fill and block the outlet tube from the pump. The anti-syphon bottle in the rear left corner of the machine can become choked, especially of you live in a hard water area. The water level control and level switch may be faulty. Finally, the computer itself may have decided not to play anymore – try not to think about that, as it’s damned expensive.
Few things to think about,
HTH,

The pump appears to run fine with the impellor apparently unrestricted.
I do live in a hard water area and have removed the anti syphon bottle. The Central bore was clear but the outer part of it was totally full of grey limescale could that have been the problem even though the centre bore was clear ?Re: Bosch WFR2860 Washing machine – Pump blockled

It certainly wouldn’t help so cleaning that thoroughly is the way to go. Paying close attention to also clearing the little black bleed hose to the dispenser. And making sure the dispenser end is clear too! 😉
My guess if the hose to the pump and the hose from the pump are now fully clear and you still have a problem? Then the answer is that the pump itself is knackered (excuse the technical term here? 🙂 ) Bearing in mind your WFR2860 is no spring chicken, pumps are only good for around 5 years – average. The impellor shaft gets well worn and has loads of lateral movement. Time to stick in a new one I reckon, try this link for a new one! 🙂
Re: Bosch WFR2860 Washing machine – Pump blockled
Thank you for your guidance 🙂 . The pipes are all completely clear and still comes up with the pump blocked remark on the screen. I have ordered a new pump and with a bit of luck that will do the trick…. if not then its a new computer ….or machine. At least i have learnt alot about the innards of a washing machine if nothing else 😀
Re: Bosch WFR2860 Washing machine – Pump blocked
Sounds similar to my problem which turned out to be the pump.
Re: Bosch WFR2860 Washing machine – Pump blocked
Did the drain pump sound noisy or rough before failing? Even My WFR2860 is requiring a replacement. Worthwhile as long as no issues with flashing displays/ saying Bereit(Ready in German)/ taking a while to come on.

*Thread revival!*
Hope no-one minds me bumping this post, there’s no conclusion posted (unless the new pump did the trick) so I’ll add my woes to here rather than start a new thread!
Anyway, my WFR2860 is playing up.
It stops during the drain cycles, and just hums. Initially, there was a bit of that grey clay semi-solid gunk blocking the rotor, which I removed and it worked fine. I ran the pump with the drain plug off and it span freely as I imagine it should.
it worked for a bit, then did it again, but there was no gunk blocking the pump, although the pipe from the chamber into the pump was furred with grey gunk which I have cleared as best I can.
Also, in the periods it is working, it sometimes detects foam (there is none) and goes into several extra unecessary rinse cycles.
Therefore my questions are:
A) Will an acid descale clear the grey gunk?
B) When the pumps fail (it is 7yrs old now) do they just stop dead or go intermittent like mine?
C) Are there any methods to troubleshoot the level sensor or the control module?Lastly if it proves uneconomical to repair if the computer is dead, do any of the professionals have anything to say about the new line of LG washers?

Can anyone advise how to get the pump out? Does the front of the machine have to come off?
Cheers
Re: Bosch WFR2860 Washing machine – Pump blocked
Just to complete this thread, I received the pump yesterday and fitted it.
Once fitted, the machine still struggled to empty, so I pulled the drain hose from the undersink spigot, and stuck one of those springy drain cleaner thingies down it.
Anyway, after a bit if clearing and pumping out into a bowl, it regurgitated 7 years of grey crud from the pipe, and now drains & functions correctly.
I can only think that the gradual narrowing of the pipe put more strain on the old pump, and eventually it just gave out. (Sorry to sound like a heart surgeon 😉 )
Thanks for the advice chaps, and sending the new pump out quickly too!
Re: Bosch WFR2860 Washing machine – Pump blocked
I found a 2p coin in the sump tube and a 5p coin totally blocking the waste outlet hose tube. I had to disconnect them from the pump and remove them with a pliers. Engineers told me i needed a new pump and they would charge over 80 pounds if they had to do it.
I was going to order a pump off the net but was glad i investigated further as the machine is now working perfectly. I found that removing and checking the pump to be very easy.
Therefore it vital that no coins and paper are in the pockets when clothes are being washed and that the filter is checked every so often.mark
