Bosch Wis24140Gb Pumping Problem
Hi all,
I have a Bosch WIS24140GB Logixx 7 integrated washing machine, nearly 4 years old and has been working fine. However, I am having a bit of trouble with it at the moment, this is what happens...
When the machine gets to the rinse stage after the main wash, it usually spins for a minute or so and it also does spins after each rinse, however now what seems to be happening is, the moment the machine begins to drain and spin, thick suds come pelting down the door at an alarming rate which causes the machine to abort the spin and then fill up VERY high with water in an effort to try and get rid of these suds, it then rinses with this high water, drains and tries to spin again, a lot of the time, when it begins to spin, suds once again come rushing down the door so it aborts the spin again and fills up hight again; the cycle continues. The suds seem to only just have cleared by the time it gets to the final rinse.
This effect can be reduced by adding some conditioner in from the drawer when it starts to rinse but this is wasteful and far from ideal.
The machine is regularly cleaned at 90ºc with biological detergent.
No changes have been made to the detergent we use (Arial), the detergent is never overdosed either, in fact we tend to use less than the manufacturer recommends.
I'd say it happes on about 7/10 loads of washing, we haven't really changed any of our washing methods etc, the machine never done this before.
Any suggestions as to what is the problem? It seems really wasteful and I wonder if filling up with such high water will put excessive stress on the machine.

Bosch WIS24140GB aborting spin due to poor draining from blocked sink trap spigot
- The problem
- A Bosch WIS24140GB Logixx 7 was repeatedly aborting the drain/spin phases during rinses. Thick suds rushed down the door as spin started, the machine then filled to a very high water level, rinsed again and retried the spin. This happened on most loads despite no change in detergent and no apparent overdosing.
- Likely cause
- Restricted drain outlet causing the machine to pump out too slowly. The accepted advice was to check for a partial blockage, and the confirmed blockage was in the sink U-trap/washer-dishwasher spigot area rather than the pump filter.
- What fixed it
- Drain and inspect the machine, then check the external drain connection. The pump filter only had a small amount of lint and the impeller turned freely. The successful repair was dismantling the entire U-trap and cleaning out heavy fluff and gunge from the end of the washer hose and the dishwasher/washer spigot, after which the machine worked normally.
- Checks to try
- Drained the machine using the small drain tube
- Checked pump filter for debris
- Checked pump impeller was spinning freely
- Advised to check grey drain hose for restriction
- Checked sink U-bend/U-trap
- Checked spigot and end of drain hose for fluff/blockage
- Parts or tools mentioned
- Pump filter
- Pump impeller
- Drain tube
- Wet vac
- U-trap
- Drain hose
- Spigot

If it isn't pumping away properly it will cause problems, I would check that there isn't a partial blockage causing the pump to pump out at a much reduced rate - Washing machine won't empty water properly

Thanks, I drained the machine with the little tube and help from my wet vac. The pump filter had a small amount of lint in it but nothing too dramatic, the impeller seems to spinning freely too and I had a good look in case I was missing something.
Will I right in thinking that the next thing to do would be to check the grey hose isn't restricted? Not looking forward to that though, the washer only just fits in its place, very tight squeeze.
If the washer pumps out into the u-bend under the sink check there first. Check the spigot for fluff and the end of the drain hose for small button.

The machine now appears to be working normally. I dismantled the entire U-trap and found loads of fluff and gunge had built up towards the end of the hose of the washer and the dishwasher spigot, I cleaned up everything and put it back back together and it seems okay
Thank you for the help.
PS, have you heard of any horror stories with these machines?
Thanks for the update: That spigot is a bugger for getting blocked. Very bad design. I used to cut out the plastic grid inside which just traps lint and cotton from the wash.

Hi guys,
(two years after the post but...) I currently have the New Bosch WAS32760 Washing Machine. I have checked all the u-bends filters etc etc but my machine is doing exactly the same (and its only 1 month old!). It starts the spin cycle at the end of the wash part, and then like someone else, suds come pouring down the front of the glass door. It then stops, and says that I have added too much detergent and runs additional rinse cycles. The problem is, that the machine has now been replaced and the new (same model) is doing the exact same thing. I cut down my detergent usage to almost nothing, and realised that actually it only "THINKS" Ive used too much detergent because it "THINKS" what is happening is caused by suds.
The issue is undergoing some sort of research by Bosch, but they keep wanting to send engineers round to have a look at the machine. My retailer is an absolute star and are trying to help sort this out. I love the machine, it matches my dryer (part of the reason I bought it) but does anyone have any tips on suggesting how to approach Bosch to tell them that its quite possible the pump is NOT powerful enough to cope with the water extracted from a 9kg Load!!?? All they seem to want to do when I talk to them is send an engineer round to identify the problem.....
Thanks!
