Water pressure too low for my dishwasher, so it keeps filling?

9 replies
Found 31st Jul 2009
Hi, I just got a new dishwasher 2 or 3 weeks ago. Ive had 2 engineers out to look at it. The problem is it constantly fills with water and keeps filling with water and wont stop, overflows, even during a cycle.

The engineers are saying the water pressure is too low to close the inlet valve.I got confused at this when they said its a solenoid, if its a solenoid then how come it needs water pressure to close? Shouldnt rested be closed? Even if that is the case then why isnt the machine draining before it overflows during a cycle? On the cycle Ive been testing it on it starts at 58:00 - goes to 57:00 then jumps between them. Then floods my neighbour downstairs. Its managed to do a full cycle a couple of times though. On some other cycles its just a definate no go.

Its a Beko DWD 8657

Any help/advice appreciated.

Maybe its a faulty overflow switch.

Its supposed to have a flood protection system.

According to the manual for your model:

The water pressure from the mains supply must be with 0.3 bar min to 10 bar max pressure.

Hope this helps.

My Bosch was doing a similar thing.

Turned out that our drains were blocked and the unit could not expel the water properly. As soon as I fixed that it started working.

It was doing the same thing with the timer also.

Try taking the pipework off the back, my hunch is it will be lined with gunk, had to clean the washing machine pipes out the other day because they had become gunked up

is this a problem in your house or for your neighbours too?

this kept happening with my washing machine, it was caused by the waste pipe being too far down the outlet (if you get me lol) it was creating a syphon so teh water wouldnt stop flowing but it comes in quicker than it goes out! We just had to pull the pipe back up we held it to try it then tied it to teh back of the machie so it couldnt drop back down

Thanks for the replies. Im now going to phone up the repair place and if I get no joy 3rd time around I'll ask for a replacement machine and when it comes and if it works ... I'll put a huge-ass complaint in I think.

I live in a multi storey in the far north of Glasgow, and we get funny looks if we mention we have a dishwasher :-D

All the drainage is fine with all the proper parts used.

I.E. have others worked there before?Are the engineers telling you this on the phone or have they been round to your place to see it?What is the shop going to do about it?


This is our second dishwasher, the guys that done 'improvements' to our flat broke the last one. But we've had this place 6 years and the last one worked fine.

The engineers are coming out and immediately saying 'its the pressure'. Not one of them has had a screwdriver near it.

OK, 'Service Force' have said if I want another engineer out it will cost me £59 if they don't find anything wrong with it. So i phoned BEKO DIRECT and they've authorised a '3rd time lucky shot' as Im calling it.

Im confused as hell though ... how can they say it's the pressure when they havent even taken a screwdriver to it? Oh yea, it's their training.

I fitted it, but then again I fitted the last one in this house, the one in our last house, as well as the washing machine. Rebuilt the kitchen and bathroom, built a computer room, put a ring mains in the computer room, upgraded the breakers to RCBO's, do all the computer work and to top it I can cook some pretty good take away and gourmet food. I was also the person that worked out how to make the lines at IBM's Greenock plant more efficent for the laptops as well as discovering the major flaw in their software for the picking line.

But my main skills are in retail and people management, and I dont count the people management in how I deal with things on teh intrenet with its tubes. Done computer game reviews for a regional paper and national magazine at one point too.

Im a joiner, plumber, electrician, PC technician, av engineer, plant managing, shop keeping, tiler journalistic cook.

Nowadays though I do next to nothing. Im sat here at 1:30AM on a Saturday morning getting drunk and why? Because they cant work out whats wrong with my stomach and I can barely feel my toes. At the ripe old age of 32 Im basically retired with about 10 lifetimes of experience. I havent even mentioned working as an officer for the Post Office, working in a bonded warehouse or the fact I recently spent about £150 on electronics components so I can learn that while my body slowly eats itself.

The dishwasher is plumbed in 100% OK though, its not rocket science - which will be my next project after the electornics, well I will need to make a control unit of some sort for that and I got a credit physics

The ONLY reason we have a new dishwasher is because the housing assosiation decided we needed 'improvements' and broke the old one when putting it back in. I spent about £400 on our kitchen for them to replace the worksurface etc. when all we actually needed were new cupboard doors and some wall units (stuff we hadnt got around to replacing yet), dipsticks that they are.
