help with windscreen washers please

Post by maurice the martian » Sat 30 Oct, 2010 16:33

Washers have stopped working,just a trickle comming out.Cleaned out the jets, made no difference,When you operate washers water is comming out of the little hole in picture. Nothing comming out of main outlet .Any ideas as to whats wrong would be appreciated

Had this problem a while back.

You need replacement washer jet valves. The white part in your photo.

Cost me £2.60 each from a BMW dealer so they don't exactly break the bank.

Maurice I agree with Turfalarian.
I replaced ours in the summer and would strongly recommend that you buy some new 8mm hose clips as well.
IIRC they were mega-expensive at 16p each but are much easier to fix and give a better seal than cable ties.
I tried re-using the old ones but only created an under-bonnet fire sprinkler system :!:

poor washers

Post by Antoninus » Sat 30 Oct, 2010 18:58

you'll probably find its not the exit part of the washer but the filters on teh black motors down at the water tank. unbolt the white tank, untwist the black motors and theres a mesh type attachment there. Wash it out well with soupy warm water, this bit stinks and is a bit like well, shall we say, drain glube. eh voila. all clear. put it all back together again and you'll be able to spray on demand fiercly to your hearts content. I usually do it in spring before the weather warms the water tank up. good luck. half hour job but really worth it! :)

Non return valves,so system does not drain back to reservoir.

So by taking these off would it be detremental to the system,or just take a while longer for the water to come through :puzzle:

I have not noticed any delay when they are operated and I have had plenty of other cars that do not have them fitted, they just seem to be more trouble than they are worth to me.

I have the same problem at the moment, water spraying everywhere under the bonnet from that little hole! One of my washer jets is working fine but the other is spraying out of just one hole so I think this is what caused the problem with the valves.

I'm going to get a couple of new non return valves this week and a couple of new jets to replace the blocked one so they don't break the valves again and all should be fixed :)

I tried running the washers without the valves and it seemed to work but couldn't really tell until I get some fully functioning jets. You should give it a try though, as tori says it should be fine.

The non-return valves leave the pipework full of water, so that when you operate the washers, water comes out immediately. The system would work without, but you would have to wait for the water to reach the end of the pipe before it will come out, which means more work for the pump.

It looks like overkill to me.Why bother fitting 2 NRVs when there is only one common feed?You can pick up a single straight male/male NRV for under £2 to do the same job as the 2 required by BMW.

Good point. Umm... you could do the same with the cylinders, why use six when four would do the job just as well.

I suspect maybe some would like to keep it all OEM!


Just kidding.

I suspect the two NRVs were cheaper than a longer hose. :wink:

After looking through RealOEM it would appear that Z4 and Z8 have no NRVs in the washer systems. :shock:

Also check that the washer pipe is not squashed as it passes through the hinge line of the bonnet

I agree with Antonius, I had the same problem and it was the filters at the bottom of the water tank that were blocked. I cleared them and within a couple of weeks had a recurring problem so this time I have used detergent to really clean the inside of the water tank. Everything working fine atm.

Can someone tell me, SHOULD water come out of those little holes in the back of the non return valves?
Had a blocked filter in the bottom of the bottle, which is ok now, got water spraying out of the jets ok, bit also water coming out of those little holes. The holes look like they should be there for a reason?
(Didn't realise this was such an old post!...anyway, I have removed the non-return valves, and all ok).

Models with heated washer jets have the non-return valve built into the jet. I have also found RealOEM and BMW dealer parts diagrams to be incomplete when it comes to the washer system. If you enter my VIN it look like it does not have windscreen washers at all.

Another area that can be an issue is where the hose routes around the bonnet hinge. There is a protection tube that can deform and pinch the hose. The hose can also pinch inside the protection tube and you can't see it. This was what has caused my washer issues twice now. The first time I repaired the tube by heating and reforming it. Since it did it again I purchased a new protection tube and some new hose. All good now.

Oh, and water is not supposed to come out of the little hole in the back of the valve.

I removed one valve and not the other before I realised that it was the bottle filter. The one sans the valve is a little behind the other in spraying but not so it would bother you so I haven't got round to putting the valve back. It's such a pain stretching under bonnet to work on them that I plead backache (laziness). :colourful:

Must be an autumn thing, had to get replacements for mine after nearside one failed and started to loose water out of the tiny hole. Did have a poke about and a good blow with an airline and got it to work again so haven't fitted the new one yet.
