Blocked washer jet

[Smudgemanuk]

The washer jet on my z3 is blocked

Does the white bit separate from the black nozzle?
Is the white bit a filter? and if so can it be cleaned?

Thanks Chris

The round white bit is a one way valve, disconnect the pipe and try blowing compressed air through it from base to outlet in the direction of water flow. Same for the actual jet part of it, the one way valve cannot be taken apart.
Replacements for jets and valves on ebay here, valves are inline versions and not the round type. https://www.ebay.co.uk/sch/i.html?_....m570.l1313&_odkw=bmw+z3+washer+jet&_osacat=0
There is a listing for the round type but at an extortionate price.

You can pull the white part out of the black "jet". Once out try the washers and see if water comes out of the one way valve. If it does, the jet itself is blocked. If so take a wire out of a wire brush and poke it into the 2 holes in the jet and blow through with compressed air.

i just removed both mine, and just have pipe to the nozzle, i did fit an inline motorcycle fuel filter on the pipe which works to stop gunge. and simple and cheap to replace

Just get fresh ones, I don’t think they are easy to clean or fix.

They're just the non-return valves.

Very easy to replace, and if you shop around, cheap to buy too. It might be worth checking where the blockage is by disconnecting each bit in turn and see if water gets through - just in case you replace the valve and it's the jet that's blocked.

Doesn't it take longer for the water to get to the screen? On my 1964 Herald it's a manual washer - hard to pump and drive at the same time - but the very simple system there is a glass ball in the jet itself. The water forces it up into the jet tube and gets past, and when the pumping stops it sinks down again and blocks the bottom of the jet so the water doesn't run all the way back. Dead simple!! Bet y'all didn't know that...

One of ours was removed by the garage when it sprung a leak on the day of the MOT test & we haven't noticed any difference.
