Windscreen washer

[matrixjs]

My front windscreen washer has stopped working, when you pull lever you hear motor but nothing comes out, the rear works fine. Would this be a blockage or a faulty pump? Don’t want to rake it to stealers and spend a fortune really. Car is a Leon Fr mk3 2016

I suppose the first question could be "have you been keeping the washer fluid conc increased for this cold weather?", if not, the washer fluid has probably gone sludgy or partially frozen and that has caused a tube to get forced off.

I only filled it up Wednesday with autoglym screen wash half a bottle then filled up with water, the back works fine, I will have to check the nozzles on front as I did a 150 mile drive today and it worked fine on front for the first 100 miles then failed

Hose off nozzle and check flow?

Thanks I will have to check all this when I get home as I’m away overnight and got the 150 drive back tomorrow, at least they forecast rain so won’t need it!

It seems it’s just the nozzle jets that are blocked both sides, I always seem to have this problem unless I buy the screenwash from Seat or VW as the same thing happened with my old Golf. Any other screen wash seems to clog them up.

I've always stayed lucky using Holts when it was about, and now Prestone. It might be down to if you are in a hard or soft water area, I'm lucky in that I'm in a soft water area.

Yes it could be that I live in a very hard water area

Many Leon owners including myself have made the easy upgrade from the 3-jet standard Leon nozzles to the Golf fan nozzles, which give a much nicer spray pattern and don’t seem to clog as easily. About £30 for both jets from a VW dealer and an easy fit.

See this thread on how to do it.

Thanks for that I will look to buy some of those, would using distilled water with some screen wash stop the clogging up?

 

[RUM4MO]

I'd hope so, if buying "ready to use" washer fluid is not cheaper.

Use to keep a cats whisker to clean mine with in the car. Handy little things . That's if you got specific nozzles to get at. Was an Uno.... need a white cat ideally .

Using the same brand of screen wash constantly is good, some react to each other and form jelly in the bottom of the bottle, washing out the bottle maybe once a year is also good, open hose stuffed down into bottle and flushing clean is one way, just a oft forgotten bit of maintainance.

I inherited a few big containers of screen wash from my deceased brother (Aldi stuff pre mixed, he'd buy them in the post winter sales). The bottom of those contain settled sludge. Unopened have gel and sludge in them. Suggests the fluid decomposes with age.

On the Ateca possible Leon 3, the filler entrance comes with a removable plastic filter that you can wash out, reverse and rinse. Gundge getting into the system via pouring it in must be well known or people just poured foreign bodies into the system. I give the filter a wash out when I see anything there. This is a new invention that came along at sometime. The Altea was just slop it in, no entrance filter. Think the nozzles have changed over a period of time to bigger ones in cars with more pressure so less blockage in the nozzles. But as you said gundge in the pump you wouldn't want.

I've had the rear pipe way back on the Uno freezing up on the back window and dropping off as other have said. Moral here always use the winter mix in winter if it's a frozen pipe. You don't want pipes being blown off at junction points due to them being frozen.
