Screenwash problem

[fixitflav]

I have a Hyundai i30, 2017, 1.4 litre petrol.
Windscreen washers stopped working, motor runs so pretty sure it's a blockage. Put a hose in the reservoir and plenty of muck washed out, but it didn't cure it.
It's probably a blockage in the pump or filter, but the tank has to come out to remove the pump from it.
Tried to remove the tank, removed wheel and wheel arch liner. Removed 2 M6 bolts but can't get the tank out. It appears to pivot about something that I can't see.
Sometimes these things have a lug on the far side with a rubber grommet to go over a peg, but if so I don't know whether to pull it straight out, or up, or what. I've hoisted and levered it as much as I dare without breaking something but no joy.

I have a workshop manual which I downloaded a while back, but the pictures don't look like mine. For what it's worth, it's attached. It shows 2 bolts spaced horizontally, but on the car they’re vertical. I've been trying to find the correct manual online but no success.

I'll have another go at it tomorrow and take some pics.

If anybody has the right manual, or any suggestions that would be great!

Have you tried pins in the jets and vinegar in the tank?

I've tried poking the jets out. Haven't tried vinegar but I suspect it's too late for that.

Can you take the hoses off the back of the jets , and see if water comes out from there when you run it?

For the cost of cheap vinegar it’s got to be worth a try

I've seen steradent tablets recommended but haven't tried them myself.

You're right, I'll try it

Plenty of others to choose from…

Not really. I can prise the jet holder out, it's a rectangular plastic thing, but there's only enough hose to lift it about 40mm. The area underneath the jets is very inaccessible, and if I pulled the hose off the jet and the hose fell through the hole I'd be in a pickle.

I cured mine completely doing the following:
Empty tank completely, if you have a vacuum pump suck out as much as you can.
1 litre white vinegar in the tank.
A few drops on the jets and leave overnight.
Then next day try spraying in short bursts.
If even a little comes out, in the following few days keep spraying; don't do all at once otherwise you might kill the pump.
If and when all clears, finish using the vinegar and then replace with distilled water and concentrate liquid screen wash.
Do not use tablets or tap water.

I siphoned the water out, pretty sure as near empty as practical. A few more bits of black came out with it!
Added the vinegar, no results so far but I'll follow your procedure. Thanks

No cure so far.
I had another go at removing the tank but no success. I can see the point where it's attached, but can't tell whether there's a bolt or what. Pulling the tank out, up or sideways with plenty of force doesn't free it. It seems an odd design, with the 2 bolts on the front some sort of push-in fitting at the back would locate it securely.
The tank is translucent and there's black gunge on the inside, so I'd like to get it out to give it a good clean.

Is it held with one of these type of fixings

No, it's not that easy I'm sorry to say. There are several of those types of fixings for the wheel arch liner, which had to come off to access the tank. Even if it were that type, there's no way I can see to get at it to remove it, but I'd most likely have broken it with my efforts.

PS if the vinegar doesn't work I've a mind to try dilute hydrochloric.
