My water has stopped coming out of the taps. I've filled the water tank up and it is showing as full. Does that mean the water pump is broken? Is there anything I can check/do?

Is the pump making an noise? Had the pipes been emptied before the tank was filled?

Is the pump on?
Have you tried all taps?
Do other 12v items work?

12v. Lights all work. Heating works. Pump isn't making a noise. All trip switches are in the on position. It worked fine yesterday and has been no problem for weeks. Both batteries show as fully charged.

Sounds like the pump is the issue.
next step find the pump, and see if it has power.

The fuse is okay. I have a multimeter but don't know where to put it. The pump is the trumatic item that has the dump valve on right? That sits next to the boiler...

Can you see the power feed to the pump? Can you post a photo?

You may have a submersible pump in which case it will be in the water tank🤔

Some photos may help if possible?

Depending on the age, if it was working fine yesterday it probably isnt the pump giving up, most likely the power not getting to it. Need to check the fuse for the feed (if you have a manual for the electrics?). If you can identify the black and red feed from the pump, then test with the multimeter for voltage (with tap switched on/open). Check all the other taps too, incase its just a dodgy micro-switch. If all other electrics (12v) are all fine, then it is limited to the pump and tap switches, or wiring.

Your profile says a T337 if it's a Corado they have micro switched taps. If it's only one tap that is not working it will be the microswitch or the wiring in the tap. If no taps working either the pump of electrical supply to it.

The pump is in the tank. Hymer tandem. The problem affects all the taps. One tap suddenly just started working, but very weakly and the pump sounded strained and then stopped working. To my mind that suggests pump problem rather than electric supply?

Open the big cap, try to get the pump out or at least check for any debris blocking the inlet 👍

on the top of you tank there is a white cable with a blue and brown wire inside that go to the connector. This looks to me to be the supply to the pump.
If it is shove your meter across those two connections and operate a tap and see if you get 12v

That is the supply to the pump. Which wire blue/brown should I put the meter red wire on, and which blue/brown should I put the meter black line on?

Doesn't really matter I think as you would get a reading of 12v or -12v if there is power but normally blue to black.

I suspect your pump is goosed and you are going to need a new one🤔

It doesn't matter which because if the probes are the 'wrong' way round you'll just get a minus sign in front of the voltage displayed on a meter with a digital screen. If you swap your probes over you'll still get the voltage reading but without the minus sign.

So I've taken the pump out, and checked the voltage where the pump cables plug in. That join shows 12v. The pump is working intermittently when I wiggle the wires around. So that suggests a loose wire inside the pump, correct? Which means I need a new pump?

I assume you mean when you wiggle the wires into the pump body it is intermittent? Rather than the outside wiring on a connector? If so then I think they are sealed systems so will most likely be a new pump, unless you can see a way of taking it apart - although I suspect if it is serviceable it’ll need new seals any-way. Sound like a new pump in that case🥺

For only about another 7 quid you could fit a Shureflo pump and have a pressurised system & not have to worry about microswitch on the taps failing also you get much better water pressure.

This is how I did it on my van.

How long did it take you to move the steering wheel, gear knob and pedals. Thinking about doing that to my van so my wife can drive instead of me (y) I would complain you have been sold a duff van, proper German vans always come with the steering wheel on the left & a driver's door.:LOL:
