I'm here with yet another waterpump problem, Vw Cali t6.1.
just over a year old, suddenly the water pump stopped working.
When i open the tap the water flows and than suddenly stops, with a warning on the control panel.
Saying waterpump error, go visit workshop, when I click ok, i can retry , again water flows for a random period (short) and than again same error.
Just before i encountered this issue, i had the cali at the dealer to fix the fridge, the lid kept popping open. As I understood they had to remove the entire fridge to replace the locking mechanism.
But because the pump was making weird sounds, my first guess was the waterpump.
So yesterday i replaced the pump myself because it's a cheap fix and didn't wanna take it to the dealer. And what do you guess? Indeed that didn't solve the issue.
I also checked the switch at the tap, by short cutting it, so the pump engages.
Same issue after a second or so.
I also checked for an air lock, the first time the water sputters, and the moment it starts flowing , the error occurs. So i blew some air through the water tap untill i could here bubbles coming from the watertank. Followed by sucking water from the water tap until it reached the tap. I than closed the tap, hooked up the power to the pump again. But still no progress.
Also tried locating the fuse for the waterpump, but never succeeded in finding it, undid all the fuses from below the seat, but it still kept pumping. Is the fuse maybe located in the dash?
My only guess now is that by removing the fridge at the dealer, they might have 'touched' something (wire?) and that it's an electrical problem?
I also wonder how does the control unit detect that their might be an issue with the pump?
Does it measure the amp's or something like that? Or is there a flow meter somewhere?
Any help would be greatly appreciated.
