[Weinsberg water pump]

The control panel is LT 315

I was posting this as you replied (and Ray it would appear) as I was doing some more idle research... ;-)

 

Have you got a download of the EBL251 manual? The diagrams in there reference the pin numbers. (If not, I can probably post a pic or a link - or at least a way to get a download from Schaudt).

 

BUT....

 

...are you able to post the model of Control Panel your 'van is fitted with?

 

Research into some of the panels fitted with that EBL indicate that the pump switch may well have a separate 12V supply in, not powered up the EBL to Control panel cable (I can't see that it is on the diagram) but sending power down it (the diagram implies that).

 

This would make a certain amount of sense, since that cable is probably not capable of the load required to run the pump, which is why it appears there is a relay/switching unit in the EBL which it does power at low current to switch a more capable circuit.

 

The reason I'm asking about the panel model is to ascertain whether there is in fact a separate 12v supply to the back of that switch, which would be a/the prime candidate for checking (given the lack of power and no indicator light) if there is.

 

(I'm currently looking at a version of an IT992 panel which appears to work that way - it isn't the correct version, but, combined with the EBL diagram and your symptoms, it's worth checking first).

 

Can you post a panel ID.

Thanks for this - how are the pins numbered? How do I identify pins 5 and 9?

Thanks for these replies, sorry I got caught up yesterday and couldn't respond. The Weinsberg is 2016 and the elektroblock is EBL 251. I had wondered about the existence of a relay somewhere, but having been assured that there were no faults in the elktroblock, Ive been searching elsewhere - with no joy :-(

Hi, the water pump on my Weinsberg Carahome has stopped working. The pump ( Barvig submersible) works if it’s connected directly to 12v. The water pump icon on the control panel is not illuminated. The leisure battery and fuses are all ok. The control panel and elektroblock have both been checked professionally and are ok. I’ve managed to check the microswitches on two of the taps and they are ok. Checking the shower tap means a fair bit of dismantling in the bathroom. Is the toilet flush part of the water pump circuit and could that be a problem? Any suggestions, what am I missing?
