The EBL251 is (unsurprisingly) dependent on both the microswitches on the taps, and the pump being on, to deliver water. The pump switch, however, does appear not to be a simple switch, but to operate a "switching stage" within the EBL. It isn't clear to me what this actually is, because it isn't shown as Schaudt conventionally show relays, but its function looks very relay-like, and the implication is that it is an internal component. (It exists on some EBL versions, but not on others) If I were fault-finding, I think the first test I would do is turn on the pump and a tap, and test for 12V across pins 9 and 5 of block 6. If it is present, you can forget the EBL and look at the downstream wiring. If it is not, then the fault is within the EBL or the upstream wiring. As you aren't getting a panel light when the pump is on (I assume you usually do - and that other panel lights such as you have still function normally?) I'd not overlook the obvious, and suspect something in the panel to EBL connection. Unfortunately, the connections on the plugs for this are not easy to get a meter on to test. I hope the diagram (shrunk to meet post restrictions) is good enough to just about read. Edited to add: The manual for the EBL251 states "The power supply for the water pump is switched on and off by a switching stage in the EBL 251 electroblock via the operator and control panel connected"

The shape looks about right from reference pictures, but fitting and tinting might be different).

Further to the post above, the instructions in the referenced post point out that this is for IGO8-based devices. Following an exchange of PMs and data, it would appear that the POIs can, with slighlty different editing to that required for IGO8 (but using the same principles), be successfully used for IGO Primo devices also. When I have a little time, I'll update the instructions. ;-)

...as I've just posted a separate "how to" thread on POIs and IGO8 devices, I thought it would make sense to cross-reference it here. http://www.outandaboutlive.co.uk/forums/forums/thread-view.asp?tid=28149&posts=1
