hi,
I had a new UPS 15-50 hot water pump fitted by a plumber (I have a separate older pump for the heating) and on 4 occasions in the last month the boiler has overheated.
On the first two occasions I pressed the boiler override button to get everything working again.
On the last two occasions I noticed the new pump looked like it lost power (no lights). Overriding the boiler on its own didn't work on these occasions. the first time I had to cycle the mains as well and the pump came back on but this didn't work the second time and it came on about 48 hours later with out me doing anything.
If I wiggle the wire I can't get it to go on/off so I doubt it's a wiring problem.
I had a different plumber come and check the system (at a time it was working) and they reported everything was ok.
Any suggestions?
