This was a repair on a Vaillant ecotec Plus 831 in Sheffield, S11. The pump was still working but was failing and was making a rumbling noise at certain speeds.
On these models the pump can vary its speed depending on the load on the system. As such I have found that often they may run quietly until they run at a certain speed at which point they can be quite loud.
This is usually a straight forward repair, however one of the screws on the diverter valve decided it didn’t want to come out. I stripped the head on the screw as it was that tight, in fact I can’t remember the last time I couldn’t get one of these out.
No problem though, I just had to drill the head of the screw off and carry on. This only cost me about maybe 15 minutes but on a friday night at 18:30 it would have been nicer for the screw just to come out.
This pump was replaced there and then with a pump I carry on my vehicle for service and repairs.
