Hope someone on here can give me some information and advice on my central heating pump.
l have a Grundfos pump which was on speed 2 but has now stopped on this setting, it will not work on speed 1 but works on speed setting 3 but it seems to be working slowly on this speed.
What do you think is the fault, windings burnt out , Can these pumps be dismantled to look.
If l need a new pump do l have to get a grundfos or are all pumps like for like in size and connections.
The pump l have is Grundfos UPS 15-50-x18 . can someone tell me what these letters and numbers mean..
l have seen many Grundfos pumps saying different like
UPS2 15-50/60. UPS 15-50 and 15-60
