Hi All,
This forum helped me a lot in the past and I am hoping that I can get help and advice this time .
I just noticed that UFH is not working and when checked the pump it appears it has no light on. It has been working fine for 8 years.
There is supply current and boiler control unit (Valliant VRC470) is showing pump status as ON, but there is no light, and pump is clearly not operating. All pipes coming in and out are cold when touching.
I am wondering if it is possible to replace the pump DIY and what would be the best way to do it without flooding the house?
Pump is located inside the base cabinet so access is not ideal but possible.
This is Grundfos UPS2 25-40/60 130.
Should I order exactly the same model or there are better/newer and possibly more reliable options which would fit?
Any help would be very much appreciated as it is quite cold outside.
