Ok , we all need to fault find on his one, r u sure the pumps are actually pumping , often when they are bust,seized the impellor head will rotate but no liquid wil be moved , sorry about underlines I do not know how to switch them offI didn't end up spraying them - took the covers off and watched them as they switched on/off - both two way valves are working fine by the look of them.
The only thing I cant work out is why the pumps aren't pushing water around. As I said earlier they did light up - but haven't done since. I've been around the place, set the thermostats up/made sure that every switch I can find is set to on - made sure that the return valve on the heating loop is open etc etc.
Completely stumped.
I would and have done and am living proof , but yes for amatures is probably not a best thing to do..my approach is often radicalI would not spray any liquid onto anything that has 240v going to it but that’s my opinion.
Don’t care if your a pro or not. Still shouldn’t spray stuff that you actually cannot see.I would and have done and am living proof , but yes for amatures is probably not a best thing to do..my approach is often radical
But can work
Is there voltage to the pump? When the valves have motored?I didn't end up spraying them - took the covers off and watched them as they switched on/off - both two way valves are working fine by the look of them.

Probably a pump Issue but without a multimeter you cannot tell. Time to get a plumber in mate.They feel hot, but cant feel any movement or anything
Those grundfos pumps are absolutely *****, they were a quick and late design to get on the modulating pump market. Whip it out !!!!
