Hi,
I removed an old radiator (was tiling my cousin's bathroom) and replaced it with a new one. Now there's no central heating.
Boiler is a Baxi (no model details on the front)
Pump is a Grundfos one (gets hot to touch)
also has a Honeywell sundial Y plan 3 position diverter valve
When the water heating is selected the boiler fires up. When just the CH is selected the boiler doesn't fire up (just the pilot light on).
The water in the upstairs radiators gets luke warm to touch when the water is being heated but otherwise nothing.
I must admit to not knowing what to do now.
I have bled all the radiators to remove the air, I assume this was a success as water comes out of each radiator bleed valve now.
Any suggestions would be appreciated.
TIA
EDIT: I went over yesterday to test the white wire as suggested to see if I could isolate the problem. Before I did that I undid the big shiny round screw on the pump and some water came out - only enough to wet about a handspan on the floor then I put it back in.
Next I took the case off the 3 way valve to see if I could see a switch - couldn't recognise anything so I then took the front of the wiring box and got my cousin to switch the thermostat up and down twice so I could see if a signal was sent.
It was and now the CH works. Don't know why but we're both happy
Thanks for the help guys.
