If my Boilers stat on the CH is turned upto full the after a wgile the boiler shuts off and the red light starts to flash and also does this with the hotwater. Also the downstair Rads will not get hot unless i turn them off upstairs even after bleeding them all.
If I turn the stat down it will stop the red light from comming on but the boiler does not stay lit long enough for the Rads downstairs to heat up but upstairs are boiling hot. Previously I had a problem with the hot water not working which was fixed for while by replacing the diaphram on the 3 way valve and changing the thermistors which work fine for a while except the Rads would get hot when the hot watre was on.
I think I need to replace the 3 way valve would that fix the problem or do you think there is something else wrong.
The fan comes on and the boiler ignights but the flam does not increase the same as it used to on the CH but does on the DWH and the pump sounds like it is working.
Please Help...
