SOURCE: cant turn heating off

do you have a separate or built in programmer? if itis separate ISOLATE MAINS undo the screws on the bottom of programmr and checkthat ther are no loose wires ( make a note of where they go for future ref. ). If wires OK check that the valves are working switchoff HW and Heating switch one on at a time and check that each valve is opening and closing and that the boiler and pump fires up ( it could b the micro-switch in the valve is broke! )

SOURCE: boiler cuts off after abt 20 secs of igniting,hot

Yes usually it is indeed the thermostat, or Thermistor, all part of the control circuit. You did not indicate what type of setup you have. I suggest you Google for a thing called a service manual. This will aid in diagnosis, and repair of your system.

Baxi duo-tec boiler - when water comes on flame roars up. When i put the heating on the flames roar for 5 minutes then die down.


is the boiler a combi if so have you checked the pressure. it needs to be at 1.5 bar 2 bar at the most . also check that the heat the boiler is producing is completeing the circuit on the heating if you have access to the pipe work there should be 2 or 3 22mm copper pipes. now turn the heating on and check which one is getting warm. the one that is is your flow and in about 2 to 3 min there should be one more pipe getting hot let me no if this is the case

Condensate pipe on baxi105he was frozen i have unblocked however still flashing fault led and not working


My Baxi also developed this issue about 1 hour ago. I have about 4m of pipe outside and the blockage is in there.
Inside the bolier on the right I have a clear chamber where the water gathers. Is this still full on yours? If so your blockage is not clear. If it is clear I reset my boiler by using the left most dial and turning it anticlockwise past water/radiator for 5 secs. Should fire up if all is |OK

Heatslave diverter valve


clicking rads are due to pipe expansion when getting hot.
If the hot water [secondary circuit] gets hot and the boiler stays on [does not keep going on and off] even with a constant low water flow then the diverter should be ok.
there is a valve to prevent the primary circuit [central heating] [ CH] from sending water to the rads. this or its control may be at fault.
both the
Both the CH pipes to & from the boiler should have manual valves to turn off. do this then try the hot tap-full on. If the boiler goes into overheat mode and the overheat stat kicks in to turn the boiler off -- then :-
Check also the heat exchanger, it may be furred up especially if you are in a hard water area. It means taking it off and manually checking [pour water through] If you're lucky it will be just muck to be forced out with hose pipe pressure, if not a new one

Combi worcester 240. Plenty of hot water when heating running bot only luke warm when heating off. The pin in diverter valve working fine and ive tested the switch and that is ok !! Anybody got any ideas....


what u need to do is let the flow and return pipes for the heating go cold they are normally the 22mm ones and if 1 gets warm when u run your hot tap then u need a new diverter valve. if they stay cold then u need to see if the boiler is igniting in hot water so turn off the heating and just run the hot tap to see if it ignites get back to me

i need to know boiler specifics- make and model but sounds like either the air pressure switch seized or the main printed circuit board, if the boiler has an overheat thermostat please ensure that the little red button hasnt popped out because this will prvent the boiler firing up- refer to the manufacturers instructions for location of the o/heat stat
