I have a Baxi Combi 105e. The hot water and heating is on but the heating is not working. When I turn the temp up on the digistat the flame comes on and the heating comes on for about 5 minutes and then goes off. It does not continue to heat the radiators to the desired temp. The pressure on the boiler is fine and the hot water is fine. The wireless drayton digistat box says that the heating is on and that the radio signal is being received. Can you help? Thanks

theres a return filter on pipe that returns cooled water from rads.the cap on pipe on the right hand pipe.relive pressure in boiler by turning taps on the far left and right.the undo bleed valve.then undo cap on right pipe.baxi 105e .that was the same fault on my boiler

not sure it will be the pump as this will affect the hot water also , it would also wouldnt fire as the flow switch wouldnt make .... do the rads get warm at all ?...poss a faulty temp sensor ...... what temp does the boiler reach on the indicators on the front ?

not familiar with baxis,but it may be the pump is jammed and when heating is on for 5 mins the boiler quickly overheats as the pump cant get rid of the heat.try removing screw on the front of pump inserting a bladed/flat screwdriver and spin the pump to check if it is free/loose.
