i have a baxi 105e combi boiler. the problem is when i turn on the hot water it fires up and the l.e.d's go all the way up to 80 degrees then it cuts out. This is in hot water mode. when i turn the dhw down to min it comes through warm then cold, if i turn it up to half way it gets very hot for about 10 seconds then lukewarm for 10 seconds and so on.
No faults lights come on and i have changed the plate heat exchanger , changed the dhw temp sensor, changed the safety thermostat, and checked the diaphram for any damage. It fires up ok fan and pump run ok but only for about 20 seconds before it cuts out , then after 10 seconds it fires up again. Could it be a gas problem, maybe a blockage, debris in the pipe or wrong gas pressure. appreciate any help i can get. darren
