Hi can you please help me as I have a problem with this boiler.
Problem is when you switch on boiler it is going on high speed and then
Slowing down and up again and then switching off and then little radiator is flashing on the screen then stopped flashing after that boiler is switching on again. That is happening for few times.
But sometimes when you switch on boiler it is going on high speed and then Slowing down and stay on slow speed
