when opening the hot water tap to demand hot water, I have to turn the pressure up a great deal more than I used to in order to ignite the burner. The only other fault I had was to replace the fan unit as the bearing has worn out (replaced the bearing about 4 years ago). Can anyone advise ?

as usual with most combis the hot water is controlled by a diverter. thats your problem
