how can it be a boiler fault when every tap is hot??? clearly its a fault with the shower??

check thermostatic cartridge to shower mixer

probably due to a blockage in the flue fan venturi. this device normally starts to get blocked after approx 5 years of use. not a difficult problem to solve but you will need to get a reistered engineer to carry this work out.

could also be a faulty thermistor or a scaled secondary heat exchanger. also check thermostat cartridge in shower
