Hi Everyone,
I have a Myson Midas SI boiler which has a continuously running hot water pump (when hot water is selected in any form).
Have tried swapping the hot water inlet sensor with another (old) sensor, but it is no better - sensors read about 28k ohms, is this correct?
Have tried swapping main control board with another (old) board, but still the same.
LED 5 is on all the time as if hot water is being demanded.
Any ideas anyone?
Thanks (hopefully.)
