mira showere atl advance?

Hi Glen, Due to the complexity of this particular shower I would suggest you phone Mira direct as it is too much for me to explain here.
In our experience though the number 1 fault on an Advance (which is a superb shower) is generally related to the relay board of which there are two, as well as a number of micro switches, hope that helps
