I have a problem with the pull cord switch it will not turn on the power for the shower unit. It operates off and on ok but shows no light indicator when in the on position and there is no light on at the shower unit. Could it be a fault in the switch ?
It has made some 'rumbling noises' in the past few weeks that I have thought maybe to do with other appliances using water at the same time
Its a Mira Advance shower and is at least 10 years old
All replys appreciated
