my mira sport max is 18mnths old and has developed an intermittent problem. when switched on by pressing top button on the unit, the red light dims and there is a two or three second delay before it begins. it will not turn off at all and in order to stop it i must pull the cord switch on the isolator box.
this is urgent cos it is a rental property and i have guests saturday. i need a repair and i am willing to give it a go, but i dont know which parts to replace.
