Redring slimline 650 electric shower
Shower stopped working during use. Basically the 4 control buttons to the front of the unit, top 2 there is no red light coming on and nothing else happening when they are pressed, bottom 2 red light is coming on when pressed but nothing else happening.
Nothing obvious when I look inside the unit. Solenoid was replaced about a year ago but apart from that it has worked perfectly well. Approx 6 years old
