Tap flashing fixed – my pump heater had failed which burnt out tracks the components on the main board, the high voltage had jumped across onto the grey wires and damage the main board. Repaired all the burn out resistors but no luck. Checked the front control panel and a diode had exploded. Ordered new front control panel and main board. Flashing red tap – I checked float switch and wiring. Checked flow wheel and reed switch clicking. No voltage to Aqualock hose.
Tap still flashing – checked inlet filter at tap ok, checked resistance of Aqualock which was about 3k ( this ok because it works In the end)
Went right back to basics and traced all the wires including the door switch expecting it to be a reed switch – it’s not ! It’s massively over engineered, It’s a tiny circuit board about 12mm wide with a Hall effect chip on it ! – guess what it’s connected to the blown components on the main board. Ordered new door sensor which fixed the Flashing tap – the machine started to work
