Re: Rangemaster induction 110 E9 code
E9 sensor returns implausable readings.
Suggests failure of either : the pot detector sensor, the temperature sensor or the control/power pcb.
Sorry but its unlikely this is going to be a ” quick fix “
Couple of things you can try…. Give the glass a good clean and buff up to ensure the pot n glass get a good contact.
Unplug the cooker from the mains supply ( or switch off the isolator ) leave for a couple of hours to fully discharge, then try again on the off chance the pcb might reset.
Other than that its a visit from a man with a van and lots of tools sorry.
