Hello and thank you for taking the time to read this.
I was asked to help a friend out who has no heating or hot water due to H9 and L9 error codes on the boiler. This boiler is out of warranty and has had a catalogue of faults including flooding the kitchen.
We looked up the fault in the manual to find that we needed to check the resistance of the dry fire thermistor - after getting a reading of 885 ohms it was decided that this neede replacing. I can find plenty of spares for this boiler, along with many complaints but no dry fire thermistors. Any ideas or suppliers would be much appreciated.
