F13 fault with Saunier Duval Xeon Condens 30 HE?
I had a thermistor fault and fixed that. Now I keep getting an intermittant F13 fault.
Also the boiler makes a pop noise when it swicthes off.
The wiring appears to be intact and I have measured through with a meter.
Can anyone help me with this one please?
