Potterton performa 24 he Eco - not performa any more

[Amin]

Hello experts, my boiler has packed up as it does every year when it is snowing outside.

It ignites, gas comes on, but then switches off after 10 sec. It retries 3 times and comes on with flame failure light. While it ignites, the burner light does not switch on.

I have replaced the PCB board, changed the electrodes, tested the aps, replaced electrode wires, and to no avail.

Any advise?

hane you checked your condensate pipe ?

I have, that was the first thing to check. In extreme cold the drainage pipe friezes over. The reservoir is empty and looks normal, pipe seems free from ice.

Last night, at around 11pm, this thing suddenly decided to start working, just when i gave up on it. This strange behavior happened before. I am now suspecting that gas pressure in the national grid is responsible. I wonder if drop in pressure due to high consumption in the city could affect poorly regulated boiled in my house. Does this sound plausible?
