Have had an engineer out to it (not swapping parts out randomly myself) twice and so far he has changed the above mentioned parts to no avail, supposedly a vokera specialist!
So we think a ignition fault then do we?
When we have central heating on or sometimes when we turn on shower our boiler comes up with error code 01 and the led flashes red
We have tried changing the air flow valve and the gas valve and still have the problem
