    Potterton promax HE 24 unreliable please help

    All fixed; it was the water flow switch (dry fire protection); it would seem that I didn't need a new switch but to simply remove it and clean it of debris. The switch uses a hinged magnet to operate a magnetic reed switch and the magnet had iron oxide debris covering it, which affected the...

    Potterton promax HE 24 unreliable please help

    Had an engineer out today and he did a combustion check and all was fine. After some puzzeling and testing we discovered that dosconnecting the water flow switch caused the same lock out scenario, so it looks like a intermittant fault of the water flow switch. Just thought I'd let people...

I am happy to work on the electronics but as you point out only a qualified gas safe engineer should touch the gas systems. Can you give me an idea of...

    Potterton promax HE 24 unreliable please help

    Ok I'm stumped... My Potterton Promax HE 24 (Heat only) boiler started becoming unreliable with it starting to fire up less often without using the reset switch on the front. It has now basically got to the point where it won't fire without a reset or unless it has been on recently. Once...
