    Baxi boiler on the blink Error E133 22nd Sep 12 at 10:19 AM
    Our boiler has been on the blink since last week. As it stands we have no hot water or central heating.

    The boiler is a Baxi Duotec Combi 24HE.

    We keep seeing the error E133 (which in the book says 'Gas supply fault').

    So far our plumber/gas engineer has done the following:

    1) Replaced the flame-sensing electrode (paid him 50 including labour);
    2) Replaced the flame-sensing electrode lead (paid 11, no labour charge);
    3) Widened the gap between the flame and the electrode;
    4) Shortened the gap between the flame and the electrode;
    5) Cleaned out the condenser pipe (i think that's what he said)

    Now he thinks that the circuit board has gone.

    During the above he did call the Baxi call centre for support/advice.

    Any ideas? The boiler isn't that old - a couple of years at the most.

    Is it worth getting a second opinion or is this a foregone conclusion (i.e. yes it is most likely the circuit board)?
