    Hello everyone,

    I'm very puzzled with an error I have on my turbomax plus 824E,
    I would really appreciate if you could share your thoughts.

    I have an intermittent F22 error.
    The pressure is around 1.4bar.
    The pump seems to be rotating ok: it's vibrating, rotating but the body of the pump is always very very hot.
    I have replaced the capacitor but it didn't change anything.
    Also replaced all NTCs without success.

    the secondary heat exchanger is clean.
    when purging the boiler, the water is very clean.

    Do you have any clue ?
    Many thanks in advance
