  • Bezzera B2000 left hand groip causing power trip

    Hi

    My B2000 2-group has started shorting recently when activating the left hand group. I have checked the button panel and it works fine when I try it on the other group (by switching the cables in the Brain Box), Could a faulty solenoid valve cause a short? Basically the machine works fine, but as soon as I try to use the left hand group, it trips the power.

    I had the same symptoms once from a Boema 2 group. It turns out the water inlet was turned off so the boiler was getting too hot, and since we favoured the left boiler it emptied sooner...

    Could also be a faulty element.

    Its a wild guess, I dont know much about these things!

      Yep most likely the solenoid. take it off and check if its shorted with a multimeter, but its almost definitely the solenoid,

        Thanks, I know its not the boiler or element, as apart from this problem, it runs fine. Ill pull the solenoid off and test it.

          yeah the only possibilities would be the touch pad, the main board or the solenoid

              Ok, sorry for the long wait on update, but turned out to be corrosion n the coil indeed.

              All good after replacing the solenoid coil.
