    Hi again,

    I still think the board is fine, it's just not wired correctly. My guess would be that someone has mixed up the pump and the heater connections.

    So the machine is doing this:

    All probes grounded, thus heating should commence - control board runs the pump, but fill solenoid closed and heater off

    Safety probe and water level probe grounded, but fill probe open - control board runs the element and fill solenoid, but not the pump.

    ...make sense?


    *Please note this is just a guess, I don't have a wiring diagram for the BZ35/Minibar, I don't know the history of your particular machine, and your use of the above information is at your own risk. Please take great care when making connections at the control board and never do so under live conditions. If in doubt, refer the machine to a professional.

        Thanks for the electric design, I will try to figure it out. I own the Minibar for 12 years, the only changes could be on the controller wiring - see attached picture.
        So far it looks fine but will check it again.
        Appreciate if you could look on the picture and let me know if you see any wrong wiring. Thanks, aregev
