    Convert i M20 to Rotary machine

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have a M20 with a defective printed circuit board. Unable to replace the board I would like comments on replacing the existing electric units to make it into a rotary pump machine with automatic touch pads. Any help on ideas and particularly suppliers would be much appreciated. Note: This topic posted in CoffeeGeek website.

    Correct. The machine is very erratic. It fills up the tank correctly, then overfills it.

    That looks like my La Cimbali M20 board (very poor quality photo) ::)

    Replacement boards are still available from La Cimbali agents - but expect to pay many, many hundreds of dollars for one!!! :(

    Someone elses board (costing just as much) could be used.... but the senders (flow meters for volume, water level sensor etc) would almost certainly have to be changed as well.... costing far more than the machine is worth....

    The other, and only low price option, is to turn it into a semi automatic.... i.e. no volumetric flow control. That is what I will be doing (when not if) the computer board in mine fails.

    Okay, so to turn it into a semi-automatic machine what would be the parts list? Apologies for the quality of the photo, I was trying to reduce it but havent got the knack of this system yet.

    sounds like the fill relay might be jamming
