  • Silvia and the B-85 pump protector thermostat

    Can any one share with me instructions for installing a B-85 pump protector thermostat on a Rancilio Silvia?

    I am considering buying this one Rancilio Silvia Espresso Machine Parts: silvia pump thermostat ulka and Pump Protector Thermostat - Espresso Parts

    My story is typical. Silvia is connected to a timer so she is warm when I awake. My infant son flipped all of the switches one night, and by the time I woke up the next morning, it was too late. Now she is at a service center getting a new pump. You can imagine how much I miss having her! I don't want to give up the timer warmup and thought this protector thermostat might prevent another user error. Has any one installed one?

    IIRC the pumps plastic housing has a slot for the thermostat to slide into, wired in series with the pump by crimping on one female and one male 6.35mm spade connections to the thermostat wires

    I think the slot fits this style of thermostat? but I dont know the correct temperature

    eBay link removed per the

    Why not ask the service centre to do it?

      Unfortunately too late - they have already shipped it back. (That would have been a good idea)

      Any one else ever install one of these?
