Help - Need some theories about root cause. For a few years now if machine is run until reservoir is empty, when I refill reservoir with machine on it will in one of 5 occupancies start an awful pump juddering. High frequency off/on of the pump. When it happens I open brew switch which forces pump on, once the low water in boiler is filled by pump I can turn off brew and all is well.
The scary thing is that when the juddering happens the pid display flashes off and on, and often the pid display shows version and doesn’t shift to regulating brew temp. In past 4-5 times that it happened I’ve been able to get pid working with pid reset and then waiting 30 minutes for it to start working. (Blue display pid on b2 upgraded). So, happened again a few days ago and pid seems stuck this time. Strangely pid display was blank for a few minutes before slowly brightening. I’ve ordered a new one but thinking something bad is happening with the pump judder and I should fix that too. I don’t want to kill another pid. Anyone experienced the judder? Is it a problem with low water switch? Or maybe with solenoid? Some feedback between pump and low water switch? Seems maybe a short since pid display is flashing dark indicating low voltage. -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
