My machine has been working sporadically the last week or so. I’ve had two leaks on top of the service boiler, one was a probe, I was told to use ptfe and this stopped leaking. Next the brass fitting in the middle leaked rather badly, I turned off the machine and let this puddle evaporate.
When I turned the machine back on both boilers it tripped out, I then turned it on brew boiler only and it was fine. I unplugged the red wire, I assume to the element and started the machine on both boilers, all good. Putting everything back to normal the machine tripped again.
