Trying to save a bit of electricity, I switched the steam boiler off on my machine, but unfortunately the water tank empties into the drip tray if I do this while heating up.
If I switch the steam boiler on, then I get a bit of dribble from the drip tray waste outlet but as steam boiler heats this stops and machine works normally.
Anyone have any ideas? I’ve recently descaled it and changed the pump, and it’s run on Tesco Ashbeck since I had it (so pretty much scale free now)
I found some info on setting the expansion valve, but it doesn’t seem to work (pump pressure cranked up, blind portafilter and adjusted the EV right out and in, no water into drip tray, so I set it back to roughly where it started)
