I'll try to keep this short:
-Received from WLL last Wednesday, been working perfectly. Have Eric's Adapter installed, idle temps around 201F with boiler pressure set at around 1.1 BAR (I raised it, it was set at 0.9 when I received it with low grouphead temps)
-Last 48 hours, pump has not come on to refill boiler, ran out of boiler water today when running hot water wand, machine 'overheated' and the little red switch on top of the boiler was tripped. Re-set this switch but could not get boiler to fill.
-Found the water level sensor located on top of the boiler, pulled it out and reinserted it, voila, the boiler fills again.
-New problem: after this the vacuum pressure valve on top of the boiler would not close, so it would just keep releasing steam from the boiler, which would eventually re-fill itself. I disassembled the valve and put it back together and it sealed up, and boiler pressure rose to the normal level.
-Newest problem: boiler has been filling normally but the pressure has skyrocketed from 1.1 to 1.6 BAR and rising (I turned the machine off before letting it go any higher.) Tried dialing down the OPV (in case I had somehow managed to knock it earlier in the day, but I highly doubt this because of it's location relative to my other adjustments) but the OPV now has zero effect. Temperatures at the grouphead have also risen to reflect the change in boiler pressure, so the gauge isn't faulty.
Please help me, knowledgable people of HB! The machine has worked perfectly up until today, it's driving me nuts.
