Just wondering if anyone can shed some light here?
All the fittings to the steam wand were clear.
The behaviour seems to be that once you prime the machine by running some water into the boiler from the pump, wait for a bit, the water inside the boiler mysteriously disappears?!
I suspect its flowing back into the reservoir through the OPV - certainly when I switch on the steam button quite a bit more water seems to flow from the OPV back into the reservoir to the point that the boiler must be empty and hence, no steam?
Any ideas on what could be causing this? Would it be a faulty OPV thats leaking or some other part?
