Has anyone had issues with initial setup? I just got my 800 and I can't seem to get the boiler to fill. All settings are set for water tank mode. I will flip the machine on and hear the pump going but water in reservoir doesn't move. Keep thinking it's an easy button fix but can't figure it out.

Is there a lever underneath to move the valve from plumb to tank? My 700 does. That would cause the problem you are describing.

All fixed I had to open up the machine and reset the wires next to the boiler.

Time for some decaf:)
