I can leave it on for hours and it maintains pressure nicely, but after pulling a couple shots and some hot water, I often find that 5 to 15 minutes later the steam boiler pressure will slowl...

I got it working! After repeating all the previous troubleshooting steps and confirming continuity through all the wires and connections, I had a closer look at the board and found a 100ohm resistor in the sensor ground side that was open circuit. I tested it by manually paralleling another resistor...

I like what you're doing. Hope this helps:

2. Front feet are inset 2"
3. Feet are 1" tall
4. The front of the front feet is 14 1/8" from the back wall

I.e. volts between the probe and ground when the water is low. I am getting about 1VDC on open circuit and about 0.2 when the...
