I have the same issue. I pulled the pump from the assembly and bypassed the circuit board inside by creating a circuit with the 2 black wires...pump worked fine. Of course, it won't cycle on and off so my guess is that the pressure switch somewhere in the circuit board is bad. Rule has a great warranty as my current unit is a warranty replacement (2 years ago). Last unit had a stamped date code on it. I contacted tech support (
[email protected] ) and got a new one sent out. The replacement did not have a stamped date code, so my fear is that they won't replace this one. I picked one up online for $99 and free shipping. If I get resolution on the broken on, I will have on as a backup.
Good luck and if yours is less than 3yrs old, contact tech support.
