Any help with this? The code says to clean my filter/strainer but all that looks good and I am getting plenty of pressure through the lines to the returns. I also tested the PRS switch on the heater with an ohm meter and when the pump is off, I get an open and when the pump is on, the ohm meter reads 0 ohm. So it appears that switch is ok. Not sure what else to try. Maybe I traced teh wires from the PRS switch back to the circuit board and re-seated the connector. When I do that, it usually works for a while but but within a few minutes of heater operation, I get the PRS code again. Possibly a bad circuit board/connection?

Anyone have any other ideas?
Thanks
 
You check the integrity of the wires in the connector for the pressure switch?

Maybe @swamprat69 has other ideas.
