This isn't a solution, but a question after having the same problem and doing some troubleshooting. I removed the water pressure switch in the heater and turned on the pump and water flows nicely out of the copper tube for the water pressure switch. Next I replaced the pressure switch and removed the two wires and shorted them together, being as a switch is either on or off, shorted or open. I confirmed that the short is seen at the connector going into the control panel. I still have the low pressure light blinking. What now?
Did you ever get an answer on this? I have the same issue and went thru the same test as you. Thanks DRDid you ever get an answer on this? I have the same issue and went thru the same test as you. Thanks DR
Check your flow and pressure from the pump first.... May need backwash, skimmer/strainer cleaning.. If you get an error message, chances are the fuses are ok.
