Jandy JXi 260 260,000 BTU Pool Heater with High Efficiency and Digital Temperature Control PS Error Fix: Pressure Switch Fault

Error code PS on the Jandy JXi 260 260,000 BTU Pool Heater with High Efficiency and Digital Temperature Control means: Pressure Switch Fault. The combustion air pressure switch did not close (or closed when it should not have) — the switch verifies that the combustion blower is creating proper airflow through the combustion chamber before gas is released; causes include a failed combustion blower, a blocked exhaust vent (bird nests, wasp nests, leaves, or debris in the vent pipe), water pooled in the vent pipe from condensation or rain, cracked or disconnected rubber pressure switch tubing (the small hose from the blower housing to the switch), or a defective pressure switch; check the vent termination outside for blockages first; then inspect the rubber tubing connection
