ER-2 HEATER PLUG
Problem: No heater sensor communication.
Cause: Sensor cable is not correctly connected to the spa controller or is damaged.
Solutions:

Contact your spa pool supplier.
ER-3 WATER PRIME
Problem: Water prime has failed.
Cause: Airlock in pipework, water level too low, dirty filter cartridge.
Solutions:

Check the spa water level and top up if necessary.

(On DuraSpas only) open the slow release valve on the filter housing lid to bleed any air out
of the system, and re-tighten.

Press ‘Pump A’ button to retry water prime.

Remove filter cartridge and press pump ‘A’ button to retry water prime.

Ensure waterfall (if present) is turned on.

Turn off mains, and restart.
ER-4 THERMAL TRIP
Problem: The heater thermal trip has activated. The heater has been active and has had insufficient
water flow over the element. Slow or no water flow has caused the temperature of the water inside
the heater tube to exceed its maximum limit and the spa controller has shut down operation to
prevent any damage to the heater unit.
Cause: Low water level, airlock in pipework, closed jet faces, dirty or clogged filter cartridge, pump
has failed or operation intermittent, closed waterfall.
Solutions:
 Check water level and top up if necessary.

Check all jet faces are in the on position.
