HILl Spa sensors indicate that spa water temperature is rising above 112ºF. Unplug
spa and allow to cool down with cover off for one hour. Power spa back up and
reboot. If error returns, remove filter cartridge and check for clogged filter line.
Turn power off to spa, open access door and remove the four screws to the
metal control box cover. Look for sensor connected to heater plug and switch
it with sensor plugged into temp plug. Power spa back up. If topside control
shows water temperatures and error message is no longer displayed, sensor is
bad and should be replaced. Power spa down, place sensors back into original
plug locations. After replacing defective sensor, close box and access door.
Power spa up and set temperature.
Pb Miscommunication between spa side and board. Check topside connection
and connections to power board. Reboot system. If error returns, call technical
service.
ICE Water Temperature is below 50º F. Spa is running to bring water temperature up
to 60º F to prevent freezing. No action needs to be performed. Spa is operating
properly.

door and remove the four screws to the metal control box cover, remove the
fuse and check for continuity. No continuity replace with new fuse. Pump is not
running - disconnect power to your spa , change wires on relay switch from
horizontal position to vertical position, turn power back on, pump must turn
