Heartbeat LED
All SV model spa packs feature a red flashing heartbeat LED light. The heartbeat LED is located on the front right hand side of the
spa pack itself (
installed underneath spa skirt).
The heartbeat LED flashes to indicate the current health/status of the spa pack. When the spa pack is functioning correctly with no
errors to report the heartbeat LED emits a single flash in a constant pulse much like a heartbeat (ON, OFF, ON, OFF). If the spa
pack encounters a fault the heartbeat LED will begin flashing in sequence with the error code number being experienced ( i.e. ER2 =
ON ON; OFF ON; ON OFF).
If the keypad display is ever blank a spa user can still determine the health / status of the SV controller by removing a door and
checking the heartbeat LED on the front of the spa controller itself.
ER-‐2 HEATER PLUG
Problem
: No heater sensor communication
Cause
: Internal heater sensor communication problem
Solutions
:
•
Turn mains power OFF, wait 5 minutes then restart spa
•
Contact spa reseller if problem is not resolved with power reset
ER-‐3 WATER PRIME
Problem:
Water prime failed – air detected in heater tube
Cause:
Airlock in pipe work, low water level, dirty filter cartridges
Solutions:
•
Press Pump A
button to retry water prime
•
Check spa water level (refill if necessary)
•
Remove filter cartridges and press Pump A
button to retry prime
•
Bleed airlock from pipe work by slightly loosening couplings on front of filtration pump or small plastic bung on the front
of Filtration Pump
•
Remove filter cartridges and flush water down pipe work with a hose
ER-‐4 THERMAL TRIP
Problem:
Heater thermal trip activated. Heater has been active and has had insufficient water flow over the element. Low or no
water flow has caused the heater temperature to exceed its maximum limits and the spa control has shut down operation to
prevent any damage to the heater unit
.
Cause:
Low water level, airlock in pipe work, closed shut-‐off valves, dirty filter cartridges, filtration pump failed or operation
intermittent
Solutions:
•
Turn mains power OFF and wait 10-‐15 minutes for element to cool and thermal cut-‐out device to reset. Then turn power
back ON
•
Check spa water level (refill if necessary)
•
Remove filters and clean as per manufacturer’s recommendations or replace cartridges if required
•
Check under spa cabinet to ensure all shut-‐off valves are in the OPEN position
•
Bleed airlock from pipe work by slightly loosening couplings on front of filtration pump, releasing plastic bleed screw, or by
removing filters and flushing water down pipe work with a hose.
ER-‐5 POOL TOO HOT
Problem:
Pool over temperature. Temperature sensor reading
≥ 45
o
C
Cause:
High ambient temperatures (especially in summer months) have caused water temperature to rise above set temp point,
Excessive filtration time, Jet pumps have been operating for extended periods with the spa cover still on
Solutions:
•
Turn mains power OFF, remove spa cover, allow spa to cool then turn power back ON
•
Check daily filtration time (refer filtration section) and reduce daily filtration time if required
•
Check spa cover is not resting on topside panel buttons causing jet pumps to start when cover is on. Use keylock function
to lock keypad buttons when spa not in use.
