How to troubleshoot spa problems
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.
ER-6 12V OVERLOAD
Problem:
12V (port) current draw over 1A limit
Cause:
Total 12V current drawn by keypad(s), light(s), expansion ports and in
pool temp sensor is excessive, 12V power supply is overloaded, too
many LED light bulbs installed, faulty LED light
Solutions:
Turn mains power OFF and restart spa to see if problem reoccurs
Reduce number of LED lights being installed
Systematically unplug lights, in pool temp sensor, keypads and
expansion port loads from spa pack (one by one) to identify faulty part
Contact your spa reseller if problem persists
ER-8 CTRL FAULT HVS
Problem:
Heater relay is on when it should be off
Cause:
Power surge, periods of low or high voltage, water on spa pack
terminal block, relay problem
Solutions:
Turn mains power OFF and back ON again to see if spa control
recovers from ER8 fault
Inspect under spa cabinet for evidence of water leaking onto spa
control. If water present, turn mains power OFF and isolate, then
resolve leak, dry up excess water, and allow spa control to dry out
before restoring power.
Contact your spa reseller if problem persists
ER-10 OVER CURRENT
Problem:
Mains (230V) current draw above current limit (C.LMT) detected
Cause:
Accessory devices current draw is too large for the C.LMT setting,
faulty jet pump or air blower drawing excessive current, current
limit (C.LMT) settings are not configured to match circuit breaker
rating, load shed (L.SHD) and/or load limit (L.LMT) settings incorrect
Solutions:
Turn mains power OFF and back ON again
Check operation of each pump => attempt to identify problematic
pump or blower causing ER10 to occur
Contact your reseller to check controller settings are configured to
match available power and circuit breaker rating
