Water Priming Mode
Purge air from plumbing system
TIPS ON FILLING SPA
•Before filling remove spa skirt and be sure that all valves in the plumbing
system are fully open to maximise the amount of air that can escape the pipe
work during filling
•Remove filter cartridge(s) before filling and be sure to fill the spa through the
filter itself to flood the pipe work with water and minimise the chance of air
pockets forming in the plumbing during the filling process.
•DO NOT fill spa by placing hose in the foot well. Filling a spa this way will create
a large number of air pockets in the pipe work and may cause difficulty when
priming. Always fill spa through the filter area.
•Once the spa is filled to the correct level attempt to power up the spa with the
filter cartridges still removed. Verify that the spa controller completes its
priming sequence and begins normal operation. Once normal operation has
been verified turn mains power off, re-install filter cartridge(s) and restart spa.
WARNING
RESTRICTION OF WATER FLOW DUE TO DIRTY FILTER CARTRIDGES IS THE MOST
COMMON CAUSE OF ER-3 FAULTS. IF THE SPA POOL HAS BEEN OPERATING
NORMALLY THEN INTERMITTENT ER-3 FAULTS START TO OCCUR THE FILTER
CARTRIDGE(S) WILL REQUIRE SERVICING.
DEPENDING ON TYPE OF FILTER CARTRIDGE(S) INSTALLED THE FILTERS WILL EITHER
REQUIRE CLEANING, SOAKING IN A FILTER CARTRIDGE DEGREASER SOLUTION OR
REPLACING. REFER TO SPA RESELLER / MANUFACTURER FOR DETAILS ON TYPE OF
CARTRIDGE INSTALLED AND RECOMMENDED CLEANING FREQUENCY & METHODS.
Every time the power is turned on the SV controller will initiate a water priming
sequence on start up. During a priming sequence the filtration pump will run for up to 20
seconds at a time in an attempt to purge air from the plumbing. The keypad display will
scroll PRIMING during this sequence.
If the spa controller is successful in clearing all of the air from the heater tube the system
will begin normal operation. However if air is still detected the spa controller will shut
down and latch on fault code (ER3-Water Prime).
How do I solve ER-3 WATER PRIME:
Press Pump A button to retry water priming sequence
Check spa is filled to correct operating level as advised by spa manufacturer
(refill if necessary)
Remove filter cartridge(s) and retry water prime
With mains power turned OFF, bleed airlock from pipe work by slightly
loosening couplings on front of filtration pump and allowing air to escape
With filter cartridge(s) removed use hose to flush water down pipe work in an
attempt to clear the air pockets from the plumbing
IMPORTANT NOTE
Do not allow the filtration pump to continue to run after five (5) x failed priming attempts.
Operating a pump without water for extended periods may cause damage to the pump.
Turns power off, wait ten (10) minutes and then try again later.
The in-heater water sensor constantly monitors the presence of water in the heater tube. If
at any time air bubbles are detected the spa controller will automatically cancel all current
operations and force a water priming sequence to begin. This will occur whether the spa is
in automatic mode or manual use. If the priming sequence is successful in clearing the air
pockets from the plumbing normal spa operation will resume in automatic mode. If
unsuccessful the spa controller will shut down and latch on fault code ER-3 Water Prime.

Error Codes & Troubleshooting Problems
How to troubleshoot spa problems
SV spa controllers feature self diagnostics and scrolling error messages to quickly
troubleshoot possible problems. Should the spa control encounter a problem the error
code / message will scroll across the topside panel screen until the problem is resolved. If
an error condition is experienced all spa functions are shut down and the spa should not
be used until the error condition has been resolved. A list of error codes with
descriptions of problems and possible solutions is detailed below for your reference.
IMPORTANT NOTE
For most error codes mains power to the spa control must be turned
OFF and then back ON before the error condition will be cleared.
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 (ie. 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 panel from the spa skirt and checking the heartbeat LED on
the front of the spa pack 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
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 or by removing filters and flushing water down pipe
work with a hose.

Error Codes & Troubleshooting Problems
How to troubleshoot spa problems
ER-5 POOL TOO HOT
Problem: Pool over temperature. Temperature sensor reading ≥ 45oC
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
