The Spa Power controller has extensive self diagnostic capabilities. In the event of a problem it will indicate an error number according to the nature of the problem. The error numbers and their meanings are listed below. Note: When in an error state the alarm can be muted by pushing the AIR/AUX button.

Error 1 (H20) - Prime Failed

This is not necessarily a problem with the controller itself, but indicates that no water is being detected in the heater housing. Prime failed is a special case in that it can be recovered from by pushing a button.A push of the pump button will run the pump for 10 seconds to try to get water to the heater.If successful normal operation will resume. If unsuccessful, Error 1(H20) will be indicated on the display again. With any Error 3-8, spa operation will stop and not continue until the controller is reset. The controller can only be reset by pushing the UP, DOWN and PUMP buttons simultaneously. The controller will remain in an error condition even when reset at mains power, controller will only continue normal operation after the UP, DOWN and PUMP buttons are pushed simultaneously (see below).

Error 3 - Stuck Button

This error indicates that one of the buttons in the touchpad is stuck or has been held down for more than one minute. This may be caused by the pool cover pressing on the touchpad or by water getting into the touchpad or by damage to the touchpad or its cable. Try to reset the spa. If there is still a problem then contact your spa pool supplier.

Error 4 - No Water Sensor

This error indicates a problem with the optical water sensor in the heater. The problem may by caused by the sensor being disconnected or by damage to the sensor. Try to reset the spa. If there is still a problem then contact your spa pool supplier.

Error 5 - Overtemperature

This error indicates that the digital temperature sensor in the heater or pool has detected a temperature of 45°C or more.This may not be a problem with the controller, it may be caused by excessive pump use in hot weather, or pump failure. Turn off the spa and allow time for the water to cool. If there is still a problem then contact your spa pool supplier.

Error 6 - Thermal Cut Out Tripped

This error indicates that the safety electromechanical over temperature cut out on the heater has operated. This is not necessarily a problem with the controller. It may have occurred from an air lock around the element, high temperatures during shipping, or failure of the pump. This automatic cut out will only reset once the element has cooled below about 38°C. The unit must then be reset before it will resume operation. Manually push the UP, DOWN and PUMP buttons simultaneously.

Error 7- Stuck Relay

This error indicates a problem with the heater control circuitry inside the unit. Contact your spa pool supplier.

Error 8 - No Temperature Data

This error indicates a problem with the digital temperature sensor in the heater or pool wall or that both the in heater and in pool sensors are connected. Check that only one sensor is connected and that it has not become disconnected or damaged. Try to reset the spa. If there is still a problem then contact your spa pool supplier.

The Spa Power 800 controller has extensive self diagnostic capabilities. In the event of a problem it will indicate a warning or error according to the nature of the problem. The spa will continue operating if a warning is produced but user intervention or service is required for errors.

When in an error state the alarm can be silenced by pressing the SCROLL button. The alarm will automatically silence after four minutes.

Error 1 (“PRIME FAILED”) Water Prime Failed

Prime failed is a special case. This is not necessarily a problem with the SP800 itself, but indicates that no water is being detected in the heater housing. On a push of the DOWN button the main pump will run for 10 seconds to try to get water to the heater. If successful normal operation will resume. If unsuccessful, the error will be indicated on the display again. Note: When this error occurs you will also be given the option to run the SP800 in demo mode, this feature is not intended for end users. If you inadvertently enter demo mode, reset the spa to start over.
With any Error 3-8, spa operation will stop and not continue until the controller is reset. The controller can only be reset by pushing the Light Level, Light Effect Mode, Pump 1A and SPVSB buttons simultaneously. The controller will remain in an error condition even when reset at mains power, controller will only continue normal operation after the Light Level, Light Effect Mode, Pump 1A and SPVSB buttons are pushed simultaneously (see below).

Error 2 (“VS PUMP ERROR”) – Variable Speed Drive Fault

This error indicates that a fault has occurred with the variable speed drive. It may have occurred due to high temperatures within the spa enclosure, faulty connection, variable speed drive failure, or pump failure. Wait 20 seconds and try to reset the spa. If the error persists, wait 1 hour and try to reset the spa. If there is still a problem then contact your spa pool supplier.

Error 3 (“STUCK BUTTON”) - Stuck Button

This error indicates that one or more of the touch pad buttons is stuck or has been held down for more than one minute. This may be caused by the pool cover pressing on the touch pad or by water getting into the touch pad or by damage to the touch pad itself. Try to reset the spa. If there is still a problem then contact your spa pool supplier.

Error 4 (“NO WATER SENSOR”) - No Water Sensor

This error indicates a problem with the optical water sensor in the heater. The problem may be caused by the sensor being disconnected or by damage to the sensor. Try to reset the spa. If there is still a problem then contact your spa pool supplier.Error 5 (“OVER TEMP”) Over Temperature This error indicates that one of the digital temperature sensors in either the heater or pool has detected a temperature of 45°C or more. This may not be a problem with the SP800. It may be caused by excessive pump use in hot weather or pump failure. Turn off the spa and allow time for the water to cool then manually push the Light Level, Light Effect Mode, Pump 1A and SPVSB buttons simultaneously. If there is still a problem then contact your spa pool supplier.

Error 5 (“OVER TEMP”) Over Temperature

This error indicates that one of the digital temperature sensors in either the heater or pool has detected a temperature of 45°C or more. This may not be a problem with the SP1200. It may be caused by excessive pump use in hot weather or pump failure. Turn off the spa and allow time for the water to cool then manually push the Light Level, Light Effect Mode, Pump 1A and Pump 2A buttons simultaneously.
If there is still a problem then contact your spa pool supplier.

Error 6 (“THERMAL CUT OUT”) - Thermal Cut Out Tripped

This error indicates that the safety electromechanical over temperature cut out on the heater has operated. This is not necessarily a problem with the SP800. It may have occurred from an air lock around the element, high temperatures during shipping, or pump failure. This automatic cut out will only reset once the element has cooled below about 38°C. The unit must then be reset before it will resume operation by manually pushing the Light Level, Light Effect Mode, Pump 1A and SPVSB buttons simultaneously. If there is still a problem then contact your spa pool supplier.

Error 7 (“STUCK RELAY”) - Stuck Relay

This error indicates a problem with the heater control circuitry inside the unit. Contact your spa pool supplier.

Error 8 (“NO TEMP DATA”) - No Temperature Data

This error indicates a problem with the digital temperature sensor in the heater or pool wall. The sensor may have become disconnected or damaged. Try to reset the spa. If there is still a problem then contact your spa pool supplier.

Error 9 (“CLOCK FAULT”) Real Time Clock Failure

This error indicates a problem with the real time clock within the SP800. Try to reset the spa. If there is still a problem then contact your spa pool supplier.
Warning 1 (“TEMP SENSOR FAILURE”) - Temperature sensor failure
This warning indicates that one of the two digital temperature sensors in either the heater or pool is no longer functioning correctly. The spa is able to continue operating using the other sensor, however there is probably a fault. Contact your spa pool supplier.
If this warning appears when first commissioned it maybe that the controller needs to be set back to factory default. To set load factory defaults see page 29 of the manual.
SV Mini 1 Controller
For Mahoe (Twin) Spas and newer Hot Tubs
Full Manual
Full Manual

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.

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. Before attempting any troubleshooting always ensure mains power is isolated and turned OFF.

Heartbeat LED

All SV Mini spa packs feature a red flashing heartbeat LED light. The heartbeat LED is located on the main printed circuit board of the spa pack itself (spa pack enclosure cover needs to be removed).
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 Mini 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:
Heater sensor communication problem. Sensor cable is not correctly connected to spa control or is damaged
Solutions:
  • Turn mains power OFF, remove spa cabinet panel and SV Mini enclosure cover
  • Check heater sensor cable is firmly plugged into spa control socket labelled HEATER
  • Unplug and re-plug heater sensor cable to re-establish connection to spa control
  • Check for damage to sensor lead, replace covers and test spa again
  • Contact spa reseller if problem is not resolved

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 20-30 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.
  • Contact your spa reseller if problem persists

ER-5 Pool Too Hot

Problem:
Pool over temperature. Temperature sensor reading > 45°
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.
  • Contact your spa reseller if problem persists

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
  • Perform EPRM software reset to factory defaults
  • Reduce number of LED lights connected to spa control
  • Systematically unplug lights, keypads and expansion port loads from spa pack (one by one) to identify the faulty 12v device
  • 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 fault
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
