Balboa Fault Codes - Aqua Design and Leisure

Here are the common spa panel messages that you will encounter with your spa panel. The spa panel messages include common diagnostic messages, operational messages, and various other messages such as reminders.
This is NOT intended as a service guide or a means for you, as the consumer, to service your equipment in any way. This information is being provided for information purposes only. Any and all servicing should be performed by a licensed spa technician. Failure to properly service or install spa related components can result in serious injury or death. DO NOT remove the protective covers from any electrical enclosure, or attempt to service any related electrical device, unless you are a qualified electrician or service professional.
There is no guarantee expressed or implied that this technology can detect all instances of a real or potential problem with the equipment. There may be conditions that exist in which the spa control system will be unable to detect these conditions. As a responsible adult, always check the control panel display for errors and verify safe water temperature before using a spa, and before allowing children to use a spa. Safety should ALWAYS be your first consideration!

DETAILED PRIMING INSTRUCTIONS

In Priming Mode, Nothing turns on Automatically*.
*Note: On the VS/GS Model, the Circ Pump will be on, and on some EL/GL Models, a continuous filtration pump** turns on automatically. Also, on the VS/GS Models, Freeze Protect Mode overrides Priming Mode, and All pumps will be on in Freeze Protect Mode.
The purpose of Priming Mode is to allow the user to manually verify that the pumps are primed (which typically requires observing the output of each pump separately, which is generally not possible in normal operation). Priming Mode lasts 4 minutes, but you can exit it earlier by pressing any Temp button.
**Note: The term "circ pump" refers to a low-speed-only pump that is used for heating and possibly also for filtering. If a continuously running low-speed-only pump is only used for filtering (not for heating), that is not called a circ pump, but instead may be referred to as a "continuous filtration pump".
You should verify priming on all pumps the first time you fill the spa with water, as well as each time you refill the spa with water (after having previously drained it). You can skip Priming Mode if you're restarting the spa for some other reason (without the water having been drained since the last time the spa functioned properly).
If you have a Circ Pump, do this first (EL version):
- Push the Jets 1 button once. This turns on pump 1, and also turns on the circ pump.
- Verify that both pump 1 and the circ pump are running and that water is flowing out of both their outlets into the spa. If they're not, or you're not sure that both are (because you can't tell whether you have two separate flows at different rates or just one flow), momentarily turn both pumps off and on (by pressing Jets 1 multiple times) to help the pumps to prime. Do not do this more than 5 times. Do not let the pumps run for a total of more than 2 minutes if they haven't primed by then. Observe the panel display as you do this. If you haven't successfully primed both pumps by the time the Priming Mode display ( Pr or PRIMING MODE depending on panel) ends, turn off the spa IMMEDIATELY.
If after two minutes you cannot verify that water from the circ pump is flowing because the water motion from pump 1 obscures it, press the Jets 1 button again until all pumps turn off. Then press Temp once to exit Priming Mode. Unless the water is very cold, only the circ pump will start for one minute. If you do not see water flowing from the circ pump outlet, IMMEDIATELY turn off power to the spa (as an attempt at heating will occur within a minute of the circ pump attempting to start). (It's 2 minutes on the VS/GS, and 2 minutes on EL/GL versions earlier than 21.) You cannot cycle the circ pump once you've exited Priming Mode, so go back to the previous step to try to prime it.

DETAILED PRIMING INSTRUCTIONS CONTINUED

If you had to turn off power to the spa before both pumps primed, leave the spa off (with water in it) for at least a couple hours, then try the whole procedure again. (Often just giving the water plenty of time to seep into every corner of the plumbing will take care of the problem.)
Note: The circ pump turns on by itself (without you needing to press a button). So before pressing any buttons, verify that water is flowing from the circ pump outlet. If it's not flowing after two minutes, turn the power off and let the spa rest for a few hours, then repeat. If water is flowing from the circ pump outlet, proceed to test all the other pumps.
If the Circ Pump is primed, or if you Do Not have a Circ Pump, then:
- Repeat the action above for each numbered pump, one at a time, by pushing its corresponding Jets button. If a given pump has two speeds, press its Jets button a second time to set it to high speed. (High speed should be used for priming.)
- When you have verified a pump is successfully primed, press its Jets button again to turn it off. Then continue on to the next pump.
- If the display exits Priming Mode and shows dashes or a temperature or a mode indication (such as Std or Ecn or SLP) before you have finished verifying that all your pumps are primed, turn off the power at the main power panel IMMEDIATELY, then turn it back on, to initiate a new pump priming mode.
Important: A pump should not be allowed to run without priming for more than 2 minutes. Under NO circumstances should a pump be allowed to run without priming beyond the end of the 4 minute Priming Mode. Doing so may cause damage to the pump and cause the system to go into an overheat condition.
If after repeated attempts (hours apart) you still cannot get all pumps to prime, consult a qualified spa technician.
Note: On the VS/GS, if you're starting with very cold water, you may not be able to verify priming easily because freeze overrides priming mode andturns on all pumps at once (and doesn't allow you to turn pumps on and off).

dr or HEATER MAY BE DRY WILL RETEST SHORTLY Message

There is Possibly a "Dry" (dr) Heater. Check for Water Level, Flow Restrictions, Closed Valves, Air Bubbles, and Pump Prime, or contact your Dealer or Service Organization.

Ecn or Ec Message

If the Ecn or Ec Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Economy Heating Mode.
If the Ecn or Ec Message is ON Solid (Not Flashing) on the Display, the Spa is Operating in the Economy Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles.
Ecn or Ec is Alternating with Temp:
The Spa is Operating in the "Economy" (Ecn or Ec) Heating Mode.
The Water Temperature is Sampled Only during Programmed Filter Cycles. The Heater will Only operate and Heat up to Set Temperature during the Filter Cycles. The Water Temperature will probably drop Below Set Temperature between Filter Cycles. Other Heating Modes are Standard, Standard in Economy, and Sleep Modes.
Ecn or Ec is ON Solid (Not Flashing):
The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode.
Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not Current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.

gFI or GFCI FAILURE Message

The Control System Could Not Trip the "GFCI" (gFI).
The spa has determined that a GFCI is NOT properly installed in the circuit providing power to the spa, because an attempt was made to trip the GFCI and the expected power shut-down did not occur.
If the spa is left in this state, no user functions will operate, but Freeze Protection remains active.
Cycling the power will clear the gFI fault and run the test again.
Once a properly installed GFCI is detected and trips at the exact moment determined by the system, the spa considers the test passed. On the subsequent power-ups, the GFCI test is skipped because the proper flag has been set in the software.
Note: The GFCI Test Feature should only be Enabled in the United States and Canada. Call Balboa Technical Service for Additional Help if this Spa is Installed in a country other uhan the United States or Canada.

Ground Fault Circuit Interrupter (GFCI) Trip Feature

Along with the EL Mach 3 System Software, a new GFCI Trip Feature is now available.
The purpose of this feature is to:
Verify that the spa has been properly installed in conjunction with a GFCI.
Allow the System to trip the GFCI in the event of an extreme overheat that is characterized by a stuck, or "welded" pump relay.
Note: Even though the GFCI Trip Feature may be available on a certain system, it can be disabled by OEM request.

Basic Functions When GFCI Trip is Enabled

The spa, when powered up at the customer's installation, will begin a GFCI Test countdown that can be factory set from 1 - 7 days. The GFCI can also be tripped manually via the Edit Menu interface titled gFC.
Button press instructions for initiating a GFCI trip manually can be found HERE.
If the spa is not installed with a GFCI and the system fails to sense a trip, the system will not allow the spa to operate unless a GFCI is properly installed.
If the spa water reaches a temperature of 110 degrees F, a "Stuck Relay Timer" will begin to count from 0 hours, while the system monitors water temperature over time.
If the spa goes through the typical Overheat Errors and continues on to exhibit specific temperature-rise-over-time requirements, the system will assume a pump relay is stuck ON, and has no ability to shut it off. In this condition, an attempt is made to trip the GFCI, which would shut off all power to the spa.

HFL, HL, or HTR

Possibly the "Heater Flow is Low" (HFL or HL).
During Heating, this message indicates a Possible Low Flow Condition. There may Not be Enough Water Flow through the Heater to carry the Heat Away from the Heating Element. Heater Start Up will begin again after about 1 Min. Check for Water Level, Flow Restrictions, Closed Valves, Air Bubbles, and Pump Prime, or contact your Dealer or Service Organization.
Check for All of the following Conditions:
Low Water Level.
Blocked Suction Fitting.
Blocked Skimmer.
Dirty Filter.
Too Many Closed Jets.
Closed Slice Valve.
Heat Related Pump Not Running.
Heat Related Pump Not Primed.

HOT or HOT-CALL SVC Message

A Pump appears to have been stuck ON before a GFCI trip, causing an extreme overheat.
If the extreme overheat conditions are determined, a spa with the GFCI Trip Feature enabled will trip the GFCI and shut down the power to the spa. If the GFCI does not trip for some reason, the gFI fault will appear and the HOt flag will be set.
If the spa is subsequently powered down and then powered up again, the HOt message will appear on the display and the spa will not be allowed to operate until a technician evaluates the spa and resets the HOt fault.
Note: The HOt message indicates the spa WAS in an extremely serious condition before power was shut off to the spa. It may be possible for a stuck relay to free itself after the power cycle, but the spa cannot clear the the HOt message without starting up in Test Mode first. A service technician must carefully evaluate the pumps and circuit board before allowing the spa to run again.
Check For Suction Blockage:
If the Spa with the "SF" Safety Fault Error Message has a pump suction blockage switch, Select "Spas with Pump Suction Blockage Switch" Below. If Not, Continue to Next Step.
Press Any Button to Reset and Clear the Error Message.
If the "SF" Error Message is not cleared from the topside panel display, contact your Dealer or Service Organization.

SnS or Sn Message

If the SnS or Sn Message is Alternating with the Water Temperature on the Display, it is a Possible Sensors Out of Sync Message.
If the SnS or Sn Message is Blinking or Flashing OFF and ON without showing Water Temperature, it is a Verified Sensors Out of Sync Message.

SnS or Sn is Alternating with Temp:

Possibly the "Sensors are out of Sync" (SnS or Sn) with Each Other. With the the Pump ON, prior to Heater ON, the Sensors differ by more than 2°F (1.0°C), indicating one or both Sensors are several degrees off. The Sensors are Possibly Out of Sync with Each Other, or Not Indicating Close to the Same Temperature at Both Sensors. Monitoring the Sensors will Continue for 1 Hour. Contact your Dealer or Service Organization.

SnS or Sn is Blinking ON and OFF:

There is a Verified "Sensors out of Sync" (SnS or Sn) with Each Other Condition. The "SnS", "Sn", or "SENSOR SYNC" Fault has occurred for more than 1 hour, indicating one or both Sensors are several degrees off, and Spa Functions are Disabled. The Sensors are Verified Out of Sync with Each Other, or Not Indicating Close to the Same Temperature at Both Sensors. Contact your Dealer or Service Organization.

Std, St, or STANDARD Message

The Spa is Operating in the "Standard" (Std or St) Heating Mode.
Between Filter Cycles, the Water Temperature is Sampled every 30 Minutes. The Heater and Pump will Operate Any time the Thermostat Demands Heat. The Water Temperature is Always maintained within 1°F (.5°C) of Set Temperature. Other Heating Modes are Economy, Standard in Economy, and Sleep Modes.
Note: On the Panels that Display the "Std" or "St" Messages, the Message will Only be Displayed for a Few Seconds After the Heating Mode is Changed to Standard from a different Heating Mode.

StU or STUCK ON Message

A Pump appears to be "Stuck" (StU) ON, and the Water is Too Hot.
If the spa is configured with the GFCI Trip Feature disabled or the system is not capable of the feature (GL Systems) the spa will not be able to shut itself down via a GFCI trip. In this case, if the extreme conditions are determined, the spa will display the StU message until the spa is shut down It will also set the HOt flag (HOt does not appear in the display).
In this condition, the water temperature is most likely dangerously hot!
The spa must be shut down immediately!
If the spa is powered up again the HOt message will appear on the display and the spa will not be allowed to operate until a technician evaluates the spa and resets the HOt fault by powering up in Test Mode (DIP Switch A1 on the System Board).
Note: The StU or HOt messages indicate the spa IS or WAS in an extremely serious condition. It may be possible for the stuck relay to free itself after the power cycle, but the spa cannot clear the the HOt message without starting up in Test Mode first. A service technician must carefully evaluate the pumps and circuit board before allowing the spa to run again.

Check For Suction Blockage:

If the Spa with the "SF" Safety Fault Error Message has a pump suction blockage switch, Select "Spas with Pump Suction Blockage Switch" Below. IfNot, Continue to Next Step.

Spas with Pump Suction Blockage Switch:

The "SF" Safety Fault Error Message indicates that the Vacuum Switch has closed, indicating that there has been a Suction Problem or a Possible Entrapment Situation Avoided.
Press Any Button to Reset and Clear the Error Message.
If the "SF" Error Message is not cleared from the topside panel display, contact your Dealer or Service Organization.
