What does the message on my Gecko spa keyboard mean?


What does the message on my Gecko spa keyboard mean? - Click to enlarge

An error message appears on your Gecko keyboard and you don't understand what it means? Tubs.fr lists below the main messages you can find to solve the problem.

Note that the error messages are different depending on the model of control system installed on your spa. This list is still evolving and all messages may not be listed. Do not hesitate to refer to your manufacturer's instructions for use, and to  contact us for any request.

in.xm et in.xm2 control systems

Error codes indicate a failure condition or a problem which needs to be corrected to ensure proper functioning of the system. Both the error code and device identification are alternatively displayed.

When displaying errors codes, both device ID and the related error code are displayed alternately. If there is more than one active error, the one with the highest priority is displayed. If problems are found on several devices, the priorities are as follows:

  • in.xm or in.xm2 (error “SP” for spa pack)
  • in.therm (error “RH” for remote heater)
  • high voltage devices accessories (P1, P2, P3...)
Error message Meaning Corrective actions
SP - HR An internal hardware error has been detected in in.xm or in.xm2 Restart the spa pack and start & stop all pumps and blower.
If error reappears, replace the spa pack.
SP - BR The chosen input current rating is lower than the sum of current for all pumps.
  • Increase in.xm or in.xm2 current rating and breaker setting.
  • Increase breaker size and manufacturer's cable gauge or reduce pump size.
SP-Br is not considered an error code, therefore it doesn’t trigger the service icon to appear on display. Although SP-Br should be viewed more as a warning, it won’t allow the heater or any other accessory to come on if the amperage available is not adequate for the requirements.
SP - IN The input voltage is too low. Either there is a problem with the terminal connections or with the power lines. Check input terminal connections to make sure they are correctly wired & tighten (see connection section)
Have a certified electrician verify the quality of the power lines.
You should have 240v between L1 & L2 and 120v between each line and neutral.
SP - F1 in.xm or in.xm2 Fuse F1 is blown. Fan, blower, circulation pump, fi ber optic

Replace the blown fuse F1 with an identically rated replacement (SC-20, SC-25, etc.)
If new fuse blows, disconnect fan, blower, circulation pump & fi ber optic.
Replace fuse and reconnect all components, one at a time, until fuse blows.
Replace component that caused fuse to blow.

SP - F2 in.xm or in.xm2 Fuse F2 is blown. Pump 2, Pump 3 or blower that is more than 5 amp Replace the blown fuse F2 with an identically rated replacement (SC-20, SC-25, etc.)
If new fuse blows, disconnect pump 2, pump 3 or blower.
Replace fuse and reconnect all components, one at a time, until fuse blows.
Replace component that caused fuse to blow
SP - F3 in.xm or in.xm2 Fuse F3 is blown. Pump 1 Replace the blown fuse F3 with an identically rated replacement (SC-20, SC-25, etc.)
If new fuse blows, Replace pump 1.
SP - OT Temperature inside the spa skirt is too high, causing the internal temperature in the in.xm™ to increase above normal limits (overheat condition). Remove spa skirt and let system cool down.
A breaker reset may be required to clear error
SP - OH + blinking temp. higher than 112°F on the keypad display.
The system detects spa water temperature exceeding 112°F (overheat condition).
Remove spa cover and let spa cool down.
Add cold water and lower filter cycle.
If the temperature cools down within normal limits the error will reset itself.
If error persists, measure the temperature with a DIGITAL thermometer and compare its reading with temp. on the display. If temp. reading is different, replace in.therm
If problem persists replace pack.
FR - ER
in.xm2
The input frequency (50/60 Hz) is out of range. Was this error present since 1st power-up of the in.xm2? If so, have a certified electrician to verify the power line quality.
RH - HR A hardware error was detected in in.therm (related to the electronic circuit only). Reset main breaker; make sure the heater restarts by changing set point and turning every output On and Off (Pumps).
If problem isn’t corrected, replace in.therm.
RH - NH A "no heat" issue is detected. Verify if in.therm is properly connected. (You should hear a click!)
Reset main breaker.
Measure voltage directly on the Di connector (see p.28 of your techbook)
If you don't get proper voltage readings, reset the main breaker.
If you get an appropriate voltage reading, replace in.therm.
RH - NF This code is displayed when a “no flow” condition is detected by in.therm. Make sure water valves are open and that water level is high enough.
Check and clean filters.
Make sure there are no air locks (or that no object obstructs the passage of water in the in.therm™ channel). Pumps may make strange noises and error messages such as “P1 ER” could appear. Follow air lock procedure to clear them.
Make sure that the pump associated to the heater (Pump #1) is running by pressing P1 key.
If “P1 ER” appears on display, go to Pump 1 error section and follow procedure.
RH - NC Communication problem exists between in.xm or in.xm2 and in.therm. Make sure remote heater cables are connected properly and that none of the cable connector pins are bent.
If problem persists, either the spa pack or the in.therm may need to be replaced (both parts must be returned since either part could be defective).
RH - HL High Limit hardware circuit tripped.

There are 2 possible causes:
- The heater was previously stored in a very hot location prior to installation and there is no water yet in its tube to cool it down: Use a hose to cool down the interior of the tube.
- External ambient temp. is high enough to heat the water, even though the pumps remain off: Add cold water in spa and let heater cool down.  Reset spa pack using current breaker.

RH - PR The system detects a problem with the regulation probe. The system is constantly verifying if temperature probe readings are within normal limits. This error message clears itself when the condition that triggered the event is no longer present: Reset the breaker.
If problem persists, replace the in.therm.
RH - ID The system detects a no match between the in.xm or in.xm2 model and the in.therm model. The North American version of the spa packs can only be connected with the North American version of the in.therm heater. The same applies to the European version of both devices.
The RH-ID message indicates that the European version of the in.therm heater (in.therm CE) has been connected to the North-American version of the in.xm/xm2 pack (in.xm UL) or vice versa.
To correct the situation, swap the in.therm or the in.xm/xm2 for the appropriate version.
SC - ER System learning error. Every time a low-level option is changed, the system must “learn” the currents associated to each output/load. During this learning process, the device(s) connected to OUT8 (direct output, no relay) must be disconnected (or off). If not, the system will report this error. Once the load is correctly disconnected, a press of any key reset the learning process again. Once the learning is finished, the accessories connected to OUT8 may be reconnected.
AO - H
in.xm2
The in.xm2’s internal temperature is > 90°C. At this stage, only the Light output is disable. However, if the in.xm2's internal temperature continues to rise above 100°C (212°F), nothing will work. This error clears itself when the error condition is no longer present. Open spa skirt and let system cool down.
HR A hardware error was detected in the in.therm or the in.xm/xm2 pack. Add cold water to spa and let heater cool down. Disconnect the device(s) from the OUT8 (direct output, no relay) and reset the spa pack by shutting the breaker off than on again. If problem still persists, replace in.xm/xm2 pack. If not, reconnect the device(s) in OUT8 and reset the pack again. If the error comes back, replace the in.therm.
PR - R
in.xm2
Temperature probe defective. At this stage, only the Light output is disabled. However, if the in.xm2's internal temperature continues to rise above 38°C (100°F), nothing will work. This error clears itself when the error condition is no longer present. Open spa skirt and let system cool down.
P1 - ER System hasn’t detected any current change when turning Pump 1 on or off.

Make sure Pump 1 is connected properly (when connecting plug, you should hear it click). Manually change output status (on/off) of Pump 1 and cycle through all possible states (i.e. low, high, off).
Reset spa pack by pressing Select key twice.
If error does not clear, problem is most likely with Pump 1. It will need to be replaced.
If Pump 1 is replaced, a new learning routine must be performed.

P2 - ER System hasn’t detected any current change when turning Pump 2 on or off. Make sure Pump 2 is connected properly.
Manually change output status (on/off) of Pump 2 and cycle through all possible states (i.e. low and high speeds). Reset spa pack.
If error does not clear, problem is probably with Pump 2. It will need to be replaced.
If Pump 2 is replaced, a new learning routine must be performed.
P3 - ER
P4 - ER
P5 - ER
System hasn’t detected any current change when turning Pump 3 , Pump 4 or Pump 5 at on or off. Make sure the Pump is connected properly.
Manually change output status (on/off) of the Pump. • Reset spa pack.
If error does not clear, problem is probably with the Pump. It will need to be replaced.
If the Pump is replaced, a new learning routine must be performed.
CP -ER Circulation Pump not responding. Make sure Circ. Pump is connected properly.
Manually change output status by changing set point.
Reset spa pack.
If error does not clear, problem is probably with CP. It will need to be replaced.
If the CP is replaced, a new learning routine must be performed (see page 15).
BL - ER Blower not responding. Make sure blower is connected properly.
Manually change the output status (on/off) of blower. • Reset spa pack.
If error does not clear, problem is probably with blower, it will need to be replaced.
If blower is replaced, a new learning routine must be performed.
FN - ER Fan not responding Make sure fan is properly connected.
Manually change the output status (on/off) of fan.
Reset spa pack.
If error does not clear, problem is probably with the fan. It will need to be replaced.
If the fan is replaced, a new learning routine must be performed.
Replace ozonator par Fan.


in.xe, in.yj, in.ye and in.yt control systems

The error code and the water temperature are displayed alternately on the keypad. The error messages listed below display on the LCD and LED keypads. If your spa is equipped with a color keypad, please refer your techbook for more information on error messages.

Error message Meaning Corrective actions
Hr An internal error with the system hardware has been detected. First, restart the spa system, then, start and stop all pumps and blowers.
If the error comes back, replace the control system.
HL The water temperature in the water heater has reached 119 °F (48°C). Do not enter spa water! See below.
Prr The system detects a problem with the regulation probe. The system constantly verifies if the temperatures read by the probe are inside the normal limits. See below.
FLO The system has detected no water flow during the main pumps operation. See below.
UPL No low-level configuration is present in the control system memory, insert a valid in.stik to program the control unit. Insert a valid in.stik to program the low-level configurations in the control unit. Without them, the system cannot function.
AOH The temperature inside the spa skirt is too high and causes an increase of the internal temperature of the control system above normal limits. Remove the spa skirt and let the water temperature cool down until the error disappears.
Replace the control system if the problem persists.
OH The spas water temperature has reached 108°F (42°C). Do not enter spa water! See below.
