7.0 Troubleshooting Using The Control Panel
.1 Control Panel Displays
Complete operating instructions for the control panel can be found in the owner’s manual. The hot tub’s self-di-
agnostic control system constantly monitors the hot tub for proper operation. When anything goes wrong, the
control panel displays a message for the user which may result in a service call. Refer to section 7.3 below for a
listing of error messages and probable causes.
.2 Control Panel Default Display
The control Panel displays the following information during initial start up:
1. The control panel displays the current software eprom revision, then
2. The control panel displays “888” and all of the indicator LED’s are lit, permitting visual in-
spection of all display segments and indicator lights for proper operation.
3. After the initial start up sequence ends, the actual water temperature is displayed. If the water
temperature at this time is less than the factory preset temperature setting of 100ºF (38ºC):
4.
The heater will turn on and run until the temperature rises to the factory preset temperature
setting, then shut off. The circulation pump remains on for 24 hour operation.
Approximately two minutes after initial start up, the first filter cycle begins to operate.
The filtration cycle
can be modified any time after the start up sequence ends. You will be able to select a pre-programmed filter
cycle and reset your temperature setpoint at this time (see page 22). Press either the COOLER
or WARMER
buttons once at this time to display the current temperature setpoint. You can change the setpoint by press-
ing either the COOLER
or WARMER
buttons within 3 seconds. Each button press increases or decreas-
es the temperature setpoint by 1º. Three seconds after the setpoint is set, the display defaults back to the actual
water temperature.
.3 Control Panel Status And Error Messages
Sn1 Nonfunctional Hi-Limit Sensor
Open or shorted hi-limit sensor. Heater is deactivated. Refer to test steps 1-2 below:
1. Turn off the main breaker to the hot tub. Refer to appendix page 55 for expected hi-limit sen-
sor resistance/water temperature values.
2. Remove the hi-limit sensor connector from the circuit board test point 10. Refer to pages
50-51 for your circuit board configuration. Set your ohmmeter to 100-200k range, then measure resistance
across the hi-limit sensor wires (see page 55). If the sensor tests OK, check the sensor connections. If the con-
nections are OK, replace the circuit board. If the sensor resistance is incorrect, replace the hi-limit sensor.
Sn2 Nonfunctional Temperature Sensor
Open or shorted temperature sensor. Heater is deactivated. Refer to test steps 1-2 below:
1. Turn off the main breaker to the hot tub. Refer to appendix page 55 for expected temperature
sensor resistance/water temperature values.
2. Remove the temperature sensor connector from the circuit board test point 10. Refer to pages
50-51 for your circuit board configuration. Set your ohmmeter to 100-200k range, then measure resistance
across the temperature sensor wires (see page 55). If the sensor tests OK, check the sensor connections. If the
connections are OK, replace the circuit board. If the sensor resistance is incorrect, replace the temperature
sensor.
