℃
/ 000
℃
This code indicates a bad 20-40
℃
water temperature sensor.
Run the filtering function for 1 minute. If the spa display does not indicate an error code and the unit
is circulating water without issue, no further troubleshooting is necessary.
Remove the unit for further testing if Error Code 99 is confirmed.
Before beginning the test, ensure that the temperature sensor connectors are not loose.
1) Begin by swapping out the 20-40
℃
water temperature sensor. Disconnect the wire
connector for the sensor and clip on a new replacement
2) Run the control base on a spa. Change the PCB if the problem is not resolved. Follow the
instructions on
page# 33
to do this.
