Error Code E95
This code indicates very high water temperature which could be hot water or a problem with the 50 ℃
water temperature sensor.
Begin the test by installing the spa control base and panel to a tub filled with water to the recommended
level. Make sure that the water inside the tub is not hotter than 50℃. Turn on the spa control base. Run the
heating 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 95 is confirmed.
1) Begin by swapping out the 50 ℃ water temperature sensor. Disconnect the wire connector for the
sensor and clip on a new replacement. If E95 have been solved, reference E94 for more details on
testing and changing the upper temperature sensor.
a. Disconnect the flow sensor 50℃ on the PCB. Remove screws that hold the heating element
on the support base. Remove screw of equipotential bonding system.
b. Pull the pile out and use wrench to disconnect50 ℃ water temperature sensor
If the error continues to persist, then the PCB must be replaced. Reference the PCB replacement chapter
for more details.
