Control Panel Display Messages
The following messages may appear in the Display Window:
“OH” – Overheat Warning
If “OH” appears in the Display Window, your spa has overheated. DO NOT ENTER THE WATER. Remove the hot
tub cover and allow the water to cool below 110° F (43° C). Then reset the power to the spa by resetting the GFCI
breaker. If the problem recurs, turn off the power to the hot tub and contact your local Authorized Dimension One Spas
Dealer, or authorized service center
.
Flashing Lights on the Control Panel
DO NOT ENTER THE WATER if you see three flashing lights on the control panel. This indicates a problem with
the spa.
If you have flashing lights, but the Display Window shows the current water temperature, you may have a water flow
problem. You will need to check the water level and/or clean the filter.
The flashing lights should stop once the problem is fixed. If the problem persists, reset the power to the spa by turning
the GFCI breaker off then back on.
If the problem persists after resetting the power, contact your local Authorized Dimension One Spas Dealer, or
authorized service center.
Erroneous Temperature on the Display
If you see a temperature of 32° F (0° C) or 132° F (55° C), DO NOT ENTER THE WATER. The system has detected a
problem. The actual water temperature is unknown. Contact your local Authorized Dimension One Spas Dealer, or
authorized service center
