Control Panel Display Messages
The following messages may appear in the Display Window:
“OH” – Overheat Warning
If “OH” appears in the Display Window, the 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 THERE ARE THREE FLASHING LIGHTS ON THE CONTROL PANEL. This indicates a problem with the spa.
If there are flashing lights, but the Display Window shows the current water temperature, there may be a water flow problem. 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 there is 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.
