Yes although you probably have this fixed by now. Sounds like your sensors are bad, your filter is dirty(so there is not enough water flow) or one or both of your gate valves might be closed. My best guess is the sensor(s) is bad.

OH message showing on sundance spa sentry help!!!


If you are seeing OH and FLO codes, you need to shut it down at the circuit breaker, until it can be serviced. It likely needs a new circulation pump and the flow or pressure switch may be failing to shut down the heater causing the boiling

Hi have problem with canadian spa (balboa mrspa1) control panel digital reading when turned on goes to OH,circulation pump will not run


OHS, OH, or SPA TEMP LMT Message There is an "Over Heated Spa" (OHS or OH) Water Condition.

One of the Water Temp Sensors has detected 110°F (43.3°C) Incoming Water Temp and Spa Functions are Disabled. System will Auto Reset when Water Temp is below 108°F (42.2°C). Check for Extended Pump Operation or High Ambient Temp, or contact your Dealer or Service Organization.

Spa Water Cool Down
• In order for the Spa Water Overheat Error Message to Automatically Reset and Clear, the Spa Water Must Cool to below 108°F (42.2°C).
• Check the Topside Panel Display to see if the "OHS", "OH", or "SPA TEMP LMT" Spa Water Overheat Error Message has Cleared. If the Error Message has Not Cleared, the Spa Water is still too Hot to Continue Testing.
• Either Wait for the Spa Water to Cool Below 108°F (42.2°C), or Exit Now and Retest at a Later time.

My hot tub had a OH where the temp usually is, then went blank and i wasnt able to reset it. i just replaced the cord and resiliconed around the temp readout


This is probally your temp sensor. Where it is on your system is hard to say. If you have a book on the system it will be in there.

Reads OH but still cold


you either have a bad temperature sensor (check the wires for damage) or a bad circuit board. I would recommend replacing the temp sensor first. If that doesn't work, pull the board and take it and have it tested.

Over heating


Try turning the power off and back on again.

If this doesn't solve the problem you have further issues.

Our great lakes spa digital display flashes ''OH'' after a few seconds


sound like you probably have a bad temperature sensor, or high limit sensor. "OH" usually means overheat and will shut the heater off. Have the sensors tested and go from there.

QCA Opal hot tub display reading OH.


The tub experienced an overheat situation. This may be due to leaving the t stat turned all the way up and not monitoring or the hi-limit sensor is defective. The hi-limit sensor will shut down the heating cicuit if temp gets above 105 D optimally.the fact that the heater light is on is a good sign that things are working at this point.Whether or not a suitable temp(100-103 D) will be arrived at is to be seen. If spa heat kicks off before set temp is reached then replace hi-limit sensor.
