Can you run a spa without heat?

You can use a hot tub without heat, but do not cut power to the hot tub. You need the pump circulating the water through the filters to ensure proper water quality. Switching the mode to economy or sleep will reduce heating cycles and lower the temperature by as much as 20 degrees.

How can I tell if my Spa is overheating?

Press either the Temperature Up or Down button. While the temperature is flashing, press the Lights button. Keep pressing Lights until you get to the FLTR setting on your display. Press the Temperature Up or Down button until the display reads the current set duration (ex: “8:00” for EIGHT hours).

Is it normal for a hot tub to overheat?

That is not the case. It’s actually just the natural process of how the Arctic Spa’s designed to utilize that excess heat. So, if you’re running into this, where your spa is actually hotter than where you want it to be, keep in mind also that the spa is really designed to run at 100 degree or above.

When to turn off the heat in a swim spa?

If you only use your swim spa occasionally, you may prefer to turn off the heater in between uses and allow it enough time to heat up before you take a swim. For winter months, however, if you are not planning on using your swim spa, you should drain the water instead of switching off the heat.

Why does my hot tub have an OH code?

It is almost always a flow problem. When it’s not a flow problem, it’s usually a bad temp sensor, high limit switch or a stuck relay. Here’s another Cal Spa troubleshooting flowchart for spa error codes OH, including testing the spa heater element for excessive resistance.

What to do if your spa error code is Oh?

Here’s another Cal Spa troubleshooting flowchart for spa error codes OH, including testing the spa heater element for excessive resistance. This type of testing should only be done with the spa heater and all systems powered OFF, and only performed by someone who is qualified to test safely.

What does oh, ohh, OHS mean in Spa?

OH, OHH or OHS (o verheat) all mean that a temperature sensor has detected unsafe water temperatures of 108° – 118° F, and your spa is in an emergency cool down mode. The heater is shut off, and the circulation pumps and blower are turned on to help dissipate heat. Open the spa cover to allow excess heat and steam to escape.
