Why does my calspa water heater overheat?

I found on my CalSpa if it was set at F6, F8, or FC, it would overheat the water and shut-off. This is because it requires an additional motor for those cycles. 2) Is the heater water filtering to fast?

What’s the code for a Cal Spa hot tub?

I’ve learned the F2, F4, F6, F8, and FC codes from Cal Spa’s current manuals. I get a OH code (I assume Over Heating) and the tub gets 108+. I have it set on F2 (sometimes F4: I understand F8 or FC can be a problem unless there is a special motor). However, the tub still gets to 105+.

Can a hot tub be in violation of CSPC?

UL has strongly advised that any hot tub or spa manufacturer that produces a control, or modifies a standard control, to exceed 104 °F is in violation of their UL listing and can have their listing pulled by UL. The actual 1980 CSPC cover letter that accompanied advisory #79-071 is listed below:

How to troubleshoot hot tub and spa equipment pack?

Using volt meter on a minimum 240 volt scale (120 on a 120 pack) check to see whether the power coming in is enough to power the pack: 210-240 on 240v, 110-120 on 120v. If not, have an electrician look into it. On 240v observe contactor or heater relay.

What to do if your hot tub cord is 240?

An economy spa cover is not going to provide the same heat trapping efficiency of thicker and denser spa covers. The R-value of the best spa covers can be 3x the R-value of a basic spa cover. Secondly, as spa covers age, they can start to take on water and sag in the middle. other covers begin to rip on the edges or along the fold.

Low water flow (LF, FLO), is the usual cause of an overheating (OH, OHH) spa or hot tub. When water doesn’t flow fast enough through the heater, the heater stays hotter, and the temperature of the water increases. Eventually, the temp sensors or high limit switches will detect the increased water temperature and shut everything down.
