What to do if your hot tub stops heating

PANIC!

No.. just kidding. You don’t need to panic. In the rare case that your Hot Spring, Caldera or Sundance spa DOES stop heating, know you’re in good hands. First of all those 3 brands have the BEST warranties in the industry, and even if your hot tub is out of warranty, our service department has highly trained service technicians who can take care of your spa quickly and efficiently!

In the cold season, you do need to remember a few things if your hot tub stops heating:

  1. Don’t panic!
  2. Contact our service department if you’re a Spring Dance Hot Tub’s customer OR contact the service center where you purchased your spa if you’re outside of our area.
  3. Do not under any circumstance drain your hot tub! Especially when the temperature drops below freezing, you could be doing MORE damage to your spa if it’s empty and the plumbing lines are still filled with water. And freeze damage is not covered under ANY warranty!

After the jump, read some suggestions for hot tub heater fixes!

Why is my heater not working!?

Without a service technician checking out the heater element of your hot tub, it’s hard to know for sure, but if you’re experiencing intermittent heating issues or your spa is taking a long time to heat, it may just be a simple fix:

If your heater is cycling on and off continuously: You could have a dirty filter! Try cleaning your filter cartridge(s) or try our simple filter test. In rare cases, you could have a low water level. If your spa’s water level looks unusually low, trying filling the spa a bit to see if the heater kicks on continuously.

If your hot tub is taking a long time to heat: You could have a bad thermostat or hi-limit switch in your spa, but it won’t hurt to try the simple filter test here as well. This could also be the result of a dirty filter.

    My Sundance Spas 780 Dover hot tub the water won’t get hot. I’ve replace the filters and water and no heat. Is the heating element the problem if so can I change it??? I am mechinally inclined.

    • Hi Roberto. If the filter trick didn’t work, it’s possible your heater element is bad, but without testing it ourselves and checking other potential issues it’s impossible for us to say for sure.

      Your best bet would be to get a hot tub technician out to your spa. If you’re in the Philadelphia region give us a call: (215) 491-7446 x111
      Thanks

    What is the cost difference having the temp set at 80 than 100 during the winter months? Is it $5.00 more? Thinking of ways that I can save on electric when the tub is not in use during the winter months in Michigan
