Is Your Hot Tub Getting Too Hot?

Hot tubs are made to create and retain heat, but sometimes in the summer, your spa can do that heating thing a little too well. If you’re worried about your hot tub getting too hot, there are some things you can do to prevent it and even correct it once it’s started.

How to Prevent Overheating

Did you know that running your hot tub’s filtration mode for extended periods of time when temperatures exceed 100 degrees could cause your hot tub to overheat, or even shut down altogether? How can you fix this? It’s easy! Just adjust your filtration settings!

  • Check to see if your spa is in filtration mode
  • Run your filter overnight or during the coolest hours of the day
  • Have your filter running for at least 1 hour
  • Take the cover off periodically to allow heat to escape
  • Once summer is over, don’t forget to readjust your filtration settings

Other Causes 

Do you have your filtration set for summer weather, but it’s still overheating? It could be because the water isn’t flowing through the heater fast enough. This is usually caused by:

  • Dirty filter cartridge
  • Closed or partially closed jets or valves
  • An air lock in the pump
  • Low water level
  • Blocked pipe or drain cover

Bonus Summer Maintenance Tips

Do you close your hot tub for the summer? That’s okay! But you still need to check on it every two to three weeks and perform maintenance. This will keep your hot tub in tip-top shape and ensure it’s ready to go when you want to open it back up. Another thing you may want to consider doing during the summer is treating your cabinet and cover with some UV protection.
