October is a useful time to decide what you would do if your hot tub lost power on a freezing night. A storm may interrupt electricity throughout the neighborhood, or the spa may stop heating while everything inside the house works normally.
You don’t need to become a repair technician to prepare. Start with your owner’s manual, a well-fitting cover, and a plan for getting help. These steps can make it easier to respond promptly without guessing about your equipment.
Before freezing weather: make a simple outage plan
Find the manual for your spa’s exact model and year. Hot Spring’s owner’s resources include separate collections and model-year manuals. Save yours where you can read it even if your internet connection is unavailable.
Keep the following information together:
- Spa model and year, plus the serial number if already recorded
- Your service provider’s phone number
- Your normal temperature setting and maintenance routine
- Instructions for anyone checking the spa while you’re away
Use fall to address maintenance you have been postponing. Clean filters according to the manufacturer’s directions and inspect the cover for cracks, sagging, and gaps around the seal. Hot Spring identifies cover condition and a tight seal as important parts of cold-weather care. A damaged cover is worth discussing with your dealer before winter. Hot Spring maintenance guidance
If a routine water change is due, plan it before freezing weather and follow the model’s refill procedure. Hot Spring recommends completing needed drain-and-refill maintenance before temperatures fall below freezing. Winter-use guidance
If power goes out: keep the cover closed
Keep the insulated cover in place and secured. Avoid repeatedly lifting it to see whether the water still feels warm. Opening the cover releases heat; Jacuzzi’s outage guidance specifically recommends leaving it closed to conserve warmth. Manufacturer outage advice
Check your utility’s outage information from a safe location. Note when you first discovered the problem and any available restoration estimate. Those details will be useful when you speak with a spa professional.
Contact your dealer promptly if temperatures are below freezing and power or normal circulation has stopped. Ask what your particular spa needs under the current conditions, including whether professional winterization should be arranged.
How long can a hot tub stay without power?
A generic number of hours or days is not a reliable plan for your spa. Its condition, insulation, cover, starting water temperature, and exposure all matter. Avoid treating someone else’s outage experience as a guarantee for your backyard.
Warm water in the main tub also does not prove that every component is protected. The 2026 Hot Spring Highlife manual warns that extreme cold combined with wind can cause partial freezing of the jet pump even while the main water remains at its selected temperature. It also cautions that lowering the temperature setting increases freezing risk during an outage or malfunction when outdoor temperatures are below freezing. Highlife owner’s manual, printed page 30
The practical takeaway: get advice for your model early, rather than waiting for visible ice.
If the house has power but the spa is not heating
A lit control panel or working massage jets do not establish that the heater and circulation system are operating correctly. Hot Spring’s troubleshooting guide lists several possible causes for a spa that will not heat, including circulation problems.
Record any error message or blinking indicator and tell your service provider whether the temperature is falling. Follow only the checks specifically allowed in your owner’s manual. A GFCI that will not reset, recurring trips, or a heating problem that persists calls for professional attention. Hot Spring troubleshooting guide
Do not open the electrical control box, bypass a safety device, or improvise an extension-cord connection. Hot Spring’s Highlife manual prohibits extension cords and says the control box has no user-serviceable parts. Electrical work belongs with a qualified professional.

Don’t confuse draining with winterizing
Opening the drain does not necessarily remove water from the spa’s plumbing and equipment. Freeflow’s 2026 manual explains that winterization requires removing water from internal lines, where remaining water can freeze and cause damage. It also warns that plumbing or equipment can freeze during draining in extremely cold conditions. Freeflow owner’s manual, printed page 20
Before draining a nonworking spa in freezing weather, contact your dealer for a model-specific plan. If shutdown is needed, arrange complete winterization. Avoid turning a stressful outage into an incomplete do-it-yourself shutdown.
When the power returns
If you see ice, a new leak, or signs of damage, leave the spa unused and ask a technician for instructions before trying to restart it. Otherwise, check that normal heating and circulation resume, following the manual. Report persistent errors or abnormal operation to your service provider.
Before using the hot tub again, test the water and restore the sanitizer and pH to the ranges required for your spa and water-care system. Follow product labels and manufacturer directions for any treatment. The return of electricity alone does not establish that the water is ready for soaking. Post-outage water-care guidance
