If your spa has lost power or is no longer heating it’s imperative you protect it from freezing until power is restored or a technician can repair the malfunction. The methods below can be used to help protect your spa against frozen/cracked pipes:
Do not drain your spa.
Step 1: Remove the front cabinet door (under your control panel.)

Step 2: Place a small space heater or 100W service incandescent light inside the cabinet to keep the pumps and pipes warm.
Make sure the heater is not somewhere where foam, wires or the shell will melt.
Step 3: Reinstall the cabinet door.
Step 4: Cover the equipment area with a heavy blanket for insulation. It is also important to leave the spa cover on and secured. This will help the water retain its heat until the spa is operational again.
Additional Freeze Protection Aid: Place a sump pump in the spa water so the water doesn’t sit stationary.
