Thawing & Restarting a Frozen Hot Tub
"...Due to a power outage while away my tub was completely frozen solid.
During the recent thaw I have removed the ice and there is (no) water draining out the hose. However even when I flip the circuit breaker back on there is no power to the tub. Is there a switch or something that has been tripped inside that needs to be reset? I have the panels off and I don't see any leakage etc.
I'm hoping this can be repaired, as the tub is only 3 yrs old."
Check for fuses on the electrical panel inside the hot tub if you cannot find a reset button. Although each manufacturer uses different components, you will find that either a reset was tripped or a fuse was blown if the power came back on when everything was frozen.
Be certain that everything has completely thawed before you re-apply power, because it will only blow the fuse again if there is still ice inside the pump(s).
Also, you must be very lucky if there is no water leakage. Typically, PVC plastic pipes will crack, although flex hoses will usually survive a freeze. The pump(s) should also survive, but the junctions to the hoses may crack, and you need to make sure they are undamaged before completely filling your tub again.
P.S. I always try to post answers here in this blog so that others can also benefit from reading your questions. So, if you send me an email, please be patient because it sometimes takes a few days for me to get the answer posted. Although I always try to reply promptly, if you have an urgent issue, you should contact your manufacturer or dealer for immediate help.
