Sometimes a clogged filter will restrict the water from flowing at the proper pressure, which can prevent your heater from turning on. The first action for a no-heat situation is to turn off the tub, remove your filter, turn on the tub and see if your heater will come on. (You can’t just remove the filter, you have to power off the tub to reset the computer.)
If the heater comes on, you have a dirty filter and cleaning or replacing it should take care of your problem. But don’t run your hot tub too long without a filter.
If your heater still won’t come on, call us to arrange a visit. Unfortunately, we are limited in what we can do during the winter. If the ground is snow covered or your tub is situated in a way that we can’t easily access your electronics – such as inside a deck or against a wall – we may have to drain and winterize it and put off your heater repair until the spring. Do not just drain the water from your tub and assume the tub is empty. 99 out of 100 times, there will be up to 10 gallons of water hidden in pipes and pumps, which will freeze, expand, and can cause up to thousands of dollars in damage.
