My hot tub is not heating
If your hot tub is not heating and is cooling down there are a few things you can do yourself to troubleshoot the problem with your spa. If the heat indicator led is not lit, check the temperature setting as some spas will default to a factory setting such as 95°F or 100°F after a power outage, also check for energy saving settings such as economy or sleep mode which could be inadvertently set by pressing certain keypad strokes and cause a drop in temperature. Then check for any error codes on the keypad such as flo , fl or 3 dots flashing. If any of these error codes appear they mean that there is a problem with the flow of water through the heater manifold. One of the most common causes of poor flow is a blocked or dirty filter. The first thing to try is to shut off the gfci breaker to turn the power off to the hot tub and then remove the filter cartridge(s). Leave the filter cartridges out, check that there is nothing in the spa water which could be drawn into the open suction intake and turn the gfci breaker back on. This action will reset any error codes which were displayed on the topside control and start the sensor checking process over again. Now observe the topside display, if the error code does not return and the heat indicator led lights up then the flow issue has been eliminated and the filter cartridge must be dirty and blocking the flow. Clean the filter and reinstall it. If the spa continues to heat and operate properly you have solved the problem. If the led goes out and the error code is again displayed on the topside control then you need a new filter cartridge.
If the no heat problem is not caused by a dirty or worn out filter cartridge then check to see if the circulating pump is running. If it is not running but just humming then the pump will need to be serviced. Average cost of overhauling a spa pump is around $140, a new 2 speed spa pump will cost in the neighbourhood of $450 to $800 depending on the size and model. If it doesn’t make any sound then troubleshooting the spa pak controls will be necessary. That is beyond the scope of this article and most hot tub owners and DIY’ers and should be done by a qualified service technician.
Another cause for a hot tub to stop heating is a faulty pressure switch. This is characterized by a flow error code such as flo, fl, or 3 dots flashing on the topside display. To check the pressure switch use a multimeter to confirm continuity through the pressure switch while the circulation pump is running. If there is no continuity then replace the pressure switch. Cost for a pressure switch varies from $25 to $50 depending on the model and style of switch.

PROTECTING YOUR SPA FROM DAMAGE DUE TO FREEZING
In the winter when temperatures drop below freezing it is a good habit to check your spa every day or two to make sure it is functioning properly. If you don’t want to go outside to check it then using a wireless digital thermometer with an indoor remote display will tell you if the temperature in the spa is dropping.
If the spa is not heating and there is an error message such as “ flo” ,”fl”, or 3 dots flashing on a digital keypad or the heat indicator light on older spas is won’t come on, then there is a blockage in the water flow. Try removing the filter cartridges, if this corrects the problem then clean or replace them. If this does not correct the problem then shut off power to the hot tub for 10 or 15 minutes then turn back on. If this corrects the problem continue to watch the spa closely to make sure it doesn’t happen again. If it doesn’t clear the error then call Pro-Tech Pool and Spa Service for an appointment for a service call. Put a small heater under the cabinet in the equipment area to prevent freeze damage.
