From time to time, hot tub spas need repairs to replace worn or defective parts. This guide will help troubleshoot the malfunction using a logical progression of tests and observations, to isolate and identify the problem. CAUTION: Electrical repairs can be dangerous, especially around water. Repairs must be made by a qualified electrician or spa technician. Regardless of who performs the work, make certain that all electrical power to the hot tub or spa is disconnected prior to making any inspections or repairs. Shut the power off at the service panel, and as a secondary precaution, disconnect the power to the spa as well. Do not attempt to perform electrical repairs unless you are qualified. Useful Spa Repair & Diagnosis Tools The basic hand tools: screwdrivers, needle-nose pliers, wrenches, wire cutters, etc. are needed. Effective spa system electrical troubleshooting usually requires a multimeter for measuring voltage and resistance (ohms). A clamp-on amp meter is also very useful for diagnosing many electrical problems.
These meters can be acquired at most home centers. Spa does not run, no power, nothing works. Spa runs, but does not heat; No low speed pump; both speeds at once.trips at end of heat cycle.

Your hot tub relies on a circulating pump to keep the water moving throughout the circulation system. This pump draws water from the tub, pumps it through the strainer, filter and heater, then shoots it back into the tub through the jets. Many tub owners periodically drain and refill the tub. Failure of the tub’s pump to circulate water after a water change could be a symptom of several problems. Lost Prime Your pump may have an air lock in the housing and line that should be drawing water from the tub. Normally when the pump starts, the impeller drives the water already in the housing back into the tub, creating a vacuum in the housing that pulls more water from the tub through the suction line. If, during the process of draining the tub, you also drained the pump housing, the pump is said to have lost its prime and become airbound. Normally, the pump will reprime itself but sometimes there is too much air in the system and the repriming fails. Fixing Airbound Pump An airbound pump will run but not pump water.
The tub's control panel may show a "FLO" or "DRY" error. To fix this error, look for a marked air-bleed screw near the top or bottom of the pump housing. With the pump running, loosen the bleed screw until you hear air hissing out. Tighten it again when the hissing stops and you see water seeping out. Alternatively, run the pump and slightly loosen the large threaded ring securing the pump's output pipe to the pump housing until you hear air hissing out. When the hissing stops and water seeps out, tighten the ring again. Pump Problems The process of draining the tub might have coincidentally revealed problems with the pump and its lines. If the pump hums briefly and then shuts down, check for debris clogging the impeller or a broken impeller. Disconnect power to the pump. Access the impeller by undoing the screws holding the pump’s faceplate and pulling off the faceplate. The impeller will be right behind the faceplate. Remove any debris or replace a broken impeller. Also, check the suction line for leaks that admit air into the line.
Look for problems such as a broken pipe or a loose connection where the suction line joins the pump intake. Replace a broken pipe or tighten a loose connection. Check the Valves Some pump models call for users to close valves on the pump’s intake and outflow lines before draining the tub. The pump won’t work if you forget to open those valves before restarting the pump. And check that the jets of the pump are clear. Turning off the pump while you drain and refill the tub may have loosened debris from a deteriorated internal pump part and this may clog the jets. Also look at the leaf trap and water filter at the pump's intake line to make sure there is nothing clogging them. Power Trouble Be sure you have turned the power switch for the pump back on after you are done filling the tub. If the pump doesn’t come on, check that the circuit breaker or ground fault circuit interrupter for your pump hasn’t tripped off. If they have, flip the breaker back on. If the GFCI tripped, press the red “test” button to restore power.
