From time to time, hot tub spas need repairs to replace worn or defective parts.  Most problems have several possible causes, hence several possible solutions. 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

Test equipment for troubleshooting hot tub spa systems 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.

"It's just like the name says.  Actually easier to install the new spa pack than I thought it would be.  I appreciated the expert tech support you provided by phone, the new pack arrived promptly, and my spa is up and running again just like new.  Can't thank you enough for the great service and fair prices too."
