    Parts Usage - Except in rare circumstances, only one part fails. How many parts do you replace before you find the bad one. The Jacuzzi Hot Tubs S.T.A Manual has been designed to help you control the overall cost of service by focusing on the three important aspects of your job outlined above. The S.T.A will help you fix your customer’...
  • Page 6 Question the homeowner to determine, if possible, what specific component is not functioning. • Use the map of the spa (see below); become familiar with the components and their names. This will also help when speaking to technical service. • Keep the Owner’...
  • Page 7 Make Sure there is access to the main breaker and GFCI, and ask the homeowner to disconnect if possible before you arrive at their home. Use the home service visit as an opportunity to sell aftermarket items such as chemicals, towels, etc. 10.

  • Page 8: Preparing For A Service Call

    1.5 Preparing For A Service Call Know what each call is asking of you; determine whether or not the extent of service can be handled with a simple phone call or if it requires a visit. • Determine whether the call is warranty or non warranty. Make sure the customer is aware that the manufacturer will not cover out-of-warranty service.

  • Page 9: Before Calling Technical Support

    Make professional repairs. • Putting bondo, underwater epoxy, silicone or any other product to fix cracked or leaking plumb- ing will not adequately correct the problem and will most likely result in a return visit. Replace the component or come back and do it for free! •...
  • Page 10 1. Satisfying The Customer Most customers do not care what work you have done or what parts you have re- placed, but they always care whether or not their problem goes away. When you are done, show them that their problem is gone. If they ask how you did it, take a few minutes to explain.

    If the hot tub runs only a few months, the customer thinks the circuit board was a low quality product. • The customer loses use of the hot tub. You lose money because you must go back to make it right. Jacuzzi Hot Tubs loses its reputation for quality.

    Check the voltage at the transformer secondary. See section A15, page 57, for transformer testing instruc- tions. If the voltage is bad, replace the transformer. If the voltage is good, proceed to step 4. Check the circuit board transformer connections. If the connections are loose or oxidized, repair the connec- tions and retest the system.

  • Page 34: House Breaker Trips

    .5 House Breaker Trips The hot tub’ s current draw will vary depending on how it’ s circuit board is jumpered. Jumper options determine whether multiple functions can operate together. If the house breaker trips, check the hot tub’ s current draw. If the jumpers are properly set and the current draw is within expected limits, the house breaker or wiring may be defective and need to be replaced or repaired.
