1.0 Standard Troubleshooting Approach (S.T.A.) 1.1 Why A Standard Troubleshooting Approach? Service prices are basically set by local industry and geographic region. Stiff competition in the service industry has made it diffi cult to raise the price of a service contract; or charge more for time and mate- rials than the competetive shop down the street. If your business is to be profi table, you must control the overall cost of service. The total cost of service is made up of many individual f

4. Question the homeowner to determine, if possible, what specifi c 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’s manuals in an accessible place. • Know the difference between the spa’s components and how they perform when utilized in the spa. Example: An air control will induce air into the plumbing of the jet, increase the fl ow

8. 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. 9. Use the home service visit as an opportunity to sell aftermarket items such as chemicals, towels, etc. 10.

1.5 Preparing For A Service Call 1. Know what each call is asking of you; determine whether or not the extent of service can be han- dled 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. • If you plan to charge the customer for travel expenses, make sure that they are aware of the costs before you show up. 2. Make sure all of your

9. Make professional repairs. • Putting bondo, underwater epoxy, silicone or any other product to fi x cracked or leaking plumbing will not adequately correct the problem and will most likely result in a return visit. Replace the com- ponent or come back and do it for free! • Make repairs look as good as or better then when you started. 10. Make sure you leave the customer’s home as clean as you found it. • Most customers don’t mind if you are having lunch in their backyard, as l

1.8 Satisfying The Customer Most customers do not care what work you have done or what parts you have replaced, 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. Show them the bad part(s) and explain or show why it is bad. • Develop the habit of examining the hot tub’s you service. Compliment customers on the things they are doing right. Tell them how their care and

Static electricity is always being generated around us, even at those times when we no longer get zapped after walking across a rug and touching some- thing. Like all state-of-the-art circuit boards, the hot tub’s circuit board can be dam- aged by unnoticed static electricity. Damaged is the key word. Sometimes a board which has been subjected to ESD will fail immediately upon being p
