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.
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 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.
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! •...
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.
C) lay the replacement board on the ground, D) place the bad board in the bag from which you removed the re- placement board, E) return bad board(s) to Jacuzzi Premium in undamaged sealed static protective bags.

4.0 Main Control Panel Functions Panel Functions: Heat Indicator: Lit when heater is on. Warmer Button: Increases water tempera- ture setpoint. Cooler Button: Decreases water tempera- ture setpoint. LED Display: Can display current water temperature (default display*), water tem- perature setpoint, selected fi ltration mode, and error messages.
Page 21
Standard Filtration Modes FØ - F3 Heating in either of these modes (FØ - F3) is automatically controlled by the water temperature. If the hot tub water drops 2ºF (1.2ºC) below the temperature setpoint, the heater will turn on with the circula- tion pump.
4.3 Aftermarket Ozone Facts An aftermarket ozonator can be installed on all 2002+ models. A mazzei injector is required on all mod- els. Ozone System Specifi cations • Circulation pump runs 24 hours • Ozonator runs 24 hours • The ozonator shuts off when a Jets Button is pressed. The ozonator will resume operation approxi- mately 5 minutes after the jets are turned off intentionally or automatically.
5.5 Lock Out Mode The control panel temperature display fl ashes when the Lock Out Mode is active. Lock Out Mode disables all hot tub functions to permit fi lter cleaning. If the hot tub is heating when lockout mode is selected, the heater will immediately turn off and the circulation pump will cycle water for 30 seconds to cool the heater element, then turn off.
7.0 Troubleshooting Using The Control Panel 7.1 Control Panel Displays Complete operating instructions for the control panel can be found in the owner’s manual. The hot tub’s self-diagnostic control system constantly monitors the hot tub for proper operation. When anything goes wrong, the control panel displays a message for the user which may result in a service call.
FL1 And FL2 Water Flow Problem • FL1: The fl ow switch is not closed when the circulation pump is running. The heater is deactivated. Proper water fl ow is inhibited or the fl ow switch may be obstructed, misaligned or defective.
Plug in a new control panel. If the problem is corrected, replace the control panel. If the problem persists, proceed to step 3. Check the voltage at the transformer secondary. See section A15, page 57, for transformer testing instructions. If the voltage is bad, replace the transformer. If the voltage is good, proceed to step 4. Check the circuit board transformer connections.
8.0 Troubleshooting Without The Control Panel • Diagnostic Tools for Sections 8.1A - 8.1D: Clamp-on ammeter, voltmeter and ohmmeter. • Suggested Spare Parts for Sections 8.1A - 8.1D: Circuit board, control panel, temperature sensor, fl ow switch, heater assembly, hi-limit, circulation pump. Refer to page 59 for additional information. 8.1A No Heat Or Not Enough Heat •...
Page 28
8.1B No Heat Or Not Enough Heat • Symptoms: Circulation pump (heating pump) not turning, panel heat indicator not lit, panel is fl ashing FL2. Standard Troubleshooting Approach Pull wire off flow switch. Does the FL2 error message go away? Turn off power to hot tub.
Page 29
8.1C No Heat Or Not Enough Heat • Symptoms: Circulation pump (heating pump) not turning, panel heat indicator not lit, panel is fl ashing FL1. Standard Troubleshooting Approach Is there correct voltage coming to the hot tub at TB1? 240 VAC, +/-10%, or (120/240 VAC, +/-10% for J315/J325 models).
Page 30
8.1D No Heat Or Not Enough Heat • Symptoms: Circulation pump (heating pump) is turning, panel heat indicator not lit, panel is fl ashing FL1. Standard Troubleshooting Approach Is the circulation pump (Heat Pump) moving water? Verify hot tub is in standard filtration mode (page 21).
Page 31
(page 21). Set temperature high enough to initiate a heat call. Remove power to hot tub then plug in a spare control panel. Turn power on. Does indicator work now? Replace control panel. Call Jacuzzi Premium Technical Support.
Explain what you will do if the problem returns. Check back with the customer in a few days if you haven’t been contacted. If the customer calls back, call Jacuzzi Premium Technical Support. Note: All models use a ‘magnetic reed switch” type of fl ow switch that can remain closed or open from debris interference.
8.3 Nothing Works Things to remember: when a system fails, there is probably one, and only one problem. Verify power to the hot tub by observing the control panel’s LED display. The control panel will usually display some- thing as long as there is proper power to the hot tub. Check for error messages. Displayed error mes- sages usually indicate the problem.
8.5 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.

• If a component has excessive amperage draw, replace that component. If you should need to contact Jacuzzi Premium Technical Support, these are questions that will be asked of you. It is also a good idea to have the “Troubleshooting Data Collection Form” (see example...
North American 60Hz Installations: As of January 1, 1994, the National Electrical Code (NEC) requires a Ground Fault Circuit In- terrupter (GFCI) on all hot tub installations in the US. A GFCI must be wired correctly or it will trip. Make sure the electrician has wired the GFCI according to the diagrams on page 52. 8.6 Hot Tub Light Will Not Come On Diagnostic Tools: Voltmeter.
8.7 No Jets This is a condition of constant zero water pressure. The fi rst step in diagnosing the problem is to determine if the pump is actually turning. Once this determination is made, follow the appropriate portion of this S.T.A. Diagnostic Tools: Voltmeter, spare control panel.
Remove debris or loose foreign object. If pump suction line is clear, check for blockage in plumbing on the return side of pump. Call Jacuzzi Premium Technical Support for assistance in performing this verification step.
240 VAC the pump drawing –10 % (or 120 VAC too much current. –10% for J315, J325 Contact Jacuzzi models) at test Premium Technical points 1 and 2. Support. Replace pump. Danger: Electrical Shock Hazard Exists! High Voltage Present On Circuit Board.
8.10 Circulation Pump Not Working The circulation pump should be on for the programmed duration each day and for a heat call unless “Summer Logic” is activated. Verify the pump should be on before trouble- shooting. Check the circulation pump start time and duration setting. Refer to section 5.6C (page 23).
One is to change the fi lter cycle periods so that they do not coincide with the hottest time of the day and peak power consumption hours. Another is to ventilate the equipment bay. Call Jacuzzi Premium Technical Support for advice on this matter.
8.13 Ozone not working Diagnostic Tools: Clamp-on ammeter and voltmeter. Suggested Spare Parts (Page 59): Ozonator, circuit board, control panel. Standard Troubleshooting Approach Turn power to hot tub off and on. Wait approximately two minutes for filter cycle to begin and turn on ozonator and circulation pump.
A1.0 Checking Voltage To Hot Tub Correct supply voltage wiring to the hot tub is essential for safe/proper operation. The fi rst step in troubleshooting a new installation should be to take voltage readings at the terminal block TB1. Do not trust wire colors.
A2.0 Checking Voltages To Devices Device voltages are often measured at the circuit board to determine whether the board or the device is bad. If the circuit board delivers voltage when the device operation is called, the circuit board is prob- ably good and the problem lies with the device or the wiring to the device.
A4.0 Testing The Flow Switch When the “FL1” or “FL2” message appears, it means the fl ow switch contacts have failed to close when the circulation pump was on, or failed to open when the circulation pump was off. This could be caused by an obstruction in the fl ow path or by a bad switch. The fi rst thing to look for is an obvious obstruction, remembering (while not likely) that it is possible for a small object to work its way into the plumbing where it will not be obvious.
“fresh-as-all-outdoors” smell. Jacuzzi Premium offers a type of ozone system, the corona discharge (CD). The corona dis- charge (CD) uses a highly effi cient low current/high voltage arching chamber to generate ozone. The CD ozone introduces ozone into the hot tub water through a “Mazzei”...
