Page 5: Standard Troubleshooting Approach (S.t.a.)
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 ser- vice industry has made it difficult to raise the price of a service contract; or charge more for time and materials than the competitive shop down the street. -
Page 6: Satisfying The Customer
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. -

• The customer loses use of the hot tub. You lose money because you must go back to make it right. Jacuzzi loses its reputation for quality. 2.2 Avoiding E.S.D. Damage We can’t prevent static charges from building up within our bodies as we go about our jobs, so we must do three things to protect circuit boards from getting zapped: 1. -

Page 33: Weak Or Surging Jets
8.10 Weak or Surging Jets Weak or surging jets are usually caused by an insufficient water supply to the pump or a clogged or broken pump impeller. The water level may simply be low, or there may be an obstruction in the water flow path to the pump or in the pump’s impeller. Before making a service call, ask customer to verify all jets are open. -
Page 34: Jets Pump Runs And Quits During Jet Mode
8.11 Jets Pump Runs and Quits During Jet Mode This is usually a problem of pump overheating. The pump motor incorporates a thermal cutout switch that triggers when the motor gets too hot. There is no reset for this condi- tion. -
Page 35: Circulation Pump Not Working
8.12 Circulation Pump Not Working The circulation pump works as follows: • 2014+ J335/J345/J355/J365/J375/J385 circ pump runs 8 hrs (default) • 2014+ J315/J325 24 hrs (default) Note: See Service Bulletin page 33 The circulation pump should be running unless “summer logic” is activated. Verify “summer logic” is not activated before starting. -
Page 36: Troubleshooting A Thermal Pump Cutout
8.13 Troubleshooting A Thermal Pump Cutout 1. Verify voltage to hot tub is 240 VAC ±10% (or 120 VAC ±10% for convertible models). An insufficient voltage supply can cause the motor to pull too much current and overheat. The situation must be corrected. 2. -
Page 37: Service Bulletin: 2014 J-300 Summer Logic Upgrade (July 29, 2014)
8.15 SERVICE BULLETIN: 2014 J-300 Summer Logic Upgrade (July 29, 2014) We have recently discovered a glitch in the summer logic code of the 2014 J-300 software. The issue will result in the circulation pump turning off and on repeatedly at the summer logic threshold. For example, if the spa is set for 100°F and reaches 102°F (two degrees above the set temp), the pump will cycle off and on as long as the primary cycle is engaged and water temperature remains two degrees above the set temp. -

Page 41: A1 Checking Voltage To Hot Tub
Checking Voltage to Hot Tub Correct supply voltage wiring to the hot tub is essential for safe/proper operation. The first step in troubleshooting a new installation should be to take voltage readings at the terminal block TB1. Do not trust wire colors. Electricians make mistakes and electrons are color-blind. A low line voltage or incorrectly wired hot tub will result in either of the following symptoms: A) Strange or intermittent symptoms, B) Displays with indications that simply cannot be correct Many of the most perplexing problems in the past have been wiring errors and voltage drop prob-... -
Page 42: A2 Checking Current Consumption Of Devices
Verify All 240 VAC Models power connections are as follows: North American 240 VAC/60 Hz, Fig. D: • Hot to Hot: Measure across test points 1 and 2 for 240 VAC. • Hot to Ground: Measure across test points 1 and 23 for 120 VAC; then across 2 and 23 for 120 VAC. -
Page 43: A3 Checking Voltages To Devices
Checking Voltages to Devices Device voltages are often measured at the circuit board to determine whether the board or device is bad. If the circuit board delivers voltage when device operation is called, the circuit board is prob- ably good and the problem lies with the device or the wiring to the device. The following voltage chart shows operating voltages for all major hot tub components. -
Page 44: A4 Testing Flow Switch
Testing Flow Switch When the “FL1 or FL2” message appears, it means the flow switch contacts have failed to close when the pump was turned on, or failed to open when the pump was turned off. This could be caused by an excessively dirty filter, an obstruction in the flow path or by a bad switch. -
Page 45: A6 The Watchdog
The Watchdog “- - -” Three horizontal dashes with no other control panel indicators illuminated is a result of the watchdog circuitry detecting a potential destructive condition within the hot tub. There are many conditions that can cause a watchdog error message. Except for a runaway heat condition, most are caused by a faulty circuit board, bad hi-limit sensor, or temperature sensor. -
Page 46: A8 Understanding Ph
Understanding pH Keeping hot tub water clean and clear involves a very complex set of chemical reactions. Most impor- tantly, the hot tub must be sanitized. Bacteria, algae, and other single-cell life forms that may find their way into the hot tub must be killed. Three chemical elements, chlorine, bromine, and ozone are all good sanitizing agents. -
