  • Page 25 XII. TROUBLESHOOTING STEPS NOTE: The symbol “ ” prefixing the measured value denotes “approximate”. Most measurements will not be completely accurate with the values represented in this manual, but the SCA will function normally. Usually, measurements that are extremely different from the indicated measurements will represent a possible failure in the component.
  • Page 26 A. Pump Troubleshooting Symptom Pump Not Starting, Pump Starting but has Low Circulation Theory: The Water Pump uses a 230 VAC motor that circulates the water from the intake at the bottom of the Pump out through the Nozzle using an impeller attached to the Motor Shaft. The Run Capacitor gives the Pump an initial punch to rotate the Pump Motor Shaft in the proper direction as well as supply half the voltage to the Pump.
  • Page 27 Unplug the SCA from power and reseat (unplug and plug back in) the J6 “CONTROLLER” ribbon cable (See Figure 20). The latch must be released to remove the ribbon cable. Press the latch with a thumbnail and wiggle the connector out of the slot. Plug the ribbon connector back into the PCB slot and ensure it snaps securely.
  • Page 28 2. Check the Pump Motor Resistance Unplug the SCA from power and remove the “PUMP” connector from the PCB. Choose the Resistance Selection Ω on the multimeter. Check the resistance of the Pump between pins 1 and 3 (See Figure 22). If the multimeter reads ~ Ω, continue to the next step (Step b).
  • Page 29 3. Test the Input Voltage to the Pump a. With the SCA still unplugged from power and the “PUMP” disconnected from the PCB, place one lead of the multimeter Test Hooks to pin 1 and the other Test Hook to pin 3 on the PCB connector. Set the multimeter to the AC Voltage Selection .
  • Page 30 If there is no voltage between pins 1 and 3 and pins 2 and 4 and the “PUMP ON” LED is lit, replace the PCB. d. If there is voltage between pins 1 and 3, and no voltage between pins 2 and 4, the Run Capacitor may be defective.
  • Page 31 Rotate the Pump Shaft (See Figure 28). The shaft should rotate extremely easily and smoothly by rolling a finger across it. There should be no stiffness, rough spots or binds. If there is stiffness or it feels bound, inspect around the Impeller for any obvious buildup that can bind up the Impeller. To thoroughly inspect for any build up around the Impeller, the Manifold Plate can be removed (seven screws).
  • Page 32 B. Heater Troubleshooting Symptom Not Heating, Not Reaching the Set Temperature, EO Over Temperature Error Theory: The Heating Elements have an internal resistance that create heat when current flows through. When submerged in water, the heat is transferred to the water. It should take approximately 3 minutes per degree to heat up the bath.
  • Page 33 d. Unplug the SCA from power and reseat (unplug and plug back in) the J6 “CONTROLLER” ribbon cable (See Figure 30). The latch must be released to remove the ribbon cable. Press the latch with a thumbnail and wiggle the connector out of the slot. Plug the ribbon connector back into the PCB slot and ensure it snaps securely. Power on the SCA and press the Start Button If the “HEATER ON”...
  • Page 34 2. Heater Element Resistance Test If the “HEATER ON” LED is lit, and the SCA is not heating up properly or not at all, unplug power from the SCA. b. Remove the “Heater Element 1” Connector. Set the multimeter to the Resistance Selection Ω. Measure the resistance across the outside wires of the Heater 1 Connector (See Figure 32).
  • Page 35 C. Temperature Sensor Troubleshooting Symptom Not Heating, Inconsistent Heating, Not Reaching the Set Temperature, Over Heating r1 Error Theory: The Temperature Sensor changes resistance according to the temperature of the water. As the temperature increases, the resistance of the sensor decreases. The Control Panel uses this resistance to determine the temperature of the bath.
  • Page 36 Steps: 1. Reseat the Connectors Unplug the SCA from power and remove the Back Panel (See How to Remove the Back Panel Section III A). b. Reseat (unplug and plug back in) the NTC Connector on the PCB. The NTC Connector has a latch that must be depressed to unlock the connector from the slot.
  • Page 37 3. Check the resistance at 50°C A thermometer with a Celsius selection can be used to determine whether the temperature of the bath is displayed correctly on the Control Panel. Set the SCA to 50°C and press the Start Button .
  • Page 38 D. Water Level Sensor Troubleshooting Symptom High or Low Water LED Flashing on the Control Panel, r2, r3 Error Theory: The Water Level Sensor uses two internal switches within a hollow rod straddled by a watertight stainless-steel float that slides along the rod as the water level changes. If the water level is at the minimum or maximum level, the magnetic property of the float closes an internal switch, which generates an error.
  • Page 39 2. Check the resistance of the Water Level Sensor Remove the sensor from the Motor Tray (See Sensor Assembly Replacement Section V). b. Visually inspect the Water Level Sensor Assembly. If there is a buildup on the shaft that inhibits the free up and down motion of the float, clean off the buildup.
  • Page 40 E. No Power to SCA Troubleshooting Symptom SCA Appears to have no Power Theory: The SCA 3600 requires 230VAC +/- 10% single phase power. The acceptable voltages for this SCA are 207 VAC → 253 VAC. The U.S. generally uses 208 VAC, but a voltage of 220 VAC is not uncommon. The EU generally uses a voltage of 230 VAC.
  • Page 41 b. Set the multimeter to the AC Voltage Selection and check the voltage at the building’s outlet between the Y and X sockets (North America) or the N and L socket (Europe) (See Figure 44). If the multimeter reads ~ VAC (NA) or ~ VAC (EU), ensure the power cord is securely inserted into the outlet and check for voltage at the female end of the power cord (between the two top slots).
  • Page 42 d. Unplug the SCA from power and reseat the J6 Control Panel ribbon cable. Press the latch with a thumbnail (See Figure 46) and wiggle the connector out of the slot. Press the connector firmly back into the slot and ensure it snaps in securely.
  • Page 43 d. Unplug the SCA from power. Set the multimeter to Diode Test Mode Check the continuity of fuses FB1 and FB2 (See Figure 48). If the multimeter reads ~ , the fuses are good, replace the PCB. If the multimeter reads , replace the fuse.
  • Page 44 b. The TCO can trip (open) if the temperature of the bath exceeds 90°C. This removes all incoming power to the PCB. Press the red square button in the middle of the TCO (ensure the SCA is unplugged from power and the temperature of the bath is less than 80°C).
  • Page 45 d. Insert one multimeter lead into the wire terminal connected to the input of fuse F1 and touch the other lead to the left prong of the PEM. Toggle the power switch to the “On” position (left). • If the multimeter reads (continuous), continue to the next step.
