    XIII. 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: Pump And Transformer Troubleshooting

    A. Pump and Transformer Troubleshooting Symptom Pump Inoperable, EP Error, Blowing F2 Fuse, Inverter Error, Low Circulation Theory: The Water Pump uses a 115VAC 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 Transformer is used to isolate the Pump from the rest of the circuitry and to reduce Electro Magnetic Interference (EMI).
  • Page 27 Figure 24 – Pump Screen and Nozzle 3. Reseat the Connectors a. Reseat the connectors (See How to Reseat the Cable Connectors Section XII). 4. Measure Pump Motor Resistance a. Ensure the SCA is unplugged from power. Remove the connector for the Pump from the “PUMP IN” pins on the PCB and measure the resistance of the Pump using the .7mm Test Probes.
  • Page 28 b. Check the resistance of the Pump between the wires on pins 2 & 4 on the cable connector (See Figure 26). Ω Figure 26 – Water Pump Resistance Measurement (pins 2 and 4) If the Multimeter reads ~ Ω, continue to the next section (Section 5). If the Multimeter reads Ω...
  • Page 29 Ω Figure 28 – Transformer Resistance Measurement (black wires) If the Multimeter reads ~ Ω, continue to the next section (Section 6). If the Multimeter reads Ω or , replace the Transformer. Verify initial measurement. 6. Check the Mechanical Rotation of the Pump Motor Shaft a.
  • Page 30 7. Quick Check the Run Capacitor a. With all connectors plugged in and the SCA powered up, press the Start Button . Roll a finger across the Pump Motor Shaft as in the previous test to rotate the shaft. If the Pump Motor starts up, this is an indicator that the Run Capacitor is defective.
  • Page 31 Warning High Voltage May Be Present on These Pins! Only qualified personnel should attempt this measurement Figure 31 – Pump Output Voltage (pins 1 and 3) c. Measure the AC Voltage across pins 2 & 4 (See Figure 32). If the Multimeter reads ~ VAC (~ VAC EU), the PCB, Transformer and Control Panel are operating correctly.
  • Page 32 10. Check the Transformer Input Voltage a. Set the Multimeter to the AC Voltage Selection . With the power unplugged, and the Transformer disconnected from the PCB, attach the Multimeter Test Hooks to pins 1 & 2 on the “TRAN” pins on the PCB (See Figure 33).

  • Page 33: Heating Element Troubleshooting

    B. Heating Element Troubleshooting Symptom: Not Heating, Over Heating, Under Heating Theory: The Heating Element has an internal resistance that creates 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 34 3. Check the Thermal Cutoff Switch (TCO) a. The Thermal Cutoff Switch, found on the back wall of the tank by the Main Power Switch, removes voltage from the Heater Relay if the temperature of the bath exceeds 90°C. If the switch is tripped (open), allow the temperature of the bath to drop below 80°C.
  • Page 35 4. Heater Element Resistance Test a. Unplug the SCA from power. b. Remove the top cover (See How to Remove the Top Cover Section III A). c. Set the Multimeter to the Resistance Selection Ω. Check the resistance of the Heating Element (See Figure 38). Ω...
  • Page 36 On 120V AC (US) Systems, if the Multimeter reads ~ VAC between H-N and H-L1, the Control Panel and the PCB are operating correctly. On 230V AC (EU) Systems, if the Multimeter reads ~ VAC between H-N and H-L2, the Control Panel and the PCB are operating correctly.

  • Page 37: Temperature Sensor Troubleshooting

    Connector C. Temperature Sensor Troubleshooting Symptom Not Heating at all, Over Heating, Under Heating, r1 Error Theory: The Temperature Sensor changes resistance according to the temperature of the bath. As the temperature increases, the resistance Temperature of the sensor decreases (See Figure 41). The Temperature Sensor Sensor resistance is evaluated by the Control Panel to regulate when power Connector...
  • Page 38 NTC Connector kΩ Figure 42 – NTC Connector @ 50°C 3. Set the SCA to 50°C and press the Start Button . When the bath heats up and the Control Panel displays 50°C, turn off the SCA and unplug the power cord. Unplug the NTC connector and measure the resistance across both wires.

  • Page 39: Water Level Sensor Troubleshooting

    Water Level Sensor D. Water Level Sensor Troubleshooting WLS-H Float WLS-L Connectors Symptom SCA beeping, High or Low Water LED flashing on 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.

  • Page 40: N Opower To Sca Troubleshooting

    E. No Power to SCA Troubleshooting Symptom SCA Appears to have no power, there are no audible clicks when toggling the power switch, the LED on the PCB is not lit. Theory: The SCA requires 110-120VAC (US) or 220-230VAC (Europe). The SCA chooses the correct configuration automatically according to the input power via an Evaluation Relay.
  • Page 41 ii. If the fuse does not blow, with the Transformer and Pump disconnected from the PCB, the PCB is probably still good. The Pump and associated components should be checked to determine which component is defective (See Pump and Transformer Troubleshooting Section XIII A). It is possible multiple components can be defective, so the entire Pump and Transformer Troubleshooting section should be checked.
  • Page 42 b. With the Power Cord plugged into the outlet measure the voltage at the female end of the Power Cord (See Figure 50). i. If voltage is present, continue to the next step (Step c). ii. If voltage is not present, check the continuity of the Power Cord and replace as needed. Figure 50 –...
  • Page 43 d. Unplug the power cord from the SCA. Set the Multimeter to the Diode Test Mode . Connect one probe of the Multimeter to the AC-L (red wire) terminal of the PEM and the other probe to the L male post (right prong) at the input receptacle (See Figure 52).

  • Page 44: N Opower To Display Troubleshooting Or Es Error

    F. No Power to Display Troubleshooting or ES Error Symptom : The SCA Control Panel appears to have no power and is not lit up when powering on the SCA. Upon plugging in to power and toggling the power switch, there are audible clicking sounds and the LED is lit on the PCB.
