ACTION TO BE TAKEN
1.a. Push the control "OFF".
b.Open the drain valve allowing tank to drain completely.
c.Close the drain valve.
d.Push the control "ON".
e.Unit will begin filling, listen for a click noise. Within 20 seconds after click noise is heard, the water fill will shut off. This will indicate the tank is full. Go to step 3, if the tank does not fill - See SYMPTOMS: "Unit won'tfill up".
2.If the tank filled but the relay click was not heard, temporarily ground the two long probes. If the click is heard as each probe is grounded, replace the level probe. If the click is not heard replace the "PCA" printed circuit assembly.
3.After it has been determined that the tank has filled and the click noise was heard, remove the heating element access panel. Using a voltmeter, check the voltage between the two wires on each heating element - the voltage should be 208V/240V. If proper voltage is found call the factory for replacment heating elements. If no voltage is found - check wiring diagram - call Service Deparment.
1.Check that the sensor cable is connected to J4 on the "PCA" printed circuit assembly.
2.Check the cable connection to the temperature sensor.
3.Replace sensor and/or cable - call Service Department.
1.Check sensor cable for damage from nail/staple puncture.
2.Check sensor cable ends for frayed/exposed wire strands.
3.Replace sensor and/or cable - call Service Department.
1.Check that the control cable is properly plugged in at the control and at the generator. Digital Control to primary SK3 connector on the PCA. Turn off power supply, wait one (1) minute then turn back on. Check for proper operation. If "E003" is still displayed turn off power supply, remove control cable and plug into secondary SK4 connector. Turn on power supply and check for proper operation. If "E003" is still displayed turn off power and call Service Department.
1.If bath is too hot, shut off circuit breaker and call Service Department.
2.Treat as "E002" fault above.
1.Check that the control cable is properly plugged in at the control and at the generator. Connect Control to primary SK1 connector on the PCA. Turn off power supply, wait one (1) minute then turn back on. Check for proper operation. If "STEAM" is still "blinking", turn off power supply and call Service Department.
2.Check sensor/cable as with Digital "E001" and "E002"
3.Replace Control - call Service Department.
1.Replace the control - call Service Department.
1.Turn off the power to the generator, replace printed circuit assembly - call Service Department.
1.Flush tank 3 times. See section 8, flushing procedure.
2.Call Service Department.
1.Replace control - call Service Department.
2.Replace PCA - call Service Department.
