Test 8
1. Find out if the unit was overloaded. If not, remove the belt from the
motor and spin the motor pulley. Does the motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the motor and measure the resistance of
the windings (pin 1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All readings
should be between 3 and 6 Ohms.
Test 9
1. Remove the belt from the motor and spin the motor pulley. Does the
motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the drive motor and measure the
resistance between pins 4 & 5 in the motor.
4. Disconnect the plug from the motor and measure the resistance of
the windings (pin 1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All readings
must be between 3 and 6 Ohms.
Test 10
Communication problem. Check the wiring between the main control
board and the motor control board.
Test 11
Communication problem. Check the wiring between the main control
board and the user interface board.
Test 12
Have the power company or professional check the frequency and
voltage of the incoming power under load.
Test 13
Check the resistance of the water NTC. Is it around 4.8K ohms?
Test 14
1. Check the resistance of the heating element. It should be
approximately 14 ohms.
2. Check the resistance between ground and both heater terminals. It
should be open when the heater terminals are disconnected.
Test 15
Check wiring between the main control board and motor control
board.
Test 16
1. Are the hot and cold water hoses switched?
2. Is the HOT water about the same temperature as the cold?
Test 17
1. Check wiring between main board and pump.
2. Check wiring between main control and recirculation board.
3. Check pump for open coil (resistance check).
Test 18
1. Check power in for voltage under load.
2. Check power wiring to main board.
3. Check wiring to motor board for short to power or ground.
Test 19
Check wiring to main board. Unplug the unit for 1 minute and retry.
Test 20
Unplug and reseat connector between UI boards.
Test 21
Check wiring to recirculation pump
Check/Test Activity Steps
No, replace the motor.
Yes, go to step (2).
No, check the tub bearings.
Yes, go to step (3)
If the readings are correct, check wiring from motor to motor control board, If good,
replace the motor control board.
If the readings are incorrect, replace the motor.
No, replace the motor.
Yes, go to step (2).
No, check the tub bearings.
Yes, go to step (3).
If the meter reads other than between 105 to 130 Ohms, replace the motor. If the
reading is between 105 to 130 Ohms, go to step (4).
If the readings are correct, replace the motor control board.
If the readings are incorrect, replace the motor.
If wiring is bad, correct wiring problem.
If wiring is good, replace the main control board. If the problem is not corrected,
replace the user interface board.
If wiring is bad, correct wiring problem.
If wiring is good, replace the user interface board. If the problem is not corrected,
replace the main control board.
If correct, for error code E5C, replace the motor control board.
If correct, for error codes EA1, EA2, EA3, EAE or EA5, replace the main control board
No, replace the NTC sensor
Yes, check the wiring.
If the reading is incorrect, replace the heating element.
If the reading is correct, move to the next step.
If the readings are incorrect, replace the heating element. If the problem is not
corrected, check the wiring, If wiring is OK, replace the main control board.
If wiring is good, replace the motor control board.
Yes, switch the hoses to correct position
No, go to step 2
Yes, fi x the HOT water in the house supply.
If OK, then go to step (2).
If OK, then go to step (3).
If OK, then replace main control.
Correct supply or branch circuit issues.
No problem go to step 2.
Yes, fi x wiring or plug to main board.
