TROUBLESHOOTING TESTS
TEST #1 Supply Connections
This test assumes that proper voltage is present at the outlet.
1. Unplug washer or disconnect power.
2. Access the machine/motor control assembly. See Accessing & Removing the Electronic Assemblies.
3. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and P13-1 on the machine/motor control.
See Figures 3 and 4, page 6-16. If there is continuity, go to step 4. If there is no continuity, replace the power cord.
4. In a similar way, check the continuity between the L1 terminal of the plug and P13-3 on the machine/motor control. See
Figures 3 and 4, page 6-16. If there is continuity, go to step 5. If there is no continuity, replace the power cord.
5. Visually check that the P10 connector is inserted all the way into the machine/motor control.
6. Visually check that the user interface assembly is properly inserted into the front console.
7. If both visual checks pass, replace the user interface assembly. See Reinstalling the Electronic Assemblies.
8. Plug in washer or reconnect power.
9. Activate the Console and Indicators Diagnostic Test mode to verify repair.
10. If indicators still do not light, the machine/ motor control has failed: Unplug washer or disconnect power. Replace the machine/motor control assembly.
Plug in washer or reconnect power.

TEST #2 Log Valve
This test checks the electrical connections to the valves, and the valves themselves.
1. Check the relays and electrical connections to the valves by performing the steps under Diagnostic: Manual, then Manual: Water Valves. Each step in the test activates a group of valves. The following steps assumes one (or more) valve(s) failed to turn on.
2. For the valve(s) in question check the individual solenoid valves: Unplug washer or disconnect power. Disconnect connector P1 and P2 from the machine/motor control.See Figure 4, page 6-16. Check harness connection to solenoid valves.
3. Check resistance of valve coils at contacts P1 and P2 shown in the Wiring Diagram on page 7-1. Resistance values should match those shown.
If resistance readings are tens of ohms outside of range, replace the entire log valve assembly. If resistance readings are within range, replace the machine/motor control assembly.
4. Reconnect connectors P1 and P2 to the machine/motor control.

TEST #3 Motor Circuit
This test checks the wiring to the motor and rotor position sensor; and the motor and rotor position sensor themselves. NOTE: Drain water from tub.
1. See Activation of Manual Diagnostic Test Mode, and check the motor and electrical connections by performing the Agitate and Spin tests under Manual: Motor. The following steps assumes that this stepfailed.
2. Unplug washer or disconnect power.
3. Check to see if basket will turn freely. If basket turns freely, go to step 4. If basket does not turn freely, determine what is causing the mechanical
friction or lock up.
4. Remove the console to access the machine/ motor control assembly. See Accessing& Removing the Electronic Assemblies.
5. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control. If visual checks pass, go to step 6.
If visual checks fail, reconnect P5 and P10 and repeat step 1.
6. With an ohmmeter, check for 16 ohms resistance at the P5 connector between pins P5-1 and P5-2, and also between pins P5-1 and P5-3. Also measure the resistance at the P10 connector between pins P10-1 and P10-7 and verify that the resistance is within the range shown in the wiring diagram on page 7-1.
If the resistance is correct, go to step 11. If the P5 connector resistance is much higher than 16 ohms, or the P10 connector resistance is out of range, go to
step 7.
7. Tilt machine forward to access the bottom of the machine and the drive motor area. See Figure 1 on page 6-13. Remove the motor bolt, then the motor cover to access the motor connections. See Figure 2 on page 6-13.
8. Visually check the mounting bracket and electrical connections to the motor and rotor position sensor board. If visual check passes, go to step 9.
If visual check fails, reconnect the electrical connections, reassemble stator and motor cover and repeat step 1.
9. With an ohmmeter, check for continuity between all pins on the P10 machine/motor control connector and the motor rotor position sensor (RPS) connector. See Figures 2 and 4, pages 6-13 and 6-16. If there is continuity, go to step 11. If there is no continuity, replace the lower machine harness.
10. With an ohmmeter, check for continuity between all pins on the P5 machine/motor control connector and the drive motor connector. If there is continuity, replace the drive motor. If there is no continuity, replace the lower machine harness.
11. The drive motor and lower harness are good. Replace the motor RPS board and perform the Diagnostics test in step 1 to verify repair.

5. Drain the tub until all water has been removed from tub.
6. Remove all clothes from the machine.
7. Calibrate the pressure transducer: See Activation of Manual Diagnostic Test Mode, and perform steps 1 and 2 until the display shows 00 and the Add
A Garment indicator LED is flashing. Press and hold the Cycle Signal button until a single beep sounds, and the display shows Pt to indicate zero calibration
has completed. Exit Diagnostic: Manual by pressing STOP or POWER.
8. Select POWER • wash cycle NORMAL • START.
9. Verify that the tub fills to the top of the impeller plate (impeller models), or to a level above the agitator vanes (agitator models), but much lower than the SUPER Load Size water level. If the water level does not fill to this level, replace the machine/motor control assembly. See Accessing & Removing

2. Remove the console to access the machine/ motor control assembly. See Accessing & Removing the Electronic Assemblies.
3. Visually check that the P4 connector is inserted all the way into the machine/motor control. If visual check passes, go to step 4. If visual check fails, reconnect P4 and repeat step 1.
4. Remove connector P4 from the machine/ motor control and check resistance values of pump motor windings. Resistance values should match those shown in wiring diagram, page 7-1. If resistance values are good, go to step 7. If winding measurements are much higher (tens of ohms to infinity) than shown in wiring diagram, a problem exists in the motor winding or in the connection between the machine/motor control and the motor. Go to step 5.
5. Tilt machine forward to access the bottom of the machine and the pumps. See Figure 1, page 6-13.
6. Check the resistance at the pump motor. Remove the connector at the motor and take measurements across pump terminals. Measurements should be as shown in the wiring diagram. If winding measurements are much higher (tens of ohms to infinity) than shown in wiring diagram, replace the pump motor. If the resistance at the pump motor is correct, there is an open circuit in the wiring between the motor and the machine/ motor control. Repair or replace the lower wiring harness. If the pump motor windings and machine/ motor control check OK, repair or replace the pump. Be sure to check the pump and tub sump for foreign objects before replacing pump.
7. See Activation of Manual Diagnostic Test Mode, and perform the Manual: Pumps test.
8. If the Manual: Pumps test failed, then the machine/motor control has failed: Unplug the washer or disconnect power. Replace the machine/motor control assembly. Perform the Manual: Pump test.

TEST #8 Door Lid Lock
Perform the following checks if washer fails to lock (or unlock).
1. Perform Manual: Door Switch and Manual: Door Lid Lock tests.
2. Remove the console to access the machine/ motor control assembly. See Accessing & Removing the Electronic Assemblies.
3. Visually check that the P12 connector is inserted all the way into the machine/motor control. If visual check passes, go to step 4. If visual check fails, reconnect P4 and repeat step 1.
4. Check the lid lock motor winding and switches by removing P12 from the machine/ motor control and checking the
resistance values shown in the Lid Lock Resistance table below:

LID LOCK RESISTANCE

Component Resistance
Unlocked
Resistance
Locked
Contacts Measured Contacts Measured
Motor Winding 35 ±5 Ω 35 ±5 Ω P12-2 P12-3
Lock Switch - Home 0 Ω Open Circuit P12-1 P12-4
Lock Switch - Lock Open Circuit 0 Ω P12-1 P12-7
Lock Switch - Lid Lid Closed = 0 Ω
Lid Open = Open Circuit
Lid Closed = 0 Ω
Lid Open = Open Circuit
P12-1 P12-5

If resistance values are good, go to step 5. If switch measurements do not match the values shown in the table for unlocked (or locked) conditions, a problem
exists in the door lid lock. Replace the door lid lock.
5. If the Manual: Door Switch or Manual: Door Lid Lock in step 1 failed, then the machine/motor control has failed: Unplug washer or disconnect power.
Replace machine/motor control assembly. Perform the Manual: Door Switch and Manual: Door Lid Lock in step 1 to verify repair.
