F06 code ran the diagnostic test and it did not fail. Check the motor resistance all three tested right at 6 ohms, the tach tested at 118 ohms. Checked the harness between the motor and the mcu all wire good with no shorts between. What the next test can I do or do I replace the mcu?

Ld flashes when the water level does not change after the drain pump is on.
Is the drain hose or the drain pump clogged?
Is the drain hose height greater than 96? ?
Is the pump running? If not, see TEST #7.
TEST #7 Drain/Recirculation
Perform the following checks if washer fails to drain or recirculate.
1. See Activation of Manual Diagnostic Test Mode, and perform the Manual: Pumps test.
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.

wow i like a customer who has done their homework :) based on all you have checked,if i were in the home, as the technician would recommend to you to have the drive motor replaced since the biult in tachometer isn't telling the mcu what rpm's it has spun at

Hello,


The F51 error code refers to a failure on the rotor position sensor,the test procedure for testing the RPS can be quite involved. Here is the test procedure

;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.
12. If the Diagnostics motor test in step 1 failed, then the machine/motor control has failed: Unplug the washer or disconnect power. Replace the machine/motor control assembly. Perform the Motor Diagnostics in step 1 to verify repair

The F50 error code indicates that the RPS (rotor position sensor) detects no motor rotation. Check to see if the basket spins freely. If not, you could have an item caught between the outer tub and the inner spin basket. A toy or other item underneath the washer could also prevent the basket from spinning and would result in this F50 code.

If the basket spins freely, you could have a wiring failure that would prevent the motor from spinning.

The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 - is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.

NOTE: All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.
