I have a NFW7200TW Amana Washer. The problem is my wife said she saw a E3 error and then a nd error. I fixed the pump for the nd error but I don't know what the E3 error is. When I tried to run th


E3 Error: Machine control is attempting to drive the motor but is not seeing any tach response. Visual check shows motor is not moving. (Locked, Hall Sensor fault). Replace the hall sensor.
The "hall" sensor is an internal circuit of the motor. It "tells" the machine control board, what the motor is doing, it's similar to a tachometer on the dashboard of a car. In your case, you want to do the resistance checks on the wires of the CN9 and CN8 connectors at the main control board in the front of the washer (it's easier and more indicative). Unplug the CN9 connector from the control board(red, white and blue wires) testing the pins inside the wire harness connector: from pin#1 /blue to pin#2 /white you should read 3 ohms resistance from pin#1 blue to pin#3/red, you should read 3 ohms resistance. from pin#2/white to pin#3/red, you should read 3 ohms resaistance. That will tell us the motor windings are damaged or not. At the CN8 connector, unplug the connector from the control board and insert the meter probes into the end of the wire harness connector; pin#4/orange to all other pins in the connector should have infinite resistance. pin#3/blue to pin#1/pink should have 4.7 ohms resistance. If you have these resistances, the motor and wiring are OK and you'll need the control board. If the resistances are not within 10% of the ones listed, you'll need to check the wiring harnesses and connections from the control board to the motor, and replace the motor if all checks OK.
Here is a link to the motor.

Code f50 is what?


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.

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.

I have a whirlpool duet, I am running into an error of F6E1 in the display.Could you let me know what is to be done?


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.

here is what test 3 is... good luck...

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

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.
