I've been getting 2 different error codes. One is an F1 E2 and the other is an F6 E2. I get the F1E2 more often. I've cycled the power and checked all of the connections that I can. Do you think it is the CCU or the MCU? If I by one and it doesn't work, can I return it to get the other?
The F1 E2 error is a MCU Error with multiple resets. Motor Control Unit (MCU) has an internal malfunction, repeating under or over voltage, or over current conditions. Can also be caused by momentary loss of neutral feed to MCU during the spin cycle. If the error occurs during a high-speed spin, the door will remain locked for 3 minutes.
TEST #3: Motor Circuit
This test checks the motor, motor control unit (MCU), and wiring. IMPORTANT: A guide (W10271535) is required to assemble the rotor onto the shaft. The guide is inserted into the threaded hole, and then the rotor is slid on over the guide.
NOTE: If the harness between the CCU and MCU is removed or communications are interrupted during operation, the MCU puts the motor into a braking mode, resulting in a significant drag on the drum when turned by hand. This mode can be cleared by removing power from the washer for a few seconds.
1. Check the motor and electrical connections by performing the “Quick Diagnostic Test” on page 6. The following steps assume that this
step was unsuccessful.
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 lockup.
4. Remove the top and rear panels to access the machine electronics and motor components.
5. Visually check that connectors MS2 and MI3 are inserted all the way into the CCU. If visual checks pass, go to step 6. If visual checks fail, reconnect MS2 and MI3, and repeat step 1.
6. Visually check that all connectors are inserted all the way into the MCU (see Figure 6, at left). If visual checks pass, go to step 7. If visual checks fail, reconnect the MCU connectors and repeat step 1.
7. Check the motor windings. Disconnect the motor harness from the MCU. With an ohmmeter, verify the resistance values as shown below:
Motor Harness Winding
Pin 1 & 3 8.5 - 14.0 ohms
Pin 2 & 3 8.5 - 14.0 ohms
Pin 1 & 2 8.5 - 14.0 ohms
If the values are outside the range or open, replace stator assembly; otherwise, reconnect the motor harness and go to step 8.
8. Check the two harnesses between the CCU and MCU for continuity. If there is continuity, go to step 9. If there is no continuity, replace the main lower harness.
9. With a voltmeter set to AC, connect the leads across pins 1 and 2 of connector MS2.
10. Plug in washer or reconnect power.
F2 code has been coming up for awhile. Techs come in clean filters. I clean them often. Their not clogged or blocked-drum doesn't spin. I start wash cycle, it doesn't finish but gives f2 code. I change cycle to rinse and drain and speed of spin from high to medium and works once then next wash cycle I do same but have to try slow spin. Husband already placed new drain pump. He s wondering if he should try one of control panel. Which or what do you think is wrong. Thank you for your help
With the issue that you are having with the F2 error code you will want to check the pressure hose to ensure that it is not clogged. Also check the connectors at the control board and at the drain pump for corrosion and if there is any corrosion then you would want to clean with a contact cleaner. Also check the hose that comes from the bottom of the tub to the drain pump for any debris that may be in it. Clear any out if found. If all this checks ok then the main control board 8182695 would be the most likely issue.
Hello, I have been looking at the other feeds. I have an F6 code error. When I ran the diagnostic check the motor never spun. I looked at the connectors and plugged/unplugged. Just put a new motor in and same code. From what I am reading, it sounds like the MCU, your thoughst? Thanks for your time,
Answer Hello Dave. Per the manufacturer • Check wire harness connections between the Drive Motor/Tachometer and the Motor ControlUnit (MCU), and between the MCU and the Central Control Unit (CCU)
• Check the Drive Motor
• Check the MCU
• Check the Wire Harness
If harness is good then the mcu will probably be the issue.
Need to replace the controller to fix a F30 error. Do you have this in stock?
Answer Hello! Yes, the motor control unit 8182706 is currently in stock and available to order. Thanks.
I am getting error code F11 indicating that the MUC board needs to be replaced. Is that correct? Could it be anything else? If so, is this the correct part number is 8182706.
Answer Hello Ross. Communication between the Central Control Unit (CCU)
and the Motor Control Unit (MCU) cannot be sent
correctly. Possible Causes / Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the
motor, and Central Control Unit (CCU).
3. Check the drive system for any worn or failed
4. Plug in washer or reconnect power.
5. Verify CCU operation by running a Diagnostic test or
6. Check the MCU by looking for operations of the drive
7. Check the drive motor for powered rotations.
8. Check that the serial harness at the MCU is not
mounted upside down. The wires should be to the left
when facing the MCU connectors.
What can cause the electrical board 8182706 burned?
A electrical circuit board can be burnt by a power surge or possibly a bad wire harness connection, a bad motor for this board or possibly just went bad.
