MCU # 8182706 has a fried resistor at R6SP on back of board. What is the part # or the ohm value for the resistor.
Unfortunately we do not have information on individual components of the control board as the manufacturer does not provide this information.
I had a F21 code then a F28 code.
Answer Hello Ben,
The F21 is the code for a long drain. For this code you need to check the pump area for debris and check the pump for normal operation. As per the tech sheet: If the drain time exceeds eight minutes, “F21” will be displayed, the water valves will turn off and the pump will stop running. Press PAUSE/CANCEL to drain the machine. The display will be cleared and the machine will turn off after a maximum of eight
minutes. Possible Causes/Procedure - 1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 6. Unplug washer or disconnect power. 8. Replace the pump.
The F28 is a serial communication error. The tech sheet instructs the following for this code: The 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). Check connections of the CCU board within the housing. Make sure all grounding switches are engaged. 3. Check the drive system for any worn or failed components. 4. Plug in washer or reconnect power. 5. Verify CCU operation by running a Diagnostic Test or any cycle. 6. Check the MCU by looking for operations of the drive motor. 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.
