Washer-dryer combo will not spin or tumble; display shows F06 and may beep repeatedly.

Safety first: Unplug the unit before accessing the motor or control board. The drum and motor can move unexpectedly.

Step-by-step checks:

• 1. Access motor: Remove the rear panel. Locate the drive motor at the bottom rear of the tub, connected to the drive belt.
• 2. Inspect wiring harness: Check the multi-pin connector at the motor and follow the harness to the control board. Look for loose plugs, broken wires, or signs of rubbing against the cabinet. Reseat all connectors firmly.
• 3. Check drive belt: Ensure the belt is on both the motor pulley and the drum pulley. If it is off or badly worn, replace it. A slipping belt can trigger motor errors.
• 4. Test motor windings: Disconnect the motor. Use a multimeter to measure resistance between motor terminals as specified in the tech sheet (typically a few ohms). Open or shorted windings indicate a bad motor.
• 5. Inspect tachometer (if external): Some Maytag motors have a separate tach sensor. Ensure it is firmly attached and its wiring is intact. If the tach is integrated and readings are erratic, the motor must be replaced.
• 6. Control board check: If motor and wiring test good, the motor drive circuit on the main control board may be defective and require replacement.

Warning: Do not bypass motor safety circuits; this can cause fire or injury.
