Washer-dryer combo will not spin or tumble; display shows F06 and may stop shortly after starting a cycle.

Safety first: Disconnect power and avoid rotating parts. The drum and motor can move unexpectedly.

Step-by-step checks:

• Access the drive motor: Remove rear panel. Locate the drive motor at the bottom rear of the tub with a belt (belt-drive) or directly attached (direct-drive).
• Inspect wiring: Check the motor connector and tachometer wires for looseness, broken conductors, or corrosion. Reseat all connectors.
• Check belt (if equipped): Ensure the drive belt is intact and properly tensioned. A slipping belt can cause speed sensing errors.
• Test tachometer: On motors with a tach coil, measure resistance across tach terminals (often a few hundred ohms). If open or shorted, the motor assembly may need replacement.
• Brush inspection (if brush motor): If your Whirlpool combo uses carbon brushes, remove and inspect them. Replace if worn below manufacturer’s minimum length.

When to replace: If wiring and belt are good but F06 persists, replace the drive motor assembly. If a new motor does not resolve the issue, the main control board’s motor drive circuit is likely faulty and should be replaced.
