Washer-dryer combo produces a high-pitched squealing or screeching noise when spinning or tumbling.

Safety first: Unplug the appliance before removing any panels.

• Check for foreign objects: Spin the drum by hand. If you hear scraping, there may be a foreign object between the inner drum and outer tub. Inspect the drum holes with a flashlight.
• Inspect belt and pulleys: Remove the rear panel. Check the drive belt for cracks, glazing, or fraying. Inspect the motor and drum pulleys for damage or misalignment.
• Replace belt: If the belt is worn, slip it off the pulleys and install a new Fisher & Paykel drive belt, ensuring correct routing and tension.
• Check bearings: If the squeal is accompanied by roughness when spinning the drum by hand, the tub bearings may be failing and require professional replacement.
