Washer-dryer makes a high-pitched squealing noise during spin.

Safety first: Unplug the appliance before removing the rear panel.

• Inspect belt: Check for shiny, cracked, or frayed surfaces. Replace with a correct Teka belt if worn.
• Clean pulleys: Wipe the motor and drum pulleys with a clean, dry cloth to remove detergent or oil residue.
• Check alignment: Ensure the belt runs centrally on both pulleys and that the motor mounting bolts are tight.

Warning: Do not apply lubricants to the belt; this will worsen slipping and noise.
