Washer-dryer combo vibrates excessively or will not reach high spin speed; E4 appears on display.

Safety first: Keep hands clear of the drum while it is spinning. Unplug the unit before inspecting internal components.

• Redistribute the load: Pause the cycle, open the door when safe, and redistribute heavy items (e.g., towels, blankets). Remove some items if the drum is overfilled. Restart the spin cycle.
• Verify installation: Ensure the combo is level front-to-back and side-to-side using a spirit level. Adjust the leveling feet and lock them in place.
• Check for shipping bolts: If the unit is newly installed, confirm that all rear shipping bolts and transit brackets have been removed according to the NewAir installation manual.
• Inspect suspension: Unplug and remove the top or rear panel. Inspect shock absorbers and tub springs for oil leakage, cracks, or detachment. A sagging or bouncing tub indicates worn suspension.
• Replace worn suspension parts: If shocks or springs are damaged, replace them in matched sets to maintain balance. This typically involves supporting the tub, removing mounting pins/bolts, and installing compatible NewAir suspension components.
