5. Maintenance

5.1. Emptying the Dust Bin

The vacuum features a 4/9-gallon dust bin. Empty the bin when debris reaches the MAX fill line.

1. Remove Bin: Press the bin release button to detach the dust bin from the main unit.
2. Empty Debris: Hold the bin over a trash receptacle. Press the red button to open the bottom flap and release the collected debris.
3. Reattach Bin: Close the bottom flap securely until it clicks into place. Reattach the bin to the main vacuum unit.

5.2. Cleaning the HEPA Filter

The DC21 includes a lifetime HEPA filter designed to capture microscopic particles. Regular cleaning ensures optimal performance.

1. Locate Filter: Identify the filter compartment, typically positioned near the dust bin.
2. Remove Filter: Carefully remove the HEPA filter.
3. Wash Filter: Wash the filter with cold water only. Do not use detergents or place in a dishwasher.
4. Dry Filter: Allow the filter to air dry completely for a minimum of 24 hours before reinserting. Ensure it is absolutely dry to prevent damage to the motor.
5. Reinstall Filter: Once dry, reinsert the filter into its compartment and secure it.

6. Troubleshooting

Problem: No Power

• Check if the power cord is securely plugged into a functional electrical outlet.
• Verify the outlet is operational by testing with another appliance.
• Check for tripped circuit breakers in your home's electrical panel.

Problem: Loss of Suction

• Empty the dust bin if it is full or debris has reached the MAX fill line.
• Inspect the hose, wand, and cleaning head for any blockages and remove them.
• Ensure the HEPA filter is clean and completely dry before reinstallation.
• Verify all connections (hose to unit, wand to hose, cleaning head to wand) are secure.

Problem: Brush Bar Not Rotating

• Ensure the brush bar on/off switch is in the 'on' position.
• Check for obstructions such as hair, threads, or debris wrapped around the brush bar. Carefully remove any entanglements.
• If the brush bar bogs down on thick carpet, it may be due to excessive resistance; ensure the brush bar is clean and free of debris.
