Let’s get started and bring your vacuum back to life!

This article is designed to provide you with a comprehensive guide to troubleshoot your Shark NV800W vacuum. We’ll cover everything from basic checks to more advanced troubleshooting steps, including how to check power sources, clear blockages, inspect the motor, and more. By the end of this article, you should have a solid understanding of why your vacuum isn’t working and how to fix it, saving you time and money.

Check the Power Source

A dead outlet or a tripped breaker is the most common reason a vacuum won’t start. Let’s rule this out first before assuming there is a major mechanical problem.

1. Test the Outlet: Plug another appliance into the same outlet to see if it works. If it doesn’t, the problem is with the outlet, not the vacuum.
2. Check the Breaker: If the outlet isn’t working, check your home’s circuit breaker. Reset any tripped breakers.
3. Try Another Outlet: Plug the Shark NV800W into a different outlet on a different circuit to ensure the problem isn’t isolated to one specific area.

Inspect the Cord and Plug

Damage to the cord or plug can prevent the vacuum from receiving power. A frayed cord can be a fire hazard so it is important to diagnose the problem before using the vacuum.

1. Examine the Cord: Look for any visible signs of damage, such as cuts, frays, or exposed wires.
2. Check the Plug: Ensure the plug is securely attached to the cord and that the prongs are not bent or broken.
3. Test the Cord (Advanced): If you have a multimeter, you can test the cord for continuity. If there’s no continuity, the cord needs replacement. If you are not comfortable with using a multimeter, consult an electrician to avoid any potential injuries.

Clear Blockages in the Hose, Wand, and Nozzle

Blockages are a frequent culprit for vacuum problems. Over time, debris can accumulate in various parts of the vacuum, obstructing airflow and causing the motor to overheat or shut down.

1. Detach Components: Separate the hose, wand, and nozzle from the main body of the vacuum.
2. Inspect the Hose: Look through the hose to identify any visible blockages. Use a broom handle or similar tool to dislodge any obstructions.
3. Check the Wand: Inspect the wand for blockages, using the same method as with the hose.
4. Examine the Nozzle: Remove any debris from the nozzle, paying close attention to the brush roll area. Clear any tangled hair or fibers that could be causing a blockage.
5. Reassemble and Test: Once all components are clear, reassemble the vacuum and test if it powers on.

Clean or Replace the Filters

Dirty filters can restrict airflow and cause the motor to overheat, leading to shutdown.

1. Locate the Filters: Refer to your Shark NV800W’s manual to find the location of the filters. Typically, there are pre-motor and post-motor filters.
2. Remove the Filters: Take out the filters from their housing.
3. Clean the Filters: Tap the filters gently over a trash can to remove loose dirt and debris. Wash the filters with lukewarm water and mild detergent. Rinse thoroughly until the water runs clear.
4. Dry the Filters: Allow the filters to air dry completely (usually 24 hours) before reinstalling them.
5. Reinstall and Test: Place the dry filters back into their housing and test the vacuum.
6. Replace if Necessary: If the filters are damaged or excessively dirty, consider replacing them altogether.

Check the Brush Roll

A jammed brush roll can cause the vacuum to overheat and shut off as well.

1. Turn Off and Unplug: Always turn off and unplug the vacuum before inspecting the brush roll.
2. Locate the Brush Roll: Find the brush roll access panel on the vacuum nozzle.
3. Remove Debris: Clear any hair, string, or debris tangled around the brush roll. Use scissors or a seam ripper to cut away stubborn tangles.
4. Check for Damage: Inspect the brush roll for any signs of damage, such as broken bristles or a bent frame.
5. Reinstall and Test: Put the brush roll back in place, close the access panel, and test the vacuum.

Reset the Motor Overheat Protection

Many vacuums, including the Shark NV800W, have a thermal cutoff switch that trips when the motor overheats.

1. Unplug the Vacuum: Disconnect the vacuum from the power outlet.
2. Allow to Cool: Let the vacuum sit unplugged for at least 30-60 minutes to allow the motor to cool down.
3. Check for Blockages: Before restarting, ensure there are no blockages in the hose, filters, or brush roll that could have caused the overheating.
4. Plug and Test: After the cooling period, plug the vacuum back in and try turning it on.

Inspect the Motor

If none of the above steps work, the motor itself might be the problem.

1. Listen for Unusual Noises: When you try to turn on the vacuum, listen for any strange sounds coming from the motor, such as grinding or whining. These noises can indicate motor damage.
2. Check for Burning Smell: A burning smell can indicate that the motor is overheating or has an electrical short.
3. Professional Inspection: Motor issues often require professional attention. Contact Shark customer service or a qualified repair technician to inspect and repair the motor.

Tips, Warnings, and Best Practices

• Regular Maintenance: Regularly clean the filters and brush roll to prevent future issues.
• Avoid Overfilling: Don’t overfill the dust cup, as this can reduce suction and strain the motor.
• Don’t Vacuum Liquids: Avoid vacuuming liquids or wet debris, as this can damage the motor.
• Unplug Before Maintenance: Always unplug the vacuum before performing any maintenance or troubleshooting steps.
• Professional Help: If you’re uncomfortable performing any of these steps, seek professional help.

FAQ Section

Why does my Shark vacuum turn on for a few seconds and then shut off?

This issue often indicates that the motor is overheating due to a blockage or dirty filter. Check and clear any blockages in the hose, wand, and nozzle. Also, clean or replace the filters to ensure proper airflow and allow the vacuum to cool down before trying again.

How often should I clean the filters on my Shark NV800W?

It is recommended to clean the pre-motor filters at least once a month and the post-motor filter every three months. However, if you use your vacuum frequently or have pets, you may need to clean the filters more often. Regular cleaning helps maintain optimal suction and prolongs the life of your vacuum.

Can a full dust cup cause my Shark vacuum to not turn on?

Yes, a full dust cup can reduce suction and strain the motor, causing it to overheat and potentially shut down. Empty the dust cup regularly, ideally after each use, to ensure the vacuum operates efficiently and prevent motor issues.

What does it mean if my Shark vacuum smells like it’s burning?

A burning smell typically indicates that the motor is overheating or there’s an electrical issue. Immediately turn off and unplug the vacuum. Check for blockages in the hose, filters, and brush roll. If the smell persists after clearing any obstructions, contact a professional repair technician, as it could signify a more serious motor problem.

How do I know if my Shark vacuum’s brush roll is properly installed?

The brush roll should spin freely without any resistance when the vacuum is turned on. Ensure the brush roll is securely placed in its housing and that the access panel is properly closed. If the brush roll is not spinning or is making unusual noises, recheck the installation and remove any tangled debris that may be causing interference.

Conclusion

Troubleshooting why your Shark NV800W vacuum won’t turn on can seem daunting, but by following these steps, you can often identify and resolve the issue yourself.
