How to Troubleshoot a Whistling Sound on a Hoover WindTunnel
Vacuuming your carpet with a whistling Hoover WindTunnel vacuum cleaner is not only annoying, it reduces the efficiency of the machine because it's leaking. Leaks reduce the vacuum cleaner's ability to create suction and pick up dirt from the carpet. Whistling can indicate a leak from virtually anywhere, so troubleshooting is a vital part of diagnosis and repair of a Hoover WindTunnel. Does this Spark an idea?

Locate the hose attachment coupler on the right side of the vacuum cleaner's base. Press the release button and disconnect the attachment hose.

Turn on the vacuum cleaner and listen for the whistling sound. If the whistling stopped, the hose has a pinhole or rip in it that caused the whistling. The hose gasket on the vacuum base may also be defective. Inspect the gasket for any evidence of tearing or defect. If the whistling persists after removing the hose, move to the next step.

Press the canister release button to remove the canister from the front of the WindTunnel and empty out the dirt. Remove the filter and replace it with a new one. Turn on the vacuum cleaner with the canister removed. If the whistling goes away, the seal between the top of the canister and the housing is likely dirty. Wipe the seal clean with a wet rag and reinstall the canister. If the vacuum cleaner still whistles, inspect the canister for cracks in the housing. If you cannot locate any, move to the next step.

Light an incense stick and turn on the vacuum cleaner. Move the stick up and down along the outer housing of the vacuum cleaner. If the vacuum is sucking in air through the housing, the smoke from the incense stick will pull into the crack as you pass it, helping to identify any areas in the housing causing the whistling.
