The most common Dyson vacuum cleaner problems that you can fix yourself include loss of suction due to a dirty or damaged filter and problems with the belt and brushbar. Repairing your Dyson vacuum yourself may change or void your warranty, depending on what you do to the vacuum. If you are unsure how to remove parts from your vacuum, consult the manual that came with the appliance for specific diagrams and instructions.
One of the most common problems with Dyson vacuums occurs when the filter gets too dirty or becomes clogged. Regularly cleaning your filter can help you avoid burning your motor out before its time. The filters are located in various places on different Dyson models. You can usually find the filter on the side of the vacuum beneath the canister or on the top of the canister. Wipe out the inside of the filter housing and wash the filter and sponge in warm, soapy water. Rinse and dry the filter thoroughly before replacing it in your vacuum.
Belt and Brushbar Repair
The brushbar on a Dyson vacuum may begin to make a whining sound over time due to friction on the bearings. Oil the bearings with a lubricant, such as WD-40, to help quiet the noise. If your Dyson vacuum has suction from the hose but is not picking up debris when you vacuum normally, check the belt to see if it has snapped or broken. Unplug the vacuum and lay it on its side so that you have easy access to the parts under the head of the vacuum. Unscrew the screws that hold the plastic cover in place. Remove the belt from inside the vacuum near the motor so that you can remove the brushbar. The brush bar may have a string or piece of cloth wrapped around it that is preventing it from spinning. Remove anything that is wrapped around the brushbar. Replace the belt if it snapped or if it feels stretched out and loose. Purchase a Dyson belt from a local retailer or online store. Make sure to select the appropriate belt for your particular model. Slide one end of the belt over the grooves on the brushbar and snap the brushbar back into place. Loop the other end of the belt around the motor shaft and replace the plastic cover over the bottom of the vacuum, tightening the screws in place.
