How to Repair a Central Vacuum

Central vacuum systems are a way for you to keep your home clean without having to carry heavy equipment around from room to room. However, like most appliances, it is possible to experience performance issues with your central vacuum system. The problems you face can vary depending on the model you are using, and the solutions available can vary depending on the problem you encounter.

  1. Check for blockages in the hose if the vacuum power is low. Place the handle end of the hose in the utility valve next to the main power unit, then switch the main unit on. This causes a reverse in the normal air flow that should remove anything blocking the hose.

  2. Check the main unit if it suddenly stops during operation or does not turn on. If none of the LED lights flash red, turn the unit off and unplug it. Wait for 20 minutes, then plug the unit back in and turn it on.

  3. Check the main unit if it suddenly shuts off during operation. If the LED lights are flashing red, the filter bag is full and needs to be replaced with a fresh one. Replace the current bag with a new one, then hit the "Reset" button on the main unit.

  1. Check the main unit's power cord if it suddenly stops working or does not turn on. If it is not securely plugged in to an electrical socket, securely plug it in. If there is another electrical socket available, try plugging the unit in to that to make sure the one it is currently plugged in to is not damaged.

  2. Press the "Reset" button on the main unit if it suddenly stops working in the middle of normal operation.

  3. Change the debris bucket or check if the bag is full if you experience lower vacuum power. If it is, replace the full bag with a new one. Press and hold the "Reset" button on the main unit for seven seconds after replacing the bag.
