Some central vac systems have an On/Off Switch on the tank.  You could turn on the vacuum from the tank and try reversing the hose by placing it up to the inlet.  In most cases, that end of the hose will not fit cleanly into the inlet, but the suction from the inlet may be enough to dislodge the hose blockage.  Another, perhaps simpler method, is available to those who have a canister vacuum in addition to their central vacuum system.  If so, you can adjoin the hoses, as best you can, and use the canister to dislodge a hose blockage in your central vacuum.  Note – it may require more than one try, so you may need to change the end of the central vac hose various times.

• Be sure your lid is properly closed and check that all clips are a firmly clasped.
• Check for frayed wires on the exterior of the tank.  If present – call for Service!
