- If the inlet valve contains a 110 volt connection for the power brush, verify
it is live. Either test with a voltmeter or plug the power brush cord directly into
the inlet. Note: Some electric power brushes require the neck to be
tilted prior to activation and will not work in the upright position.
If the electric power brush activates, the problem is within the hose.
- Watch our Troubleshooting an Electric Central Vacuum Hose Videos to identify the point of failure.
- If the issue is a faulty switch assembly, see Replacement Hose Switch Options.
- If the issue is due to a faulty diode fuse, see Replacement Wall End Hose Parts.
- If the issue is a break in the high voltage wiring within the hose, it cannot be repaired and a new hose is required. Check out our Replacement Electric Hoses for industry-standard hose options.
If the electric power brush does not activate, the problem may be within the power brush or
within the electric inlet valve(s).

- Check the power brush reset button and, on some central vacuums, the neck-tilt-switch by listening for it to pop out just before the neck goes into the upright position. It may be jammed with debris, such as lint.
- Check that the roller brush can spin smoothly because the bearings may be jammed with hair or debris.
- Open the vacuum head and apply power directly to the motor.
- If it operates correctly for 10 minutes, it is likely not the problem.
- If it quits, check the service manual for the particular brush or replace the vacuum head, if compatible with your hose and connection wands (vacuum head motors cost nearly as much as a new head).
- Alternatively, replace the hose, head, and accessories with a new Complete Attachment Kit, compatible with all central vacuum systems.
- Electric Inlet Valve
IMPORTANT: Ensure the power is shut off prior to working on the valve or have a qualified electrician make repairs.
- Check if the valve or electrical inlet is connected through a GFI (Ground Fault Circuit Interrupter) outlet, which may be located in a bathroom. This can easily be reset.
- Replace inlet(s). See our Replacement Central Vacuum Electric Inlet Valves for information on how to replace the inlet(s) as well as replacement options.
