A blockage in the air passage, including a plugged filter, is a major contributor to motor burn out.
To reduce the chance of motor burn out and improve the performance of your vacuum, follow these simple procedures:
Inspect the service ports* and hose for obstructions on a regular basis.
Pop-up pins used on some machines to indicate that it is time to change the HEPA filter have proven to be very unreliable. If your machine is constantly blowing the on-board thermal overload switch, your machine is very close to burning out the motor and presents a serious fire risk. Inspect and clean immediately. If the thermal overload switch problem persists have a qualified vacuum repair technician inspect your machine.
A test to see if the filter is plugged would be to first clean the main dirt canister then remove the HEPA filter and turn on the vacuum. If you notice an increase in suction power at the end of the hose then the filter needs to be replaced. This test is best done outside on a dry day where any expelled dust will not be a problem.
Maximizing the Life of your HEPA Filter.
To maximize the life of the new HEPA filter,
perform routine cleaning* of the vacuum cleaner prior to installation.
* Refer to your vacuum cleaner manual for instructions specific to your machine. All maintenance performed on the machine must be done while the machine is unplugged from the power source.
