Having problems with your Vacuums ?

I have a central vacuum system. When I disconnect the hose from a wall outlet the central canister does not shut down dispite my turning off the vacuum at the handle of the hose. The only way I can get the system to shut down is to pull the plug at the canister. What gives? Rob


Answers :

What I'm hearing is the canister(Not the Powerhead) portion of the unit is running all the time unless you unplug it. this problem could be caused by a short in one of your low voltage lines running through the house. To determine that just unplug one/both low voltage lines from the canister, and plug it back into the recepticle. If it doesn't start up then you figured out that it is in the house somewhere and not the unit. If it is in the house I would check for water in the valves, or you're just gonna have to chase down the short. If the unit is still running with the low voltage wires disconnected then it is probably the relay on the board, which means you will need a new board unless you're expereinced at soldering and want give it a try replacing just the relay. Which you'll probably need a new board by the time you're done anyhow. LOL

Changed the motor carbon brushes on my Beam central vacuum cleaner equiped with an IntelliWatch system. This system includes the Alutron DB100 module. This Alutron module needs to be reset so that the vacuum cleaner can operate properly. I believe that this module keeps log of running time and disables operation after a predetermined time. Can you help me with providing a reset procedure that will reset this module. Thanks

Motor My vacuum cut out as I was using it. After some experimenting I found that the circuit reset had gone off. When I tried a second time while near the motor , there was a flash and again the motor shut off. At this time I am guessing that the motor is faulty. The central vacuuming is approximately 12 years old.


If it tripped the reset again, I would probably agree with you. Check out centralvacuum.com for another motor. They aren't the cheapest, but they have excellent support. Good Luck!! ... Easy Flo EF1400 Central System Vacuum
