How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

Another reason the vacuum is not turning on may be that the circuit breaker may have tripped. Check the breaker on the unit and if it continues to fail it usually means the motor is going bad. Another reason can be the bad signal from the unit to the wall inlet.
In that case, this could indicate several issues, including a bad motor, a lack of electricity to the unit, or a tripped breaker. The vacuum may simply need resetting. If a unit won`t turn off, this is usually to do with a circuit board or relay problem.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
When using the central vacuum system, you simply plug a hose into one of the inlet valves. The hose connects to the power unit, creating a powerful suction that pulls dirt, dust and debris through the tubing system and into a collection canister.
The problem may lie in your vacuum cleaner`s adapter, charging dock, or battery and the electrical outlet. Try plugging your vacuum cleaner in to another outlet. If it is now working, the problem was in the first outlet that you have used. You should contact a certified electrician if you need to fix that outlet.
Replace the Brush Belt

If the vacuum is still hard to push, tilt it back far enough that you can inspect the moving brush while the vacuum is running. Be careful to avoid getting too close to the moving parts. If you see that the brush is not turning, that means you will need to replace the brush belt.

Why won`t my power unit shut off? Make sure the unit is in the Auto mode and that there is not a hose plugged into a wall valve. Unplug the low volt wire at the side of the unit, if the unit continues to run, the relay in the pc board is faulty and the entire pc board needs to be replaced.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
If your Roomba® i Series Robot Vacuum is not turning on or is not able to charge, rebooting your robot tends to solve most related issues. To reboot your Roomba: Press and hold the CLEAN button for 20 seconds. After you release the button, the light ring will show a white clockwise swirl while it reboots.
The problem may lie in your vacuum cleaner`s adapter, charging dock, or battery and the electrical outlet. Try plugging your vacuum cleaner in to another outlet. If it is now working, the problem was in the first outlet that you have used. You should contact a certified electrician if you need to fix that outlet.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.

I’ve just installed a hoover central vaccum SH800CA and when i plug the hose in the inlet, it doesn’t turn on. It turns on when I turn on the switch on the canister
ANSWER : The hose connects to a set of low voltage contacts inside the top of each inlet. The vac wiring is connected by a low voltage circuit to each inlet as well. your hose when plugged in completes the circuit when you turn the hose switch on. For simplicity ,I also use a coin to connect the terminals mentioned below instead of dragging the hose with you.
Reinsert the hose with the tongue or cord at 12 o clock or 6 o’clock position. If the vac does not start, rotate the hose cuff to 3 oclock.This over rides the hose handle switch to test the vac circuit.
if the vac still does not start you have a loss of LV signal in your wiring. You will need to back track to make sure you have continuity from the vac to each inlet.
if you have colored alarm or telephone type wire, it is very easy to break a wire strand while fastening so go back one connection at a time and inspect.
If you have no power to any inlets,your problem will be in the main run of wire from the vac, likely to the first connection. If you have power at only some inlets, your issue will be at one of your wire junctions, either at a pipe intersection or where two wires meet at an inlet, depending on how the system was wired.
Post back to say how you are making out

The Vaccum is not turning on when i plug the hose into the wall. The hoover system will turn on when i turn the switch on at the base and wont go off till i turn the switch off. But it will not come on automatically when i put the hose in to the wall connections.
Many Thanks
Linda
ANSWER : You can test this out by taking a small metal spoon and with the bottom side of the spoon insert it into the vac outlet on the wall. you want to touch the two metal pins inside the vac outlet to test if the unit is the problem or the hose is the problem.
.
.If the unit starts, the hose should have a 3 year warranty on it. I recommend you have your nearest beam dealer check it out.
.
.If the unit does not start, it has a 7 or 10 year warranty, the circuitry should be replaced. Again have your nearest beam dealer check it out.

.good luck

I had the vacuum cleaner question about the canister and the wand/powerhead… the Kenmore Progressive Vacuum canister model 116.25812 and the canister not powering off without unplugging the vacuum. The solution I received that they both run on their own switch so it is normal makes sense. However, is there a power switch on the canister anywhere? The only way for the canister to be turned off is by unplugging it. Any ideas? One would think there would be a switch. I am new to fixya and hope
ANSWER : Hi. On some models, one switch controls all of the power. Your issue, which is no working switch is almost certainly a blown triac on the circuit board in the canister – kenmore part number KC86WBZRZ000

Looks like a common fault with this particular model judging by the number of complaints on the web.

.Take it to your local vacuum repair shop and they should be able to fix it for a nominal fee.

Central vac our central vac will not work unless the main vac in the garage is switched on manualy…. its sucking fine but i have to switch it off at the main switch in the garage after i have used it normaly i just plug in the hose and vac away and it switches itself off we have just had cable installed with a fisher guy in the walls do you think that would be the problem thanks a lot
ANSWER : It is possible that the low voltage wiring that controls your central vacuum has been damaged during the cable work. You can check to see if the low voltage relay is working by shorting the two terminals together at the unit. Just disconnect the two small (18-22 gauge) wires from the unit and short across the terminals where the wires connect. If the unit comes on, the vacuum is fine, and it is most likely the low voltage control wires that have been damaged. It should be a pretty easy fix, if you can get to where the wires are located. They are probably just pulled apart at a joint. Good Luck!!

Central Vac will not turn on.
ANSWER : These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.

I have a 3 year old NuTone CV 353W central vac system and recently the switch on the hose handle does not turn the system on from any outlet in the house. I have to plug the hose into the outlet and then turn the unit on from the switch on the cannister. Any help would be greatly appreciated. Thanks
ANSWER : A great way to check if your switch in the hose is bad would be to turn the hose sideways in the inlet. If the unit turns on you most likely need a new switch.

Hoover Windtunnel On/Off switch will not turn Off…Switch seems to work O.K. when pressed directly but not with handle switch…It will turn on but not off..Cam seems to be intact on switch actuator..How does switch come out? Thanx
ANSWER : Take the handle off, then remove the tool holder, then you can get to the switch. Just has tabs on each side of switch, depress them and push it out. These switches will do this after awhile, replacing them is usually the way to correct the problem.

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

ANSWER : 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
