How to Identify and Fix Common Vacuum Problems ?

If the unit runs for a few minutes then shuts off, the motor needs to be replaced. Central vacuum motors generally last for 800-1100 working hours. If your motor has run less than 800 hours or activates by jolting the canister, it may be possible to extend the life of the motor by replacing the carbon motor brushes.
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.
Filters must be cleaned regularly. If they become blocked, the overheat cut-out device may activate. If the vacuum cleaner cuts out: STEP I: Switch it off and allow it to cool for 1 hour. STEP 2: Empty the dust container and clean the filters.
Overheating usually occurs because the dust bag has not been emptied, filter has not been cleaned or there is a blockage in the floor tool, wand or bent hand piece. If your vacuum shuts down unexpectedly, make sure you turn the vacuum off and unplug it from the wall socket.
Putting in the incorrect amount of oil, putting in the wrong type of oil, and oil contamination can all cause the pump to not reach full vacuum. For this reason, you must check the oil regularly to ensure that it is not only clean, but also properly filled.

How long does a central vacuum system last? A central vacuum unit can easily last 20 years. The life expectancy of a hose, carpet brush and attachments varies depending upon use.
The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
The vacuum has a safety feature that turns off the vacuum when the vacuum gets to a certain high temperature or overheats. This happens because the vacuum has a motor protective thermostat. If the vacuum turns off due to overheating, the thermostat has to be reset before you can use it again.
Vacuum cleaners are often designed to turn themselves off if they hit a thermal cut-off point. Basically, if the machine is starting to overheat, there is an automatic system in place to prevent damage to your vacuum or other issues. The most common cause of overheating is blockage.
Insufficient suction pressure.
Low pressure at the pump inlet can cause cavitation, which occurs when the liquid entering the impeller eye drops below its liquid vapor pressure and vaporizes to form bubbles. Vapor in the impeller saps pump performance.

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly
ANSWER : The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

While vacuuming the red light for the bag of the vacuum came on and the vacuum stopped. The bag was no where near full so I replaced it with a new bag – same problem. It vaccumes for a minute or then stops with bag light on. It is the correct bag for the machine – so what’s the problem?
ANSWER : I’m assuming this is the Epic 6500 or similar model.
.Detach the hose, turn vacuum on. If it runs, place palm of hand against inport hole. If it shuts off the problem is with either the control valve setting or the control valve assembly itself.
.For cvs, turn dial on top of vacuum all the way to the largest dot, and try above test again. If that doesn’t work, then it’s the CVA. It needs to be cleaned or replaced, which is an in shop job. Fro repair, take it to the nearest Aerus Electrolux store. I recommend a full clean and service to remove any dust/dirt from the motor, fan assembly, and other internal parts.
.
.Another problem, which relates to the dial setting, is that fine dust will quickly clog the pores of the bag, resulting in the machine “thinking” the bag is full. Turning the dial to the proper setting helps get the bag fuller. The middle setting is the normal setting, and is for areas without fine dust and sand.

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.
.This is where a vacuum that won’t run without a bag would have been nice. (Aerus for one)

My home has a central vacuum system hook-up but no vacuum installed. My friend upgraded his central system and gave me his Eureka Mega Boss central vacuum system and the accessories, including the pow
ANSWER : The power head requires 120 Volts. Some hoses have a receptacle in the handle for the power head plug, and the hose has a cord at the wall inlet end that plugs into a receptacle. Some hoses have a plug at the wall inlet end that plugs into a 120Volt receptacle built into the inlet. The hose plugs into this receptacle when you push the hose into the inlet. The power for this built-in receptacle is wired with line voltage when the system is installed.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor, not contacting the carpeting?? I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting. Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

Won’t start. My son was using the vacuum & Didn’t change the bag. The vacuum was making the full bag smell, but the light was’t on & it didn’t stop. I stopped him, changed the bag, checked the filter, closed the compartments & turned on the vacuum. Nothing happened. I checked to be sure that it was plugged in, that wasn’t the problem. I’ve let the vacuum “rest” for several days, It still won’t start. Any suggestions?
ANSWER : There is a reset button at the back of the powerhead. The user manual can be downloaded from the electrolux website, although I didn’t find it very useful. There was some info on how to change the powerhead drive belt.
