The bottom of the unit keeps coming unattached from the rest of it. Happens repeatedly. Why??

things you will need Vacuum belt

• Screwdriver

1. Locate and purchase the correct belt for your Eureka vacuum cleaner from the local grocery or department store. Vacuum belts come in different sizes according to your model of vacuum. Check your owner's manual or the vacuum itself for your model number.
   

2. Turn your vacuum cleaner over so that the bottom of the unit is facing you. Remove the cover plate from the bottom by undoing the screws that are holding it in place with a screwdriver.
   

3. Locate the belt pulley rod near the back of the vacuum base coming out of the motor. With the vacuum cleaner base turned upside down and facing you, the motor and pulley rod should be up near the top of the base.
   

4. Slide the vacuum brush roller out of the slots at the bottom of the vacuum base and remove the old belt from the brush roller and pulley rod. With the brush roller off of the unit, clean the brush by removing any strings or cords wrapped around the tube.
   

5. Install the new belt by looping it over the belt pulley rod next to the motor and then looping around the end of the brush roller in the belt slot. Hold the brush roller and pull back on it to tighten the belt while you slide the roller back into the slots on the vacuum base.
   

6. Replace the base cover plate by snapping it back into place and securing it with screws. Turn vacuum back upright and turn it on to test the belt and verify the unit is working
   

Double check the elbow at the base on the right hand side (back facing you) of the vacuum for clogging.

Many times it will appear free but be packed solid at the elbow just out of sight, there should be a screw on lower right that when removed will detach let you detach the elbow from the base of the plastic tube that holds the upper attachment hose this will help you straighten it bit to free any clogging, remove the beater bar & belt, apply suction with a shop vac or another vacuum to the front tube just behind the beater bar, you should feel suction at the elbow where you detached it if it's clear. If not you may need a stiff piece of wire or something similiar to help carefully clear it out.

I've worked on many of these and they somehow seem notorious for clogging in that particular spot.

It could be one of several problems.
1. Ensure the filter is clean. It should be rinsed and dried thoroughly about every six months. Allowing it to go longer results in dirty filter, which results in excessive stain on the motor, which will eventually cause the motor to burn out. I highly recommend keeping an extra filter on hand to use while the other is drying.
2. Ensure filter is in the vacuum and properly seated. There's a cut-off switch above the filter that prevents the vacuum from working if there is no filter. This is to prevent dirt and debris from being soaked into the motor compartment and thus into the motor.
3. Detach the low voltage wiring from side of unit. Use a pair of needle nose pliers to short across the terminals of the vacuum. If the motor and CVA board are good the vacuum should run. If it doesn't, the problem is with the motor or CVA. Further trouble-shooting to determine the problem should be done at an authorized Aerus Electrolux store by a trained technician.
4. Any broken or worn out switches, wiring, and/or terminals in vacuum unit or hose/attachments could also result in the machine not working. This is assuming you have the deluxe set of attachments with the electric hose and power nozzle.
Testing hose: Detach hose from wall and wand. Turn switch full on. Using a continuity tester or multimeter, place one lead in a terminal on the hose, and the other lead to each lead on the other end of the hose. One lead should read zero, the other infinity. Repeat with the other terminal. The readings on the other end of the hose should be opposite of the first lead. If any of the reading are other than this, the hose needs to be repaired or replaced.
Any problem can be easily diagnosed at an authorized Aerus Electrolux store. You'll need to take the unit, hose, wands, and power nozzle to the shop for accurate diagnosis.

1. Detach the hose and turn on. If it runs, place hand over opening. If it shuts off, the control valve assembly is dirty or worn out and needs cleaned/replaced. This is a job that should be done by an authorized Aerus Electrolux service tech. It's most commonly caused by use of "made-to-fit Electrolux" bags, rather than the genuine bags made by Home Solutions.

2. If the vacuum keeps running after detaching hose and placing hand over in port, then check the hose. Drop a coin or similar small item through the hose. If it doesn't go through, there's a clog. It will probably be at the bend of the handle. Plug hose into exhaust port and turn vacuum on. Make sure the other end of the hose is in a bag to catch the dirt and stuff coming out. If you have problems, it's easily removed by a service tech.

Make sure there is liquid in both the Tank-in-Tank and the SmartMix Bottle and check for spray through the upholstery hose. If the hose does not spray please check the following:

- Remove the belt access door and inspect the pump belt to ensure it is not broken, worn or stretched. You may also check the belt by turning on the power and watching the brush on the bottom of the machine. If the brush rotates the belt is not broken.

- Check for proper placement of the o-ring on the SmartMix Cap Insert (some o-rings are detachable and need to fit over the straw; others are molded to the cap).

- Check for liquid in the base of the machine where the SmartMix Bottle sits (SmartMix Reservoir). If there is no liquid in the reservoir, the neck on the SmartMix Bottle may be undersized, the cap will not make proper contact with the unit and the smart mix bottle will need to be replaced.

- Check for the black or red tank gasket on the SmartMix Bottle Cap and on the bottom of the Tank-in-Tank Assembly. If gasket is lodged in base of unit or has been lost, reattach gasket on auto-load or order new gasket if appropriate.

- Check the valves on the bottoms of the Tank-in-Tank and SmartMix Bottle to make sure water/solution will come through when the "x" valve is depressed. Bladder or SmartMix bottle may be empty or the valve may be blocked internally.

- Check if the small rounded window tabs on the top edge of the Floor Nozzle Window are locked in their mating slots on the base of the machine and not inadvertently lifting the tank up out of place.

Sounds like poor electrical contact between the base and the bag compartment. If you separate the base from the bag compartment (press the button at bottom front of bag compartment, then pull or lever the two apart) you will see the electrical contacts - they may need cleaning, or perhaps bending VERY SLIGHTLY to help make proper contact. Otherwise, something in that same area may be damaged and need repair. Good luck!

If that condition is present when the unit is not turned on, or not plugged in, then the failure is a water control valve (solenoid), located in the base. It may be stuck open, or have debris blocking the seal internally. The valve itself is not user serviced.

machine will not come on

The screw that is located in the center of the handle, that holds the assecory hose holder must be tight. My screw was missing, put one in and cured the problem. Sounds stupid but it worked. Got this idea off the Bissell web site. Also if you have a pump belt it may need replacing.The cover is on the side of the machine. Go to the Bissell web site and look up by your model # and name of machine. There are several quick fixes that you can do yourself. Why pay for expensive repairs when the Bissell site will help you for free. Good luck.

There should be a bottom plate covering the brush roll that you can remove, if you can't dig out the what is in there, try using your hose and suck it out from the bottom, maybe you will be able to get it out.
