How do I replace the part where the hose snaps into? It's directly behind the switch plate.

Hi Eric,

Thank you for your inquiry. If you are referring to the flexible hose and where it connects to the machine (which is at the base), the entire duct assembly would require replacement. However, if you are referring to the wand handle, and where it connects to the machine behind the power button (or where the hose connects to the wand handle), part replacement is possible.

We would appreciate the opportunity to help you determine which part is necessary to resolve this problem. Please call us directly at 1-866-693-9766 (US) or 0800 298 0298 (UK) so we can provide further assistance.

Best wishes,

The water or solution will not shoot out

Good Afternoon! This is a wonderful machine! Unfortunately, the pumps tend to go out. The pump not only releases the hot water to spray, it also controls the release of the cleaning fluid. Most likely you will need to replace the pump. There is an 800 number on the back at it's base. Serial and model numbers as well. You can test the unit to make sure this is the problem. Fill both the bladder and cleaning fluid resevoir and plug the unit in. Turn it on, release the handle and lower the handle to the floor while it's running. It is safe to do this and the brushes will stop rotating. You will see a hole (opening) in which the fluids normally flow. This hole SHOULD have suction when placing an object directly over the hole. Fingers flattened, a paper plate, anything that is twice the size of the opening and solid enough that it can not be sucked into the unit. If there IS suction, next test is to return the handle to the upright position till it clicks in place. Turn the knob selection from floor to tools. Squeeze the fluid release lever while aiming at a paper plate. See if it has sprayed fluid, then release the handle and try sucking up the fluid. If you again have no fluids released, you do need a pump. Check the age of the unit. Bissell has a 2 year Warrantee that usually covers most repairs and the 800 number will give you local repair shops. If you are out of warrantee, the pump can be ordered and installed through Sears for a reasonable price. Once you do this, YES, purchase their extended warrantee, it always pays off because the pumps go out a lot. But hey...they do a beautiful job cleaning! I hope this is helpful. By the way, if it doesn't pick up fluids, be sure to clean the unit thourally. Take pictures on a cell phone to double check how to put the parts back if you're afraid you won't remember OK?

Water is not coming out when I pull the triger.

If everything is clean, check to see if the water also does not spray from the cleaning tool handle. Most likely your pump needs replacing. I have two of them and pumps go out a lot. To know for sure, fill both the soap and water resevoirs, turn it on, release the handle and lay the handle on the floor. Hold the flat side of a paper plate to the oval hole on the neck opening on the base of the unit located at the back-top, in front of the cleaning solution area. It should **** the paper plate. I just know from going through this for 9 years with two of them. Sears sells extended warrantees even if you didn't buy it there. It pays off in the long run. Beautiful machine. Really works!

Trying to change the belt

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

Dirt devil pool vacuum wont move

If one of these pool cleaners is not working, you likely have an obstruction in the flapper. That would explain why you have suction and no movement. With the pump off, turn the cleaner upside down and check for any twigs, rocks, etc. in the flapper. If you don't see anything or see something you can't reach with your fingers, remove the base plate with a flat head screw driver and check there. The base plate is where the waste is collected.

When machine is running the brush does not turn

You need a new belt. In order to change it, turn the machine compleatly upside down and place the head on a counter, handle on the floor.
There is a L shaped base plate to remove that has 5 screws in. Once the base plate is off, you see the brush roller and a silver shaft directly back from where the belt would ride. Remove the brush roller, place the new belt, Dirt Devil Style 5 ( see link below ) on to the shaft. Then insert the brush roller, so the belt is on the raised carved out section of the brush roller. Grab the brush roller at each end and stretch it till you are able to put the brush roller back into the base. Turn the brush roller backwards 3 compleat turns and the same forward to seat the belt.
Replace the base plate and you're done.

The vacuum fan disintegrated. Unable to determine how to remove the fan from the motor shart.


Follow the steps below gradually:

Remove your vacuum's power head by first switching the carpet height adjuster to its highest setting. Turn the belt lifter, making sure that the two red arrows pictured on the lifter are pointed at each other. Disconnect the head, and take it off.

Remove the bag and handle by first unsnapping the handle by pushing a button on the back of the handle located near the base of the handle. To take off the bag, place your hand on the plastic located at the bottom of the bag, and pull it off.

Remove the metal body by simply unscrewing the four medium-size screws that are now visible because of the power head removal. Once the screws are removed, you can easily lift the metal body right off.

Remove the front fan cover plate using a screwdriver to remove the screws located on the front of the plate. Once they are removed, the fan plate should pull off. If it doesn't, gently pry it off by wedging the screwdriver between the plate and the base.

To remove the fan, clamp a pair of vice grips on the pulley to keep it from moving. Attach a 9 mm end wrench to the motor shaft; this will ensure that the shaft won't spin. Turn the vice grip, which will un-thread the pulley, and pull off the fan.

Integrate the fan, and put the vacuum back together. Plug it in, and test it to make sure it's working properly.

Good luck.

Forward/back cable broke

The cable is user replaceable, but you will need to contact Hoover, or a parts center, to purchase the cable. You will remove the Upper Handle by removing the black screws at the base of the upper handle fit to lower handle (on back).
You will also have to remove the hood to loosen the one screw that holds the cable to the powerdrive gearbox.
