Hi there, it's Jack at Dyson.

DC28's on/off button will flash to indicate an issue with your machine - it will also shut the brush bar off for protection. To check the cleaner head and brush bar for any issues, please follow the steps shown in our video guide. It's important to ensure there are no obstructions in the cleaner head, and that the brush bar is free of any threads or hair:


Once you've done this, you should find the issue is resolved. It's important to note the brush bar will never rotate when the machine is standing upright, so recline it into the normal vacuuming position before testing it.

If you continue to have difficulty after giving this a try, please contact us directly so we can provide further assistance. DC28's cleaner head is a complex assembly and the brush bar isn't designed to be removed by the user. Attempting to repair it could cause damage, and may void any remaining Dyson warranty coverage on your machine.

You can reach the Dyson Support team by calling 1-866-693-9766 (US), or 1-877-397-6622 (CA).

See if the following information can help.

CARPETS OR HARD FLOORS

• The brush bar will always default to 'ON' (spinning) each time you switch the

appliance 'ON' and recline it for cleaning.

• The brush bar will not rotate when the appliance is upright.

• To switch the brush bar 'OFF' (e.g. for delicate rugs and hard floors):

- switch the appliance 'ON'

- recline the appliance

- press the brush bar 'ON/OFF' button - the brush bar will stop spinning.

• The brush bar will automatically stop if it becomes obstructed. See 'Brush bar -

clearing obstructions'.

• Before vacuuming your flooring, rugs and carpets, check the manufacturer's

recommended cleaning instructions.

• Some carpets may fuzz if a rotating brush bar is used when vacuuming. If this

happens, we recommend vacuuming in 'hard floor' mode and consulting with

the flooring manufacturer.

• The brush bar on the appliance may damage some carpet types. If you are
unsure, turn 'OFF' the brush bar.

The horrible noise may be something wrong in the brush bar assembly preventing the brush bar from spinning freely. Remove and inspect the brush bar and belt or belts if applicable to your model.

Greetings from GoVacuum,

It sounds like you have a bad part called the Clutch Rubber Pad Holder Assembly on the inside of your roller brush. I believe that the problem you are having is that the roller brush does not spin, but the belt is properly installed and engaged, correct? This can only be something inside the clutch mechanism in the roller brush itself has gone bad. The easiest way to fix this is to purchase a new roller brush assembly, which can be purchased here; Riccar 8000 Series Roller Brush With Rug/Floor Switch. I realize that this is a rather expensive part at $43.00, but it may be worth it for you to avoid the aggravation of having to take apart the roller brush piece by piece. To test out this part, and verify that it has gone bad what you need to do is turn the vacuum upside down and remove the bottom plate. Then make sure the vacuum is in the Carpet setting on the Rug / Floor switch on the top of the vacuum. Now while the bottom plate is off, turn the vacuum cleaner on. Can you see the belt spinning on the brush? Is the brush roll itself not spinning? If the belt is spinning on the pulley, but the brush itself is not spinning, this indicates that it's bad.

If you decide that you'd rather just replace the rubber gasket inside of the roller brush, here's a detailed repair solution for you on how to replace this part;

Step 1: Remove the roller brush from the vacuum cleaner completely. If you need help with this step, please see my repair solution for the belt change on your model here; http://www.fixya.com/support/t4184186-replace_belt_riccar

Step 2: Once the roller brush has been removed, turn the brush on it's side, so the metal end that has 2 teeth protruding out is on top, and the end that has the rubber cap is downwards. Use a flat head screw driver to remove the clip on that outside of the brush;



Step 3: Remove the clip on the outside of the brush with a screw driver, then remove the metal end cap from the brush. The entire roller brush is spring loaded, so you'll need to apply some downward force to these parts so they don't just shoot off. It's really the easiest if you lay out the pieces to the roller brush in the order that they were taken off, to make it easier when you are reinstalling these pieces. After removing the metal cap at the end, this is what you should see:


Step 4: There is a small plastic washer underneath of the metal cap. Remove the washer, and the plastic part underneath of the washer that has two teeth protruding outwards. This is how the brush should look after this step;




Step 5: After removing the plastic part with the teeth, the next part of the brush is the metal part which is called the Inside Metal Cam. The Inside metal cam is the part that the actuator arm for the rug / floor switch connects into. Remove the Inside Metal Cam from the brush. This is how it should look after this step;



Step 6: The next part underneath of the Inside Metal Cam is called the Agitator Pulley Clutch. This is the part that the belt rides on. Remove the Agitator Pulley Clutch from the roller brush. This is how it should look after the Agitator Pulley Clutch has been removed;



Step 7: The next part that needs to be removed is called the Agitator Compression Spring which is used to spring load the entire roller brush. Simply slide this spring off the Agitator Shaft, and this is how it should look;




Step 8: After the Agitator Compression Spring has been removed, turn the roller brush on the side, and remove the Agitator Shaft from the roller brush. This is done by simply pulling the other side of the brush end which is covered by a rubber boot. This will remove the long metal shaft which is sticking up. This is how it pulls out;



After the shaft has been removed, the other end of the brush should look like this;



Step 9: The next part that needs to be removed is probably the part that's worn out on your vacuum. The part is called the Clutch Rubber Pad Holder Assembly, Riccar Part Number C012-0400. The way the roller brush works is, when you move the Rug / Floor switch to Floors, the clutch (the parts that you just took apart) loosens up so that the belt is still turning, but the pulley that it spins on is not tight against the brush. When you select the switch to carpets, the clutch then tightens the pulley against the Clutch Rubber Pad Holder Assembly so the when the belt spins on the pulley, it's also now going to spin the brush. Over time this part gets heated up, and the rubber wears down to a point where the pulley will no longer stick to it, which causes the exact problem that you have, where the belt is installed correctly, but will not spin the brush. Simply use a flat head screw driver and pry directly on top of the brush strip, and remove the Clutch Rubber Pad Holder Assembly;

This is how the part looks by itself; If you're interested in purchasing this part, you may contact your local Riccar dealer, or we can also supply you this part.

The bearing is bad on the end that turns hard. You will need to purchase a new brush roll assembly. If the roller is older that 4 or 5 years, it should be changed anyway. The brush strips that scrub the carpet loose their strength after many years of combing through the carpet, so it's a good idea to change it every 5 years or so.

You really need to take the sole plate back off and make sure the belt is running exactly where it's supposed to go and not looped over a piece of plastic or anything. More important is that you make sure the ends of the brush are seated properly and the bearings the brush is mounted to are clean and rotate freely. Look at each component and make sure they are assembled perfectly. Make sure a plastic ring or piece that goes on the end of the brush didn't get dropped under a piece of furniture and you forgot about it. If the problem keeps happening, take the brush and belt back out and carefully turn the machine on to see if it makes the sound. If it doesn't make the sound with the brush out, the problem is with the brush assembly. If it does make the sound, the clutch that turn the brush on and off is damaged and needs to be replaced. You can order a new clutch assembly and replace it without much trouble. They want you to think you can switch between floor and carpet settings all the time but it's really really stressful on that clutch to switch between settings with the motor running. Think about how powerful that motor is. Think about the poor unassuming brush assembly being jerked to life by that powerful motor running at full speed. I've seen that destroy a clutch in about two years. Anyway, it's much better for the life of your dyson to turn the motor off when you switch to carpet mode (when you turn the brushes on). You probably don't have to bother turning off the motor when turning the brushes off, or switching to bare floor mode, because it's not that stressful on the mechanism to just disengage the running motor.

You need to clean your roller and replace the clutch assembly that drives the belts. poorly designed vacuum with many flaws.

This is over a year too late, but perhaps this will help other people in your situation. Here is how the switch assembly should go together:

Stand vacuum up and with it plugged in. Rotate knob between carpet and bare floor and back 5 times leaving it on carpet when finished. Rotate vacuum back from upright position and lay vacuum on the floor, rotating it onto its side. Turn vacuum on.
