I have problems with my Dyson DC04

Reported Dyson DC04 Issues

Less than normal or has no pickup from the Dyson DC04  head or the Machine is turned off in use

Solution:

  • If vacuuming non-delicate carpeting, ensure brush control is set on carpets mode. Note: The brushbar will only spin when the handle is reclined
  • Remove and check the washable filter to see if it is clean (the filter should be blue in color). Wash filter if necessary as shown on page 8.
  • If you removed the soleplate, it must be refitted flush with the cleanerhead. If it is not, refit the soleplate as shown on page 15 and re-check performance.
  • Be sure the filter housing, U-bend, and airway inspection valve are snapped in securely, and confirm there are no blockages

The Dyson DC04 has Less than normal or no suction from the wand or hose

Solution:

  • Confirm the U-bend is in place and that there are no blockages
  • Remove the wand and check for blockages.
  • Confirm the hose has no blockages or holes by stretching it out.
  • Be sure the filter housing and airway inspection valve are snapped in securely and confirm there are no blockages.
  • Remove and check the washable filter to see if it is clean (the filter should be blue in color). Wash filter if necessary

The Dyson DC04 Brush bar not spinning

Solution:

  • Ensure brush control is set on carpets mode.
    Note: The brushbar will only spin when the handle is reclined.

A loud ‘ratcheting’ noise coming from the Dyson DC04 head when vacuuming

Solution:

  • Ratcheting may indicate there is an obstruction in the brushbar and is meant to protect the belt in the machine. Note: the ratcheting may also occur if your carpet is not adequately attached to the floor or if your rug has loose tassels. (This noise does not hurt the machine.)
  • Check to see if there is an obstruction in the brushbar as shown on page 15.
  • Note: when refitting the soleplate it must be fitted securely. Affix as shown on page 15.
  • If there is no obstruction, you may want to set brush control to bare floors mode.

The Dyson DC04 will not stand upright

Solution:

  • Stand behind the vacuum holding the handle at a 45-degree angle.
  • Locate and remove the airway inspection valve and take note of the square plastic molding where the airway inspection valve plugs into. (It should slide up and down.)
  • Snap that square plastic piece up toward the ceiling.
  • After it snaps into place, the unit will stand upright.
