Cause:

  • Very dirty window, dirt has not been properly dissolved.

Vacuums

Why does the main filter clog up quickly when picking up fine dust (e.g when working with electric power tools)?

Cause:

  • Filter bag has been forgotten. (Suitability for picking up fine dust is limited when filter bag is not fitted)

Solution:

  • Always fit a filter bag.

Dust is expelled from the vacuum. Why?

Cause:

  • Suction hose is faulty or not properly engaged.
  • Filter missing or faulty.
  • Filter bag has not been fitted.

Solution:

  • Fit a filter bag.

Vacuum cannot be set to stage 2 (automatic on/off facility for electric power tools)

Cause:

  • Stage 2 is designed for operation with electric power tools only.

Solution:

  • The vacuum starts when the electric power tool is switched on. Vacuum continues running for about 15-20 seconds after the electric power tool is switched off and then shuts down.

The vacuum keeps switching itself off.

Cause:

  • Waste container is full.
  • Level sensors and the housing are wet. This can create a damp bridge.

Solution:

  • Empty the waste container.
  • Allow the unit to dry.
  • Clean the level sensors.

Steam Cleaners

Cause:

  • The boiler is still under pressure.

Solution:

  • If the tank cap still cannot be opened, please contact your Kärcher dealer for assistance
