Rectifying Errors

If a fault (e.g. a filter damage) occurs, the vacuum cleaner must be switched off immediately. The fault must be repaired before resuming operation.

Problem	Remedy
Suction turbine will not switch on.	Check the mains cable, mains plug, fuse, socket and fill level sensors (43).
Suction turbine will not switch on.	The main switch (2) is set to "automatic start/stop". Set the main switch (2) to the "extraction" symbol or switch on the power tool plugged into the plug socket (4).
The suction turbine switches off.	During wet extraction, the LED indicators A and M will flash slowly and simultaneously. Empty the container (1).
The suction turbine switches off.	During dry extraction, the LED indicators A and M will flash quickly and simultaneously: The overload protection on the dust extractor socket is activated. Switch off the power tool.
The dust extractor shuts down.	The dust extractor is overloaded due to the maximum voltage of the dust extractor plug socket being exceeded: The motor protection device is triggered. Send the dust extractor to an authorised Bosch after-sales service centre.
The suction turbine will not switch on again after the container has been emptied.	Switch the dust extractor off and wait 5 s before switching it back on.
	Clean the fill level sensors (43) and the space between the fill level sensors (43) using a brush.
The suction power is decreasing.	Remove any blockages from the vacuum nozzle, suction tube, vacuum hose (30) or flat-pleated filter (34).
	Change the fleece filter bag (33).
	Make sure the filter cover (40) is engaged correctly.
	Place the top part of the vacuum cleaner (16) on correctly and close the catches (19).
	Clean or change the flat-pleated filter (34).
Dust is escaping during extraction	Check that the flat-pleated filter (34) has been fitted correctly.
Dust is escaping during extraction	Clean or change the flat-pleated filter (34).
Automatic switch-off (wet extraction) is not working.	Clean the fill level sensors (43) and the space between the fill level sensors (43) using a cloth.
Automatic switch-off (wet extraction) is not working.	Check the fill level regularly.
Acoustic warning signal sounds.	Suction power setting too low. Set the suction power regulator (11) to a higher setting.
	Hose diameter setting is wrong. Set the correct vacuum hose diameter.
	Vacuum hose (30) is blocked or twisted. Remove blockage or untwist hose.
	Fleece filter bag full Change the fleece filter bag (33).
	Flat-pleated filter (34) is dirty. Clean or change the flat-pleated filter if required.
	The airflow supplied by the connected power tool is insufficient Open the false air intake on the power tool if there is one or use a suitable dust extraction adapter with a false air intake.
	Malfunction of the monitoring electronics Contact an authorised Bosch after-sales service centre.
Acoustic warning signal sounds during wet extraction.	No measures necessary.
The automatic filter cleaning function is not working.	The automatic filter cleaning function only activates when the airflow drops below a specific level. To check the filter is working or to manually clean the filter, switch to manual mode by pressing the manual filter cleaning button (9).
Manual filter cleaning cannot be triggered.	Over-temperature protection of the dust extractor is activated. Pressing the manual filter cleaning button (9) continuously ten times has triggered the over-temperature protection. The over-temperature protection will be automatically suspended after 20 s. Pressing the manual filter cleaning button (9) continuously 30 times has triggered the over-temperature protection. The over-temperature protection will be automatically suspended after 4 min. If the problem persists, contact an authorised Bosch after-sales service centre.
