Cordless stick vacuum shows F1 on the small display; suction stops, but lights remain on.

Safety first: Remove the battery before adjusting the bin.

Steps:

• Remove and refit bin: Detach the dust container completely, check for debris around the mounting rails and latch, then refit it until it clicks firmly into place.
• Inspect latch: Ensure the bin latch is not cracked or deformed. A loose latch may not actuate the internal microswitch.
• Check bin door: Make sure the bottom flap is fully closed and latched; some models will not run if the flap is open.
• Test switch action: While refitting the bin, listen/feel for a small click from the internal switch. If the bin is secure but F1 remains, the microswitch may be faulty.

Resolution: Replace the dust bin assembly or have the bin microswitch replaced by a technician if it is integrated into the main body.
