Makita Trigger Latch / Control Logic Fault

Vacuum continues to run briefly after releasing the trigger (more than the normal soft-stop).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Sticky trigger mechanism, Faulty trigger switch contacts, Control PCB not detecting trigger release promptly, Moisture or contamination inside handle

Safety first: Remove the battery before cleaning.

Clean around trigger: Use a dry brush or compressed air to remove dust from the trigger area.
Check trigger movement: Ensure the trigger returns quickly and fully when released. If it feels sticky, internal cleaning or replacement may be needed.
Allow to dry: If the vacuum was exposed to moisture, allow it to dry in a warm, dry place for 24–48 hours before further use.
If behavior persists: The trigger switch or control PCB may be faulty and should be inspected and replaced by a technician.
