Vacuum trigger or power button is physically stuck or does not spring back.

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

Possible Causes

Debris lodged around button, Broken internal spring, Warped button cap, Liquid spill causing stickiness

Safety first: Remove the battery. Do not spray liquids directly into the button area.

1. Clean around button: Use a dry brush or compressed air to remove dust and debris from around the button.
2. Gently work the button: Press and release repeatedly to see if it frees up.
3. If the button remains stuck or feels loose, the internal mechanism is likely broken. The handle or main body assembly will need professional replacement.
