Sencor Power Latch / Switch Mechanism Fault

Power button must be held down continuously to keep the vacuum running, or it does not latch on.

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

Stuck or worn power button in Sencor handle, Broken latch mechanism, Faulty electronic latch circuit on PCB, Debris under button cap

Safety first: Remove the battery before working on the handle.

Clean around button: Use a dry brush or compressed air to remove dust around the power button.
Check operation: Press the button repeatedly to see if it regains normal click and latch behavior.
Firmware behavior: Some Sencor models are designed to run only while the trigger is held; verify with the user manual.
Internal repair: If the button should latch but does not, the switch or latch circuit on the PCB may need replacement by a technician.
