Sencor Thermal or Overcurrent Protection Triggering

Vacuum turns on but shuts off after a few seconds without any error code.

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

Blocked filters causing high load, Failing main motor in Sencor unit, Loose battery connection causing voltage drop, Partially shorted wiring harness

Safety first: Remove the battery before inspection.

Clean and inspect: Empty the dust bin, clean all filters, and check for blockages in the wand and nozzle.
Check battery fit: Ensure the battery locks firmly and does not wobble.
Test without attachments: Run the vacuum with no wand or nozzle attached. If it stays on longer, the problem is in the attachments.
Motor health: If the unit still shuts off quickly with clear airflow, the motor may be overheating or drawing too much current and should be replaced.
