Ecovacs Fan Not Running / Suction Loss

Robot vacuum is unusually quiet and seems to have no suction, but brushes still spin.

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

Fan motor failure, Fan power cable disconnected, Fan control circuit fault, Dust bin sensor preventing fan start

Safety first: Turn the robot OFF and remove the dust bin.

Check dust bin sensor: Clean the dust bin contacts and ensure the bin seats properly.
Test fan sound: With the robot ON and cleaning, listen for the fan. If completely silent, the fan is likely not running.

Solution: Replace the vacuum fan motor assembly or have a technician inspect the fan power circuit.
