Safety first: Unplug the machine before inspection. Allow hot components to cool.

Allow cooling time: If the unit was used for an extended period, the motor thermal protector may have tripped. Leave the cleaner unplugged for at least 30–45 minutes, then try again.
Check for blockages: A blocked air path can cause the motor to overheat. Remove and inspect the dirty water tank, nozzle, hose, and intake screen for clogs. Clear any debris, hair, or carpet fibers.
Inspect motor wiring: With the housing removed, check the wiring harness from the control board to the suction motor. Ensure all connectors are fully seated and not burnt.
Test motor (advanced): Using a multimeter, check continuity across the motor terminals. An open circuit indicates a failed motor. Replacing the motor assembly is typically required and may be best done by a technician.

If E2 returns immediately after reset and cleaning, the motor or control board is likely defective and should be professionally serviced.
