Washer shows E17; drum may rotate erratically or not at all, sometimes accompanied by humming from the motor area.

Safety first: Unplug the washer. Do not repeatedly attempt to start the machine with E17 present.

• Check drum for obstructions: Rotate the drum by hand. If scraping or grinding is felt, inspect the drum holes with a flashlight for trapped objects (e.g., bra wires, screws).
• Listen for bearing noise: Spin the drum quickly by hand. A loud rumble suggests bearing failure, which can overload the motor.
• Inspect motor and wiring: Remove the rear panel, check the motor connector and harness for damage. Smell for burnt insulation.
• Advanced checks: Measure motor winding resistance and insulation (requires appropriate meter). Significant imbalance or short to ground indicates a bad motor.
• Professional service: If bearings or motor windings are faulty, or if the inverter module is suspected, contact a qualified Primus service technician, as these repairs are complex.
