Dishwasher shows E10 and does not start the wash; sometimes accompanied by unusual noises from the motor area.

Safety first: Disconnect mains power before accessing the base of the dishwasher.

• Listen for motor attempt: Start a cycle and listen. A brief hum followed by E10 suggests the motor is trying but cannot start.
• Check for mechanical blockage: Remove filters and inspect the sump for foreign objects. Access the circulation pump from the base and check that the impeller turns freely.
• Inspect capacitor: Many Becken circulation pumps use a start capacitor mounted nearby. Check for bulging, cracks, or leakage. Replace if suspect.
• Electrical test: With the appliance unplugged, measure motor winding resistance. An open circuit indicates a failed motor.
• Control board: If motor and capacitor are good, the control board’s motor drive circuit (triac/relay) may be defective and require board replacement.

Due to the need for electrical testing and possible board work, this repair is best handled by a technician.
