Dishwasher shows E11 and may not complete cycles; sometimes associated with erratic filling or draining behaviour.

Safety first: Disconnect the appliance from the mains before accessing the control panel or electronics.

• Power reset: Leave the dishwasher unplugged for at least 10–15 minutes to allow capacitors to discharge, then reconnect and test. This can clear transient faults.
• Access control board: Remove the inner door panel or top cover (depending on model) to reach the main PCB.
• Inspect for damage: Look for burnt components, corrosion, or signs of moisture on the board. If moisture is present, dry gently and identify the source of ingress (e.g., steam leak from door).
• Check connectors: Reseat all multi-pin connectors to ensure good contact. Inspect wiring harnesses for damage.
• Surge protection: If the error followed a power cut or surge, consider using a surge-protected outlet in future.
• Replace PCB if necessary: If visible damage is present or the error persists, the main control board may need replacement with a CDA-compatible PCB. Programming or configuration may be required; this is often best done by a technician.
