Dishwasher shows E14 and may not complete the cycle, often with irregular water levels.

Safety first: Unplug the dishwasher and close the water supply.

• Bleed air from system: Disconnect and reconnect the inlet hose, then run a short cycle to ensure there is no trapped air causing erratic flow readings.
• Clean water matrix: Remove the side panel and inspect the plastic water matrix for heavy limescale or sludge. Flush with hot water and descaler until channels are clear.
• Check flow meter wiring: Ensure the flow meter connector is secure and wires are not damaged.
• Factory reset (if available): Some Iberna models allow a reset of water intake calibration via a service program. Refer to service documentation or consult a technician.

Persistent E14 usually indicates a failing flow meter or control board that should be replaced.
