E14 error with the dishwasher failing to detect water level changes correctly.

Safety first: Disconnect power and shut off water before servicing.

• Locate pressure sensor: Typically mounted on the side of the sump or tub base with a small rubber hose attached.
• Clean pressure hose: Remove the hose from both ends and flush with warm water. Blow through it to ensure it is clear. Reinstall securely.
• Inspect sensor body: Check for cracks, water intrusion, or corrosion at the connector. Replace if damaged.
• Test sensor output: Using a multimeter and Viking service data, measure sensor resistance or voltage at different water levels (this may require service mode). If readings are erratic or out of range, replace the sensor.
• Reset and test: After replacement, clear the error (if your model allows) and run a test cycle to confirm proper operation.
