Dishwasher stops and shows E6, often without filling or with erratic filling behavior.

Safety first: Unplug the dishwasher before removing any panels.

• Locate the pressure switch: On many Gorenje models it is mounted on the side of the tub or base, connected by a small rubber hose to the sump or air chamber.
• Check the hose: Remove the hose from the switch and the chamber. Rinse it and blow through to ensure it is clear. Replace if brittle or cracked.
• Clean the air chamber: Remove the plastic chamber from the tub wall and wash out grease and limescale deposits that can trap air and give false readings.
• Inspect wiring: Verify that the connector on the pressure switch is firmly seated and that no wires are broken or corroded.
• Advanced test: With a multimeter, check the switch contacts while gently blowing into the hose connection. If the contacts do not change state, the switch is faulty and should be replaced.

If a new pressure switch does not clear E6, the main control board may be misreading the signal and require professional diagnosis.
