Dishwasher shows E10 and may not start or may stop shortly after filling.

Safety first: Disconnect power before removing panels.

• Check salt level: Open the salt reservoir cap in the bottom of the tub and ensure it contains dishwasher salt. Top up if empty and wipe away any spilled salt from the tub.
• Inspect for salt bridging: If the salt tank is hard and solid, break up the salt bridge gently with a wooden spoon handle and add fresh salt.
• Run a regeneration cycle: Some Hansa models allow a manual regeneration or intensive program. Run this after refilling salt to reset the system.
• Check softener valve (advanced): Access the side of the dishwasher to locate the softener valve on the water softener tank. Ensure wiring is intact. A failed valve coil will require replacement.

If E10 persists, the softener system or control board may need professional diagnosis.
