White film or cloudy deposits on glassware and dishes after washing.

Safety first: No internal electrical work is required for this issue.

• Check and refill salt: Fill the salt reservoir with dishwasher salt and ensure the cap is tight.
• Set water hardness: Adjust the Iberna dishwasher’s hardness setting according to your local water hardness (see manual).
• Adjust detergent and rinse aid: Use the recommended amount of detergent and increase rinse aid dosage if spotting persists.
• Descale the machine: Run a hot cycle with a dishwasher descaler to remove existing limescale from internal parts.

Proper softening and dosing should restore clear glassware.
