• Check salt level: Open the salt reservoir and refill with dishwasher salt if empty. Wipe away any spilled salt.
• Adjust softener: Set the water softener level according to local water hardness as per the manual.

• Use descaler: Run a maintenance cycle with a commercial dishwasher descaler to remove existing limescale.
