E10 displayed; salt or rinse aid indicators may behave erratically

Safety first: Unplug the dishwasher before internal inspection.

• Check salt level: Open the salt reservoir in the base of the tub and ensure it is filled with dishwasher salt (not table salt). Wipe away any spilled salt from the tub.
• Inspect for salt bridging: Use a wooden spoon handle to gently break up any hardened salt bridge inside the reservoir.
• Run a regeneration cycle: Start a normal or intensive program to allow the softener to regenerate. Observe if E10 reappears.
• Internal checks: If the error persists, the softener valve or associated flow meter may be defective. These are mounted on or near the side of the tub and connected to the softener tank.
• Professional service: Replacement of the softener valve or tank assembly requires careful sealing and is best performed by a technician.
