Dishwasher displays E13 and may stop with water remaining in the tub or unusual level behavior.

Safety first: Unplug the dishwasher and close the water tap.

• Access base tray: Remove the lower front panel and, if necessary, tilt the dishwasher slightly to view the base area.
• Locate secondary float: Some Hansa models use an additional float or sensor in the sump or side chamber. Ensure it moves freely and is not obstructed by food residues.
• Clean float area: Wipe away grease, detergent residue, and debris from around the float and its guide.
• Check wiring: Inspect the sensor wiring harness for damage or loose connectors.

After cleaning and reseating connectors, run a test cycle. If E13 persists, the float sensor or control board likely needs replacement.
