E06 appears and the machine will not complete a brew cycle; some models may show this after transport or if the machine is tilted.

Safety: Unplug the machine before inspecting internal sensors.

• Check tank seating: Remove and firmly reinsert the water tank. Ensure it clicks or seats fully and that the bottom valve opens.
• Clean tank and float: If your Zwilling tank uses a magnetic float, check that it moves freely. Clean scale or slime with warm soapy water and rinse thoroughly.
• Test with full tank: Fill the tank to the maximum mark and reinstall. Power on and see if E06 clears.
• Inspect sensor area: With the unit unplugged, remove the base or side panel to locate the reed switch or Hall sensor under the tank area. Check for misalignment or physical damage.
• Check magnet presence: Ensure the magnet in the tank or float is still present and not dislodged. If missing, the tank must be replaced.
• Replace faulty sensor: If the reed switch or Hall sensor shows no change when a magnet is brought near (tested with a multimeter or continuity tester), replace the sensor assembly.
