Low solution level error even with full clean water tank

Safety: Disconnect from mains before inspection.

• Re-seat the tank: Remove and firmly reinstall the clean water tank, ensuring it clicks into place and the bottom valve opens.
• Check tank magnet (if used): Some Miele tanks use a small magnet to signal presence. Verify the magnet is still in place and not dislodged.
• Inspect chassis sensor: Locate the reed switch or microswitch under the tank area. Ensure it is not bent, damaged, or obstructed.
• Test with gentle pressure: With the unit unplugged, press the switch manually and listen/feel for a click. If no click or if it feels loose, the switch may be defective.
• Replace faulty sensor: If the tank and magnet are intact but the unit still reports low level, replace the tank presence/level sensor.
