Kärcher FC 7: Automatic shutdown from a full dirty tank or excess foam

For Kärcher FC 7, “Automatic shutdown from a full dirty tank or excess foam” is a distinct manufacturer-documented diagnostic intent. This page preserves the exact code or light pattern, groups every applicable catalog model and limits action to the official safe user check. Kärcher's official material anchors this branch with the exact wording “The device switches off automatically if the waste water tank exceeds a volume of 200 ml.”. That wording identifies the documented condition; it does not by itself prove that a battery, motor, board, sensor, dock or other replaceable component has failed. Keep “Automatic shutdown from a full dirty tank or excess foam” separate from every other alert on the same appliance. Match the full number, colour, flash order, spoken phrase or display text before acting; a different pattern owns a different diagnosis and may have a different stop condition. Switch off, empty and rinse the waste-water tank, clear the level area and refit it correctly. If foam caused an early full indication, use only the specified Kärcher detergent at the documented dose before one short retest. If the exact “Automatic shutdown from a full dirty tank or excess foam” condition clears and the appliance completes one normal start, charge or cleaning cycle, stop the test and monitor it. If it returns unchanged, do not repeat resets or infer a part: record the code, model and serial number for authorised Kärcher support. Switch off and unplug or undock the cleaner before opening a tank, cover or brush area. Wipe spills at once, keep liquids away from charging contacts and never run the machine with a safety cover removed.
