For Bissell CrossWave X7 3011, “Dirty-tank light blinks four times, then stays solid” 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. Bissell's official material anchors this branch with the exact wording “Dirty Water Tank Indicator blinking 4 times, then solid”. 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 “Dirty-tank light blinks four times, then stays solid” 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, remove and empty the dirty-water tank, rinse the float and sensor areas without scratching them, wipe the receiving bay and reinstall the tank until fully seated. Run one short pickup test with no foam. If the exact “Dirty-tank light blinks four times, then stays solid” 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 Bissell 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.
