A CrossWave Cordless Max 2593 leak can be isolated by checking where it starts, then inspecting the clean tank cap and gasket. Separate tank seating, liquid flow, suction and brush drive before ordering a part. Empty dirty water, keep electrical areas dry and run only the short test described for this exact model family. What the alert means: A loose cap, displaced gasket, cracked tank or incomplete seating lets cleaning solution escape before it reaches the floorhead. What to distinguish first: Dry the machine, fill only the clean tank and watch whether liquid appears at the cap, tank seam or receiving valve. 1. Confirm the exact symptom — A loose cap, displaced gasket, cracked tank or incomplete seating lets cleaning solution escape before it reaches the floorhead. 2. Prepare safely — Switch off, unplug the charger and empty both tanks before removing a roller, filter or floorhead cover. 3. Apply the official check — Remove the tank, inspect cap and gasket for deformation, tighten the cap evenly and press the tank down until fully seated. 4. Interpret one retest — Stand the machine on a dry towel for one minute. Replace the official tank assembly if the tank itself still drips. The official Bissell procedure identifies this exact symptom and supports the checks above. Keep the charging port and motor vents dry, and never clear a blockage while the appliance can start. Stop for a damaged tank, battery heat, electrical smell, persistent leak or an error that returns after one clean test.
