TwinDos draws detergent from two cartridges through dedicated lines, and on the WWH660WCS the behavior to understand is what happens when a cartridge is allowed to empty completely. Air gets into the line, and simply fitting a fresh cartridge does not always clear it – the system needs to prime. Owners who replace a cartridge and still get no detergent are usually looking at an air lock rather than a pump failure.
