My front loading clothes washer. It frequently doesn’t drain right. If you create a fault tree on what causes that, you can have:

• Faulty water level sensor
• Clogged water level sensor hose
• Clogged filter
• Clog around the heating element
• Broken check valve
• Faulty pump
• Clog between drum and liner
• Faulty control board

The pump can clearly be heard running when the water levels are too high, so I know the sensor, sensor hose, controls, check valve, and pump are all functioning. Sometimes, the pump runs for way longer than you’d think necessary, with only a small trickle of water coming out little bit by bit. This indicates to me that there is a clog upstream from the pump. Multiple times, I have squeezed myself back behind the washer to take the back off and access the filter (which should be accessible from the front). I’ve found no clog there. Ive taken out the heating element to check for clogs around it, and found nothing there. Ive shown a bright light from inside the drum to highlight any potential clogs between it and the drum, and seen nothing there. Despite all of that, the problem remains, and when I manually spin the drum with nothing inside, I can hear what sounds like stuff moving around inside.

I assume it must be ghosts or something at this point.
