I have a he2 kenmore front end loader washing machine...it stops mid load and flashes F20

Something is in your pump trap, easy fix. pop open the bottom panel by removing the three screws under it. requires a torx bit or a nut driver. if you can tilt the washer back so the front legs are a foot or 2 off the ground, it will make this a lot easier. once open you will see a twist off cap. before you remove this be prepared for the residual water to eject out when you open it. these can not get all the water out so there is always some, tilting it back will minimise this or putting hose clamps on the pump to tub hose can help but not nesesarry. twist it out and clean it out, also stick your fing into the two holes where the trap is located to see if any coins have gotten stuck. once clean, make sure you line up the trap arrow with the base. then button it back up, good luck

Before you go tearing anything apart, just try pressing "Stop" and let the washer drain. Then, before running the washer again, make sure it's the only thing using the water (don't run the dishwasher, take a shower, water the lawn, etc...) as F-20 is the code for low or no water pressure. Then add the detergent and run again.
