Washer displays f09 error

Most times there is something stuck in the drain pump. Take the three lower screws off and remove the panel. Now you will see the pump, unscrew the needle trap on the front of the pump,slowly and have plenty of towels to catch the water and then clean the pump out. After you re-assemble the pump and it is noisy, replace the pump,you might have a broker impellar.Still cheaper then a new washer.
