my bosch exxcel 1600 express is bringing up the error code?

My machine doesn't drain then error code FO4 flashes up. Ive emptied all the water out manually and have unscrewed the filter and have found nothing. It still wont drain - what else could it be ?

F04 error code means a blockage in your drainage system. If you open the access panel on the front at the bottom of your washer and unscrew the cap you will probably find coins or other foriegn objects in there.This should solve your problem.
