Maytag 2000 series error codes

I have a Maytag Maxima frontload washer that was getting these two error codes. I found in my case it was due to the tub not draining water as quickly expected. On my model there were two screws at the bottom of the front panel (one on each side towards the floor) Once these screws were removed and my husband tilted the washer up I was able to get my hand behind the panel and unscrew the filter cap that is located towards the middle at the bottom. It is a large plastic circle that you unscrew. With your hand remove any gunk or objects blocking the filter (usually filled with gunk) screw the filter cap back in, screw the front panel screws in and try to run another load. I have had to do this twice so far. You would think if the filter needs to be cleaned out every year or so they would make it more easily accessible.
