That is error code 104 which is an error with the communication between the display board and the main control board. On your model it can be caused by a faulty drain pump. That is the most likely cause seeing as you had a problem with it draining at first. However, it can be caused by at least 3 other things such as a faulty main control board, faulty RPS or faulty display board. Best to get someone out to test it & diagnose it properly. No point in replacing parts at random.
