Machine has filled past normal level on a few occasions. I get nd (no drain) and nf (no fill) codes. On some attempts to wash, the machine makes a pump out sound several times and does not start a cycle. I just ran an entire load without a problem. The next wash, I might get to the wash drain cycle and get the nd code. I shut it off and start over and it works fine. Help Please!!!
