Susan J. for Model Number NFW7200TW Amana I am getting the error code ND (no drain.) I unplugged it, checked the drain pipe to make sure it wasn't clogged or pinched. I plugged it in, then turned the power on, and press the rinse and spin cycle only button. It worked. The next load went through the entire wash cycle. Then the ND error code started again and hitting the rinse and spin cycle only worked for a few more loads. Now the ND error code occurred on the rinse and spin cycle only. I turned it off and unplugged it, waited an hour, plugged it in, turned it on, and pressed spin only. It drained and spun as usual. I couldn't find any solutions/answers about this issue. Does this problem occur when a pump is going out?
Answer Susan, It doesn't sound like a drain pump problem, at this point. The control board is "looking" for the pressure switch WP34001324 to reset to the empty mode/circuit within a few minutes from the start of the drain cycle. If the control doesn't see the change in the circuit, it can produce the "ND" code. First, disconnect the pressure hose 34001436 from the pressure switch and blow in the end of the hose, this will usually clear any debris or sediment that may have developed in the tube. Also check and make sure the hose isn't twisted or kinked, that can restrict the air flow. If the "ND" code persists check or replace the pressure switch. The main control board should be the last resort if the problem persists. Read More... Answered by AppliancePartsPros.com | Monday, July 20, 2015
