Hello - I removed and checked hoses for blockages - dollar coin was removed. I reassembled everything and still got the "ND" status. I bought a new pump and replaced - still "ND" Disconnected the wiring harness to the pump. Started the spin cycle. Measured between 12-14V (AC). What should be traveling through those wires? What should I try next? many many thanks. Peter

Hi Everyone. First I want to say thank you for all the material and help I've already gotten; this is a great site. Second the reason I am posting here is to beg for a Samsung WF337AAG/XAA Service Manual. I currently have a nd error (No Drain). Thanks to this site and others I knew enough to check all the hoses and the Drain Pump. They are clear; I even took the pump apart and cleaned out even the smallest amount of "gunk." This unit was made in 2007 so there is no up front filter and the Drain Pump is also in the back.... currently easy to get to at least. Anyway, I bench tested the pump by applying 120v directly to the terminals and the pump runs like a champ. When I test the plug that connects tot he pump I don't get much in the way of voltage.. assuming I'm doing the Drain test propertly. Btw, I'm doing that by pressing "Spin + silvercare and Power" at the same time. After it displays the software version I select "Soil" My understanding is that, that should make the pump come on... it doesn't and I have no voltage down the line. SO, all this leads me to believe that I've either got an expensive PCB issue or cheap wiring issue. I would LOVE to check the pins on the board that activate the drain pump but I don't know where they are... I did find a manual that is iffy and it suggested pin1 on CN5 and Pin6 on CN10... I did find CN5 and CN10 but I'm not sure which pins are which.. that part was in Japanese. *shrug* So in conclusion please please please, oh great master please, allow me to look upon the great scroll that is the Samsung WF337AAG/XAA Service Manual. And also.. if anyone has any advice or help they could give me (especial in the way of the pin outs) I'd really appreciate the help. OH, I'm attaching a picture of the control board below! Thank you, Cory
