Donald for Model Number wf448aap/xaa I keep getting a "ND" no draining error on the washer. I have replaced the whole pump set including the coin basket. Still getting the error code. How do I test the main pcb board to see if it is bad? Should I try changing another sensor first?Thank you, Don
Answer Donald, Check the pressure switch and pressure switch hose. If the hose is clogged and the pressure switch does not reset it will cause this issue. If the unit is not draining then test for 120 vac coming off the main control board to the drain pump. If no power then would be the main board. Read More...
