Ron for Model Number wf306bhw/xaa got error code nd, and followed other posts. checked the pump, and it works, and pumps strong when it pumps. hose can be blown through and sucked through, so I assume its fine. Replaced the drain pressure sensor and the washer works just fine, until the 11 minute mark. drains at all the settings, the at 11 minutes it will not drain. if i manually drain it it still will not move forward until it fires the code nd. at that point, i manuially drain it and press start and it caries on, but without draining again. any advice would be so helpful. thank you
Answer Hello Ron, The following is the things listed by Samsung to check for the ND fault code: Will Not Drain • Check for any kink on the drain hose. If any, straight it out. • Check for any restriction in the drain hose. • Close the door and press the Cycle Selector dial. For safety reasons, the washer does not tumble or spin with the door open. • When it is freezing outside, check if it is frozen inside the drain hose. • Check if the water level signal input is correct. Go to Board Input Test Mode. • Go to Quick Test Mode and do Drain Pump Test. • Check if there is any twist in the hose (the one between Tub and Drain Pump). • Check if it reads AC 120V at the pump when a spin cycle is selected. • Read the winding resistance of the pump motor. (14.2 7% Ohms) • Check the pump at CN10 (Pin6) on PCB. It should read AC 110~120V. (Refer to PCB Connector Check) Drain Motor Check: Check Voltage at Pin #1 of CN5 and Pin #6 of CN10 Connections 120VAC from the main board to the pump motor Pump motor resistance Restriction in the pump or drain hose If you continue to have problems, please let us know.
