I'm sorry to hear you're having this issue. The "nd" code indicates your WF337 is not draining properly, which is likely a result of a clog or partial clog in the drain hose. Before calling for service, check the following:
1) Turn off the unit and turn it on again.
2) Select only the Spin Cycle.
3) Press the Start/Pause button to drain the water.
If it still does not drain, your washer will require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
