It is time to get familiar with your appliance! If your Samsung front load or top load washer is displaying the error fault codes 4E or NF, it is important to find out what is going on with your washer. Generally, these error codes mean that you washer is having an issue detecting water.
NF and 4E = No Water Feed = Washer Not Filling
Look for these codes on your control panel display. These indicate that there is something preventing your washer from receiving water into the water inlet valve.
