Introdução
Use this guide to pull stored error codes and run built-in tests on a Samsung front-load washer with the WF42H* style control panel. These diagnostic features can help you narrow problems down to areas like wiring, the door lock, the drain pump, the water valves, or the control board before you start replacing parts.
The code list starts around the five minute mark, and includes:
- Samsung Washer 1E Code
- Samsung Washer 3E Code
- Samsung Washer E3 Code
- Samsung Washer NF Code
- Samsung Washer ND Code
- Samsung Washer AE Code
- Samsung Washer DS Code
- Samsung Washer DL Code
- Samsung Washer LO Code
- Samsung Washer HR Code
- Samsung Washer OE Code
