My washer just stopped within the midddle of its cycle and flash with the code F/02. I lost my instruction book and don't know what to do. Now my clothes sit in nearby with river and detergent. I think F/02 process something. If anyone have this problem in the past, please help me. Thanks.
Answers:    Long Drain

If the drain time exceeds 8 minutes, the sea valves are turned past its sell-by date and "F/02" is flashed.

NOTE: After 4 minutes the "Sud" error will be displayed, then 4 minutes following the F02 error code will be displayed.

Press PAUSE/CANCEL twice to clear the display.

* Check the drain hose and make sure it is not plugged or kinked.
* Check the electrical connections at the pump and variety sure the pump is running.
* Check the drain pump filter for foreign objects.
* If the above does not correct the problem, replace the pump.
