The f51 error code indicates that there is a problem with the washing machine's drain pump. This error code can be caused by a clog in the drain pump, a problem with the drain pump itself, or a problem with the washing machine's draining system. If the problem is a clog, it may be possible to clear it by unplugging the washing machine and running a vinegar and water solution through the machine's drainage system. If the problem is with the drain pump itself, it may need to be replaced. If the problem is with the washing machine's draining system, it may need to be repaired or replaced.
