Sorry to be so vague but has any one heard of a fault code “SUD” on a samsung washing machine? only info I have is that it is a Diamond model?. Unfortunately this is the only information supplied by WP.
This occurs when too much foaming is detected.
It is also displayed while foaming is removed.
When the removal is finished, the normal cycle
proceeds. “Sud” or “SUdS” is displayed when too
much foaming is detected and “End” is displayed
when the removal of the foaming is finished.
(This is one of the normal operations. It is an error
for preventing non-sensing faults.)
