Product review (5 stars): Fix 1E error code, diy
Spent a couple of weeks with my 2 year old Samsung dishwasher sometimes working and sometimes throwing a 1E error code.  After a little research I found that I could fix the issue with a simple sensor replacement.  After almost 3 months we have not have another issue.

Pretty simple to replace on my Samsung DW80F800UWS :
 - Remove dishwasher form under counter,
 - Flip over and remove cover on bottom
 - Sensor and connector should be clearly visible
 - Twist to remove sensor and disconnect wire connector
 - Insert new sensor and twist to seat
 - Reconnect wire connector
 - Replace bottom cover
 - Reinstall underneath counter
