not sure if my washer is fully completing the cycles

Thanks for the head up...I was able to get my whirlpool dishwasher in diagnostic mode thinking that would reset. I don't understand how to see and understand the codes anyways (even looked at the tech guide) but don't think that's my problem. Now my problem...if you or anyone sees this post...is that I'm not sure if my washer is fully completing the cycles, since I don't get the clean light on even though all appears to be clean. Also, which is what made me start to look into this, the start/resume light never goes on, even when running or if I open during a cycle....but the washer seems to work anyways. One thing I did notice putting the washer in diagnostic mode (the 123...thing), all lights, even the clean light, go on, except the start/resume light. Any thoughts...could that light or connection just be out, or should a reset (turning off the circuit braker?) be done and could address?
