LG LDS4821ST motor sound continously running, no error codes displayed

LDS4821ST Dishwasher has a motor constantly running with no error codes displayed. The problem started after I tried to run a load of dishes before work and came home to the dishwasher sounding like it was still running. I had to disconnect power to get the dishwasher to turn off. If I plug it back in the motor begins to run again. What could be the cause? Bad controller? Bad PCB Assembly?

Serial Number will likely help explain the cause....

The dishwasher is a LG Model #LDS4821ST, S/N 811KWTA00009

Stuck in DRAIN MODE.

Usually caused by oils/fatty deposits from years of washing (contamination) or minerals in the water supply (clay/calcium etc)

Replace the GUIDE ASSY (Part number: 4975DD1001A

Part number: 4975DD1001A)

Located on left side of dishwasher (must be pulled from cabinet/counter for access)

Thank you John63! I will replace the part and let you know. Gotta be cheaper than a new dishwasher, even though the wife will say I am just cheap S.O.B.
