Commercial washer constantly running

This washer is a Whirlpool coin washer and it is constantly running, I have done a diagnostic test mode and the codes came back to an overflow and over pressure condition. I have checked the drain pump and determined that it is within the correct ohm range of 16-20. The washer was placed in the tachometer mode and it correctly indicated. The washer was also placed in a manual test mode, and each cycle was run. The washer will not enter the heavy agitation cycle. I have some photos and videos and the tech sheet. Has someone also worked with this machine? Would appreciate any guidance here.
