stuck in cycle

Model GU2400XTPS1. Dishwasher stopped during cycle, circuit board was burnt and plug was melted (light brown wire). Replaced board, fuse, and repaired plug. Attempted to run a cycle and time advanced to the 63 minute mark and then stuck on 63 minutes. Ran diagnostic test and it indicated the thermistor was bad. Replaced that part, ran diagnostics (all looked good), ran cycle, and still getting stuck on 63 minutes. Any ideas what to look at next?
