4E Error Code

Hello,

This thing has us stumped. The dishwasher will not fill with water and throws a 4E error code. After researching this we found that float switch assembly, float sensor, and or water inlet valve to be the main culprit. We have replaced all of these parts and have not found resolve. We also disconnected the water hose (to reset the built in sensor) with no luck. We have cut power to the circuit breaker too. This thing is an anomaly. Any help or suggestions would be greatly appreciated. Thanks!
