Samsung Dishwasher: Error Code PE

This code indicates a half-load error code. This code indicates there is an issue with the sump pump, diverter assembly, or motor assembly. It occurs most often when the inner spray arm (which is controlled by the diverter assembly) is not responding. This is most common in the half-load mode. To troubleshoot this issue, you will need to inspect and reconnect any loose wires. You should check for damage and replace all damaged parts.
