Do-It-Yourself Story

Error Code F/H. The hot water inlet valve had black deposits in the screen that were difficult to remove. The black deposits were obviously slowing the hot water flow down to a trickle. Replaced the inlet valve assembly - problem solved. Error Code F/dU. At random times the door would not unlock. I had to remove the toe panel and reach up to manually pull the door unlock tab. A new door switch assembly appears to have solved the issue.
