Product review (5 stars): Replacing this part solved my "ie"/"1e" errors!
Started receiving error "ie" or "1e", meaning that the washing machine wasn't getting sufficient water. Searching these errors only shows that the water might be shut off or there's a kink in the inlet hose, or possibly a clogged input filter. I had none of those. The washer would initially run fine, and then hit the error about half way through a cycle. Knowing it wasn't external to the washing machine, the inlet valve was the next logical choice. I replaced the cold water inlet valve (and the hot water inlet valve since it's only $11 - part 5220FR2006H) and everything is back to normal. No more errors mid cycle.

This part replaces part number 5221er1003a, which is the same thing.
