Product review (3 stars): Loose plug.
Well, after replacing pump I still got E13 error code. Pulled pump, checked on bench pump is fine. Reinstalled and E13 again. Reworked old pump and it work for a couple of loads. Before E13. Reinstalled new pump and discovered that the power plug is not a snug fit. I had to remove plug and put on female connectors on each wire. This fixed my problem. Oh, this drain house was a great addition!
