Jeffrey S Sugar Land , TX September 26, 2021 Ul error code f51 error code. Looked up the error codes, ordered the parts, watched the video tutorials, while I changed out the parts, I kept the video close by for reference. I buttoned it back up, ran the washer for a couple of cleaning cycles. And we are all living happily ever after. APP made a potentially nasty repair into a fairly simple one.
