Whirlpool washer - what is this error code?

My washer just quit working. It runs but then at some point during the wash cycle it stops and just beeps. I researched it and it looks to me like it’s an F1E8 error. But there’s no reference to that in the manual. The LED flashes once, then pauses, then 8 times, then loooong pause. And repeats.

There is a reference to the reverse error (F8E1) but I don’t THINK it’s the same thing. I’m stumped as where to look to fix this thing. Can anyone give me tips?

I’ve already reset it by unplugging it for a while and I’ve cleared the large item trap thing. Anything else?

Thanks!

No tips at all? I’m completely stumped. Do I just randomly start replacing things? It gives me no clue at all what isn’t working.
