Shoutout to the LG control board that ate 11 hours of my week

Heads up for anyone running into the same thing: I had a front load washer throwing an OE error and I swore it was the drain pump, so I swapped it, checked the hose, and still got the code. Turned out the pressure sensor hose had a tiny crack near the clamp that I could not see without a flashlight and a mirror, and the water level reading was lying to the board. What should have been a 45 minute call turned into 3 trips to the customer's house in Mesa and 11 total hours by the time I chased the wiring harness too. Has anyone else gotten burned by a hairline crack in the pressure hose? Did you find it on the first visit or the third like me?
