Gary T Lee's Summit , MO January 10, 2017 Appliance: Maytag Washer MVWB300WQ1 Maytag Washer Mvwb300wq1: Lf error code. How to replace Washer Water Inlet Valve Assembly. My Maytag Bravo model MVWB300WQ1 washer had started getting error code LF (Long Fill?) part way through the wash cycle. After researching possible causes on-line, I ordered a replacement water inlet valve assembly (W10364988) from APP. The part arrived in about 5 days. I watched their installation video which walked me through every step. I was very impressed. Problem has been solved. 21 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
