Muqeem M South Grafton , MA April 24, 2023 Appliance: LG Dishwasher LDF6920WW Lg Dishwasher Ldf6920ww: Dirty water was flowing back into the tub. Found check valve damaged. How to replace Inner Pump Housing. My drain hose ruptured and when I went in to replace the hose, I found a piece of the check valve stuck in it. When I went in to confirm if that was indeed the check valve, the inner pump housing tabs broke as the plastic had become brittle over the years. So what started as a simple repair turned into a project. Fortunately, AppliancePartsPros.com had all the parts I needed, and that too at very reasonable prices - OEM parts at non-OEM prices, what a relief! Items were shipped really fast and I got them within a day or two. The replacement was very easy as AppliancePartsPros.com had video tutorials that showed step-by-step how to replace the housing and the check valve. I think the whole process took me maybe 15-20 minutes. Quite honestly, I am extremely pleased with the service from AppliancePartsPros.com - from the video tutorials to getting OEM parts within a couple of days. I could not ask for anything more. Thank you Appliance Parts Pros! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
