How to Troubleshoot & Replace Whirlpool AP2910020 / 675238 Check Valve Assembly

Replaced the impellers using a repair kit. Repairs were easy me went according to the video. Unfortunately, the dishwasher still does not drain on all washing models - which leads me to believe that it was not the impellers, but probably the control panel. I will drain on a quick wash and all other cycles except normal wash. 

I purchased both the check valve and impeller kit. I watched the videos as I worked. This was great!! I have never worked on a dishwasher and both of these videos were exactly right. Dishwasher is back in good working order. I am very, very happy! 

Smooth and no trouble. 

Would not drain. I ordered the drain and wash impeller kit. Watched the install video that was provided by them. It was easy and informative but would recommend for you to purchase the seal that he says does not come with the kit. Mine was worn out. Delivery was quick and easy and got everything provided. appliance parts pros is a good site. thank you appliance parts pros

I ordered a new check valve from Appliance parts received it in two days and took 15 minutes to install.it. We are back in operation - Thank you for your fast response. 

Replaced the check valve. Works fine now.
