This is a very common problem in areas that have hard water. With any type of check valve buildup inside the piece will cause it to Fowell up.
Part# 30024442A
Cost $6.95
You can get this piece in the NPE parts service kit.
It's very important to check this valve when you do your yearly or Quartey service on your customers unites.
It's also important to work the interior/exterior valve.

Great video. I have replaced multiple parts on my NPE 240A...Flow sensor and PCB. After I changed those parts , we started getting cold water on the hot. So I think it is the check valve The unit is about 2 years old.

Be careful with that “push-turn-wiggle”, more often than not, you’ll be buying baby formula in about 9 months.

That notch is at 11. I know, I know. Not important. Great video.

Just so I understand fully, you install a valve on the return line and hook up a hose to that and the cold water side to clean it out? You don’t have to hook a hose up to the hot? I have the A series with an internal pump too.

What is the purpose of applying heat proof grease on the O ring and can you provide the brand of the grease? Thank you for the informative video.
