Tight Mixer Cartridge

My family has had a Dishmaster faucet for as long as I can remember, around 75 years! We love them. My M70CPHA developed such a hard and tight water controller/mixer cartridge that wouldn't go away, even after removing it, cleaning it and lubricating it. OK, no problem, so I order a new one. The new P4020 Mixer Cartridge has the same problem, too tight and difficult to turn water on/off or to regulate water temperature!! I am open for suggestions?

Our records indicate we have spoken with you in the past regarding this same issue. Your water sourse is a well. You have a softener that addresses hard water but not other minerals or debris that may be in your in your water. We will email instructions to you for cleaning the cartridges. By the way, we believe you have an M65SHA rather than an M70CPHA.

Mixer Cartridge

After many years of operating properly the mixer cartridge started to leak and was replaced with a new cartridge that for the last two weeks is working as designed.

Thanks for sending this part. It was easy to install and it works like a charm!
I always get great help when I call with an issue. We have had Dishmaster in our house 45 years and our parents had one before that!
