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.

Works like new

Changed both the diverter and mixing cartridges. We live in Mexico and our cistern water pump got dirt in it so it contaminated the Dishmaster. Easy change out procedure and now it’s perfect.

fix faucet leak

Faucet was leaking from the mixer cartridge side of my M70 Sapphire. Tried new o-ring and grease, but didn't work, so ordered a new mixer cartridge. Worked perfectly and only took a few minutes to install.
