This cartridge is auto-off except under conditions of low or unreliable water pressure, sediment and particles in water, buildup of lime, salt, iron or other mineral deposits, etc., in which case it must be disengaged manually by the user.
Before You Replace It - Be Certain You Are Operating It Correctly
Make certain it hasn't accumulated buildup, sediment or particles
Make certain there is a clearance gap between the diverter knob and the faucet body.
We are third generation Dishmaster customers with various model faucets in main and vacation homes across five families. Due to the nature of the sink unit we installed we needed the M70 High Arc model. We have had this faucet 4 years and are on our 3rd replacement diverted cartridge. Because times are tight we will replace one more time. After this one we will be leaving the Dishmaster family and buying something cheaper and more reliable. Very sad, because these faucets remind us of grandparents and great grandparents.
We're sorry to hear that you're having problems with your nearly 6-year old M65 Sapphire. Unlike previous Dishmaster models you might have owned, the diverter on this model is much more sensitive to varying water pressure & conditions. One of the replacement diverters you received was sent under warranty after you contacted us. The others were ordered online with no input from our customer service. We're always happy to speak with customers to help diagnose any issue and see if we can correct a problem. Please call us at 800-521-9234. We're available from 8am-4pm EST, Mon-Fri. We'd like to discuss the issue you're having before we ship your current order so that we can try to make sure you get what you need.
