We have a Moen Motionsense single handle kitchen faucet that we had installed 2 years ago. The other day the water stop shutting off. I unplugged the motion sensor under the sink but the water continued flowing out of the faucet. We turned off the water supply and decided to try replacing the Moen cartridge. After we installed the new cartridge and turned back on the water, the faucet continued to flow. The handle does not control turning off the water. We aren't sure what we should try next. Any help would be appreciated.

It’s the solenoid in the control box. I have the gray 7 hose control and have
Replaced the control 4 or more times now in the 5 yr warranty period. They say that I’m the only one
That had issues with this but I’d say that this is proof that I’m not by myself. If you turn it on with touch free and it doesn’t shut off,operate the spray trigger on the head and it will usually shut it off. Mine aways starts by being sluggish shutting off and within a couple weeks it gets to the point it wound at all.
I have checked and cleaned all the filters as instructed. Changed the batteries as instructed making no difference. I have talked the controller apart to inspect for calcium build and any other reason for failure and found it to be in the pilot style solenoid on the manifold. I am in the refrigeration business and deal with water valves that operate in the same manor but designed slightly different. So I am well aware of how their suppose to operate. Bottom line is a poorly designed valve. They have admitted to me already after the 2nd control that they had a design change in th valve to help this.
But 2 more controls later it seems as it hasn’t solved the issue.
They now have a 3 hose black control. Not sure if this was to address this issue or not. Not sure where I’ll go next round. My 5 yr warranty is up in December 2018. Anybody else having issues as this with a better remedy, other that the trash, let me know.

Cbc,
I too am on my second replacement control box. Went through exactly the same trouble shooting. They even sent me a replacement 'electronics' box previously to see if that was the problem. No dice, called back and they sent me the new control box. I sooo wasn't looking forward to it, as pulling the hoses out of the control box is a complete pain in the @ss. I disassembled the old unit as well, looking for calcium build up - here in Sugar Land, TX we've got very hard water. I didn't see anything entirely unusual. I figure like you did that it's the solenoid sticking just a bit. It doesn't appear to move that much, since now I've got an old control box and electronics box to test. I'll wait till this new one fails, I'm guessing in about 1 1/2 years. Then replace the solenoid. My 5 year warranty will expire soon as well...

In this situation, normally it is caused by the poor solenoid valve, not working or keep opening.Try to replace it with a good quality solenoid valve or bi-stable valve. You can visit [www.tap-sensor.com] to follow the instruction and contact us.
Thanks.

Mine has worked flawlessly for seven years and now dribbles rather than fully turning off.

I am pretty sure my grey box with seven hoses is obsolete. I can't seem to find it online to buy.
I took apart the entire box and the solenoid. I put it back together and it failed to shut off--I had gone fully backwards.
I took it apart again and found that there are two tiny holes on either side of the rubber disk that the magnetic coil and rod act upon. I cleaned the two holes with dental picks and made sure they were aligned with the matching holes in the rubber.
I assembled and have solved the problem completely.

I too experienced the slow turn off symptoms. Removed the control box, inspected for deposits, found none. Cleaned the filters and re-installed but problem persisted. But I lucked out and was able to find a brand new gray 6-hose control box on EBay. Replaced the old control box and was back in business. But then I stumbled across this thread and was intrigued by the previous poster who said he solved the problem by cleaning a couple small holes. I didn't recall seeing any holes, so I took apart the old unit to further investigate. Sure enough, there are three tiny holes on the rubber valve seal assembly. I looked through the holes in the plastic insert and none of them were clogged. I decided to remove the pin from the solenoid assembly and stretched out the spring so that it has more force to push the pin outward It's easy to test the solenoid, since the polarity across the red and black wires determines whether the pin retracts (flow on) or extends (flow off). Stretching the spring makes it easier for the solenoid to extend the pin. The water flow now stops immediately. Problem solved, and now I have a brand new spare control box for future needs.
By the way, this is my second control unit. The original caused a drippy faucet because the rubber valve seal assembly inside the control box split. They don't sell just the valve seal, so Moen sent me a whole new control box for free, which is the one I just repaired.
I'd also recommend that you purchase a new replacement hose that runs up to the faucet nozzle. Although it appears to be a high-quality hose with stainless steel braiding, it's only a flexible plastic hose that can get brittle and split. The braiding isn't stainless steel either. Mine leaked water all over the cabinet under the sink before I knew there was a problem. I was able to jury-rig a splice while waiting for the replacement hose to arrive. I might order another one, now that I have a spare control box.
To make a long story even longer... the new 3-hose black control box is for MotionSense faucets sold in 2015 and later. Their marketing research claims that people prefer adjusting the water temperature with the handle. That new design also simplifies the control box. The downside is that there's no battery backup. If you lose power, the kitchen faucet doesn't work. I prefer the old control box, especially now that I have a new spare one.
