How Do I Identify My Moen Faucet?

Identify your Moen faucet by checking for your model number on the box the faucet came in if you still have it. Otherwise, Moen generally stamps the series number on the spout.

To identify your Moen faucet, check the backside of the spout, near the base where it swivels on the sink.

Moen provides this info “If you point your spout aerator (where the water comes out) so that it is facing the 3 o’clock position, the series number should be located on the opposite side at the 9 o’clock position.”

The model or series number will be a series of numbers and letters at the end. For example, the Moen Arbor MotionSense series look like this: 7594Exx.

Note, that some newer model Moen faucets may have an identifying tag that is attached to one of the supply lines.

A great resource to identify your faucet model is to use Moen’s support webpage located:

How Do You Turn Off The Sensor On A Moen Faucet?

To disable the motion sensors on a Moen faucet do the following:

To disable the ready sensor:

  1. Turn the water on using the handle

  3. The lower ready sensor will flash once, indicating it is disabled

How Do You Turn On The Sensor On A Moen Faucet?

To enable the motion sensor on a Moen faucet follow the steps below:

  1. Turn the water on using the handle
  2. Place hands over the ready sensor and wave sensor if available for 10 seconds
  3. The blue ready sensor light will blink twice, indicating both sensors are enabled
  4. Turn off the water handle

Why Is My Moen Faucet Blue Light Blinking?

The reason for the blue light to blink or flash on a Moen faucet is usually due to low batteries. The most common reasons for the Moen faucet blue light to be blinking are:

  • Moen blue light blinking slow indicated the batteries are low. Replace them with 6 new AA batteries.
  • Moen blue light blinking fast indicates the batteries are dead, replace them with 6 news AA size.

When power has been restored to the Moen MotionSense faucet, the sensors will calibrate. This means the blue light will flash, water will run for a few seconds, and then turn back off.

How To Change Batteries In Moen MotionSense Faucet

The Moen MotionSense faucets have a battery pack located under the sink. Simply locate the battery pack and remove the cover. Install 6 AA size new batteries and re-install the cover.

As seen above, when the blue light at the base of the spout starts flashing, this indicates the batteries need to be replaced.

The battery life for Moen faucets is approximately 1 year

Moen MotionSense Faucet Won’t Turn On

There are a whole host of reasons for the faucet to not turn on. First check the basics, ensure the water supply is turned on, and test the batteries. Next, follow the steps above on how to reset the sensors.

If your Moen MotionSense faucet won’t turn on, do the following:

  • Check all the wired connections. Start with the battery box wire, make sure it is not damaged and is still intact. Check how it is connected/soldered in the box itself. You just want to make sure you are getting power to the control box.
  • Check the control box. Some boxes have LED lights indicating problems. If you see a steady LED light, the control box needs to be replaced.
  • The sensors on the spout are sensitive. Any movement or possible reflections can interfere with them. Disable the lower(ready) sensor as described above so just the top(wave) sensor is active. Does this fix the issue?
  • Are the sensors obstructed? Remove the protective cover over the sensors if this is a new installation. Make sure the handle is closed fully.
  • Check the in-line filters, perhaps they are clogged. Refer to your install manual, but you simply push up on the retaining clip and pull down on the supply line.
  • Finally, if nothing above has worked, it is time to call Moen for support.

Check the handle was not left in the on position. Close the handle.

The issue may be the control box, if it has LED light indicators see if they are lit. A bad solenoid may be the culprit. Contact Moen support, they can assist in sending a new electronics box, control box, or solenoid replacement.
