Moen Faucet Won’t Turn Off: Understanding the Issue

Before diving into the troubleshooting process, it’s important to understand why your Moen faucet may not be shutting off. The exact cause can vary depending on the model.

If your faucet was manufactured after 2018, the potential reasons for the issue may differ from those found in faucets produced between 2012 and 2015.

Troubleshooting for Moen Faucets Manufactured After 2018

Troubleshooting for Moen Faucets Manufactured After 2018
  1. Confirming the Lever Handle Position: Start by ensuring that the lever handle is in the correct position. If it’s improperly aligned, the faucet may not shut off completely. Adjust the handle to the “off” position and test if the issue is resolved.
  2. Performing a Faucet Handle Reset: A simple reset can often fix minor glitches. Turn off the water supply using the shut-off valves under the sink. Next, remove the handle and any decorative caps. Use the provided handle removal tool or a hex wrench to loosen the handle screw. After removing the handle, check for any debris or mineral buildup and clean it. Reassemble the handle and test the faucet.
  3. Checking the Power Source: If your Moen faucet is equipped with electronic components, ensure that it is properly connected to a power source. Check if the power cables are securely connected at both ends and confirm that any batteries are fresh and properly installed.
  4. Inspecting Water Supply Connections: A loose or damaged water supply connection could lead to a faucet that won’t turn off. Inspect the supply lines for any leaks, cracks, or loose connections. Tighten or replace as necessary.
  5. Evaluating the Cartridge or Valve Assembly: The cartridge or valve assembly plays a crucial role in the proper functioning of the faucet. Turn off the supply valves, then disassemble and inspect the cartridge or valve assembly. Look for any signs of damage or wear, such as cracks or worn-out seals. Replace the cartridge or valve assembly if necessary.
  6. Assessing for Sensor Malfunction (if applicable): For Moen motion sensor faucets, ensure that the sensors are not obstructed or dirty. Clean the sensors using a soft cloth, free from any debris or mineral buildup. If cleaning doesn’t resolve the issue, consult the manufacturer’s manual or contact Moen for further assistance.

Troubleshooting for Moen Faucets Manufactured between 2012-2015

Troubleshooting for Moen Faucets Manufactured between 2012-2015
  1. Disconnecting Power and Data Connections: For faucets manufactured between 2012 and 2015, start troubleshooting by disconnecting and reconnecting the power and data connections. This process allows the faucet to reset and recalibrate, potentially resolving the issue.
  2. Resetting the Faucet System: Resetting the faucet system can often fix programming issues. Turn off the water supply, disconnect the power cables, and wait for at least 30 seconds before reconnecting everything. This reset should help restore normal functionality to your faucet.
  3. Checking for Hard Water Buildup: Hard water can cause mineral deposits to accumulate, potentially interfering with the faucet’s operation. Inspect the aerator and spray head for any buildup. Remove the aerator and spray head, and soak them in a vinegar solution to remove the deposits. Rinse thoroughly before reattaching.
  4. Identifying Faulty Electronics: If the above steps don’t resolve the issue, faulty electronics may be to blame. Unfortunately, repairing electronic components is more complex and typically requires professional assistance. Contact Moen’s customer service or consider consulting a plumber with experience in Moen faucets.

Additional Tips and Tricks

In addition to the troubleshooting steps outlined above, there are some general maintenance practices you can follow to prevent future issues with your Moen faucet:

  1. Regular Cleaning and Lubrication: Clean the faucet regularly using a mild soap and water solution. Avoid abrasive cleaners that could damage the finish. Lubricate moving parts, such as the handle or cartridge, with silicone-based faucet lubricant to ensure smooth operation.
  2. Avoid Excessive Force: Don’t force the handle when operating the faucet. Applying excessive pressure can cause damage to the internal components, leading to issues such as a faucet that won’t turn off.
  3. Consider MotionSense Faucet Carefully (if applicable): If you have a Moen MotionSense faucet, be mindful of how you interact with the sensors. Don’t obstruct the sensors with objects or your hand for an extended period. This can lead to continuous running or difficulty turning off the faucet.
