Valve Error

This article includes detailed information on the Flo Smart Water Monitor and Shutoff, also known as the Flo by Moen Water Shutoff. It also refers to the Moen Smart Water app, also known as the Flo by Moen app.

 What does Valve Error mean?

Valve Error is a system warning that the Manual Knob on your Flo Smart Water Monitor and Shutoff may not properly be in the Open or Close position, or may not be properly synced with the Smart Water Network . While there is a Valve Error, your home may not be properly protected from water damage because the Flo Smart Water Monitor and Shutoff may not properly be working. It is therefore important to troubleshoot this issue as soon as possible.

What do I do about Valve Error?

From the Control Panel in your Moen Smart Water app, try to Open and Close the valve.  If the On/Off toggle on the Control Panel is dimmed, or if you cannot Open or Close the water, it’s time to inspect your Flo Smart Water Monitor and Shutoff.

When looking at the Flo Smart Water Monitor and Shutoff, ensure that the Manual Knob on your device is free from any debris (leaves, twigs, pebbles etc.) that may be restricting the ability of the valve to be fully Open or Close. If you notice any debris, carefully remove them from the device  

Visually inspect the Manual Knob of the Flo Smart Water Monitor and Shutoff to see if it’s in the Open or Close position.  If it appears to be somewhere between Open or Close, try manually Opening or Closing the Manual Knob.  

For additional troubleshooting tips, contact Flo Support or call 844-Meet-Flo, especially if there is noise or damage when operating the shut off on your Flo Smart Water Monitor and Shutoff.
