What do I do about Valve Error?
From the Control Panel in your Flo by Moen 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 by Moen device.
When looking at the Flo by Moen device, ensure that the Manual Knob on your Flo by Moen 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 Flo by Moen device
Visually inspect the Manual Knob of the Flo by Moen device 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, especially if there is noise or damage when operating the shut off on your Flo by Moen device.
