Why is my Dimplex 6909660400 underfilling when plumbed to a water source?
- JJerry RussellSep 1, 2025
If your Dimplex Indoor Fireplace unit is underfilling or not filling, and it's hard plumbed to a water source, first ensure that the unit is level to allow an accurate reading of the water level. Check that the ball valve of the unit is open and water is getting to the unit. Inspect the sump to ensure floats are installed. If these steps don't resolve the issue, the level sensor assembly may be defective and require replacement. Also, put the unit in test mode to test the operation of the solenoids; if they are not working, replace the solenoid.
