When empty flush with a tank of water.

Tanks - Water/Steam

Check that water/steam distribution holes in the water & steam tanks are clean and clear.

If holes are blocked or dirty steam will not distribute evenly.

Regularly inspect the power cord for blisters, kinks and exposed wires.

These may occur by running machine over cord or tightening cord to hard on the handle.
