Front Load Efficiency Study

City of Portland Washer Efficiency Study
A recent study conducted by the City of Portland's Office of Sustainable Development, in collaboration with the Portland Water Bureau, Northwest Energy Efficiency Alliance, Oregon Department of Energy, and Coin Meter Co.

The study result at a glance: Average WATER Savings from Front-Load Washers:8 gallons/load $0.01/load (includes sewer)

FRONT LOADING MACHINE DISADVANTAGES"Front loading machines often require more maintenance. One of the advantages of front loading units is that they need less detergent. However, communicating this fact to users can be difficult and detergent overloading is common which leads to oversudsing. Too much detergent will clog fill lines and render the washer inoperable leading to user complaints. This in turn leads to additional service calls to repair the unit."

"Another challenge with front-loading machines is that, by the nature of their design, the loading door must lock after the machine has filled with water. Opening the door after it has filled will result in water spilling out of the unit (Top loaders can be opened at any time during the washing cycle). Sometimes the door will be forced open so that a missed item can be included in the wash. This action allows water to discharge to the floor creating a hazard and requires the door to be repaired.""The front-loading door swings open out over the floor area. In doing so, any residual water left on the door can potentially drip off onto the floor creating a hazard."
