ELECTRIC DISHWASHERS ENERGY EFFICIENCY STANDARD

IEC 60436: Electric dishwashers for household use Methods for measuring the performance

Scope:This standard applies to electric dishwashers for household usethat are supplied with cold water.

Energy Consumption Test ProgramThe program to be tested shall be the recommended by the manufacturer for a normally soiled load.

Dishwasher Typeq Compact Dishwasher: A dishwasher with a capacity of fewer than eight

place settings and six serving pieces.

q Standard Dishwasher: A dishwasher with a capacity of at least eight place settings and six serving pieces.

Definition: Machine which cleans, rinses, and dries dishware, glassware, cutlery,and, in some case, cooking utensils by chemical, mechanical, thermal, and electricmeans.A dishwasher may/may not have a specific drying operation at the end of theprogram.

Rated Dishwasher CapacityIt is the whole number of place settings together with the serving pieces stated by the manufacturer, which can be cleaned and dried when loaded in accordance with the manufacturer’s instructions

EUROPEAN ENERGY LABELING FOR DISHWASHERS

Energy label for dishwashers

q only models belonging to energy efficiency class A andbetter can enter the market since December 2011.

q from December 2013, only dishwasher models withenergy efficiency class A+ and better will be allowed toenter the EU market.

US ENERGY STAR AND ENERGY GUIDE LABEL

The Energy Guide label estimates how muchpower is needed per year to run the applianceand to heat the water based on the yearly cost ofnatural gas and electric water heating.

TECHNOLOGY IMPROVEMENT OPTIONS FOR DISHWASHERS

Advanced Technology that reduce energy and water consumption and improve performance.

Condenser drying After all washing and rinsing cycles are complete, the dishwasher heats the dishes with hotwater from the final rinse. This water condenses on the dishwasher's cool stainless steel tuband drains away. At the same time, a built-in fan circulates air throughout the dishwasher'sinterior, speeding up the condensation process.

More efficient jetsUse less energy to spray detergent and water over the dishes when cleaning.

Improved water filtrationRemoves food soils from the wash water allowing efficient use of detergent and water throughout the cycle. The final clean-water rinse assures your dishes come out sparkling.

Innovative dish rack designsMaximize cleaning by strategically situating the dishes.

Soil sensorsTest how dirty dishes are throughout the wash and adjust the cycle to achieve optimum cleaning with minimum water and energy use.

Improved fill control

Improved motor efficiency

Increased insulation
