Requirements for Dishwashers - Energy Labelling

Dishwashers are regulated for energy labelling in Australia.

Product Definition: Electric dishwashers which are intended for household or similar use.

Test Standards: Note that all energy labelling standards for dishwashers are published jointly by Standards Australia and Standards New Zealand.

AS/NZS2007: Performance of household electrical appliances- Dishwashers Part 1: Energy Consumption and Performance

AS/NZS2007: Performance of household electrical appliances- Dishwashers Part 2: Energy labelling requirements Part 1 of the standard defines the test procedures for the determination of energy consumption and performance of dishwashers in Australia.

Part 2 of the standard sets out the requirements for energy labelling of dishwashers in Australia. An approved Energy Label for dishwashers must be displayed on all products which are offered for sale in Australia.

These standards can be purchased from Standards Australia.

Overview of the Test Procedure for Dishwashers

The standard is applicable to electric dishwashers which are intended for household or similar use. A number of performance requirements must be met by dishwashers during a test for energy consumption. These include:

Washing index - the washing index of the test machine must exceed the specified value measured on the reference machine which is tested in parallel. The reference machine is a dishwasher which specially constructed and calibrated for this purpose (Miele G590).
Drying index - the drying index of the test machine must exceed 50% (this is conducted as a separate test)
Rated capacity - all specified load items shall be supported.
Water consumption - shall not exceed 110% of the value stated by the manufacturer.
Water pressure - machine shall be capable of operating at the maximum and minimum water pressure stated by the manufacturer.

Energy consumption is determined on the program recommended by the manufacturer for energy labelling that is capable of meeting the performance requirements specified above. From April 2004, all dishwashers are to be re-labelled using the "normal" program when tested to the 2003 edition of AS/NZS 2007 Part 1. The ambient air temperature is 20°C ± 2°C and the humidity is 60% ± 5%. All tests are undertaken with a power supply at 240 Volts and 50 Hz.

The Preface of AS/NZS 2007.2 describes the current requirements for energy labelling for dishwashers in Australia and New Zealand.

The Preface and Foreword of AS/NZS 2007.1 describes the recent changes in the dishwasher test procedure in Australia. It also describes the relationship between the Australian Standard and the International Electrotechnical Commission (IEC) standard for dishwashers (IEC60436-2003). It should be noted that the IEC has undertaken a major revision of the dishwasher standard over the past few years and many of the recent changes have been included in AS/NZS 2007.1-2005.
