Spinning back for its third wash cycle, the State Government's Washing Machine Exchange Program is offering discounted units for those battling to keep their sheets clean in these tough economic times.

The initiative allows eligible pensioners, veterans, social housing tenants, and low-income households to trade their top-loader for a brand new 8kg water- and energy-efficient front-loader for just $250. The exchange will allow up to 6000 households to also enjoy an average of $300 a year in reduced water, electricity, and detergent usage.

It's expected each participating household will save around 20,000 litres of water annually, enough to fill a typical backyard swimming pool, according to Ashraf El-Sherbini from the NSW Department of Climate Change, Energy, the Environment and Water.

"Modern front-loading washing machines use significantly less water than older top-loaders, so this program is one of the most effective ways households can cut their water use," Mr El-Sherbini explained.

"When thousands of homes make this small switch, it amounts to millions of litres of water saved across the state, contributing to longer-term water security for NSW," he added.

The subsidised package for eligible concession cardholders includes delivery anywhere in NSW, installation, a two-year warranty and removal of the old machine for recycling, all facilitated by The Good Guys Commercial. Its managing director, Biag Capasso, said:

"We're proud to partner with the NSW Government on a program that delivers real savings to customers through more efficient appliances," Mr Capasso enthused.

"Our team handles everything from delivery to installation and recycling the old machine, making it a smooth experience for households in need," he added.

Since launching, the $11 million Washing Machine Exchange Program has helped nearly 12,000 households upgrade their washing machines and save an estimated 233 million litres of water, enough to fill 93 Olympic-sized swimming pools, Minister for Seniors Jodie Harrison said.

"This has been a very popular program, so eligible seniors should get in quick if they have an old top-loader they would like to replace," Ms Harrison urged.

"The energy savings from the new machine also add up over the long term, helping older people lower their household bills over time," she concluded.

The Washing Machine Exchange is part of the NSW Water Efficiency Program, which is leading the NSW Government's efforts to reduce water waste, strengthen water security and help households keep more money in their pockets.

The past two rounds saw all available washing machines snapped up within a week, which is why the program has been brought back for a third spin.
