Washing Machine

Which? surveys and other sources show that the most common faults relate to bad smells, mould, bearing failures and damaged drum paddles.

Many faults and failures can be avoided by better user instruction, simple design changes and testing to meet minimum standards.

In WRAP consumer research, consumers consider reliability, quality and expected life as the top three important product attributes; and 31% of customers surveyed said they bought products because of the brand’s association with reliability.

The cost estimates in this guide assume that cost price for the retailer is £120  per washing machine.
