Washing machines don’t reach the correct temperature, according to Which?
An investigation by Which? has found the 60°C wash setting on some washing machines doesn't actually reach 60 degrees.
 
The product-testing charity looked at the 60°C cotton programmes of 12 washing machines, assessing the highest temperature reached and how long it was maintained. Eight of the machines did not reach 60 degrees at all, with the lowest top temperature being 43°C on the Hoover DYN8163D8P-80.
 
Most of the washing machines kept the water cooler than 50°C for the majority of the wash program.
 
Which? washing machine expert Adrian Porter said: “For years, the conventional wisdom has been to use the 60°C program to make sure your laundry comes out squeaky clean and free of bugs and bacteria.
 
“But while a 60°C wash does generally do a slightly better job of cleaning than at 40°C, the temperature of the water won't actually kill all bacteria, even if your machine is one of the models that reach 60°C.
 
“The real key to wiping out bacteria seems to be using a good laundry detergent to wash them away.”
 
Even though Which? found machines often didn’t hit 60°C, manufacturers are not actually cheating the EU energy labels because there’s no requirement for the washing machine to reach the temperature stated on the control panel.
