Dishwasher owners should clean their appliances once a month to stop potentially harmful bacteria from growing inside.
While organising dishwasher repairs will help to keep your appliance running efficiently, according to the experts, the machine will also need to be thoroughly cleaned on a regular basis to ensure it is not harbouring any nasty surprises.
Writing in the Daily Mail, journalist Charlotte Kemp said tests on her dishwasher turned up traces of E. coli, while other forms of bacteria were discovered around her home.
Dr Anton de Paiva, bio-risk manager and deputy safety director at Imperial College London, said: "If you look behind the (dishwasher) seals, you will find mould and other nasties lurking which will be resistant to the high temperatures.
"You need to wipe round the seals once a month or so with a product like Viakal to remove mould and limescale."
