The Government is due to issue a recall notice for up to 500,000 Whirlpool tumble dryers.
The dryers pose a fire safety risk.
It is four years since Whirlpool issued a warning after it found its Hotpoint, Creda and Indesit dryers had a fault which needed fixing.
According to the Government, the fault could be the cause of at least 750 fires over 11 years.
Anyone still owning any of the affected models is asked to contact the company immediately on 0800 151 0905.
A spokeswoman added: "In the meantime, anyone with an affected dryer that has not been modified should unplug it and not use it until the modification has been completed."
It is thought up to 500,000 of the driers could still be in use.
If you have one of these models, or you are not sure what your model is and you are worried it might be dangerous, contact 0800 151 0905 now.
