Hotpoint tumble dryers recalled for fire risk from fluff contacting heating element (models April 2004–September 2015)
Safety risk
The documented fire risk is fluff contacting the heating element. The recall window ends 30 September 2015, so post-2015 Hotpoint dryers fall outside this recall; the risk applies to 2015 and earlier production.
What to check. If the dryer was made in 2015 or earlier, check the model/serial against the affected list and unplug if unmodified. Post-2015 units are outside this recall window.
UK government ordered recall of up to 500,000 unmodified Hotpoint/Indesit/Creda tumble dryers (June 2019)
The Government instructed Whirlpool to recall 500,000 tumble dryers in June 2019, four years after the fault was first flagged. This is the scale of the documented fire risk for Hotpoint-branded dryers.
What to check. Confirms the fire risk is real and regulator-recognised, with hundreds of fires linked to these machines. Check any Hotpoint dryer made up to 2015.
