If you have a Bosch dishwasher I urge you click on this link and check to see if your dishwasher could be affected.
My friend only found out in the middle of the night when her smoke alarm went off – she then found flames pouring out of her dishwasher. As you can see from the above picture, they are very lucky they had a smoke alarm.
This is a known fault which means that any of the dishwashers listed here could potentially be a fire risk. Please check.
Also – please make sure that you have a smoke alarm and that it has a working battery.
