We have an Indesit which we apparently bought in 2013 so not one of the affected models. At around £500 it was not especially cheap, it seems you can now get a Miele for not much more. But even the cheapest washing machine should be safe to use.
It adds insult to injury that they now can’t even make their website useable. I don’t think that Which list is complete, it only has Hotpoint on it. The Sun had a list which included Indesit models.
If anyone needs a machine to tide them over, you might be able to get a second hand one from Gumtree or from a local auction if you have one.
