Hi, Rusty!
Yes, you are perfectly correct in saying that most charity shops do not sell electrical goods, but you will find that the BHF definitely does ( my friend is the secretary of our local branch)
I hope you can sort something out with them.
Now, regarding Hotpoint........
Perhaps I didn't explain clearly ........the relevant tumbler dryers - Hotpoint , Indesit and Creda - were sold as new - and then found by the manufacturers themselves to have an inherent fault.
It has been all over the News - including showing burnt out machines in people's homes!
Recent buyers, such as I, were approached by the companies to check our model numbers and told that modifications would be carried out on the affected machines.
This has now been done on my machine, and hopefully it is now safe to use.
It was not the public that raised this issue, but the manufacturers of the machines, who wished to recall them.
To my mind, that invalidates the pre-existing guarantee and a new one needs to be issued in its place, dated from the modification.
All clear now?
