I just bought a 2nd hand toaster, it toasts fine, but there is often a little blue flash as it finishes, or if I press the cancel button. I’m not sure if this is a problem or not, I have had a couple of other devices ( a heater and a kettle) that did the same thing, so is it a problem?
Also, I’ve bought 2nd hand electrical stuff before from this shop, and they usually have a “passed safety testing” sticker, but this item doesn’t, is that a worry?

The blue flash is coming from inside the toaster, and no I don’t have DMM.
