I bought a new kettle two weeks ago. It has started to sometimes not switch off when boiled, just continues to boil. I took it back to the retailer who took it into the back to test it. There she found that I had not packed the base so couldn't test it. My question now is when I return tomorrow with all of it, what if it does switch off when she tests it? It seems to me that she is implying that if it switches off for her then she will not refund my money. This is an electrical item that is not working as it should, I should be able to switch on and leave the room in the knowledge that it will switch off. Any advice before I return tomorrow?
