My Ariston AFA 250 has started causing problems. It occasionally leaks a little but it has now started to play dead. When I switch it onto a cycle it makes a single bleep as usual and then nothing. If I turn dial to reset it makes 4 bleeps. Tried unplugging for a few minutes to try and reset and that has worked a couple of times but not always. Can anyone help?
