I put this dishwasher on, forgetting that I’d closed the stop valve under the sink closed before I went on holiday. I think the machine was struggling to fill up all night and had stopped working by the next morning. I did this before a couple of years ago and it started working again after a day or so – but now nothing is happening. The light still flashes to say wash is in progress, but there is no noise to indicate machine is trying to fill up. Is there anything I can do? Thanks
