Our Asko Model D3122 will not shut off. It keeps making a noise as if it is trying to drain, but the cycle is completed. It does not respond to pushing the start/stop button. The only way to get it to stop making the noise is to unplug it. Please help. We have had it for about 7 years and have been very happy with its performance until now.
