Suddenly, when brewing a cup of coffee, the water continued to run for several seconds after the cup was full. I tried all the cup sizes with the same result. I cleaned, descaled, reset the settings, and unplugged overnight. The problem continued. I unplugged the Breville and bought a replacement (Keurig). I used the Keurig for three days but, as the coffee was awful, I decided to use the Breville again until I could find an acceptable replacement. To my surprise, it's now been working perfectly for two days.
I'd like to know what caused the problem and how it righted itself, and if there is a fix if it occurs again and doesn't right itself.
Thanks, with hope!
