Chosen Solution
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!
I hope this explains a what/why on what may have occurred. My recommendation is, if it’s no longer playing up, leave it. A rare occurrence with breville coffee machines is having the water pump flow when it shouldn’t. The worst scenario I have heard about (from a tech, but not me) was one that would turn itself on, run the pump until all the water was gone. It’s very uncommon, I only know about it affecting Breville. Breville is also marketed as Kambrook, Ronson, and in the UK ‘SAGE’. What you’re describing sounds like this, but impossible to say for sure. For the record, I love breville coffee machines, i’ve owned 4. The issue is with a leaky electrolytic capacitor in the power supply board, combined with the soft-start standby mode. Replacing that caps corrects the issue. That was 11 years ago for me, wow. Here is a post I added to about it. https://siber-sonic.com/appliance/800Ele…
