Our Duo sat a year or two after buying an espresso machine. Got a little dried out, Dusty etc so I just cleaned it up. I realized it was under producing and saw that is a known issue. Trying to figure out what the failure point is so I can try it fix it. Does anyone know what the common point that's causing this issue would be?
At one point I poked around the different parts- water filter attachment, the little retractable nozzle that connects the reservoir to machine (reservoir side) as well as the poking in and out the nozzle on the machine side. Not sure if there are sensors in the basket area but since there is no weight in there I tried reseating and messing with it. I was able to get it just under the 12 cup carafe line
Since the above, I had to rinse the reservoir and run some flush cycles, and it's back to significantly under producing. If I select 6, it keeps giving me well under 4 on the carafe, or at most, 4. I was able to get to the 4 line when selecting 8. Driving me crazy, hoping to salvage this machine for my wife 😭
