The insides of a K-Cup brewer
Back in March of 2011 did a blog post with my comparison between the Breville and Cuisinart K-Cup brewers. You can read that post here
I then made an update at the bottom of that post indicating that the Cuisinart had died after only 7 months. On Dec 14 a user by the name of sezron commented that the reason these machines keep failing is because they use a car part designed for turning on and off the flow of air. Well that sounded pretty interesting and it just so happens that I still have my first dead Breville sitting in the basement; don’t even ask why. I finally got around to taking it apart to see if this was true. So here we go.
Here is a picture of the Breville upside down with the bottom plate removed. At this point I can’t see much of anything.
Next I remove the bottom plastic plate which opens up quite a bit more of the machine. Still not nearly enough to trace the water flow and see what devices are on the inside.
Finally, after much cursing I have the entire back off the unit. It is still upside down. You’ll notice two cylindrical devices with hoses going into them near the bottom of the picture.
And here is a close up of those devices.
After getting the rest of the plastic removed I was able to get a much better look. This is a close up of one of those devices.
Sure enough, it is a pneumatic solenoid valve with water tubing connected. This one was on the right hand side of the machine and it appears to have failed. Here is a picture of the one on the other side of the machine.
Well, at this point I don’t know what to say. Is it a bad design? I’m not sure but I’m leaning that way. These valves are not designed for turning on and off the flow of water. I’ll let you all make your own decisions.
