Why is my Keurig still producing weak coffee?

Background: I was gifted a brand new Keurig 475 Series Plus 6 months ago. In the past month, it went from brewing good coffee to brewing what you can basically call weak coffee water. (Note: I use a refillable Keurig pod that I wash after every use so as not to produce too much waste with the K-cups.)

Steps to Remedy the Problem:
  • Descaled the machine with cleaning solution - as outlined in the manual and on their website.
  • Clean the entrance needle once a week as directed.
  • Removed the area where the pod sits, cleaned it as well as the exit needle.

Still getting weak coffee water - barely even tastes like coffee.

Looking for further tips or insight on what might be wrong with my machine.

When I set up the machine, it said if you use filtered water (which I do) you didn't need a filter.

Did that make it better?

Wish I could, Justin, but I love coffee too much to give it up entirely. :)

If the filter is nasty looking or smells gross, I'd be inclined to replace it, which is what I did with mine.  But if you don't even have one then disregard.  I read on my manual that it needs to be replaced every so often like a Brita water filter.

Ah, that's good to know. I will check it when I get home this evening. Thank you!

I use a refillable Keurig pod

If the coffee ends up being watered down with your current pod, it sounds like the water is filtering through the medium too fast. To get a strong brew, the water needs to slowly make it through the medium.

Any chance the bottom of the pod or the screen is worn out? Any chance there is a hole punched in the bottom of the pod?

Have you tried a different pod, or one of the standard non-reusable pods to see if it occurs with all of them? Have you tried packing the coffee down tighter in the pod?

This doesn't help answer the question, but in case you don't find a solution for this, cold brew is almost as easy as a Keurig. Scoop some coffee grounds into a pitcher, add water, and you're done. I love cold brew. As a bonus the coffee loses some acidity and bitterness.

Thanks Lucas, the refillable pod is intact as far as I can tell. We pack it pretty tightly when we use it.

I do not have any standard, non-reusable pods on hand but will get some at the store this week to try it out and see if that's the problem.

Thanks for the suggestion, Brandon! I know, I'm contemplating getting a regular coffee pot. Shouldn't be this tough to maintain a coffee maker.

And Kyle, I do not have a water filter. Checked last night. Since I use filtered water in the reservoir, I never installed one.

Do you grind your coffee right when you make it or does it come from a pre-grinded bag of coffee?  
Do other coffee grinds produce this same watered down coffee?
Brandon LyonSenior Frontend DeveloperCommented:
^ That's a good point Kyle. A grind size that's too small might be slipping through the mesh and changing the coffee strength.

I use pre-ground coffee. I've tried Starbucks, Dunkin Donuts, World Market, and a Target store brand and it's all the same. (Note: They all tasted fine until about a month ago. Since this issue, they all taste poorly.) Thanks for the suggestion!
Picking up a k-cup pod on my way home to see if it brews differently with that versus the reusable pod. I'll let you know what I find out!

Process of elimination is just about all you have left to do! =)

OK, update:

Tried a k-cup pod - same issue. Tried a different reusable pod - same issue. So I'm guessing it must be the machine. I'll get in touch with the manufacturer. Thank you, everyone, for your tips!
