If you are using the cup where you can add you own coffee, you must SCRUB the little screen inside periodically. I soaked mine in vinegar for several hours without success. But I used clorox scrub stuff and a wire brush....magically...a full cup of coffee. I have no solution if you are using the boxed K-cups and have this problem.

Why does my Keurig only fill partial cup when it is on large cup and only seems to happen with a bold coffee

According to my Platinum manual your exit needle may be partially plugged clean carefully with a straightened paperclip. Run a couple cycles without a K-Cup inserted. This should fix your problem.

Not enough water making it from holding tank to dispensing cup

your machine is "Short Cupping"

It needs to be descaled. Even though the descale light might not be on yet, the descale light only comes on when it is in SERIOUS need of a descaling. You should descale once every 3 months.

Fill reservoir with distilled white vinegar and leave the machine on for 4 hours (make sure to turn off the auto off option).

after 4 hours, run the vinegar through the machine until the reservoir is empty. Refill with water and repeat twice. you will notice a difference right when you start running vinegar through.

Descaling light on

Per Pages 9 and 10 of Keurig Model B40 Use and Care Guide,
1) turn off the "Auto Off "feature
2) fill empty water reservoir with 48 ozs of undiluted white vinegar.
3. Place ceramic cup on the drip tray and run a brew cycle. Do not use a K-cup!
4. Press the large mug Button
- let Keurig coffee maker fill mug with vinegar & empty in sink.
5. Repeat brew process until water reservoir of vinegar is empty. (remember to open and close lid between each cycle so large mug Button will flash.
6. Rinse the water reservoir thoroughly and fill with fresh water.
a) place a ceramic cup on the drip tray
b) run regular brew cycles WITHOUT using a K-cup.
c) pour rinse water into sink each time.
d) repeat brew process until water reservoir is empty.
d) perform additional rinse cycles if you notice any residual vinegar taste.
e) if the red "De-scale" light remains illuminated after completing descale and rinse cycles, repeat the descaling procedure above.
Otherwise - you're good to go!
