My keurig B40 coffee maker just pure out water hardly any coffee. It makes it taste like a weak coffee even when it's should be strong. It was blocked and we try vinegar but that wasn't the problem. We took a needle and unblock it. Now the only thing that comes out is water and not the coffee from the k cups. Some coffee come out but it's very week. What is wrong and how do I fix it.

That whole system is run with air pressure. You need to check all the valves for deposits and proper operation.

Run the keurig with vinegar instead of water. Then run it 5 times with only water just to remove the vinegar taste. Do this once a month. Also there are pins that pokes holes on top and bottom of coffee kcups, find the pins and clean it by unclogging with paperclips or some thinner wire. Buy a K-cup holder from amazon.com. Its the black cone shaped holder.

Hi,

Sorry to read about your issue.

The brewer should be de-scaled at least every 3-6 months. Scale is harmless, but if left unattended, it can hinder optimal brewer performance. De-scaling your brewer regularly helps maintain the heating element, removable water reservoir and other parts of the brewer that come in contact with water. Better water quality and water heating means a better cup of coffee, tea, hot cocoa or iced beverage. We recommend de-scaling your brewer at least every 6 months (every 3 months if your water has a high mineral content). The de-scaling process involves using 48 ounces of undiluted white vinegar.

Take 48 oz of white vinegar. place in tank. pretend you are making coffee (Do No Use K Cup). let the water fill you mug. then empty that mug. Do it again until tank is empty. then let sit for 4 hours.
Then fill with fresh water to the top. let that tank of water run thru. towards the end taste the water.
If you taste vinegar..use more clean water, until the taste is ok.

I tried to help you. Please help me and Vote/Rate this response. Thanks and good luck

In my experience it is not possible to make good tea with a coffee maker.

Tea needs to soak. 2 minutes for weak tea or if you like it like me 5 minutes for strong tea.

Coffee makers simply run hot water over the bean powder and don't soak it long enough.

This would not hurt, but I think you just need to add a tablespoon or two more coffee grounds or until it is the strength you want.

Only the heat of the water will give you poor quality, the hotter the water
the more coffee comes out from the grounds.

If the machine is new, call keurig.. There telephone number is on the web site. They are warrented for 1 year.
