Question about Keurig B70 Coffee Maker

1 Answer

I'm having issues with my B70 after 1 1/2 years of usage. It seems to not be able to brew on 8 and 10 ounces. It starts to get water, then makes the water push sound, and doesn't brew. Only method I've been able to discover on fixing it is by turning off the K machine and turning it back on, then brewing 4 ounces and it pumps out 12/14 ounces. Does anyone have any suggestions on fixing it other than calling Keurig like an option to purge the tank I can't find?

    The Keurig never produces anything over 8 ounces even though you should be able to get as many as 16.

What do I do when my keurig is set on 8 ounce and it keeps brewing


This is going to sound a little funny. Try descaling it. Mine runs excessive water when it needs to be descaled and we live in an area with rather mineral heavy water

What isthe proper coffee to water ratio


Most coffee brewing sites say to use 2 tablespoons of ground coffee for 6 ounces of water. Since the grind can vary, they also say to use 10 grams of coffee per 6 ounces of water. Going by weight ensures the proper ratio.

If you're making coffee for yourself, of course, the proper ratio is whatever gives you the taste you most enjoy. Start with the 10g-to-6 ounces ratio and adjust as desired. Not all roasts and beans brew exactly alike.

Don't forget to keep your coffee maker clean, and use filtered water. This can have a great effect on the coffee's taste.

Did not make the large cup of coffee. Then we de-scaled the machine with vinegar. The computer seems off. The hot water is coming back into the water reservoir.


1. Power off machine.

2. Using a metal paperclip, insert it into left side of top needle. It must insert at least 1" deep. Insert it into slot on right side and again from back of needle.

3. Remove KCup cradle. Separate bottom from top. In the top section, insert the paperclip up into bottom needle from the bottom upwards. It will not go all the way thru and this is normal.

4. Reassemble KCup cradle and reinsert it back into coffee maker.

5. Power on machine.

6. Brew a cup of water only. There may be coffee grounds in the water and these should eventually clear during the remaining steps. NOTE: A large cup brew cycle should output a full 8 ounces (235cc). Less means there is still a blockage

7. Empty reservoir and fill with undiluted distilled white vinegar. Repeatedly run brewing cycle until Add Water light comes on.

8. Make sure Auto-OFF is NOT set and let last cycle of vinegar remain inside machine for 4 hours.

9. Refill reservoir with fresh water and repeatedly run brewing cycle until the water is clear and odorless.

10. Set Auto-OFF, if preferred.

How many tablespoons of ground coffee are needed per cup of water in the Smart Brew coffee maker?


For ground coffee, use 1-1/2 (one and one-half) tablespoons of beans per 6 ounces of water.

For whole bean coffee, use two tablespoons of beans per 6 ounces of water.

Coffee strength is a very personal preference, so use these numbers as a guideline for middle-of-the-road coffee, and adjust to make the coffee that you like to drink.

I put in 6 cups of water and only 5 cups brew. It


The amount of water you put in the carafe isn't the same amount you'll get out of the coffee maker, as some of the water is normally lost as steam vapor during the brewing process.

I would also look at the water level gauge inside the reservoir or on the sight gauge to make sure I have added the right amount to make the amount of brewed coffee I want.

As to the filter pre-soaking issue, it shouldn't matter since you likely made several pots since then and the filter has likely expelled any residue already. I would run a full pot of just water with a filter in the basket, just to see if you're getting a full carafe after brewing, making sure you have a full reservour to begin with.

As to the grind of the coffee, I find that a medium coarse is best for all but expresso coffee. However, you might want to experiment with your grind settings until you find the setting that makes the coffee to your likeing and taste. Coffee is all about what you like to drink, so take some time to find what you enjoy.

I use a high-end filter for all my drinking and coffee brewing water to get the best possible taste as it does make a difference.

My nieighbors have the same coffee machine and use the same coffee brand, etc., but don't filter their water. They've noticed the difference and always comment that they need to get a filter for their water.

When I run white vinegar thru my machine, I always run at least two (2) full pots of plain water thru the unit before I start making coffee again, to rid the reservoir of any vinegar residue.

Hope you find this helpful and best regards!

Keurig maker dispenses too little water when brewing


I found this solution on another post. Unfold a small metal paper clip and insert through the lower piercing needle of the cup holder to **** out any debris in the needle.Even a small piece of coffee or debris can slow the water flow through the cup.

Saeco Vienna No creme' and can't lessen amt. of water in shot


Hi
Have you taken apart the brew unit lately? If so you did not put it back together correctly. Sounds like you have lost the crystal ball or you installed the spring upside down, in the brew head.

Incomplete brew


Sometimes you have to do the decalcification two or three times. Then, monthly after that.

Cuisinart Coffeemaker Decalcification Process

Run 2 cups distilled white vinegar and 2 cups water through the system - brew it like it was regular coffee. Then run plain water through the coffemaker to rinse the vinegar out and make sure the decalcification was successful. Repeat as needed. Don't forget to remove the charcoal water filters first.

Water in dump box


You have more than one problem.
You need to order a new filter since, if it is stripped, you cannot use it. The water in the dump box is caused either by that filter not being clean and not allowing the water to pass, thus dumping it into your dump box(the usual case), or a worn or failed O ring.
The other problem, the brew group not working, could be caused by any number of issues and would need more information. You may simply have not put it back on properly or got the timing sequence off.
