Question about Keurig Platinum B70 Coffee Maker
Posted by Anonymous on
The most common cause is that the unit has become calcified. Follow your owner manual for descale the machine, lacking that, pour a 50/50 mixture of white vinegar and water (because your machine is clogged, you could consider using 100% vinegar) into the the machine, run so that some (get as much as possible) of the weak acid mixture has been pulled into the internal water path and then shut off and leave sit. because of the large degree of scale buildup, I would leave at least overnight, if not longer. It will take a considerable amount of time for the vinegar to dissolve the hardened calcium. After allowing the vinegar to work, restart the coffee maker and allow the remainder to pass through the machine.
After cleaning, run a full pot of plain water through the machine, one full cycle, no coffee) to clean out the residue.

If the brewer heats the water but it doen not dispense this is probably because air is trapped in the tubing of the water system.
To solve, use as air compresser with minimum pressure (20-25 psi) and force air through the system using an air nozzle that is long enough to reach into the hole into the area where you fill the water. Place your hand under the dispenser and ensure you can feel the air from the compressor coming through.
Once you clean out the lines, you should be good to go.
We have had our coffee maker sitting on our shelf "broken" for months now. We tried this last ditch effort before tossing the machine in the trash and low and behold it worked! :)

I had the same problem, contacted Keurig and they suggested the descale procedure, which did not work. I was able to resolve the problem however.
First I went through a gallon of white vinegar, without results. Then I did the following:
Went to Walmart and bought "Brew Rite". Tried 8 cup mixture (8 cups of water, two tablespoons of mix), did not work. Being persistant, put in another 8 cups, let sit 2 hours and then put in clear water. By the time I got half way through with the clear water, the device started working properly, no problems since.

I called Keurig and they felt that it was likely a blockage at the needles, but despite cleaning them repeatedly, there was no improvement. They are sending me a replacement.

this is what happened to me, I didn't have the filter basket all the way down so the pot lid didn't open the valve that lets coffee flow so the coffee and grounds ran into the water resevior and plugged the filter, so I did the worst thing possible and took the filter out so the grounds got into the check valve that keeps the hot water going in the right direction. that makes it spit and sputter and brew slow.
after trying to flush it out forever I tore the metal plate on the bottom off and unhooked the rubber hoses (don't do this unless you have a needle nose pliers, you'll never get them back on) one should go to the brew head and the other is the water inlet, this has the check valve. you can tell which is which by blowing through them and seeing which one goes to the brew head. if you can blow through the other one the check valve is stuck open, I blew air into it with an air compresor and this forced the check valve shut and now it works fine. I know this is the same symptons as calcium deposits but I had cleaned it twice.
try flushing it with water first but sometimes it takes extreme measures

Cleaning & descaling your Keurig brewer is an important step to enjoying the best tasting coffee and keeping your brewer in good shape for years.

How often you need to do it depends heavily on how often you use your brewer and how "hard" your local water is ("hard" meaning how many minerals are in it). I try to do this 3-4 times a year.

Open the top of your brewer and remove the K-cup holder. CAUTION: There's are two sharp needles in there. Be careful.
The cup holder is dishwasher safe. You can toss it in the dishwasher if you want. Otherwise a good rinse under warm running water is usually good. There's a sharp needle in here, so be careful.
Turn the cup holder over and ensure these holes at the bottom are free of any obstruction.
The drip-tray is removable. Give it a good clean either by hand or in the dishwasher.
The upper portion of the K-cup holder also has a needle. This needle has three holes in it. Insert a straightened paper clip into each hole to remove any buildup or obstructions.

Here's a close up: There's nothing you can break in here, so use some force and get that paperclip a good inch in and wiggle it around vigorously. Repeat this for the two other holes in the needle.

Use a damp, soft cloth to wipe away any coffee grinds or water stains in and around the cup holder area, and down the front of the brewer.
Be careful of that needle inside when wiping it down.
Put the K-cup holder back in the chamber. Make sure it's the right way around by aligning the arrows at the top of the holder.
Empty the water in the brewer's external reservoir.

Refill the reservoir with undulated white vinegar and replace on your brewer.

Run four large cup brew cycles. DO NOT use a K-cup, just run it empty . Dispose of the hot vinegar after each. This pushes the vinegar through the inside heating tank as well as all the valves inside.

Leave your brewer to stand, powered on for four hours. This allows the vinegar time to break down any build up in the tubes and valves inside the brewer.
1 Comment 16
Discard any leftover vinegar then refill the reservoir with water only.
Run large cup cycles until "Add Water" is displayed on your brewer's screen. This washes out all traces of vinegar from the insides of the system.
If you notice a vinegar-like smell or taste to the water coming out of your brewer, refill the reservoir with water a second time and run hot water cycles until empty.

If your brewer is not brewing the full amount selected, it may be caused by the following:
?· The exit needle is clogged by coffee grounds or cocoa mix. Please refer to the K-Cup Holder cleaning instructions.
?· The brewer may need to be de-scaled. Please refer to the de-scaling instructions.
?· The removable water reservoir was removed during brewing. Place the water reservoir back onto the brewer and perform a cleansing brew without a K-Cup.
First try to make a descale maybe repeat it the next day.
