Water leaks when brewing. After several cups the reservoir under the stainless plate has quarter inch of water sitting in it. There seems to be no leakage while the machine is off.

I realize you think it does not need descaling to to it 'not being used much.'
However you may have hard water and I would think descaling is definitely worth a try. There might be scale built up on the water level probes in you machine.

Descaling Details are listed below:

Brewer Model: Elite B40 ' Classic B44
Special Edition B60 ' Platinum B70

To begin, you will need the following:
• 48 ounces of undiluted white vinegar
• Large ceramic mug (do not use a paper cup)
• Access to an empty sink

PREPARE
Step 1:
Empty the water in the Water Reservoir.

Step 2:
Disable "Auto Off features."

FILL AND CLEAN
Step 1:
Pour approximately 48 ounces of the vinegar into the Water Reservoir.

Step 2:
Place a large mug on the Drip Tray Plate and run a brew cycle.

(DO NOT USE A K-CUP)

Just press the BREW Button. Pour the contents of the large mug into the sink.

Step 3:
Repeat the brew process without a K-Cup until "ADD WATER"
is indicated.

Step 4:
Now let the Brewer stand for at least 4 hours while still on.

Step 5:
Discard any residual vinegar and rinse the Water Reservoir thoroughly.

RINSE
Step 1:
Ensure the Water Reservoir is filled with fresh water.

Step 2:
Place a large mug on the Drip Tray Plate and water brew cycle. Pour the contents of the large mug into the sink.

Step 3:
Repeat brew process until "ADD WATER is indicated.

Step 4:
You may need to perform additional water brew cycles if you notice any residual taste.

Your b60 may need to be descaled. There might be scale built up on the water level probes in you machine. I have listed the directions below:

Manual version: Prepare a cup of white vinegar and 4 cups of water. Pour into reservoir and initiate "clean" cycle. Boiler was warm up, shut off and repeat over the period of about a half hour, and then finally cough up all the stuff and end the cycle. Then, fill with cold water and run a full brew cycle to rinse.

My version: Dump about a quarter cup of CLR into the reservoir, let stand for a half hour. Then, add 4 cups of water and run the "clean" cycle. After finishing, unplug and turn unit over over the sink to completely drain, use tap water to clean and flush the reservoir thoroughly, dry thoroughly and then plug in, reset the clock and brew time, and run a full load of drinking water/distilled water through to final rinse. It will last forever with my method.

there is a small rubber flap valve in the tank. if you carefully clean that on a regular basis your problem should end.

Hi, unplug the coffee machine and remove the cup.


Turn the coffee machine upside down over the sink in order to fully drain it of water. Be careful of the plug and avoid getting it wet.


Pour undiluted white vinegar into the reservoir up to the top edge of the viewing window.


Place a ceramic cup under the machine, plug it in and press "Brew" for a large cup. Pour the cups of vinegar into the sink and repeat the process until the reservoir is empty.


Remove the final cup of vinegar and empty it. Fill the coffee maker with clean water and allow it to sit for four hours, remaining on.


Unplug the machine and dump the water into the sink.


Fill up the reservoir with fresh, clean water and plug it in. Place the ceramic cup back on the drip tray and run multiple brews in order to rinse the machine of any remaining vinegar residue.

Clean it out with 1/3 caraffe distilled white vinegar and 2/3 caraffe water - you will have to dump the existing water out first. Let the vinegar/water solution sit in the water reservoir for about 20 minutes, and then press the ON button to begin brewing as if it were regular coffee. You may have to repeat the procedure up to 3 times, but it should clear out the blockage.

This morning my Keurig sounds like it begins to pull water then stops. I tried to cut it off then back on. Still didn't work.Removed water from reservoir and K-cup and added pure vinegar. Ran machine several times without filter or Kcup by pressing cup selector several times. You must open K-cup holder and close each time. I had to do this about a dozen times before the water began to draw again. Flushed system by filling water reservoir with fresh water, and brewed just plain water until vinegar was gone.Works like brand new.

Probably tye pump. If it was the hot water reservoiur it would leak without brewing.
