Question about DeLonghi DCM485 Coffee Maker

2 Answers

Won't brew Worked normally until this morning when it just stopped running the water through the system. We just realized the 4 flashing bars meant it needs to be decalcified...but we can't do it since it stopped working. We have reset the bars by pressing both clock and set. Bars left but machine still won't brew. Why does this model just stop working?Power is on normally...machine has been surface cleaned to remove clogs. What to do?

Re: Won't brew

I had the same problem, just stopped brewing. I took it apart and found a small inline fuse link that went bad. I replaced it and it brews just like new. Now it has started leaking while brewing. I am trying to find where you can purchase the rubber tubing that goes from the tank to the element. I would go to another coffee maker but my son and daughter n law gave this to my wife and I. I really hate to get rid of it.

Re: Won't brew

Bring white vinegar to a boil and pour it into the perforated top, the water reservoir and the link between the water reservoir and the brew basket. let sit a few minutes, pour it out and do it again.
put the water reservoir back in, put water and vinegar solution ( half and half) in. Try to start it again. Mine did this last year and this fixed it right away. Try to clean the coffee maker using the vinegar solution once a month to avoid this problem.

I am descaling my Keurig for the 2nd time, it fills 2 cups w/vinegar and stops and won' start again, tells me its ready, help

A. Prepare
Step 1: Make sure you have 48 ounces of white vinegar on hand. You will also need an empty sink and a ceramic mug (Do not use a paper cup.)
Step 2: Empty the water in the water reservoir
B. Fill and Clean
Step 1: Pour the vinegar into the water reservoir and fill it to the top edge of the clear viewing area.
Step 2: Place a ceramic cup in the drip tray and run a brew cycle. DO NOT USE A K-CUP...just press the large cup button. Pour the contents of the cup into the sink.
Step 3: Repeat the brew process until the water reservoir is empty, pouring the contents of the cup into the sink after each cycle. Remember to open and close the lid between each cycle.
Step 4: Now fill the reservoir with fresh water and let the brewer stand for 4-hours while it is still on.
C. Rinse
Step 1: Ensure the water reservoir is filled with fresh water.

Step 2: Place a ceramic cup on the drip tray and run a regular brew cycle. Once again, DO NOT USE A K-CUP...Pour the contents of the cup into the sink.

Step 3: Repeat the brew process until the water reservoir is empty.

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

Not brewing

it sounds like the pump inside is bad, from either a clog or fuse perhaps.the pump sends the water thru so thats the likley problem.

Doesn't always brew all the water, stops early

All coffee makers do this over time from calcium, lime, and mineral deposits building up inside the tubes and heating coil. Fill the reservoir with a 50/50 mixture of water and white vinegar and run a normal brew cycle, turning it off and on if necessary to completely empty the reservoir. Repeat this 2 or 3 times with fresh mixture of vinegar and water until it brews the reservoir empty without the need to cycle the power. Follow this procedure with plain water 2 or 3 times to clean the vinegar out. This should get it working like new again. It's best to use distilled water for brewing coffee as distilled water does not have the minerals that regular tap water has and therefore will not clog up the machine.

Water will not dispense on my Keurig Vue .Brewing process stops after a couple of seconds

It may be time to descale. Most models will give you a message when it's time to have the mineral deposits cleaned.
Empty water resevoir. Disable auto off. Pour approx 48 oz of undiluted white vinegar into resevoir. PLace large mug on drip plate, run brew cycle, dump contents of mug in sink. DO NOT USE A K-CUP.
Repeat this process until the add water light is indicated.
Let brewer stand for at least 4 hours while still on.
Discard any residual vinegar in the resevoir and rinse thorughly.
AFTER approx 4 hours...fill resevoir with water.
PLace a large mug on the drip plate and water brew cycle. Pour the contents of the mug into the sink.
REPEAT this brew process until the add water light is indicated.
YOU MAY NEED TO REPEAT THIS "RINSE" PROCESS if you notice any residual taste

Red light won't stop flashing. Parts are in place

Be sure all coffee grounds are cleaned from beneath the water tray and the grounds tray and the coffee brew group. We had the same problem but finally redid everything, including cleaning the coffee brew group under hot water, drying and replacing carefully until it clicked in place. The moving parts of brew group have to be in exactly the right place. Good luck!

I have the Keuirg mini plus and i just opened it. It flashes red like it is heating and then just turns off. No brewing.

Same here. (I have the Mini Plus B31) Called Keurig and these are the steps they walked me through. Not sure which part actually fixed the problem, but it worked.

1. Turn off machine. Using a paperclip clean out the holes in the needles (3 in the top, one in the bottom of the k-cup holder).

2. If water is inside the heating core (assuming it is as nothing happened when you tried to brew), with the machine turned off, press and hold the brew button. After 5 seconds the pump will kick on and discharge the water. Make sure you have a cup in place to catch the water.

3. Dispose of that water.

4. Unplug the machine.

5. Wait 5 seconds.

6. Plug machine back in.

7. Turn on.

8. Run empty cycle without a k-cup and only use the minimum amount of water (6 oz).

9. Dispose of that water after it brews (hopefully).
If still nothing is happening, call Keurig.

10. Brew your coffee, tea, choco, etc.

Note: was told by Keurig rep that whenever you use hot chocolate, to run an empty rinse cycle afterwards before brewing another cup. This will help prevent any choco from going up inside the machine and possibily blocking the water flow.

Hope it works! Mine did after following these instructions. The rep also wanted me to measure the amount of water that came out afterwards. Not sure what the next step would be because my call got dropped, but the machine works. Sipping on a cup now...

GE Model 169164 stops brewing

A couple of people on here mentioned he filtration system, or charcoal filter that is in the
water resovoir as being problematic. We removed it. This morning the pot brewed entirely.
Not sure how that all is inter-connected, but it worked.
