Delonghi dcm 485 power on but will not brew

I have had my Delonghi dcm485 for about 8 months and it now will not brew. In the manual it shows that when all the bars are showing it needs to be reset, thats not the problem. I've tried resetting anyway and that doesn't work.

Re: Delonghi dcm 485 power on but will not brew

THANKS "Guest" - you just saved me $100 !
I had already bought a new coffee maker (Krups) when I came across your post.  The thermal fuses (there are two of them) are indeed hidden - they are right underneath the metal braces/clamps that push them against the heating element that they are meant to monitor.  If you take off these clamps and pull back the white insulation you can easily replace the fuse(s).  What you need is:
- volt meter
- needle-nose pliers
- Radio Shack thermal fuse 228C (catalog #270-1321) - these are rated at the same temperature and look fairly identical.  They cost $1.69 at your local Radio Shack
You do NOT need a soldering iron.  So: - take off the bottom of the coffee maker - take off the clamp(s) and pull back insulation. - put your volt meter on either side of the fuse and check for continuity.  In my case, one had no resistance (good) and the other had no connection (bad). - take your needle nose and pry open the clips on the end of the wires that connect to the bad fuse ... put in the new fuse (make sure the polarity matches ... just in case) and scrunch the clips together again - replace everything
In order to make this easy to do, I disconnected the water intake/outtake and also removed the two screws holding the whole heating assembly.  Made it a lot easier

Re: Delonghi dcm 485 power on but will not brew

My dcm485 turns on but won't brew coffee and it is not that it needs cleaning. On mine, this component has failed:

Bypassing this part allows you to make coffee - but its likely that the pot will overheat, melt and catch fire without it (unless you stand there and manually turn off the pot as soon as its finished).

Also, this may have failed because another part failed.

Have you cleaned the unit?
Pour hot white vinegar into the water reservoir and lid. Rinse out and try to run again.

When i turn on my delonghi magnifica pronto on its says insert brewing unit but its already in plus it makes a really loud noise when i turn it on

Sounds like the brewing unit, or infuser, has not been properly seated into its holder. Are you sure that the two red retainer fittings are in their snapped out positions? See page 16 of your owner's manual.
If the infuser has not been properly seated it could cause a loud noise when the servo drive tries to raise the unit into its brewing position.

It will no longer brew. at all. I bought it as a Christmas gift, so we've only had it about 6-7 months! It will not brew, but the power light comes on.

The manual is available here:

You have to click on your specific model under "Combi" and then pick the "GB" attachment for the english version of the manual,

Hope this helps! Mike, The Bean Man

How do I program my DeLonghi DCM 485?

Hi and welcome to FixYa, I am Kelly

First you must set the clock. Page 6 of this pdf manual:

Then prgram per instructions at the bottom of page 6 and the top of page 7 of the same manual. I note step 2 is missing from the manual.....

3. Press the CLOCK button until the desired brewing time is displayed

(See "How to Set the Clock" section of the manual).

4. Press the ON/OFF button to confirm the automatic time selected.

NOTE: The display panel and the on/off indicator light will flash.

5. Press the PROGRAM button to return to the current time of day (the

ON/OFF button will continue to flash.) The brewing cycle will begin

once the set time is reached and the ON/OFF button stops flashing.

6. If you want to check the automatic time selected, press the

PROGRAM button.

7. To override the automatic brew function, press the ON/OFF button

and the coffee maker will start immediately. Press the ON/OFF
button again to switch the coffee maker off.

Thanks for choosing FixYa,

Have a delonghi dc78tc coffee maker and have power but it will not brew any suggestions

Try replacing the element. What is happening is is that the element is not getting hot enough to pull any water from the tank and heat it and send it up through the shower head to brew the coffee. Sometimes it can be a thermostat but more than likely it is a heating element.

I have repaired two units (DCM 485) by jumping one of the two thermofuse which failed. I assume this fuse is redundant give there is a second such fuse in-line with the heating element and a thermostatic...

You should never jumper a thermofuse no matter how convenient it can seem. All your customers have to do is forget once and you are liable. If you are a repair person then find the correct fuse or replace the unit. Safety is above all in every case.

Stopped brewing

Tim, I do not have any pics of the fuse. If you follow the 2 wires that connect to the element upwards you will find it. It is covered with a heat resistant sheath.It is right next to the heating element. The fuse is maybe a half inch long with wires on each end. I believe mine was silver. Good luck, I hope this helps you. Mark.
