Question about DeLonghi DCM485 Coffee Maker
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.
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

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.

In order to keep your Tassimo machine
operational at full order, it is important to descale it every three
months. Descaling products are widely available from stores that sell
coffeemakers and espresso machines. Be sure that the product you buy to
descale your Tassimo machine is intended for this specific use only. Mix
the descaling product directly in the water container, following the
instructions provided on the descaling packaging. Then replace the water
container on the machine. Place a large cup or mug on the cup stand,
insert the cleaning disc, bar code down and close the brew mechanism. As
soon as the AUTO light illuminates, press and release the start/stop
button. This will fill the brew cycle with descaling solution. Empty the
cup and let the machine stand for 15 minutes. Then open the brew
mechanism and close it again, leaving the cleaning disc in place. Repeat
this step two more times for maximum descaling effectiveness.
Discard the remaining descaling agent from the water
container, rinse it well and refill with fresh, cold water. Clean the
machine by flushing water through it in the same manner and emptying the
cup as it fills. Make sure that all the descaling solution has been
completely rinsed away, and then flush two full water containers through
the machine before using it again. Remove the cleaning disc, rinse and
refill the water container and your Tassimo machine is ready to use.
Also, before you descale your Tassimo machine, always unplug it. Also,
never immerse the appliance in water and nor should you use abrasive
cleaning products or scouring materials on any part of your Tassimo
machine. This method works for most espresso machines,
including some of these popular models: the DeLonghi Magnifica
EAM3200S, DeLonghi Magnifica ESAM4200S, DeLonghi Perfecta ESAM5400,
Gaggia 74507BCN Classic, Krups EA8080 Espresseria Automatic, DeLonghi
PrimaDonna ESAM6600, the BC0255 DeLonghi coffee machine and the Krups Nespresso CititZ XN 7006.
