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.

    will power on but not brew and yes, it is clean

  • potr Mar 15, 2008

    My delonghi dcm485 will just stopped working even though the power is on. I can not clean it as suggested because no water is being sucked from the reserve tank to either clean or brew. I have also tried reseting to no avail.

    Mine is about 18 months old (out of warranty). 2 days ago it worked fine. Yesterday the light went on but no brewing!

    have power to the coffee pot but the coffee will not brew, no water being pumped out of the reservoir

    My pot will turn on but it will not brew, nothing happens. Of course my warranty has run out. Should I just throw the coffee pot out.

  • jhbmcunn Mar 21, 2009

    Ok, my Delonghi DCM485 stopped. It won't empty the resevoiur, it won't start the brew, just nothing. I've taken it apart, the fuse (I'm guessing this is the thermal fuse (circular ceramic shape attached to the heating unit) showed 0 ohms across, so I am assuming that it is good. My heating element shows about 16 ohms across it, so I'm guessing here that some resistance is better than nothing. My pathway from the input and the out put of the element is clear. There isn't a pump unit in mine just an output to the top of the brewer. So my question is, what should be showing across the element? More resisitance? My guess at this point is, since this thing doesn't use a pump unit, it relies on heat to cause the water to rise to the top of the brewing unit, and without the heat, no brew. Any insights would be helpful, as I never made it through Delonghi service school..

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

    I toasted this morning to you Dorito88 : ) You saved me a ton of money

  • fjd3 May 20, 2011

    Dorito88 -

    It works - it makes coffee - you ROCK.
    I just went in and replaced both fuses - don't own a volt meter - never done anything like this before.
    BANG - fixed.

    Thanking you.




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.

Unable to remove infuser, no warning light, reset multiple times, brews coffee fine

You should go to test mode and try moving infuser up and down to position when you can take it out it needs some skill of timing. After that you need to disassemble infuser completely clean it up and lube with special food grade lube. Also there could be a problem with transmission kit that cause this problem.

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

What does it mean to descale my tassimo? the yellow light is on and the screen keeps saying "descale". thanks

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.

Delonghi bar 18 oump driven esp maker won't pump water

It may be a stupid suggestion but have you checked the strainer in the reservoir? It Could be blocked. And if you haven't removed the brew head sieve recently? It could be gunked up.

For cleaning it's best t use citric acid packets sold in stores as it hurts the metals inside the tank the least, but in a pinch you can use vinegar, although it's much more corrosive and could hurt the machine.

When using a cleaner remove the brew head sieve, as a lot of junk will collect and can block the sieve, with resulting no flow for brewing.

Hope this helps!

I'm looking for Elektra S1 Owner.s manual

if you have 2 gauges, one shows from 0 up to 3 bar second from 0 up to 16 bar.

  1. the gauge o - 3 shows steam pressure and it should be from 1.1 up to 1.5 bar
  2. if you have second gauge you look it during brewing coffee, it should be from 7 up to 9 bar(it shows the pressure of pump.
anyway becouse it is old machine you should compare the gauge with new one(ehamle for the steam attach to steam pipe one gauge and live valve open) than you will know if it is showing true values.

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.

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.
