Topic: Melitta automatic Drip coffee maker (8 msgs / 294 lines)
1) From: MSMB
In my local trift store I just came across a Melitta Fast Brew Automatic
Coffee Maker (MEFB2B).  Upon looking at the underside of the maker I noted
that the machine provided 1450 Watts, which should be quite sufficient for
making a hot cup of coffee.  If it is true that basically all you need for
good automatic drip coffee is a brewer with 1250+ watts to get the water hot
enough and the ability to brew in 8 minutes of so this one should do the
job.   
Now, the particular one I looked at does not seem to have the front buttons
working.  When you plug it in the time of day goes on.  But after filling it
with water I pushed the on/off button and nothing happened.  I also was not
able to change the time.  So I assume the buttons on the front of it are
broken.  Or is there a special way of working and programming this machine?
If anyone has used one of these, could you please tell me if you must hold
down the buttons in a certain combination or is it just a matter of push the
"on" button and it should make the coffee.  Does anyone know if it is
difficult to repair the buttons, if they are broken?

Sounds like a project, Kewl!
Sorry I have no idea aobut the buttons but I bet the tinker types on the
list will have LOTS to say aobut this... 
First question have you ever used a soldering before? 
Do you have a few spare circuit board handy? 
Is radio shack on speed dial for parts?
If you answered yes to these questions then you can find a way!
remember reverse engnering is twice the work with half of the
thought.......
Enjoy!

As to the soldering iron; are you knowledgeable as to which end gets hot?
The problem is most likely NOT the buttons themselves but the connector from the front panel buttons 
to the control board.  It will be a flat piece of plastic with conductors printed on it and an end that is 
inserted in a plug.  These tend to get / develop a bad connection and quit working.   Cleaning them is 
not a trivial task and has maybe a 50% to 70% success rate.

Can you just bypass it by jumping the connector making it an always on
and just unplug it when not in use?

Ray, not to argue with you but, the electric here sucks, and the 
microwave continually blinks 12 o clock.... i long ago gave up trying to 
keep it at the right time.  If you are trying to do something with the 
timer then yep set the clock, otherwise the m wave works fine flashing 
noon when I nuke a quickie snack or water for the morning coffee or 
whatever.

err let me add more... unfortunately a lot of those type machines, the 
computer and pushbutton stuff is an integral part of it's workings. so 
if the buttons dont' work and you cant set the time etc... theres a good 
chance you can't work around that, it just won't really work.   Ray is 
correct that if it's a thermal fuse for the heating element, then you 
can shunt that, but might want to look in to why  it blew in the first 
place....but if the button pad is not working, you might be screwed..
Let me just add this one bit of advice... many digital panel read outsor 
pushbutton pad devices  have a flat ribbon cable that connects them to 
whatever, if it is not just hard soldered into the board, there is 
generally like a plastic plug thing type thing.. thing..... thing that 
it plugs in.... Please, resist ALL temptation as much as possible to 
unplug the cable from the board to get at the stuff below if you need 
to.....
once you remove that ribbon cable from the receptacle... a polite word 
for it,  getting it back in more often than not is like trying to unpop 
a balloon.  Don't ask how many keboards I have molestered trying to 
clean out a spilled beer or whatever :)   trust me, I know about these 
stupid ribbon cables.
good luck on your machine.

I bought it, got it working and... it is a dud.  That is, =
notwithstanding its 1450 it does not get the water hot enough.  I should =
have read reviews before buying it because according to them the problem =
is the construction of the coffee maker.  Watts along do not the coffee =
maker make.  I think the problem was the way the water went up the side =
of the device rather than right through the center.  I only paid $5 so I =
chalk it off as a donation to a good charities.
