Did you measure it?

Ideal brewing temperature is between 195°F and 205°F
Is There a Perfect Coffee Brewing Temperature? According to the National Coffee Association, the ideal water temperature for extraction is between 195°F and 205°F, which is a little below the boiling point of water - 212°F. What's handy about this temperature range is that it works across all brewing methods.

The adjustment of the economizer for regulating the delivered water temperature is made by the installing service technician.

* You will need to program groups again.
* I'm surprised I did not record and upload a programing video *sigh*
Oh well, somebody did it already:(check at 3:57 on the following vid)

* Set up each shot with a filled portafilter (for the appropriate dose setting. Single for single, double for double, etc.)
* Press and hold "Stop" button till it light (and/or beeps). Release stop button
* press and HOLD the appropriate dose button (within 5 seconds or it cancels out)
* Watch the coffee dose as it pours out into cup or a shot glass (for accuracy)
* Release the dose button just before it hits the desired amount. You may have to do this several times to practice.
* Continue with setting the dose on the other settings (long, double, etc.)
* Note; you can set the "least used group" as in a 3 or 4 group head machine with specialty doses. Like a triple if you have the proper portafilter for this shot. Or an "American" long shot (though I don't recommend running 6-8 oz of water through a single coffee dose. Though I have found some shops using drip coffee through a triple basket and very long dose to fill mugs. They didn't want to get a regular 12 cup brewer.)
* There are other dosing tricks like copy over to other groups. But I've found that setting each group and dose is good practice. (and I have to do it several times a day as a Espresso Tech.)

M29 is a semi automatic machine. Wiring is straight forward with the normal variance for single phase and 3 phase. Sorry i don't have a digitized diagram on hand. Maybe later. Dosing, is done with the control board which will need replacement if its not working.

Press and hold any Group stop button until beeping, then all the button will copy what you press. Hit any stop button to leave program.

should be the same method unless the stop button needs replacement. The stop button is one of the most often used (abused) buttons and frequently needs replacement.

Sounds like the problem is in the keypad.

1-Cover the buttons on offending side (paper and 1 min to do)
2-Reprogram one side to give it a short dose. (5 mins to do)
3-remove power to group valve (screwdriver and 20 mins to do)

Note if you do remove the power, please leave a note for the crew as they will probably call a technician in to 'repair' it again.

This is for you....I hope this M29 will do what you need...I called he Cimbali 1-800 number and this is all they had...I tried...been working on this one for about an hour...found one in Russian....Italian...Spanish....but when I translated them and tried to paste them they came in both languages and intermingled somehow....wierd....but here you go ....I hope this helps...good luck and thanks for rating my effort....The Fang

P.S. any probs...call 1-800-724-6225 and speak to Trish. Thats 1-800-Cimbali. Take Care

Remove the 3 screws on the side of the bell they might be bolts or allen wrench screws. That will give you easier access to the screen and screw(make sure you have extra screen and screws).
