Program rival coffeemaker to turn automatically in the morning.

Fill it with white vinegar, let sit overnight. Turn it on in the morning and Jerry it run with the vinegar in it. Should dissolve the deposits that form in the heating elements.

I know this sounds like a pain but it takes a while to get that silly light to stop.
If you have problems call the 1-800 number below.
Decalcifying your MR. COFFEE® Coffeemaker Minerals (calcium/limestone) found
in water will leave deposits in your coffeemaker and affect its performance. It's
recommended that you regularly remove these deposits using MR. COFFEE® Cleaner
or vinegar. MR. COFFEE® Cleaner is available at many retail stores or by calling the MR.
COFFEE® Consumer Service Department at 1-800-MR COFFEE (1-800-672-6333).
1. Follow package instructions to prepare one batch of MR. COFFEE® Cleaner. Pour the
mixture into the water reservoir. Before decalcifying, remove the water filtration disk
from the machine.
NOTE: 4 cups or 20 fl. oz. of undiluted, white household vinegar may be used as a
substitute for the cleaner.
2. Place an empty MR. COFFEE® 10-12 cup basket-style paper filter
or MR. COFFEE® permanent filter into the filter basket and slide
the brew basket in place.
3. Place the empty decanter back in the unit.
4. Press the CLEAN button until the CLEAN indicator light turns on
(Figure 9). For your convenience the cleaning cycle is automatic.
The entire cycle will take 45-60 minutes to complete.
During the cleaning your coffeemaker will:
a. Slow brew approx. 3 cups of cleaning solution.
b. Pause for 30 minutes (the CLEAN light will remain on to alert
you that the process is active).
c. After 30 minutes, your coffeemaker will brew the remainder of the cleaning
solution.
d. When complete, the CLEAN light will turn off and your coffeemaker will turn off.
5. Discard the cleaning solution and rinse the decanter thoroughly with clean water.
6. Fill the water reservoir with clean, fresh water.
7. Place the empty decanter back on the coffeemaker.
8. Remove and discard the paper filter used during the cleaning cycle. If a Mr. Coffee®
permanent filter was used during cleaning, remove it and rinse it thoroughly before
replacing it in the filter basket.
9. Begin brewing and allow the full brew cycle to complete.
10. Repeat steps 5 through 9 one more time.

Sorry someone has not responded sooner.

Try this and let me know if it works - plug the coffeemaker in, turn the function knob to BREW, and then press all 3 buttons in the center of the coffeemaker (the 1-4 button, et, etc) and hold them for a few seconds. Let me know if the clock display comes back on.

You have to use the "Auto-Off" feature, which is located on the same button as on/off:
The automatic shutoff time (ASO) can be
programmed to shut off immediately after
brewing (0:00) or up to 4 hours later. The
default shutoff time is 2 hours.
Press and hold the On/Off button to display
current shutoff time. To change the preset
time, press and hold the On/Off button until
the red power light and LCD display begin to
flash. This signals that you have entered the
Set automatic shutoff mode. Set the time
you want coffee to begin brewing by
following the instructions in “Entering Time
Set Mode.”
When the coffeemaker shuts itself off, two
tones will sound.
NOTE: Automatic shutoff may be
programmed either before or during coffee
brewing. If you program the auto shutoff
time after brewing is completed the unit
will automatically account for elapsed time.
For example, if you set the auto shutoff for
40 minutes and 25 minutes have already
elapsed, the unit will shut off automatically
after 15 minutes (40 minutes minus the 25
elapsed equals 15 minutes).

You have to set the coffemaker to AUTO-ON for it to turn on at a set time in the morning. The PROG function is merely to set the right turn-on time. Once this time is set, you must switch the coffeemake to AUTO-ON.

Turn the function knob to CLOCK, then press and hold the HR button for a few seconds and set the hours. Then press and hold the MIN button for a few seconds and set the minutes. Remember, the LCD will show "PM" if it is on PM, but it will not show anything if it is on AM. Once you are done setting the time, don't forget to turn the function back to AUTO-ON, or your coffeemaker will not brew at the set time in the morning.

Reset the coffeemaker by unplugging it for 20 minutes or longer - don't skimp on the time left unplugged.

Then plug the coffeemaker back in, reset the normal clock. Remember: It will display PM if it is on PM, but nothing if it is on AM.

Then hit the Program button. Hold in the "Hours" button for a few seconds and set the time you want the coffeemaker to go off in the morning. Hold in the "Minutes" button for a few seconds and change the minutes. Then hit the Program button again.

Now turn your coffeemaker to AUTO-ON - it will now go off at the set time.

to prgram the automatic operation, press the automatic buton until the green pilot light begins to flash. The time "12:00" or the previously programmed time appears on the display. When the green pilot light begins to flash, release the button and press the hour and minute buttons until the correct shows; ensure the hours are am or pm. After programming is completed, the green pilot light will go off after 5 seconds.

My coffeemaker makes the coffee just fine every morning, and we leave it on for 2-3 hours and then it turns off automatically , but later it leaks back to the water reservoir and then out the bottom all over my cabinet. What is wrong?
