F-12 keeps flashing in the display screen, what does it mean?

12:24 probably means choose 12 or 24-hr format.

There are two ways to set the clock on your coffee maker. 1- When you initially plug in the coffee maker, the unit will beep and "12:00" will flash on the LCD display for a few seconds. Press immediately the h/min button (o) to set the current hour. If "12:00" starts to flash, press the PROG button (n) for a few seconds until the "12:00" flashes again. Then press the h/min button (o) to set the current hour. There are AM and PM indicators on the top right side of the LCD screen. To set the current minutes, press the PROG button (n) and then press the h/min button (o) until the correct minutes appear on the LCD display. After 5 seconds, the unit will beep and the time will stop flashing. 2- At any other time, you can set the clock or change the set time by pressing and holding the h/min button (o). The unit will beep and "12:00" will flash on the LCD display. Use the h/min button (o) to set the current hour. There are AM and PM indicators on the top right side of the LCD screen. To set the current minutes, press the PROG button (n) and then press the h/min button (o) until the correct minutes appear on the LCD display. After 5 seconds, the unit will beep and the time will stop flashing. Notes: Your clock has now been set and will continue to keep the correct time, even after the coffee maker has been shut off. Unplugging the coffee maker or a power failure will reset the clock to 12:00 AM. Repeat the instructions above to reset the clock

It's not clear exactly what you mean. Is the laptop power flashing on and off? Is the screen display flashing on and off? Is the internet flashing on and off? Please provide more details .

Code 12 doesn't need fixed. When you begin to test codes you will get the code 12 but that is just telling you that it is in diagnostic mode, it will flash the code 12 three times, then after that it will flash all stored trouble codes. After all stored trouble codes have been displayed, the ECM will repeat the process( so getting code 12 again means you have reached the end of the stored codes list) If it displays code 12 three times and then displays code 12 again , it means you have no problem codes.

When you say flashes, is it like portion of the screen flickers?

If the flickering/flashes starts in Dell screen just right after turning on the laptop, when you see the Windows logo or just right after you log in to windows?

Try connecting your laptop to an external monitor then toggle display. To toggle the display to external monitor you can try holding down keys such as the function keys.

If the problem persist from the external monitor it means the problem is the motherboard or the video/graphics card.

If no problem from the external monitor this means laptop LCD and LCD cable needs to be replaced.

Hope this helps.

hotpoint f12 means water is off.????????

hi my hitachi fridge is giving error fo 12 what happend with this

A blinking flash symbol usually means the flash is trying to charge but can't due to weak batteries.

Hi.

12 flashes means "Incomplete combustion". The code is prompted when the flame turns off because of a problem.

Check filter, check gas pressure and thermocoupling. Those are the problem that commonly trigger the code 12 error.

Here a manual.

Here Fixya thread on the problem.

1) Do a hard reset = leave unplugged for 12-24 hrs , then
try again.......................................
2) What does "until the remote is disabled" mean ??
