A few buttons on my k850i keypad wont respond ie 2,3,cancel button and call end

CHECKING KEYPAD OPERATION
A rapidly blinking LED over one of the keys of the keypad (or sometimes a "dead" keypad/console)
To determine if the control or keypad is faulty, do the following test:
1. Unplug dishwasher or disconnect power.
2. Open the dishwasher door.
3. Open console and disconnect the keypad ribbon connection from the control (at P1).
Make sure all other connections are made.
4. Put console back together. Do not close the dishwasher door.
5. Plug in dishwasher or reconnect power.
6. Wait 5 seconds.
7. Close dishwasher door.
8. Monitor the control's response:
If the control is OK (no longer sees shorts with the keypad unplugged),
it will respond by turning on a Drain Motor for 2 minutes.
Check and/or replace the keypad if the control responds OK.
If the control is not OK (still sees shorts with the keypad unplugged),
then the drain motor will NOT respond and will remain off.
If no response, replace the control.

The solution is to troubleshoot the microwave as explained below.

1 Check the power supply. Make sure the microwave is firmly plugged into a working electrical outlet and that your wall outlet is active if your home uses outlets controlled by a wall switch. Check your home's fuses or circuit breakers to ensure they have not been tripped. Without power the microwave will not respond to any input.

2 Make sure the parental lock is inactive. Some ovens, like the one shown in the image above, feature a keypad lock to prevent children playing with the controls. Most keypad locks can be cancelled by holding down a button or combination of buttons for a few seconds.

3 Make sure the door is firmly closed. Some microwave ovens will not allow any control panel input if the door is open.

4 Remove the microwave from the power, wait 10 seconds, then plug it back in. This will reset the microwave oven if there is a temporary problem with the software.

5 Press the "Stop/Cancel" button several times to cancel the current operation and return the microwave to standby mode. Re-enter your cooking instructions using the keypad as usual.

please let me know the outcome..

thanks.

Hi, it's the keypad IC or the keypad itself. So you can check the keypad if there is dirts that is stopping the keypad from working. Or the keypad needs to be replaced.

After checking the keypad if the keypad still did not solve the problem,
You will have to replace the keypad IC inside the board of the phone.

Take care. .

Hello,

About the damaged keypad, i would sugest that you buy a new keypad, it does not cost much. Using glue will end up damaging your phone.

About the phone freezing, you might consider uninstalling some applications to free up space in your phone, or perform a factory reset to correct all the errors in the phone.

If that does not solve the problem, you might have to take it to a service center for a firmware update.

Thank you for using Fixya,
Kenneth

Perhaps the connection got clog up and mixed up. Try opening your front phone cover and wipe it.

Consult your owners manuel for turning off the sabbath mode feature.
try to remember the whole f1 code. if it was f1-1 it could be a temperature problem
if it is f1-4 is could be a shorted keypad
the control pad could be locked out as well. try holding the cancel key for 3-5 sec to see if it unlocks the control
