Good day!!!
if the c.p is submerge to water you need to clean it buttons and board...
try to open the cover of your c.p then go to the button or keypad printing board.. get cotton buds with alcohol..and gently wipe it to the printed board and even the contacts of keypad..
after that also try to clean the board using contact cleaner and brush..
Thank you and don't forget to rate my answer and write a testimony..
