    Hi,

    I have a quooker water heater in my kitchen. I was on holiday last month. When I came back I found that the water heater is not working. On inspecting, I found that water has leaked from the tank and caused a short circuit in the PCB. I would like to know how can I perform troubleshooting to identify the failed components and then if it can be repaired? See pictures for details

    I can turn ON the quooker and it seems to work but after some time the LED flashed 4 times which indicates an error in the PCB

    I am a newbie in electronics and only have a multimeter to do any diagnosis.

    thanks in advance IMG_5571.jpg

    New parts to the damaged area.
    Not a lot one can do with what you have there as far as I can see.

    Thanks but how can i check which components of PCB (relays, resistors etc) are blown ? First i was thinking there must be a fuse that is blown in case of short circuit but i dont find any in the board

    What makes you think there is anything blown on the control board?
    From the looks of it , it's been a bad connection on a high current load that has taken out a connector.
    That in turn appears to be driven via a relay (output drive is isolated from the other pcb coponents) so my guess would be, board is more likely than not, ok.

    Light reflections are letting me see that . . . . .That board seems to have a good sprayed on conformal coating except possibly / likely directly UNDER the IC's and relays. A drop of water hiding there can take days to evaporate internalward.
    If my situation, I would be warming up my oven to 250 and taking that board and submerging its bottom inch into a tray of 70% iso alcohol . . .or vodka.
    Then do a heavy and forceful swishing around in it.
    Then you transfer it to that warmed up oven to do two or so d e e e e e e p drying cycles after the oven is turned off.
    When you repeat the heat again after chill down.
