    I am trying to repair my non-functional dishwasher and I have found a component on the control PCB that has partially burnt and disintegrated. It is a surface mount item with the markings: ST Z3M A009. It has 3 pins on one side and one longer tab on the opposite side.

    I would be very grateful if someone could tell me where to get this component or an equivalent in the UK please.

    I have virtually no electronic knowledge but to have the soldering skills to replace the component.

    Many thank in anticipation.

    It sounds like a triac. Change your search to numbers only.

    Sir mendit . . . . .

    I read the coding on the device as:

    ST electronics being the manufacturer of that device
    The actual full device number id is . . . . Z0103MUF
    The A009 is being a code date.

    This Triac unit specs out as being a 600V 1 amp unit with a gate sensitivity of 3 ma.

    Mouser has 2,906 in stock at 84 cents a copy . . .OR . . .
    do a search of UK suppliers using the full


    numbering of the part.

    Why don't you seek an advice from some good electrician.

    An electrician is probably no help. All he will do - if anything at all - is change the control board.

    Please post the Brand and Model of your dishwasher.
    That way we can be of help:
    finding the service manual and guiding you further.

    Electronic parts "blow-up" because of some reason,
    many times not just a single device with visible damage.
    Finding the reason is the way to fix,not just replacing a "blown" device.

    "no electronic knowledge"
    not a very good point to start with electronic repair...;)
