Hi,
I am trying to repair a control board for my brother's dishwasher, the transistor driving the detergent release solenoid has been blown by failure of the solenoid.
The solenoid has been replaced with a new unit, tested and confirmed good.
The transistor has a hole blown in its casing which has obliterated some of the ID numbers & letters. It is a TO-92 package from ST MicroElectronics .. I can still see their logo and the characters 'e3' in a circle.
Comparing it to similar units on the board I can tell that before the blow out there were 2 rows of 4 characters ..Only the right hand characters remain ..
_ _ ? 1 ? = partial character may be 8 or S
_ _ ? S ? = partial character may be 6 or G
The batch number (?) is also visible lower right and is 849
A bit of a puzzle for sure .. I hope some one here can help identify the component and save my brother the £100 a new programmed control board would cost..
