WIXXE 127 indesit control board

Hi,

On these Indesit/Hotpoint boards, a designator starting with "Q" is often a transistor or triac, and when it sits close to the door interlock connector it is very commonly the switching device that drives the door lock circuit. However, without the exact board layout or a clear photo, I would not want to guess the exact part number.

A few checks to narrow it down:

1. Isolate the machine from the mains before removing or inspecting the PCB. 2. Look very closely at the PCB tracks from Q14: - If one side goes to the door lock connector J4 and another to a small driver resistor/opto circuit, it is quite likely a triac. - If it feeds a relay coil or low-voltage logic path, it may be a transistor instead. 3. Check the package style: - Small 3-pin SMD device near a mains load on Indesit boards is often a triac used for a valve, pump, or door lock output. 4. Inspect the surrounding parts: - Burnt gate resistor, track damage, or a failed door interlock can take the driver device out with it. - If the door lock itself has gone short circuit, simply replacing Q14 may result in it failing again. 5. If possible, post clear close-up photos of both sides of the PCB around Q14 and J4. That usually allows the part type to be identified from the track layout.

If the board damage is severe, board repair may be uneconomical unless done by a PCB repair specialist. For any live electrical testing or board-level repair, use a qualified engineer.
