    Hello, I have a Siemens SE24N860EU dishwasher. The elements that I have already tracked are probably damaged, unfortunately I cannot find the schematic and decode what kind of resistor it is.

    The questions are as follows, what is the resistor visible in the photo? Does anyone have a schematic of this board? (AKO 704226, BSHG 9000.115.609, PRG 710573-02, AKO 710569-05)

    Usually, in addition to the 100? resistor, the IC must be replaced :D

    The dishwasher refused to cooperate again after about 5 work cycles. The symptoms are identical, i.e. no reaction, the display remains black, etc. Maybe this LNK340GN has died again a little strange? Visually, everything looks ok and the resistor and LNK340GN.

    Visually, it could all look good. Use the meter to measure the resistor and LNK340GN.

    I measured the resistor and it was dead, I can not check the IC. Now it works again, we'll see how long ...

    So you probably did not give the same as the original politically correct :D

    I gave 100? / 3W as you wrote to me in the second post :)

    Dear friend rolnikszukazony These are not the values I had in mind (the data is correct) when I wrote the previous post, and this is what was written about it ... :D

    The resistor burned out again. Where to look for the cause?

    The resistor burns most often when the LNK is burning. So if you replace the resistor and it will burn out immediately - LNK to be replaced.

    LNK usually burns from overvoltage. First, check that the fuse path at the varistor is complete.

Topic summary

The discussion revolves around a Siemens SE24N860EU dishwasher experiencing issues with a damaged board, specifically focusing on resistor identification and the absence of a schematic. The user initially inquired about the resistor visible in a photo and sought a schematic for the board. Responses indicated that a 100Ω resistor and the LNK340GN IC are critical components, with suggestions to measure their functionality. The user reported that the resistor had failed, and after replacement, the dishwasher temporarily resumed operation. However, the resistor burned out again, prompting further investigation into potential causes, including the possibility of the LNK340GN failing due to overvoltage. Recommendations included checking the fuse path at the varistor to prevent recurring issues.
