ok i have this washing machine that a woodlouse killed my but the washing machine killed the louse for sure .but the viper chip is in question . dont see any shorts and can see the internal diode is intact . only thing i can find is r27 100 ohm resistor that acted as a fuse was burned open i mistankey replaced with 1k and was greeted to a nice smoke show and blackened board but was just soot . am thinking replace with 100 ohm and see what happens then if all fails sack the switching supply and wire in a proper supply as have lots of that shit in stock already . the board is the same as on this forum https://www.plcforum.it/f/topic/3076...segno-di-vita/. i can get actual pics in daylight . oh yes the louse had expired right across c32 that seems to go between primary and secondary on the transformer

That is hard to tell if that killed the viper or not. I did see them and others testing all right, but then be just dead sitting there. There is no way of knowing until you replace that resistor and fire it up again. -
ok the viper06h is definitely dead . replaced 100 ohm resistor then fired it up through my light bulb and a nice bright flash from the viper . i dont have a replacement and have to order min 10 of them and a 2w 100 ohm resistor .Comment

new viper and resistor soldered in and the board seems to power up fine on the bench so next job is spray it with conformal coating then test it in the machine .Comment

sweet! Unfortunately there is no other way around it. Like I said, they can do strange things. Good thing is that you fixed it!

all done and tested on a long wash . all seems fine apart from the touch buttons that are sticky . possibly an issue with damp getting in .. can just about deal with it if i can put the child lock at the right moment . otherwise the temp is forever changing itself and sometimes spin speed as well .

Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
The power supply board reference is the following: DC41-00189a
I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel... -
Hi,
I discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.
General test conditions:
- Tested with Core i5 6500 and Core I7 6700K - no difference
- Default BIOS settings, but tried also altering several memory setting - does not change anything
What is wrong:
With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)
When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST stucks after 3 Debug Codes on Code C2... -
I got a Asko washing machine that has had the flat ribbin cable sustain damage from some corrosion. I have tried to repair it but the ribbon cant sustain the repair and keep breaking. I was trying to source a new LED display but I cant figure out how to try and source one. the information on the back of the display is 13669-LED-A-A173-161007-RoHs. Its also a negative display witha 17v supply for the LED back light and the connectors are 26 pin x 2. What do i have to provide to try and source one of these?... -
Hello everyone,
I'm looking for a replacement for the red LEDs used in a Fisher & Paykel 10 kg top-load washing machine. Each LED is about 6 mm long, mounts flush to the PCB with side tabs, and measures around 1.7 V forward voltage in diode-test mode. The marking on the body is “3A56,” but I can't find any matches for that in part searches. I've attached photos to show the shape and mounting style.
If anyone has sourced an equivalent or knows a suitable replacement, I'd really appreciate your input. Thanks in advance for the help!... -
Hi,
This washing machine has power module emc18aecn1 and programmer ewx14931 914913208.
It stop after electric shock.
When i choose only spin it show 12min remaining. After 1min it start drain pump, after
second it start relay (measured 12v ot relay`s coil) that deliver 230V to power module.
This is also ~1second and then pump and relay stop. After ~2min this repeat - pump,
after it relay and both stop.
There is no error.
Can somebody help me to try to fix it?
