Samsung EcoBubble (WW80J5555FX) - AC error and power issue

Recommended Posts

Wondering if any can help on the following:

My Samsung washing machine flashed up with an "AC" error code yesterday - manual tells me "check communication between the main and sub PBAs" which isn't much help. After the error code the display panel also froze, not allowing me to power off the machine or do anything. Unplugged and left it for a short period, turned back on last night and seemed to be back to normal display. 

Attempted another wash this morning, was fine for 20mins then same error code and frozen display. Unplugged again at the wall, however this time the machine wont power back on at all, nothing lights coming up on the display, no start up sounds etc. 

Had a look at the PCB and all connections and wires seem fine, no obvious external issues from visual inspection (but im no expert). I'm thinking the best thing to do is order and replace the PCB and see if that resolves the issue, worst case if it doesn't then I just return the part and go down the more expensive route of an engineer or buy a new machine. Machine is outside of the warranty window. 

Thought worth checking if anyone has had similar issue with this model, and anything worth me trying/ checking before replacing the PCB?

Any help much appreciated, thanks in advance!

Hello Jamie. It sounds like you've done everything you can. You can't return the PCB if you fit it and it doesn't fix the fault so that's a massive gamble. I'd be amazed if any spares site accepted one back that had been opened. The fault could be on the PCB, or control panel, or it could be a connection or wiring fault somewhere between the two. Faults like this are not really for DIY because you really need to try replacing things and hope to fix it by process of elimination, which is not possible if you are having to buy the parts and can't return them.
