Washing Machine Won't Start But Red Light Flashing

Hello Joe. Unfortunately your case highlights why I always advise never to speculatively replace parts, especially expensive ones such as the main PCB or module. It's the single most miss-diagnosed part on a washing machine and even engineers often replace it only to find it wasn't that. The problem with such parts is you can't normally see a fault or test them, therefore you can only diagnose a faulty one if you've eliminated every other possibility or if by any chance an error code implicates it bit even then it's not reliable.

At least if an engineer has one on the on he can always swap them back if the fault remains and use the part again but buying one speculatively is a big gamble. Even many engineers will shy away from ordering one if they don't carry them because they might be stuck with it if it fails to cure the fault.

If the red light on a washing machine is flashing a set number of times, with a pause inbetween it's indicating an error code. If so count and report the number of flashes. If it's a constant flash with no pause then it isn't.
