Why am I getting no power?

Press the start button and nothing happens - no lights, no nothing.

Prior to this, it was working fine. Samsung front load wf0500nce.

This is what i've done so far...

Using a multimeter, i checked...

1. Socket
2. Plug fuse
3. Power at the plug cable connector (which connects to the noise filter)
4. Power by back-probing the other connector of the wire that goes to the washer at the noise filter.

What else can i do to find out where the problem is?
