Malber doesn't even turn on.

Clight16 is very likely to be correct. I repair Malbers (in the Wash. D.C. area) and have found door switches to cause these symptoms 90% of the time. BUT, that doesn't necessarily mean replacing the switch. Here's how to test: First, check out the little square hole where the door latch (on door) fits into the machine. You'll see a white plastic "frame", and behind it, a black plastic piece that slides to the right. We'll be sliding that "slider" a little later. OK. Turn machine off (if it's been on). Wait about 2 mins until "safety latch" disengages. (Don't force handle - it can break!). Open door. Set top right knob to "Off" position. Press "Start" button (power on). Turn top right knob to "Beginning of wash cycle". Because door is open, nothing happens - yet. Finally, using a small screwdriver, or other thin object, slide that black plastic "slider" over to the right (about 1/4 inch). Don't be afraid. There is nothing anywhere back there that you can hurt - or that can hurt you. It's totally safe! That simulates the door closing and the metal latch forcing the slider over. My hunch is, the machine will start working (filling with water). If so. you have a simple (and free) fix. The problem is: the metal latch is not forcing the "slider" over to the right far enough. To fix: You need to "allow" the latch to move a little further to the right. To do this, you'll enlarge the hole (on the back of the door) the latch protrudes through. The square hole is sized to stop the spring-loaded latch in the exact right spot. Press the latch back, and file (or scrape) away a little plastic on one side of that little square hole - so when you release the latch, it snaps over a bit farther than it did before. You only need the latch to "lean" over a LITTLE farther (1/16") so only remove 1/32" of plastic. That should do it. And may God bless.

Sounds like a door switch.
