Recently..I changed the drain pump on the machine.

Now ( month later...) the system will not power up..I can unplug it..and sometimes..when I plug it in..I can hear a click on the secondary control board (to the top right of the machine)..but after a few seconds..the power goes out.

My question is how likely is it that the maincontrol board (on the front of the machine with the selections) is faulty. If I unplug that from the secondary board...and plug it in..it will power up for a few seconds..and then the power goes away.

What would be the best diagnostic tests for this. I have a multi-meter..but am not very well versed on its use..

Any insights/help would be greatly appreciated.

thanks
