Question

HI! MY NAME IS MARK AND I AM HAVING PROBLEMS WITH MY FRIGIDAIRE MODEL # FDB710LCB0/SERIAL # TH51153536 DISHWAHER.
THE PROBLEM: IT DOES NOT COME ON AT ALL LIKE THERE IS NO POWER TO IT. I HAVE CHECKED THE BREAKER AND THE ELECTRICAL CONNECTION AND THERE ARE NO PROBLEMS AT THOSE POINTS. ALTHOUGH FOR A BRIEF MOMENT LAST NIGHT IT DID COME ON AND THERE WAS A "HUMMING NOISE AT THE DRAIN PUMP LOCATION (IT SOUNDED REALLY BAD) THEN IT SHUT DOWN AGAIN AND NOW IT WON,T COME ON AT ALL. ANY IDEA'S ON WHERE TO START AND WHAT PARTS I WILL NEED TO REPALCE?
THANKS, MARK DOTSON
