How can I fix my diplomat dishwasher model ADP 8132?

THERE WAS A LEAK AT THE INLET VAVLE (cracked plastic body) REPLACED WITH A NEW ONE.NOW THE HEATING ELEMENT DOES NOT SEEM TO BE WORKING.THE CONTROL DIAGNOSTIC PANEL INDICATES "UNABLE TO TAKE IN WATER" ALTHOUGH THE WATER IS BEING PUMPED OUT. COULD IT BE THAT I HAVE CONNECTED THE WIRES THE WRONG WAY AROUND WHEN I REPLACED THE INLET VALVE? PLEASE HELP !
