dishwasher?

I have a diplomat adp8322 dishwasher. I have got problem e7 on display. i have taken off back and at the bottom there is a burnt out coil type thing. It has a wire from that which goes into what looks like a relay. on the little black thing is the part no pa244l/na and on the other side is LN. Does anybody know where i can get this part from. many thanks
