dishwasher?

Could be an element problem, wiring fault or a control board fault. To get at the element you need to remove the lower kick panel on the front, the top panel then remove the right hand side panel. The element is a flow through type, looks like a metal tube with a hose connected either end. The last 2 times I had no heating on that model it was the control board. The relay for the heating was burnt out. So may pay you to look there first.
