HELP!!
My dishwasher is not cleaning my dishes! Can the element be out? It's just 14 mo. old. Dishes coming out greasy as if not washed. Thank you!

Yes the heater could be shot.
If it is drying the dishes properly then odds are the heater is OK.
Remove the wire from one side of it and check it with a meter. They are usually between 20 to 30 ohms.
Check that it is getting voltage (120 volts) when it should during a wash cycle. Your manual should tell you which cycles/options include a temperature boost.

Check that the unit is filling with water correctly, most units fill to just under the heating element.

As Drags1998 said if your water temp is high enough and you are using a good detergent the unit should be able to do a good job without a temp boost. Personally I like the good old fashioned granular type.
