LDF6920 D/W Not Getting Hot Enough

[nvffgt343]

In the last week or so, my LDF6920 dishwasher has not been cleaning well.  Finally realized that it doesn't seem to be getting hot enough.  Usually, if you open the door right after it finishes you get a steam bath, now the water seems tepid at best.
Doesn't seem to be an issue with the incoming hot water as its as hot as it ever was.  I'm also not getting any error messages, such as the "Heater Circuit Failure" discussed on page 21 of the manual.
Anybody seen anything like this before?  Any suggestions gratefully appreciated.
TIA!

most likely a broken orange wire to element behind front panel, where door opens putting stress on wiring.

Interesting...When you say front panel, do you mean the door itself?  Can I just replace the wire with one of the same gauge or do I need to replace the element?  Any diagrams or other suggestions would be gratefullt appreciated!

 Should be able to take a door panel off and check the wiring behind panel. May be the heater. Most likely a broken wire. I'll see if I get a manual for it.

Thanks for the schematic!  I'll pop open the door and see what I find.  I noticed there are fuses on the heater circuit...is it possible that one of them have blown?

[bigbuck]

Yes its possible, you can check fuses with a ohm meter
