Ive got a 6 year old in built in de-dietrich dish washer.
its been faultless up until the last week.
in the last week its started putting a layer of crap on the glasses.
ive cleaned it all out, cleaned all the filters that stop crap going into the waste.
we always rinse everything before it goes in.
ive used dish washer cleaners on the hottest settings when its been empty.
but still im getting a layer of crap on stuff.
any ideas would be gratefully recieved
are the glasses sort of milky white?
when did you last fill up the salt thingy?
have a look here

do you have a hardwater filter in the system anywhere? it may have run out
I had to change the drain hose on ours as it was completely clogged up with limescale - is it draining OK?
salts filled up regularly - thanks for the link though
we dont have need for hard water filters.
the crap is more like beige/brown crud (im not sure what to call it)

perhaps it is from the heater element,...!
Is it actually heating the water ?
Our Bosch did the same thing, turned out to be running cold due to a fault
on the circuit board in the door.
Two days out of warranty but they honored it. Guy came to fix it, turned up
with a part in his hand and went straight to the door. Common fault I thought.
Happened again 5 years later so I took the board out, found a burnt track
on it. Fixed with a bit of wire and solder. Still going four years on.
interesting point about getting hot
didnt even consider it
will set it going and open mid way through and see whats going on
Thanks
My Bosch build in DW suddenly stopped cleaning properly and leaving crud on all the dishes it was getting warm but not hot....
Turned out to be the drain hose which was all blocked.
Sounds like back flow from the waste, if the outlet is just t'ed in to the sink drain it can back syphon if the vacum breaker at the top of
the loop dosen't work.
I found it best for the dishwasher drain hose to loop into a vertical open topped stand pipe (to give an air gap) above the normal level of water
in the sink
Our old dishwasher started playing up with not finishing cycles, and not cleaning as expected. We ran loads of cleaning cycles with all the latest
chemicals, but nothing seemed to fix it, so we ended up going out to get a new one.
As i was removing the old washer i pulled off the waste hose that goes from the dishwasher into a T piece below the U bend from the sink. The pipe is
about 30/40mm? with all the fat, and build up of scumm on the inside the diameter of the pipe had been reduced to about 10mm 
no wonder it
was playing up. We could have gotten away without replacing it it i had found that out!
The new dish washer was a much better model though, and didnt cost too much 
Perhaps you are not being stern enough with her?

OK its definitely getting hot so its not that.
I will try taking the waste pipe off tomorrow and check that.
Thanks again
