Hi Dirty Dish gang.
After having 2 appliance repairmen here, I now have the latest scoop on our dishwasher problems, $200 later!
Los Angeles IS currently having hard water issues. Also, all the new cleaning gels etc. are actually a cause of our dishwasher problems.  
So, here is what we need to do:
1. Use Cascade POWDER detergent only.  Make sure is is just "plain" no "scented" or "complete"  or gel, etc. (I have tried a phosphate free powder and gel and this is a cause of our problem as well!) 2. Use Jet Dry in the dispenser (set it to a 2-3 opening) 3. Make sure water is at least 120 degrees 4. Only run dishwasher on "normal" setting.  All others just run it longer, hence causing more water stains. 5. Do not pre-wash dishes! You can knock of chunks with a "non" soapy brush, but don't rinse (the oils actually help to clean the dishes) 6.  Do not wash sponges in dishwasher.
Acid Wash: The repairman just gave my washer an Acid Wash today. It says it is an acid derived from lemon, I got mine from Carters appliance in Torrance, CA for about $19. I am to run a normal cycle with the above mentioned Cascade after this "acid cycle" is finished.
If you are still having problems:
Monthly maintenance: Glass Magic: Buy a box of Glass Magic (near the Cascade)  Use 1 Tbsb in main detergent compartment of dishwasher along with the Cascade, till washer starts working again. White Vinegar: You can run an empty dishwasher with white vinegar once a month.  Fill a bowl with 2 cups vinegar and place on bottom rack.  Then run as a normal cycle...this allows vinegar to disperse slowly.
So far it seems to be working.  Good luck.

I bet your clumps of soap began with the beginning of the use of a different DW detergent powder.

Try this (trust me) Go buy a box of brand name Dishwasher powder (e.g. Electrosol or Cascade) Use it for two loads of dishes and report your results back here. OK?
