This is what happens when your husband tries to be helpful and do the dishes.....with the new environmentally-friendly DISH SOAP we bought. Obviously, it wasn't friendly in this environment! After the cleanup, I tried to explain the difference between DISH SOAP and DISHWASHER DETERGENT, but the look on his face told me it didn't sink in. Isn't he sweet for trying, though?!
FYI....if this ever happens to you, stop the cycle, drain it, pour a massive amount of vinegar (or a few cups if you follow directions) in the bottom of the dishwasher, add a "layer" of table salt and turn on a regular cycle. After a couple minutes, check it. If it continues to make excessive suds, add more vinegar and salt!
