I've been washing dishes for YEARS now . . . you'd think I would know what I was doing! Last week, my dishwasher started pouring water & suds out the front of it. I promptly turned it off, cleaned up the mess & called the home warranty to get it fixed. One week later, the repairman showed up to fix my broken dishwasher. He listens to what happened & said, "You used dish soap instead of dishwasher detergent." I was adamant that I didn't do that but he proceeded to tell me that the only possible way to have suds is with regular dish soap.
He went on to ask if I wash the dishes with dish soap before putting them in the dishwasher. Well, of course! That's how my mom taught me to do it . . . you don't put dishes in the dishwasher without washing them first! Well, apparently if there is even a little bit of the dish soap residue on the dishes when you put them in the dishwasher, it can cause out of control suds during the washing cycle which will then proceed to pour out of your dishwasher!
The answer: don't wash your dishes with dish soap before putting them in the dishwasher! If you do & have suds all over the place, pour a small amount (1/4 cup or so) of cooking oil into the water in the bottom of the dishwasher & start it up again. The oil will cut the suds & help them to wash out!!!
I'm just amazed that after all these years of doing dishes the exact same way there is all of a sudden a problem . . . but after a $60 service call fee, I've learned my lesson!
