If you have a dishwasher that is oversudsing, it is normally due to using the wrong type of detergent. If you mistakenly use a hand wash detergent it will create a huge amount of suds and pour out of the front door. If that happens, you can neutralize the suds by pouring olive oil directly onto the suds. Shut the door of the dishwasher and continue the cycle. The olive oil works like magic and breaks down the hand wash dish detergent and stop the unit from oversudsing.
