A GE dishwasher is typically cleaned with a store-bought solution specifically engineered for dishwashers. The process usually consists of placing the solution inside and running the appliance through the dishwasher cycle specified on the package labeling.
The seal at the bottom interior of the door should also be checked for particles of food. Any debris found should be removed prior to running the dishwasher cycle; a surface cleaner with bleach can help to remove tough remnants. It is also wise to check the bottom center drain for any obstructions that need to be removed. Frequent cleaning of a dishwasher can extend its life.
