Full safety notes below<\/a><\/p>\n\n

What is the diverter valve?<\/span><\/h2>\r\nThe diverter valve assembly is responsible for directing water flow between the various spray arms in your GE dishwasher. Over time, debris can get lodged in the valve, preventing it from switching water circulation properly. You may notice that your dishes are coming out with food stuck on them, even after a full wash cycle. This is a telltale sign that the diverter valve needs to be replaced.<\/span>\r\n\r\nDoing this repair yourself is a simple job that can save you the cost of a service call. With some basic tools and safety precautions, you can have your dishwasher cleaned like new again. We'll provide detailed instructions for removing the old diverter valve and installing a new replacement part.<\/span>\r\n\r\nBefore getting started, make sure to turn off the power to the dishwasher at the breaker box. You'll also want to shut off the hot water supply line underneath the sink. This will prevent any water from leaking out when you disconnect the hoses. Have some towels or buckets handy to catch residual water in the lines.<\/span>\r\n
