Most cleaning problems are caused by the dishwasher not getting enough wash water, so call upon Dependable Refrigeration, LLC. to help maintain the water-inlet valve. A defective water-inlet valve will need to be replaced. However you can help extend the life of your dishwasher with a few simple tips. Twice a year, lift out the strainer and scrub with warm, soapy water. You also can help dissolve mineral deposits and soap residue by placing a small container filled with one cup of distilled white vinegar on both the top and bottom racks, then run a regular wash cycle. Remember to always plug your dishwasher into a grounded outlet and do not use an extension cord. Talk with Dependable Refrigeration, LLC. customer service to help arrange for a service agreement that will extend the life of your valuable appliances!
