Hi Kay - A yellow stain or ring under the heating element is a build-up of minerals that have come off the heating element during many dishwasher cycles. This can be removed by wiping it with a mild cleanser and a towel. An overall yellow staining is probably caused by minerals from the household water supply (or coffee or tea stains), and can be cleaned using a citric acid treatment. Citric acid is available in liquid or crystal form. GE Appliances recommends the crystals because they will remain in the detergent cup until it is time to dispense the product, while the liquid is likely to run out before the detergent cup opens. Citric acid crystals are sometimes called "sour salt" and are available at some drug stores and most grocery stores in the canning or spice section. GE Appliance Parts also stocks Citric Acid Crystals as part number WD35X151. Purchase a part online at GEApplianceparts.com - Citric acid can be used in both plastic and stainless steel interior dishwashers. Do not place silverware, aluminum items or other metals in the dishwasher during this process to avoid tarnishing those items. Dishes or glasses with "patterns" should not be left in the dishwasher when doing a citric acid treatment. Some "patterns" can be damaged or washed off.
