Dishwasher Repair and Maintenance<\/h1>\n

You\u2019ll have to unhook several wires, so always begin by turning off the electrical power to the dishwasher at your main panel. Turn off the water supply to the dishwasher as well. Usually the shutoff is at the hot water supply line under a nearby sink. The inlet valve is usually mounted on the underside of the dishwasher near the front.<\/p><\/blockquote>\n

    Save money doing the dishwasher repairs yourself<\/h2>\n

    Do your dishes come out spotted and stained? Have you noticed a puddle of water on the floor? Does your dishwasher simply fail to start up? If so, you\u2019re not alone. These three complaints make up the vast majority of dishwasher problems. But now the good news: You can solve these dishwasher repair problems about 90 percent of the time without calling for a dishwasher repair technician.<\/em> Instead of paying $70 for a service call, do the work yourself in less than 30 minutes. Most dishwasher repairs involve only routine maintenance and require no special tools or skills and little or no expense. Read on to learn how does a dishwasher work.<\/p>\n

    In this article, we\u2019ll tell you how to pinpoint the causes of most dishwasher problems, then walk you through simple dishwasher maintenance steps to correct them, all with little to no dishwasher repair costs. In most cases, even a time-pressed novice can get the dishwasher working again within a half-hour.<\/p>\n

    We\u2019re using a GE dishwasher for our demonstration, but most brands and models have a similar design. Pull out the owner\u2019s manual and compare it with our illustrations to help identify and locate key parts. It will also help you identify part numbers when you need them. If you can\u2019t find the manual, you can usually find one on the appliance manufacturer\u2019s site. Sometimes appliance dealers can also provide manuals.<\/p>\n

    How a Dishwasher Works<\/h3>\n

    A dishwasher doesn\u2019t fill like a clothes washer. Instead, 2 to 3 gallons of water flood the lower portion of the tub, where it mixes with the detergent and is pumped through the rotating spray arms onto the dishes. The wash water drains and is replaced by fresh water to rinse the dishes.<\/p>\n

    The cycle often repeats several times. A timer regulates the water volume. A heating element near the bottom raises the dishwasher water temperature to 140 to 160 degrees F. The element also helps dry the dishes after the wash and rinse cycles are completed.<\/p>\n

    Problem 1:<\/strong> Your dishes don\u2019t come out clean<\/h2>\n

    A. Review the basics for how a dishwasher works (5 minutes)<\/strong><\/p>\n

      \n
    • Are you overloading your dishwasher? Check the manufacturer\u2019s instructions to make sure you\u2019re loading it right.<\/li>\n
    • Does silverware drop below the lower basket? The spray arm can\u2019t spin if obstructed.<\/li>\n
    • Are you using the proper dishwasher detergent?<\/li>\n
    • Do you routinely scrape food bits off dishes before loading them into the racks? (Rinsing is not necessary.)<\/li>\n
    • Are you using a special rinsing agent if your water is hard (highly mineralized)? Hard water can leave a film on the dishes.<\/li>\n<\/ul>\n

      Tip:<\/strong> Adding a water softening system can dramatically improve dishwasher performance.<\/p>\n

        \n
      • Is the water temperature high enough? This can be a complex issue.<\/li>\n<\/ul>\n

        We recommend that your household water heater be set no higher than 120 degrees F, both to help prevent accidental scalding and to maintain energy efficiency. Many dishwashers have heating elements that boost the temperature to about 140 degrees. However, some dishwashers don\u2019t have a heating booster and require household water at about 140 degrees. So first check the owner\u2019s manual for the recommended water heater setting.<\/p>\n

        If your dishwasher requires<\/em>140-degree water, check the temperature of your hot water at its current setting. Put a meat thermometer in a glass and fill it at the kitchen faucet with water at its hottest point. If the temperature reads less than 140 degrees, you\u2019ll have to either risk raising the water heater setting (we don\u2019t recommend it) or consider buying a different dishwasher. But check the dishwasher maintenance steps below first to make sure poor cleaning isn\u2019t caused by other factors. In any case, consult a service pro before making a buying decision.<\/p>\n

        B. Clean the dishwasher spray arm (10 minutes)<\/strong>
        Twirl the spray arm to make sure it spins freely. Also check the holes in the spray arm for debris. If you spot debris or the spray arm doesn\u2019t spin, remove the spray arm and clean it (Photos 1 \u2013 3).<\/p>\n

        First take out the wire baskets by removing either a cap or pin at the end of the sliding tracks. Don\u2019t fret about a little water on the bottom of the tub. It\u2019s supposed to be there. It keeps the seals in the pump and in the motor assembly damp. If they dry out, they\u2019ll crack and leak.<\/p>\n

        The spray arm cap twists off with a clockwise turn, just the opposite of a regular screw (Photo 1). Twist ties, rubber bands and plastic and paper often show up in the spray arm. You might have to use a needle-nose pliers to pick them out. The pump usually sucks up most of this stuff, but if you hear a sudden loud grinding sound while running the dishwasher, something like broken glass might be stuck in the pump intake. Unscrew and remove the pump cover (Photo 2) to check it out.<\/p>\n

        C. Clean the dishwasher float switch (5 minutes)<\/strong>
        The float switch may not be a problem, but it takes only a few minutes to check it, so open it up and clean it anyway (Photos 4 and 5). Debris can cause the float to stick in the raised position, which prevents the tub from filling. If the water doesn\u2019t reach the right level (just covering the heating element), the dishwasher won\u2019t clean well. See the next section for how to check the water level.<\/p>\n

        On most models, you\u2019ll find the float switch in the lower front of the tub (Fig. A and Photo 4). Ours has a cover, but some don\u2019t. You may have to use a small, flexible brush or pipe cleaner to clean those without a removable cover. When clean, the float should slide up and down freely.<\/p>\n

        D. Clean the dishwasher valve screen (30 minutes)<\/strong>
        One common symptom of a clogged intake valve screen is a low water level during the dishwashing cycle. (Low water could also indicate a clogged float switch, but you\u2019ve already taken a few minutes to check it.) So before going through the somewhat more complex steps for cleaning the intake valve screen, check the water level.<\/p>\n

        Close the door, turn on the machine and run it until it\u2019s done filling during its second cycle. Then open the door (the machine will automatically shut off), and check the water level. If the water doesn\u2019t come up to the heating element, it\u2019s too low. Close the door and let the machine cycle on through. Then proceed to clean the intake valve screen (Photos 6 \u2013 9).<\/p>\n

        You\u2019ll have to unhook several wires, so always begin by turning off the electrical power to the dishwasher at your main panel. Turn off the water supply to the dishwasher as well. Usually the shutoff is at the hot water supply line under a nearby sink. The inlet valve is usually mounted on the underside of the dishwasher near the front.<\/p>\n

        You have to remove the lower panels (Photo 6) and disconnect the valve (Photos 7 and 8) to get at the valve screen, a wire screen mounted within the body of the valve itself (Photo 9). If the wires don\u2019t pull off readily, push the small spot in the center of the connector to release them. And mark one wire and its terminal with tape so you can get them back on the same way. (In this case it doesn\u2019t matter, but it\u2019s a good practice anyway.)<\/p>\n

        Tip:<\/strong> Keep a rag handy. You\u2019ll have to mop up a bit of water when you unhook the copper supply tube.<\/p>\n

        Some pros prefer to simply replace the valve on old machines to avoid problems in the near future. Search for \u201cAppliance Parts\u201d to find the right valve for your dishwasher.<\/p>\n

        Tip:<\/strong> Stick the end of the supply tube into a pan and turn on the water supply briefly to flush out sediment before reconnecting the supply tube.<\/p>\n

        Now run a load of dishes. If the dishes still don\u2019t come clean, call in a service expert to find the problem.<\/p>\n
