People prize the quiet hum of a modern dishwasher. Sometimes we can’t even tell they’re running, to the point that many dishwashers have a little light so we know they’re on. When we shop for a dishwasher, one of the first things we look at is the noise rating.Old dishwashers could be very loud (and incredibly inefficient), but they had one big, noisy advantage. They often included a food chopper that pulverized your leftover crumbs into tiny bits that washed down the drain. Most modern dishwashers collect those bits of food in a filter instead, and that means you need to empty and clean the dishwasher filter regularly.Pros And Cons Of A Food ChopperAlso called a hard food disposer, a food chopper is located in the bottom of a dishwasher tub. The blades grind up food intermittently during the wash cycle and can make a noticeable grinding noise or hum. Some manufacturers still sell dishwashers with a disposer, but most use a filter now instead to lower the noise level.Despite the noise, food choppers have some advantages. They prevent bits of food from repeatedly recirculating in the wash. You don’t have to clean a food chopper or worry about it clogging.Pros And Cons Of A FilterDishwashers without a disposer can be extremely quiet. The noise produced by some of the higher-end models is nearly undetectable to our ears. On the other hand, filters can get clogged, which affects the performance of your dishwasher. The clog can interfere with draining and cause odors. You should clean your dishwasher filter at least once a month to prevent this from happening.Other Reasons Dishwashers Are NoisyWhile the food chopper on an old dishwasher can be noisy, there could be a problem that needs your attention. Consider whether one of these situations could be occurring:Thumping: The spray arm could be hitting something tall, like a cutting board or oversized plate. Make sure the arms are free and clear of any obstructions when you load the dishwasher.Loud grinding: Something could be caught in the disposer blades or drain impeller. You’ll need to open up the dishwasher to examine the food chopper or call a technician.Loud hums, squeaks, and rattles: While many old dishwashers do emit a loud hum, sometimes this can be caused by a problem with a pump. And if your dishwasher rattles even on an empty load, this does indicate mechanical problems.Read the original article on Southern Living
