When this trusty kitchen appliance is running properly, you can expect to hear certain sounds and noises, such as humming, swishing or hissing. But when does a noisy dishwasher signal a real problem? Here’s what you need to know about loud wash cycles and when it’s time to call a professional to inspect the problem.
Excess Food or Debris
Do you hear a grinding noise when your dishwasher runs? Sometimes a noisy dishwasher is easy to address, especially if the problem is a simple one. If your dishes have excess food or debris on them, it can clog up the appliance’s components. For example, seeds, popcorn or leftover bones can get trapped in the machinery, and simply removing the debris might quickly solve the issue.
Dish Racks and Rails
It isn’t uncommon for the dish racks to be pulled off the rails due to daily and frequent use. First, look at the racks and runners to make sure the racks are securely in place in the runners. If not, putting the dish racks back in the runners is a quick fix. Also, if the fasteners holding these parts together are loose, clanging sounds can result when the appliance is running through its cycles. Once tightened, the noise should stop. If not, it might be a good time to call a professional to troubleshoot the issue.
If your appliance leans forward when you open the door, it might need to be anchored to the cabinet or the counter. Dishwashers can become detached from the counter over time, or they may not have been anchored to the counter when your house was built. A thumping sound or other loud noise may be a sign that your dishwasher needs to be fastened to the cabinet, a job that is best performed by a professional.
New dishwashers often make a squealing noise for the first few wash cycles. Usually, after running two or more cycles, the noise will stop. If your appliance is older, or if your noisy dishwasher persists, the motor may require repair or replacement. Dishwasher motors don’t last forever and when they wear out, they can cause a rattling sound when the appliance is operating. The pump, which is located close to the motor, may also be clogged. Food, bone shards or other debris may be clogging the pump, which can cause noisy dishwashers. It’s wise to call in a pro if you suspect mechanical issues are causing noisy wash cycles.
Are banging noises common when your appliance runs? It might be water hammer, which happens when a valve suddenly shuts down water flow. The banging noise occurs because turning off the flow sends pressure through the water line and shocks the pipes, creating a hammering noise. Although you might be tempted to investigate the problem, it’s best to reach out to a plumber who can troubleshoot the issue and make necessary repairs.
