What To Know
- As the dishwasher fills and empties, dishes can knock against each other or the racks, creating a banging or scraping noise.
- A persistent grinding or humming noise can be a sign of a worn-out motor or a faulty drain pump.
- Understanding the sources of dishwasher noise and implementing the solutions outlined in this guide can significantly reduce the noise levels in your household.
Does your dishwasher create a symphony of clanging and thumping that disrupts your household harmony? If so, you’re not alone. Many dishwashers produce a range of noises during their operation, but understanding the sources of these sounds can help you mitigate them effectively.
Why Do Dishwashers Make Noise?
Dishwashers generate noise due to several factors:
1. Water Flow
The gushing water during the wash and rinse cycles can create a loud hum or roar. This noise is amplified by the enclosed nature of the dishwasher.
2. Spray Arms
Rotating spray arms distribute water over the dishes, but their movement and impact on the dishes can produce a clattering or thumping sound.
3. Dishware Movement
As the dishwasher fills and empties, dishes can knock against each other or the racks, creating a banging or scraping noise.
4. Drain Pump
The drain pump removes wastewater from the dishwasher, but it can generate a humming or buzzing sound as it operates.
5. Motor
The motor powers the dishwasher’s various components, and its vibrations can translate into a low-frequency rumble or humming.
How to Reduce Dishwasher Noise
1. Use a Quiet Dishwasher
Look for dishwashers with a noise rating of 45 decibels or less. This indicates a relatively quiet operation.
2. Load Dishes Properly
Avoid overloading the dishwasher or placing dishes too close together. This reduces dishware movement and minimizes noise.
3. Use Soft Water
Hard water can create mineral deposits on the dishwasher’s components, leading to increased noise. Using soft water can help prevent this.
4. Clean the Drain Filter
A clogged drain filter can restrict water flow and increase noise levels. Clean the filter regularly to ensure proper drainage.
5. Level the Dishwasher
An unlevel dishwasher can cause vibrations that amplify noise. Use a level to ensure the dishwasher is installed correctly.
6. Add Sound Dampening Materials
Place rubber mats or sound dampening pads inside the dishwasher to absorb vibrations and reduce noise.
7. Insulate the Dishwasher
If possible, consider insulating the dishwasher by placing soundproofing material around it or building a soundproof enclosure.
When to Call a Technician
While most dishwasher noises are normal, some may indicate underlying issues:
1. Excessive Clanging
Loud banging noises during the wash cycle could indicate a loose spray arm or a broken dish rack.
2. Grinding or Humming
A persistent grinding or humming noise can be a sign of a worn-out motor or a faulty drain pump.
3. Rattling or Buzzing
Rattling or buzzing noises may indicate loose components or a malfunctioning timer.
