Dishwashers are a modern marvel, making our lives easier by effortlessly cleaning our dishes. However, sometimes we may encounter an annoying humming sound coming from the appliance. This can be frustrating and concerning, leaving us wondering “why dishwasher makes humming sound?” In this comprehensive guide, we will explore the various reasons behind this humming noise and provide practical solutions to resolve the issue.
1. Faulty Water Inlet Valve
The water inlet valve is responsible for regulating the flow of water into the dishwasher. A faulty valve can cause water hammer, which results in a loud humming sound. This can occur due to debris or mineral buildup inside the valve, preventing it from opening and closing smoothly.
2. Loose or Damaged Hoses
Loose or damaged hoses can also contribute to humming noises. When the hoses are not properly secured, they can vibrate against the dishwasher or other objects, creating an annoying sound. Additionally, damaged hoses can leak water, which can cause further humming or rattling noises.
3. Clogged Filter
The dishwasher filter is designed to trap food particles and debris to prevent them from entering the drain. When the filter becomes clogged, it can restrict water flow, causing the dishwasher to work harder and produce a humming sound. Regular cleaning of the filter is essential to maintain optimal performance.
4. Worn-Out Motor
The motor is the heart of the dishwasher, responsible for powering the spray arms and draining the water. A worn-out motor can lose its efficiency, causing it to work harder and louder. This can result in a humming sound that becomes more pronounced over time.
5. Misaligned Spray Arms
Spray arms distribute water throughout the dishwasher to clean the dishes. If the spray arms are misaligned or damaged, they can hit against the dishes or the walls of the dishwasher, creating a humming noise. Proper alignment and inspection of the spray arms are important to prevent this issue.
6. Resonance from Dishes
In some cases, the humming sound may be caused by resonance from the dishes inside the dishwasher. When the dishes are not properly loaded or are too close to each other, they can vibrate and create a humming sound. Rearranging the dishes and ensuring they have sufficient space can resolve this issue.
7. Electrical Issues
Electrical issues, such as loose wiring or a faulty electrical component, can also lead to humming noises. These issues can be dangerous and should be addressed by a qualified electrician to prevent further damage or electrical hazards.
Resolving the Humming Sound
Identifying the source of the humming sound is crucial for effective troubleshooting. Once the cause has been determined, the following steps can be taken to resolve the issue:
- Replace the water inlet valve: If the water inlet valve is faulty, it should be replaced with a new one.
- Tighten or replace hoses: Loose or damaged hoses should be tightened or replaced to eliminate vibrations and leaks.
- Clean the filter: Regularly cleaning the dishwasher filter will prevent clogging and ensure smooth water flow.
- Repair or replace the motor: If the motor is worn out, it may need to be repaired or replaced by a professional appliance technician.
- Align the spray arms: Misaligned spray arms should be adjusted or replaced to prevent them from hitting the dishes or walls.
- Rearrange the dishes: Ensure that the dishes are properly loaded and have sufficient space to prevent resonance.
- Contact a qualified electrician: For electrical issues, consult a qualified electrician to diagnose and resolve the problem safely.

By understanding the various reasons why a dishwasher makes a humming sound and implementing the appropriate solutions, you can restore your dishwasher to its quiet and efficient operation. Regular maintenance, such as cleaning the filter and inspecting the hoses, can help prevent future humming issues. If the humming sound persists or is accompanied by other symptoms, do not hesitate to contact a qualified appliance technician for further assistance.
