Quiet operation is a hallmark of modern dishwashers but that doesn’t mean that any noise is cause for concern. Why is your Maytag dishwasher making noise when it fills with water? While hissing and flowing sounds are normal, rattling and vibrating could indicate a malfunction. When your dishwasher is loud, use these troubleshooting tips to decipher common sounds.
A Cry for Help or Business as Usual? Deciphering a Maytag Dishwasher Making Noise.
When troubleshooting dishwasher noise it’s important to distinguish normal sounds from those that point to a problem. Here’s how to determine if a Maytag dishwasher making noise is operating normally or in need of an intervention.
Maytag Dishwasher Making Humming Noise
Low humming sounds are generally considered a normal dishwasher noise. During a wash cycle, the drain pump may generate a low hum while operating. Similarly, some model dishwashers use fans at the end of a wash cycle to help dry dishes. These fans will also make a low humming sound that isn’t a cause for concern.
Dishwasher Making Noise When Filling
Is your dishwasher making noise when filling? Quiet sloshing, hissing, or flowing sounds are normal as water enters the dishwasher and begins to circulate. However, different sounds that are louder in volume or a dishwasher not cleaning dishes sufficiently could mean its water supply is compromised.
The following issues can cause loud noises when the dishwasher fills:
- Water supply valve is off: The dishwasher can make a loud banging sound if the valve that connects it to your home water supply is turned off. Locate the valve behind the dishwasher or under the kitchen sink and make sure it’s in the on position.
- Water inlet hose is kinked: Kinks in the water inlet hose can block water flow from your home supply. If the supply valve is on and you still hear your Maytag dishwasher making noise, check the hose for any bends or kinks. You may need to disconnect the hose to gently straighten any kinks.
- Faulty water inlet valve: This valve connects to the water inlet hose, opening and closing to regulate water flow from your home supply. If the valve malfunctions and is stuck closed, water won’t flow to the dishwasher. A faulty water inlet valve must be professionally replaced.
Grinding Noise Coming From Maytag Dishwasher
A Maytag dishwasher making noise when draining that sounds like grinding could indicate a drain pump obstruction. Hard food particles or debris that get caught in the pump’s impellers or the pump itself will make these sounds as water drains.
An experienced DIYer can refer to their user manual to access the pump and remove the obstruction. However, we suggest that a professional Maytag appliance repair service address this more complex job.
Noise Due to Faulty Part in Maytag Dishwasher
If the above tips don’t solve the mystery and you still hear your Maytag dishwasher making noise, a faulty part could be responsible.
The following part failures can result in a noisy dishwasher, requiring a professional repair:
- Drain pump: The drain pump expels used water from the dishwasher into the drain hose. If the pump isn’t obstructed and still makes loud sounds, it must be replaced.
- Circulation pump: In addition to the drain pump, dishwashers also have a circulation pump that forces water through the spray arms. If you find your dishwasher making noise when water circulates that sounds like a loud drone, the pump bearings may have failed. In this case, the circulation pump must be replaced.
- Drain or circulation pump impeller: Both the drain and circulation pumps use impellers to push water out of the dishwasher or through the spray arms. If the impellers are damaged or broken, they can make a scraping sound and must be replaced.
