Quick answer

A washer making noise during fill is often due to a water supply issue or a faulty inlet valve. Turn off the water, check for sediment or kinks, and inspect the inlet valve for damage. Replace if necessary.

Confirm the symptom

Noise happens only during the fill cycle
Sound is a loud whining or hammering
Water pressure seems low or fluctuating

Tools and prep

Screwdriver set
Adjustable wrench
Plumber's tape
Flashlight
Bucket or towels
Turn off power at the circuit breaker
Shut off water supply valves

Step-by-step troubleshooting

Check Water Supply Valves
Do: Ensure both hot and cold water valves are fully open.
Observe: Valves are open but noise persists.
Means: Valves are not the issue.
Next: Check for kinks or blockages in the hoses.
Inspect Hoses for Kinks
Do: Look for kinks or bends in the inlet hoses.
Observe: Kinks are found and removed.
Means: Kinks may have restricted water flow.
Next: Test the washer again.
Check for Sediment Buildup
Do: Turn off water supply and disconnect hoses. Inspect for sediment.
Observe: Sediment or debris is present in the hoses or valves.
Means: Sediment is causing the noise.
Next: Clean the hoses and valves or replace them.
Test Water Pressure
Do: Use a water pressure gauge to check the home's water pressure.
Observe: Pressure is below 20 psi or fluctuates.
Means: Low or unstable pressure is causing the noise.
Next: Install a pressure regulator if needed.
Inspect Inlet Valve
Do: Check the inlet valve for damage or mineral buildup.
Observe: Valve shows signs of wear or clogging.
Means: Faulty inlet valve is likely the cause.
Next: Replace the inlet valve.
Replace Inlet Valve
Do: Turn off power and water. Disconnect old valve and install a new one.
Observe: Noise stops after replacement.
Means: Inlet valve was the issue.
Next: Reconnect water and power, then test the washer.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Clogged Inlet Valve Mineral deposits or debris block water flow, causing noise.	Common	Medium	Inlet Valve
Kinked or Clogged Hoses Restricted water flow leads to unusual noises during fill.	Common	Easy	Water Hoses
Low Water Pressure Insufficient pressure causes the valve to work harder, creating noise.	Sometimes	Easy–Medium	Pressure Regulator
Faulty Water Supply Valve Partially closed or damaged valve restricts water flow.	Sometimes	Easy	Water Supply Valve
Air in the System Trapped air causes hammering or gurgling sounds.	Rare	Easy	Air Bleed Valve
Worn Inlet Valve Diaphragm A damaged diaphragm can cause erratic water flow and noise.	Sometimes	Medium	Inlet Valve

When to call a professional

Noise persists after replacing the inlet valve and hoses
Water pressure issues affect the entire home
You're unsure about electrical or plumbing repairs
Leakage occurs after attempting repairs

FAQ

Can low water pressure damage my washer?

Low pressure can strain the inlet valve and reduce washer efficiency but typically doesn't cause direct damage.

How often should I replace water supply hoses?

Replace every 5 years or if you notice cracks, kinks, or leaks.

Is it safe to use a pressure regulator for my washer?

Yes, a pressure regulator can stabilize water flow and prevent noise caused by fluctuating pressure.

What if the noise only happens on one cycle?

It could indicate a partially clogged valve or hose. Inspect and clean both hot and cold water lines.
