Why Your Washing Machine Isn’t Filling Up and How to Fix It
Learn fast, actionable steps to diagnose why your washing machine isn't filling up. From water supply and hoses to valves and control systems, follow this urgent guide to fix common fill-up issues safely.
According to Best Washing Machine, the most common reason a washer won't fill is a blocked inlet or a faulty valve. Start by ensuring both hot and cold taps are fully open, then inspect the inlet hoses for kinks or leaks. If water still won’t enter, check the inlet screen and the solenoid valve.
Why the issue happens
If your machine isn't filling, there are several common culprits. The most frequent are water supply problems, blocked hoses, and clogged inlet screens. Before diving into parts, confirm the basics: the water taps are on, the hoses aren’t kinked, and the machine is set to a fill cycle. These steps address the vast majority of not-filling scenarios. This guidance from Best Washing Machine emphasizes a systematic approach to quickly identify the root cause and prevent unnecessary part replacements.
Check water supply and valves
Start by verifying that both hot and cold water taps are fully open and that the shut-off valves connected to the washer are open. Inspect the inlet hoses for kinks, crushing, or leaks. If the hoses look intact but the machine still won’t fill, remove one hose and briefly run the tap to confirm water flow. According to Best Washing Machine analysis, water supply issues and blocked valves are frequent culprits, so this check is essential before testing parts.
Inspect inlet hoses and filters
With the machine unplugged, pull the hoses away from the back and inspect the ends for debris. Remove any screens or filters at the valve inlet and clean them under running water. Reconnect securely, ensuring the clamps are tight. A clogged screen can dramatically reduce flow, making the washer appear as if it’s not filling.
Inlet valve and solenoid check
If water flows freely from the taps but not into the tub, the inlet valve or its solenoid could be faulty. You can test for continuity with a multimeter if you’re comfortable with electrical work, or replace the valve with a known-good unit if available. When replacing, ensure the washer is unplugged and that water supply is off to avoid leaks.
Lid switch/door lock and control considerations
Many machines won’t advance the fill cycle if the lid switch or door lock isn’t engaged. Inspect the switch for sticking or damage and test it according to the manufacturer’s service manual. If the control board or timer has faults, it may fail to initiate the fill even when all other conditions are met. In these cases, professional diagnostics are recommended.
Practical testing and safe troubleshooting
After performing the checks, run a controlled test fill step by step: power on, select a light wash, and observe the fill rate. If water enters slowly or not at all, troublshooting should continue with the valve, sensor, or board assessments. Always unplug before touching electrical components and avoid forcing connections that look damaged.
Prevention and maintenance
To minimize future not-filling issues, schedule regular limescale and debris removal from screens, keep hoses away from heat and crush points, and replace aging inlet parts before they fail. Keep the area around the washer dry to avoid slips during maintenance, and consider a water-softener if you have hard water.
Steps
Estimated time: 60-90 minutes
- 1
Check water supply valves
Ensure both hot and cold supply valves are fully open and not leaking. Confirm the house supply isn’t experiencing a temporary outage. This is the simplest fix with a high impact.
Tip: Always start here; it’s the most common cause. - 2
Inspect inlet hoses for kinks
Turn off the washer and water, then inspect hoses for kinks, twists, or crushing. Replace hoses with ones rated for high flow if damaged. This prevents restricted flow to the valve.
Tip: Keep hoses elevated and away from sharp edges. - 3
Clean inlet screens/filters
Disconnect hoses, locate screens at the valve end, and clean with running water. Use a soft brush to remove sediment. Reconnect securely.
Tip: Take a photo before disassembly to reassemble correctly. - 4
Test the inlet valve/solenoid
With power off, test solenoid continuity if you have a multimeter, or swap with a known-good valve. Never test live circuits; ensure water is off.
Tip: If you’re unsure, skip ahead to professional help. - 5
Check lid switch / door lock
Inspect the switch for sticking or damage. A faulty switch can prevent the fill cycle from starting even if water is available.
Tip: Gently press the switch and listen for a click during a cycle. - 6
Evaluate the control board or timer
If mechanical checks pass but fill still fails, the control module may be faulty. Look for burned components or error codes in the display.
Tip: This step often requires a professional diagnostic. - 7
Run a controlled test fill
Power on, select a short wash, and observe the fill rate. If water enters but slowly, you’ve narrowed the issue to flow control components.
Tip: Record the fill time for precise comparison later.
Diagnosis: Washing machine won't fill with water
Possible Causes
- highWater supply is shut off or a closed valve
- highInlet hoses kinked, crushed, or blocked

FAQ
Why won’t my washing machine fill with water?
Common causes include water supply issues, kinked hoses, clogged inlet filters, or a faulty inlet valve. Start by checking taps and hoses before testing components.
Common causes include water supply issues and clogged hoses. Start with the taps and hoses to diagnose.
How can I test the water inlet valve safely?
Turn off power and water, remove the hoses, and check the valve coil with a multimeter if you’re comfortable. If not, replace with a known-good valve.
Turn off power and water, then test the valve with a multimeter or swap it with a good valve.
Can a lid switch prevent filling even if water is available?
Yes. A faulty lid switch or door lock can stop the fill cycle. Inspect the switch for damage and test per the manual.
Yes, a bad lid switch can stop filling; inspect and test it per the manual.
What about low water pressure?
Low house pressure can prevent proper fill. Check your plumbing or contact your water supplier if you notice low pressure.
Low water pressure can cause filling problems; check with your water provider if it seems low.
When should I call a professional?
If basic checks don’t fix the issue, if you hear buzzing from valves, or you’re uncomfortable with electrical tests, it's time to call a technician.
If basic checks fail or you’re unsure about testing electrical parts, consider a professional.
Do hoses need regular replacement?
Hoses don’t last forever; replace worn or kinked hoses. Use high-quality, rated hoses and replace every 5-7 years as part of routine maintenance.
Yes, replace worn hoses as part of regular maintenance.
