Quick answer

Ensure water valves are fully open and the inlet filter is clean. Check for kinks in the hoses and verify the water pressure is adequate. If the issue persists, inspect the water inlet valve for faults.

Tools and prep

Step-by-step troubleshooting

  1. Check Water Supply Valves
    Do: Locate the water supply valves under the washer and ensure they are fully open.
    Observe: Valves are open and not partially closed.
    Means: Valves are properly positioned.
    Next: If valves are open, proceed to step 2.
  2. Inspect Inlet Filter
    Do: Turn off the water supply. Remove the inlet filter from the cold water valve using a wrench. Clean any debris or sediment.
    Observe: Filter is clean and free of clogs.
    Means: Clogged filter was restricting water flow.
    Next: If filter is clean, proceed to step 3.
  3. Check Water Hoses
    Do: Inspect the inlet hoses for kinks, cracks, or blockages. Straighten any kinks and replace damaged hoses.
    Observe: Hoses are straight and undamaged.
    Means: Kinked or damaged hoses were limiting water flow.
    Next: If hoses are clear, proceed to step 4.
  4. Verify Water Pressure
    Do: Use a water pressure gauge to check the water pressure at the inlet. Normal pressure should be between 20–100 psi.
    Observe: Water pressure is within the normal range.
    Means: Low water pressure is preventing proper filling.
    Next: If pressure is low, proceed to step 5.
  5. Test Water Inlet Valve
    Do: Unplug the washer. Remove the front panel to access the water inlet valve. Use a multimeter to test for continuity. If there is no continuity, the valve is faulty.
    Observe: Multimeter shows continuity or no continuity.
    Means: Faulty water inlet valve is not allowing water to flow.
    Next: If the valve is faulty, replace it.
  6. Check for Water Supply Issues
    Do: Check if other fixtures in the house have low water pressure. This could indicate a problem with the main water supply or a partially closed main valve.
    Observe: Other fixtures have normal water pressure.
    Means: Housewide water supply issue is affecting the washer.
    Next: If housewide issue, contact a plumber.

FAQ

Can a clogged inlet filter cause the washer not to fill?

Yes, a clogged inlet filter can restrict water flow, leading to the washer not filling completely. Cleaning or replacing the filter often resolves the issue.

How do I check the water pressure for my washer?

Use a water pressure gauge attached to a faucet near the washer. Normal pressure should be between 20–100 psi. If it's lower, check the main water supply or install a pressure regulator.

What if the water inlet valve is faulty?

A faulty water inlet valve will need to be replaced. Turn off the power and water supply before replacing it to ensure safety.

Why is the water pressure low in my house?

Low water pressure can be due to a partially closed main valve, a problem with the municipal water supply, or a clogged pipe. Check other fixtures to determine if it's a housewide issue.
