No water entering? Separate a fill delay, a supply restriction and a continuing fault before ordering an inlet valve. This guide covers safe observations, not internal tests or a universal reset.
First, identify what “not filling” means
Write down the full model, selected cycle and exact message. Look from a safe position: does no water enter, does filling start late, is just one temperature affected, or is water entering and disappearing? Those are different service observations.
Choose the state you can actually observe
The cycle has only just begun
Check the model manual for its normal starting or sensing stage. Samsung distinguishes a delay from no fill. Do not use another model’s calibration buttons or a guessed waiting period.
No water enters and the washer is otherwise powered
With the machine stopped, check accessible supply valves and visible hose bends without disconnecting anything. Match the supply layout to the installation instructions. Record an inaccessible connection as unchecked.
Water enters, but I expected more
Low visible water alone does not identify a failed valve. Check the applicable load and cycle guidance before changing anything. Do not add water manually or defeat a sensor to force a higher level.
Water enters and then leaves, or only one temperature is affected
Record which state occurs. Compare the drain setup or temperature/supply arrangement with the exact installation instructions. Keep this separate from an internal valve diagnosis.
One inlet or two? Use the documented configuration
Whirlpool’s general supply article describes hot and cold connections. Its compact front-load article describes a single-inlet arrangement. That is a configuration difference, not permission to add a connector or copy one layout to another washer.
Your next decision is whether the visible setup matches your own manual. If the number or labels of connections do not match the instructions, stop the installation check and obtain the correct document.
What the result tells you
An accessible supply condition was corrected
Resume only the normal operation permitted by the owner instructions. Record whether filling returned. A correction does not prove that an internal part failed.
The setup is correct but no water enters
Arrange model-specific diagnosis. Give the technician the exact code, cycle, observed water state and checks completed. Leave screen access, valve-coil tests and control tests to the applicable procedure and skill level.
Before buying a valve
A no-fill symptom is not a compatible-part number. Ask what finding supports the proposed repair, which full-model part match was used, and whether the complete quote includes labor and other confirmed faults.
Continue with the inlet-valve decision guide, installation checks or the full-model identification guide.
