Understanding the Problem
Brief explanation: The inlet valve controls incoming water to the washer. It opens and closes via electrically driven solenoids when the machine needs hot or cold water. On model WCXR1070T5WW a failing inlet valve will cause no water fill, slow fill, continuous filling, leaks at the rear, or a washer that only fills with one temperature. Step-by-step diagnostic and repair steps: 1) Verify the symptom and simple causes: a) Confirm water supply is on at both hot and cold shutoff valves behind the machine. b) Check inlet hoses for kinks, collapse, or clogged screens at the hose ends. c) If the washer has power but does not fill, proceed to valve checks. 2) Inspect the inlet screens and hoses: a) Turn off water supply and unplug the washer. b) Unscrew the fill hoses from the back of the washer and inspect the small mesh screens in the valve ports. Remove debris and mineral buildup with a soft brush. c) Reattach hoses and test. If problem persists, continue. 3) Electrical checks on the inlet valve: a) Unplug the washer and remove the access panel (back or front panel per model). b) Identify the inlet valve assembly and note the wiring harness locations or take a photo for reassembly. c) Use a multimeter set to ohms. Test resistance across each solenoid. Typical solenoid resistance ranges 500 to 1500 ohms but consult the service sheet for exact values. Infinite or zero resistance indicates a failed coil. d) With the washer plugged in and set to a fill cycle, use a voltmeter or test light to confirm the control board is sending voltage to the valve during the fill step (exercise caution—live testing is hazardous). If the board sends voltage but the valve does not open, valve is bad. If the board does not send voltage, problem is control or pressure switch. 4) Mechanical checks: a) Look for visible leaks at the valve body or cracked plastic. Replace if leaking. b) Check for stuck valve plunger by attempting to depress it manually after removing the valve; heavy mineral deposits can jam the plunger. 5) Replace the inlet valve if tests indicate electrical failure, physical leak, or irreparable screen blockage. Replacement steps: a) Turn off power and both water supplies. b) Disconnect the water hoses and remove the washer access panel to reach the valve assembly. c) Label or photograph harness connections, then unplug electrical connectors and remove mounting screws holding the valve. d) Remove the old valve, transfer any rubber gaskets or mounting pieces if required, and install the new valve in reverse order. Ensure inlet hose washers and screens are present and undamaged. e) Reconnect hoses, turn on the water and power, and run a test cycle to confirm proper filling and no leaks. 6) If the washer fills constantly or floods after valve replacement, check the pressure switch/water level sensor and associated air tube for blockage or leaks; these can cause the control to continuously energize the valve. Safety note: Always disconnect electrical power and shut off water before working on the appliance. When testing live circuits use proper insulated tools and take precautions or hire a technician if you are not comfortable working with mains voltage.
Common Symptoms
No fill, very slow fill, fills only cold or only hot, continuous filling, water leaking at the back of the washer, or error codes related to water fill.
Common Causes
- Failed solenoid coil in the inlet valve
- Clogged or damaged inlet screens or hoses (mineral deposits/debris)
- Cracked valve body or leaking gasket
- Control board or water level sensor not signaling the valve

Helpful Repair Tip
If one solenoid reads normal resistance and the other is open or shorted on a multimeter, the valve assembly must be replaced. Cleaning screens only helps when flow is restricted but will not fix an electrical coil failure.
Frequently Asked Questions
How do I know if the inlet valve or the control board is bad?
Test approach: with the washer plugged in and set to a fill cycle, measure voltage at the inlet valve connector when the machine should be filling. If voltage (typically 120V AC on many washers) is present and the valve does not open, the valve is at fault. If no voltage is present, the control board, timer, or a safety/pressure switch may be at fault. If unsure or uncomfortable doing live voltage checks, replace the valve only after checking coil continuity; if coils are good but no voltage is present, investigate control and sensors.
Can I clean the inlet valve instead of replacing it?
Cleaning the mesh screens and removing mineral deposits can restore flow if the symptom is slow or restricted fill. However, cleaning will not fix an electrically failed solenoid, cracked body, or an internal plunger that no longer seals. If the solenoid has open/shorted windings or the valve leaks, full replacement of the inlet valve assembly is recommended.
