Understanding the Problem
What the triple water inlet valve is and why it fails: The triple water inlet valve is the valve assembly at the back of the washer that controls the hot, cold and the third fill (prewash/softener or added water) ports. Each port is operated by a solenoid. When a solenoid fails or the internal valve seals or screens clog, the machine can under-fill, not fill with hot or cold, overfill, run continuously, or leak at the rear. 1) Confirm the symptom — note whether the washer is not filling at all, filling only with one temperature, filling slowly, overfilling/continuously filling, or leaking at the valve hose connections. 2) Visual check — unplug the washer and turn off both hot and cold water supplies. Pull the washer away from the wall and inspect the inlet valve and hoses for visible leaks, cracks, or corrosion. Remove hoses and check inlet screens on the valve for sediment or mineral buildup; clean if dirty. 3) Electrical test — with the washer unplugged, disconnect the valve wiring harness and use a multimeter to check each solenoid coil for continuity. Typical coil resistance for many washers is on the order of a few hundred to around a thousand ohms; a completely open coil indicates failure. 4) Functional test (low-risk) — after confirming electrical continuity, you can run a short fill cycle while watching the valve harness (be careful — live voltage present). If a coil has continuity but the valve doesn’t open, the solenoid may be mechanically stuck or the valve body leaking internally. 5) Check related components — if inlet valve tests ok, confirm the control sends a signal (use a multimeter or clamp-on voltmeter to measure voltage to the solenoid during a fill cycle) and verify the water level/pressure switch and control board are functioning. 6) Replace the valve if: a) solenoid coil is open or out-of-spec, b) internal valve leaks or is stuck, c) inlet screens are damaged or the valve body is cracked. How to replace the triple inlet valve (practical steps): 1) Buy the correct replacement valve for GTWN2800D0WW (see part section). 2) Unplug washer and shut off water to hot and cold supply lines. 3) Move washer away from wall and remove the inlet hoses. Drain any remaining water into a towel or bucket. 4) Remove the back panel or top panel as needed for access (usually a few screws). 5) Photograph or label each wiring connector on the inlet valve so reconnection is exact. 6) Remove the mounting screws securing the inlet valve and pull it away from the cabinet. 7) Disconnect the water inlet hose stubs from the valve (some valves use quick-connects or clamps). 8) Install the new valve in reverse order: attach hoses, secure mounting screws, reconnect wiring harnesses to the correct solenoids. 9) Reinstall panels, turn on water supply slowly and check for leaks at hose connections and valve body. 10) Plug in washer and run a test cycle (no clothes) to confirm proper hot/cold/third-fill operation and to confirm there are no leaks and that the control is actuating the valve properly. 11) If the washer still behaves incorrectly after replacing the valve, test the control board and pressure switch. Safety note: Always unplug the washer and shut off water before servicing. When testing live voltages use caution, proper insulated tools, and consider calling a professional if you are not comfortable working with mains voltage or pressurized water.
Common Symptoms
Washer won't fill; only cold or only hot water fills; very slow fill; washer continuously fills or overfills; water leaking at the hose connections or valve body.
Common Causes
- Failed solenoid coil (electrical open or internally shorted)
- Clogged or damaged inlet screens or sediment inside valve
- Worn internal seals or cracked valve body causing internal leakage or stuck valve

Helpful Repair Tip
To confirm the valve is at fault: remove inlet hoses, check and clean the screens, then measure coil resistance for each solenoid; an open coil or a solenoid that doesn’t energize during a fill cycle indicates the valve needs replacement.
Frequently Asked Questions
How much does it cost to replace the inlet valve?
Part cost for a GE triple inlet valve typically ranges from about $45 to $120 depending on OEM vs aftermarket. Labor if you hire a tech is usually 45–90 minutes, so count roughly $100–$200 additional depending on local rates.
Can I repair the inlet valve instead of replacing it?
You can often clean clogged inlet screens and remove debris, which fixes slow-fill symptoms. However, if a solenoid coil is open or the internal seals are leaking or stuck, the valve should be replaced — the assembly is inexpensive and more reliable than attempting a repair.
