218859701 Frigidaire Single Solenoid Water Valve is an electrically actuated inlet valve assembly designed to control the flow of potable water into household appliances.As a single‑solenoid device, it uses one electromagnetic coil to move an internal plunger or diaphragm from a normally closed position to an open position when energized; the valve body typically includes an inlet and one or more outlet ports, a sealing seat or diaphragm, and a built‑in strainer or screen to trap debris.
Inside an appliance the valve functions as the controlled gateway between the external water supply and internal water circuits. In refrigerators it is commonly used to feed ice makers and dispenser lines; similar single‑solenoid valves are used in dishwashers and washing machines to permit fill operations. The valve is driven by the appliance control board or a dedicated module and thus interfaces electrically with the control system while hydraulically connecting to the supply line,internal tubing,and any downstream sensors or flow devices. Proper operation prevents overfill and flooding, meters water delivery for cycles or dispensing, and isolates the supply when the appliance is idle.
In this article readers will find a detailed look at the valve’s function and internal components, guidance on verifying compatibility by model number, inlet/outlet size and connector type, common failure symptoms to watch for (electrical coil failure, stuck or leaking seats, clogged strainers), and a systematic approach to troubleshooting (visual inspection, electrical continuity checks, pressure and flow verification). The article will also cover practical replacement considerations such as shut‑off and purge procedures, part selection, and installation checkpoints to ensure reliable operation after service.

Function and Role of the Solenoid Water Valve in Frigidaire Dishwashers
The 218859701 frigidaire Single solenoid Water Valve is the appliance-level inlet valve that permits mains water into the dishwasher under electronic control. As a single‑solenoid, electrically actuated device it remains normally closed and opens when the dishwasher’s control board energizes the coil, allowing water to pass through the internal diaphragm or plunger assembly. Physically the part is intended to mount in the same location and use the same inlet fittings as the factory valve on compatible Frigidaire units, so replacement is generally a mechanical and electrical swap rather than a system redesign; confirm model compatibility and inlet pressure range against the service documentation before installation.
During a wash cycle the control board times the valve’s open interval (and in some models modulates it) to achieve the required fill volume; improper valve behavior will therefore produce clear, repeatable symptoms. Common operational issues include no-fill (valve fails to open), continuous-fill or slow leak (valve fails to fully close), and intermittent filling caused by coil or connector faults. Troubleshooting typically uses a multimeter to verify coil continuity and resistance,inspection of the valve seat for debris,verification of inlet water pressure,and checking that the control board is providing the expected actuation voltage per the service manual. Practical examples: a stuck-open valve frequently results in an overflow condition and a tripped float switch, while an open-coil fault produces a no-water condition despite the control calling for fill.
- No-fill: open-coil or failed electrical connection
- continuous-fill: leaking seat, debris, or mechanical failure
- Intermittent fill: loose connector, solder joint, or control signal issue

How the 218859701 Frigidaire Single Solenoid Water Valve Works Inside the Appliance
The 218859701 Frigidaire Single Solenoid Water Valve is a direct-acting inlet valve that uses one electromagnetic coil to move a plunger or poppet against an elastomer seat, controlling water flow into the appliance. When the appliance control supplies voltage to the coil, the plunger lifts against a spring, opening the port and allowing water to pass; when the coil is de-energized the spring returns the plunger to the seat and stops flow. Inside the valve assembly the seat geometry, port size and inlet screen determine flow characteristics and susceptibility to particulates, so matching the OEM part ensures the correct flow rate and sealing surfaces for a given Frigidaire model and plumbing pressure range.
- Operation: normally closed valve that opens only while the coil is energized.
- Common failure modes: coil burnout, stuck plunger (debris or corrosion), worn seat causing leakage, or cracked body causing external leaks.
- Service checks: measure coil resistance with an ohmmeter, verify control voltage at the connector during a fill cycle, and inspect the inlet screen for debris.
| Item | Description |
|---|---|
| Valve type | Single-solenoid, direct-acting poppet (spring-return) |
| Electrical | Appliance control supplies coil voltage; verify value from service manual (common designs use line or low-voltage AC depending on model) |
| Plumbing | OEM-matched inlet/outlet sizes and fittings; internal screen and porting determine flow rate under nominal pressure |
Functionally, the valve interfaces between the plumbing and the appliance control: the control issues a timed command, the valve provides a predictable open window for filling, and downstream sensors or mechanical floats determine when to stop. In practical service situations this means intermittent no-fill symptoms usually indicate an electrical or coil issue, whereas slow fills or continuous drip frequently enough point to debris, a damaged seat, or incorrect pressure/flow characteristics from an incompatible replacement. Technicians should confirm mechanical mounting, connector type, and pressure rating when replacing the part, and bench-test the coil and plunger movement (with appropriate safety precautions) before installation to avoid misdiagnosis or secondary leaks.
Common Failure Symptoms and Diagnostic Indicators of the Solenoid Water Valve
The 218859701 Frigidaire single Solenoid Water valve is a normally-closed electromechanical valve that controls water delivery to the ice maker and dispenser by opening a plunger/diaphragm assembly when its coil is energized. In practical installations the valve must match the appliance’s rated actuation voltage and inlet/outlet fittings; incorrect voltage, damaged solenoid windings, or mismatched ports will prevent proper operation. Mechanically, failures typically arise from a damaged diaphragm, debris trapped in the inlet screen, or a plunger that has seized; electrically, the common causes are an open coil, short to ground, or intermittent connections at the connector. Understanding whether a symptom is electrical (no coil drive) or hydraulic (restricted flow or a stuck plunger) directs the appropriate diagnostic steps and ensures correct compatibility when replacing the part on Frigidaire models that accept this assembly.
Typical failure indicators and diagnostic checks are straightforward for a technician: listen for a definite click when the ice-maker or dispenser is commanded and verify that the valve receives the expected control voltage; if voltage is present but no flow occurs, inspect the inlet screen and the valve’s internal plunger for mechanical blockage or seal failure. Use a multimeter to confirm continuity of the coil (infinite resistance indicates an open winding; very low resistance or a reading to chassis suggests a short), and verify flow rate under nominal house pressure to distinguish a weak valve from low water pressure. Examples: a refrigerator that clicks repeatedly but never fills often has a stuck plunger or clogged inlet screen,while a continuous fill indicates a leaking seat or debris preventing closure.
- No water fill despite audible click - suggests blocked inlet or stuck plunger with coil energized.
- Slow fill – could be partial blockage in inlet screen, reduced house pressure, or degraded valve orifices.
- Continuous fill or leaking - indicates seat/diaphragm failure or foreign object preventing closure.
- Clicking without valve actuation electrical presence - check coil continuity and applied voltage.
- Intermittent operation - check connector wiring, voltage during call, and coil resistance for thermal/incipient faults.
| Item | Description |
|---|---|
| electrical test | Measure control voltage at the valve during a fill cycle and check coil continuity with a multimeter; open circuit indicates coil failure, while presence of correct voltage with no flow implicates mechanical blockage. |
| Mechanical response | Inspect inlet screen and plunger for debris or corrosion; manually actuate (apply rated voltage briefly) to observe movement and flow response. |
| Flow verification | measure fill time or flow volume under normal house pressure to separate valve restriction from supply-pressure issues. |
| compatibility/fit | confirm the 218859701 frigidaire Single Solenoid water Valve matches the appliance’s inlet fittings, mounting points, and control voltage before replacement. |
Compatibility, Replacement Considerations, Installation Steps, and Troubleshooting Procedures
The 218859701 Frigidaire Single Solenoid Water Valve is a normally-closed electromechanical valve that controls water admission to a laundry or refrigeration appliance by translating a coil-driven axial plunger movement into an open flow path. Compatibility depends on a handful of measurable details: inlet/outlet thread or barb sizes, mounting footprint, electrical connector and coil voltage, and the valve’s operating pressure range. When evaluating replacements, compare the physical dimensions, inlet filter/screen configuration and electrical ratings to the original valve; mismatches in voltage or port sizing are the most common causes of operational failure or leaks after replacement. OEM and aftermarket parts can be interchangeable if these specifications match exactly, but transferring gaskets and verifying the seat and diaphragm condition before installation reduces the likelihood of post-repair leaks or intermittent operation.
Install and verify the valve using controlled, methodical steps and basic electrical checks to avoid damage or improper operation. Typical installation and troubleshooting procedures include isolating power and water, confirming coil continuity and correct supply voltage with a multimeter, inspecting and cleaning inlet screens, and performing a pressured leak and functional cycle test after reassembly. If the valve does not actuate electrically while the control board provides voltage, check for clogged ports, stuck plungers, or failed control outputs; if the valve actuates but does not stop leaking, inspect the internal seat and seals for wear or debris.
- Shut off water and power; relieve system pressure before removal.
- Measure and match inlet/outlet size,mounting points,and coil voltage before replacement.
- Test coil resistance and supply voltage at the connector during a call-for-water.
- Clean inlet screen and transfer any OEM gaskets or retainers to the new valve.
- After installation, pressurize the system and run a water-fill cycle to check for leaks and correct timing.

Q&A
What is the 218859701 Frigidaire Single Solenoid Water valve and what does it do?
The 218859701 is a water inlet/solenoid valve used on Frigidaire refrigerators. It controls water flow from the household supply to the ice maker and/or water dispenser. When the refrigerator’s control signals the valve, the solenoid opens and allows water to pass; when de-energized the valve closes and stops flow.
Which refrigerator models will this valve fit?
This valve is listed for use on many Frigidaire and compatible brand refrigerators. Exact compatibility depends on the refrigerator model and year-always confirm compatibility by checking your refrigerator model number against the part number on the manufacturer’s compatibility chart or an authorized parts supplier before ordering.
What are common symptoms that the valve is failing?
Common signs include: no water or very low flow to the dispenser or ice maker, intermittent filling, continuous water flow or leaking from the valve, noisy or humming valve when it should be off, and ice maker overfilling.Some issues can also be caused by clogged filters or low household water pressure, so those should be checked first.
How can I test the valve to see if it’s defective?
First disconnect power and water. Visually inspect for leaks or blockages. Use a multimeter to check for electrical continuity across the solenoid terminals-there should be continuity (an open coil indicates a failed solenoid). You can also apply the appropriate rated voltage briefly (only if you’re qualified and safe to do so) to see if the valve actuates and allows water through. Exact coil resistance and voltage vary by model-refer to the service manual or the valve label.
How do I replace the 218859701 valve?
Turn off the refrigerator’s power and shut off the water supply. Move the fridge and remove the access panel to reach the valve. Disconnect the electrical connectors and the inlet/outlet water lines (have a towel/container ready). Remove mounting screws and swap in the new valve, reverse the steps to reattach lines and electrical connectors, restore water and power, and check carefully for leaks and correct operation.
Can the valve be repaired or should I replace it?
Most technicians recommend replacement rather than repair because internal diaphragms and seals often fail and are not serviceable.If the valve body is clogged with debris, a cleaning may help temporarily, but replacement is the reliable long-term fix. Use an OEM or quality replacement part to ensure correct fit and performance.
Is 218859701 an OEM Frigidaire part and where can I buy it?
