Kenmore Washer F20: The "No Water" Error

Quick Fix Attempt (Resolves 70% of F20 Cases)

Your Kenmore washer posted F20 — it tried to fill with water and detected none arriving. Before you diagnose anything electronic, check these three things that cost nothing and take under five minutes:

1. Are both supply faucets fully open?

Walk behind your washer and check both hot and cold supply valves (the knobs or levers on the wall where the hoses connect). Someone may have turned one off for maintenance, a plumbing repair, or accidentally while moving items stored near the machine. Turn both fully counterclockwise (for knob-style) or parallel to pipe (for lever-style). Restart the cycle.

2. Are the inlet hose screens clogged?

Turn off both supply valves. Unscrew the hoses from the back of the washer (not from the wall side). Inside each hose fitting where it connects to the washer, there is a small mesh screen filter. These trap sediment from your home's plumbing. In areas with hard water or older galvanized pipes, these screens clog within 2-3 years and restrict flow to a trickle.

Pull the screens out with needle-nose pliers. Rinse under running water, scrubbing with an old toothbrush to dislodge mineral deposits. If heavily calcified, soak in white vinegar for 30 minutes. Reinstall, reconnect hoses, open valves, test.

3. Are the hoses kinked?

Push the washer back and check that neither rubber hose is sharply bent or crimped behind the machine. A kink creates zero flow on that line. Straighten any bends and ensure at least 4 inches of clearance between the back of the washer and the wall.

If any of these three resolved the issue, your washer will fill normally and F20 will not return. No parts needed, no technician needed.

If Still Showing F20: Deeper Investigation

These quick fixes did not work — the problem is inside the machine. The F20 code specifically means the Whirlpool-built Kenmore washer (model prefix 110.xxxxx) received a signal from the pressure switch indicating the tub water level did not rise above the minimum threshold within the allotted fill time. This implicates four possible internal components.

Important: This guide applies to Whirlpool-manufactured Kenmore washers with the 110.xxxxx model prefix. LG-built Kenmore units (796.xxxxx) display "IE" for inlet water errors. Frigidaire-built units (417.xxxxx) use "E1" for fill timeout. Different manufacturers, different codes, different parts.

Internal Cause 1: Water Inlet Valve Failure

The inlet valve is a dual-solenoid electromechanical valve mounted where the hoses connect to the back of the machine. Each solenoid controls one water temperature (hot or cold). When the board commands a fill, it energizes one or both solenoids, lifting internal plungers off their seats to allow water flow.

Testing the inlet valve:

Unplug the washer. Remove the rear access panel or top panel to access the valve's wire connectors. Disconnect one solenoid connector at a time and measure resistance across the solenoid terminals with your multimeter set to ohms. Expected reading: 500-1,500 ohms per solenoid. An open reading (OL) means that solenoid's coil burned out — no magnetic force, no valve opening.

Also check: with the washer unplugged and hoses connected, open the supply valves. No water should flow into the tub. If water drips or flows with the machine off, the valve's internal seals are degraded — it can stick partially closed as easily as it sticks open.

Replacement inlet valves for Whirlpool-built Kenmore washers run $35-$65. The job requires disconnecting two hoses and one wire harness, removing two mounting screws, and reversing the process with the new valve. Twenty minutes.

Internal Cause 2: Pressure Switch Fault

The pressure switch (also called water level switch) tells the board how much water is in the tub. It connects to the tub via a small rubber air hose. As water rises, it compresses air in this hose, pushing against a diaphragm in the switch. At specific pressure points, the switch clicks over and signals the board.

If the switch is stuck or the air hose is disconnected/cracked, the board never receives the "water is arriving" signal — even if the tub is physically filling. Result: F20.

Testing:

Unplug the washer. Locate the pressure switch (top of machine, usually mounted to the frame near the control panel area). Find the small rubber hose connecting it to the tub — it is typically 1/4 inch diameter clear or black tubing. Check for: disconnection at either end, cracks or splits in the hose, or water inside the hose (indicating a tub-end blockage forcing water up into the air line).

Blow gently into the switch end of the hose — you should hear one or two distinct clicks from the switch as pressure increases, and clicks again when you release. No clicks = failed switch. Mushy, no-click resistance = cracked diaphragm.

Replacement switch: $20-$40. Hose: $5-$10. Both are simple clip-on or push-fit connections.

Internal Cause 3: Flow Meter Malfunction (Select Models)

Some newer Whirlpool-built Kenmore models (roughly 2015+) use an electronic flow meter in addition to or instead of the traditional pressure switch. This turbine-style sensor in the inlet path counts rotations to measure actual gallons entering the tub. If the turbine jams (mineral buildup on the impeller) or its signal wire breaks, the board sees "zero flow" even with the valve open and water actually entering.

Check your tech sheet (inside the machine's cabinet) to determine if your model has a flow meter. If present, it is typically inline with the inlet water path near the valve.

Internal Cause 4: Control Board Inlet Valve Driver

The board's output driver (usually a relay or triac) that energizes the inlet valve solenoid can fail. Symptoms: you hear no click from the inlet valve when a fill should begin, and the valve solenoids test good for continuity. The board is not sending power to them.

This is confirmed by measuring voltage at the valve connector during a fill command (meter on AC volts, probes on the connector pins while the board is commanding a fill). Should read approximately 120VAC. Reading 0V with good solenoids = board driver failure.

Professional Assessment

After attempting the free fixes and checking the inlet valve with a multimeter, you will know whether this is a valve issue ($35-$65 DIY), a pressure system issue ($20-$40 DIY), or a board issue ($150-$280 for the part alone). A professional diagnostic visit runs $80-$120, credited toward repair if you proceed. The value of professional help on F20 is primarily in confirming which component failed before ordering parts — especially relevant when the pressure switch, flow meter, and board are all plausible suspects.

Parts Sourcing

All parts for 110.xxxxx Kenmore washers are Whirlpool OEM parts:

• Inlet valve: W10853723 or equivalent (varies by sub-model)
• Pressure switch: WPW10514214
• Flow meter (if equipped): W10110225

Search by your full model number on RepairClinic or PartSelect for exact matches. Do not use generic "Kenmore inlet valve" searches — you will find parts for the wrong platform.

Important Note About Kenmore Parts Ordering

Because Kenmore is a multi-manufacturer brand (not a maker itself), parts must be ordered by the actual manufacturer's part number — not by searching "Kenmore washer parts." Your model number prefix identifies the real manufacturer:

For washers: the most common Kenmore washer manufacturer is Whirlpool (prefix 110.xxxxx for washers/dryers, 665.xxxxx for dishwashers, 790.xxxxx for ovens). Parts websites like PartSelect and RepairClinic accept your full Kenmore model number and automatically cross-reference to the correct OEM part number. Always verify the part number matches before ordering — similar-looking parts from different manufacturers are not interchangeable even though both machines say "Kenmore" on the exterior.

The Sears Parts Direct website (now Partstown) also stocks these parts but typically at a higher price point than ordering the OEM part directly from an appliance parts wholesaler. Shopping by the OEM part number rather than the Kenmore part number often saves 20-40% on identical components.

Extending Your Kenmore Washer's Lifespan

Regular maintenance prevents many error codes from developing in the first place. For your Kenmore washer, the most impactful maintenance items are:

Monthly: Run a clean cycle (dedicated Clean Washer cycle or hottest cycle with no clothes and a washer cleaner tablet). This dissolves detergent residue and mineral deposits that accumulate in the wash system, drain path, and sensor areas. Residue buildup causes false sensor readings, slow drainage, and reduced cleaning effectiveness.

Every 3-6 months: Clean the inlet screens where supply hoses connect. Hard water areas should clean every 3 months; soft water areas every 6. Also clean the drain pump filter if your model has an accessible one.

Annually: Inspect supply hoses for bulging, cracking, or discoloration. Rubber hoses should be replaced every 5 years regardless of appearance — internal deterioration is invisible until the hose bursts. Upgrade to stainless steel braided hoses for burst protection.

Always: Use the correct amount of HE detergent (if applicable). Check pockets before every load. Do not overload the drum past 3/4 capacity. Leave the door ajar between loads to prevent mold and mildew in the gasket and tub.
