Whirlpool Washer Error Code F13

Whirlpool Washer Error Code F13 — What It Means

The F13 code on a Whirlpool washer typically indicates a problem with the machine taking too long to fill with water (a “long fill” condition) or a fault related to the water fill/fill monitoring system. When the washer cannot detect proper water flow or reach the required fill level within the expected time, the control board triggers F13 and pauses or stops the cycle. This condition affects wash performance — clothes may not get enough water, detergents may not dissolve or rinse properly, and cycles can fail to start or complete. It also causes longer cycle times as the machine retries or waits. In some situations poor filling can lead to unbalanced loads, ineffective cleaning, extra energy/water usage, or repeated cycle interruptions. While F13 is usually not immediately dangerous, trying to bypass electrical or plumbing faults without proper precautions could create safety hazards such as electrical shock or water damage.

Common Causes

• Closed or partially closed water supply valves (hot or cold)
• Kinked, pinched, frozen, or clogged inlet hoses
• Blocked inlet screens/filters in the water inlet valve
• Faulty or weak water inlet valve (doesn’t open fully)
• Low household water pressure or intermittent municipal supply
• Disconnected, clogged, or damaged water level/pressure hose
• Malfunctioning water level pressure switch or sensor
• Faulty flow meter (on models that use flow sensing)
• Control board or wiring harness faults (communications or relay failures)
• Blocked or damaged external plumbing (screened faucet aerators, filters, or home plumbing valves)

Troubleshooting Steps

1. Power reset: Unplug the washer (or switch off the breaker) for 1–2 minutes, then restore power to clear temporary electronic glitches.
2. Check household water: Ensure both hot and cold water supply valves are fully open and that other fixtures have normal pressure.
3. Inspect inlet hoses: Look for kinks, pinches, or ice. Disconnect hoses and check for internal debris or restrictions.
4. Clean inlet screens: Turn off water, disconnect hoses from the washer, and gently clear the small mesh screens in the inlet valve using a soft brush and water.
5. Test inlet valve operation: With the washer powered and in a diagnostic or fill test mode (refer to your model’s tech sheet), confirm the inlet valve opens and water flows. If valve does not activate or flow is weak, replace the inlet valve.
6. Check the pressure hose and switch: Inspect the small pressure hose between the tub and the pressure switch for cracks, blockages, or disconnection. Replace or reseal if damaged.
7. Run diagnostics: Enter the washer’s diagnostic/self-test mode (refer to model manual) to read live sensor values and confirm whether the pressure switch, flow meter, or inlet valve is reporting correctly.
8. Measure continuity (advanced): If comfortable working with electronics, power off and test continuity of the inlet valve coils and pressure switch using a multimeter. If unsure, skip and call a technician.
9. Inspect wiring and connectors: Look for loose connectors, burnt terminals, or damaged wire harnesses between the inlet valve, pressure switch, and control board.
10. Replace suspect parts: If diagnostics identify the inlet valve, pressure switch, flow meter, or control board as faulty, replace the defective part. Start with inexpensive parts (screens, hoses, inlet valve) before the control board.
11. Call a professional: If troubleshooting steps don’t resolve the F13 code or you’re uncomfortable with electrical tests and part replacements, contact an authorized Whirlpool service technician.

Maintenance / Prevention Tips

• Keep water supply valves fully open during use and periodically check they move freely.
• Inspect and replace old inlet hoses every 5 years or sooner if damaged.
• Clean inlet valve screens annually to prevent mineral buildup and debris blockage.
• Use stainless-steel braided hoses to reduce risk of kinks and burst hoses.
• Avoid over-tightening hoses at the connections — overtightening can damage threads and screens.
• Run a maintenance wash monthly (empty hot cycle with washer cleaner) to reduce residue buildup.
• Keep the small pressure hose and its connections dry and free from detergent buildup.
• If you have softeners or well water, install a pre-filter to reduce sediment entering the washer.
• Check home water pressure; install a booster or pressure regulator if pressure is consistently low or high.
• Avoid turning off water at the faucet frequently; repeated on/off can stress valves and fittings.
• Replace worn or cracked rubber hoses and pressure tubes immediately.
• When moving the washer, support hoses and wiring to prevent stretching or kinking.
• Schedule periodic professional inspections if your washer is heavily used (e.g., large households).
• Follow the manufacturer’s recommended parts and installation methods if replacing components.
• Keep the area behind the washer accessible for quick inspection of hoses and valves.

FAQs

Q: Can I ignore an F13 error and keep using the washer?

A: It’s not recommended. F13 indicates a fill or sensing problem that can prevent proper cleaning, may stall cycles, and risks water damage if the washer repeatedly tries to fill or runs incorrectly. Address the cause promptly.

Q: How much does it cost to fix an F13 error?

A: Costs vary by part and labor. Simple fixes like cleaning screens or replacing hoses are inexpensive (parts under $30). Replacing an inlet valve or pressure switch costs more ($40–$150 parts range) plus labor. Control board repairs can be the most costly. Get quotes from authorized technicians for an accurate estimate.

Q: Is the F13 error covered under warranty?

A: Coverage depends on your washer’s warranty status and the repair cause. Manufacturing defects may be covered, but damage from hard water, neglect, or home plumbing issues typically is not. Check your warranty documents or contact Whirlpool support.

Q: Can I replace the inlet valve myself?

A: If you have basic appliance repair skills, can shut off power and water, and follow the model-specific service manual, you can replace the inlet valve. If not comfortable working with electrical connections or diagnostics, hire a professional.

Conclusion / Safety Notice

F13 on a Whirlpool washer usually signals a fill or fill-sensing problem that can often be resolved by checking water supplies, cleaning inlet screens, and inspecting hoses and pressure tubing. While many homeowner-level checks are safe (turning off water, inspecting hoses, cleaning screens), electrical testing or replacing control components should be done with power disconnected and, preferably, by a qualified technician. If you encounter unclear diagnostics, persistent errors after basic troubleshooting, signs of water leaks, or you are unsure about electrical safety, contact an authorized Whirlpool service technician. Attempting advanced repairs without proper training can create electrical shock, fire, or water-damage risks.

When in doubt, stop, turn off power and water, and call a professional. Fast action and safe repairs will get your washer back to reliable operation and help prevent repeat occurrences.
