How to Fix Whirlpool Washer Error F20
Problem: No water detected entering washer during fill cycle

How to Fix Washer Error
1. Verify both hot and cold water supply valves are fully open.
2. Disconnect fill hoses from washer inlet valves and place in bucket.
3. Turn on water supply briefly to verify adequate flow (should fill bucket rapidly).
4. Clean inlet valve screens by removing hoses and brushing debris from brass fittings.
5. Check for kinks in fill hoses or excessive length (>6 feet restricts flow).
6. Access inlet valve assembly behind rear panel – test solenoid coils with multimeter (should read 500-1500 ohms).
7. If solenoids test open/infinite resistance, replace water inlet valve assembly W
8. Verify pressure switch hose is connected and not leaking air (causes False ‘full’ detection).
9. Test operation with both hot and cold cycles to confirm proper fill.
10. If water flows but error persists, replace pressure switch W

How to Fix Whirlpool Washer Error F13
Problem: EEPROM checksum error on main control board

How to Fix Washer Error
1. Unplug washer for 10 minutes to fully discharge board capacitors.
2. Remove top panel and locate main control board (CCU).
3. Inspect board for visible damage: burnt components, bulging capacitors, or moisture corrosion.
4. Check all wire harness connections for proper seating and corrosion.
5. Verify 120V AC power supply to board is stable (no voltage sags during operation).
6. If board appears physically intact but error persists after power cycle, EEPROM corruption has occurred.
7. Main control board must be replaced – EEPROM cannot be reprogrammed in field.
8. Install new CCU W10461397 and secure all mounting screws to prevent vibration damage.
9. After installation, run full diagnostic cycle to verify all functions operate correctly.
10. Note: Power surges often cause this failure – recommend installing whole-house surge protector.

How to Fix Washer Error
1. Unplug washer for 2 minutes to reset communication bus.
2. Remove top panel and locate main control board (CCU) in upper right corner.

4. Inspect harness for pinched wires between tub and cabinet.
5. Remove rear panel to access MCU and verify its communication connector is fully seated.
6. Check for water damage or corrosion on both boards’ communication ports.
7. Measure resistance between communication lines (should be 100-120 ohms between data lines).
8. If harness tests good but error persists, replace MCU W10312695 first (less expensive).
9. If F11 returns, replace main control board W
10. After repair, enter diagnostic mode and verify all communication LEDs function properly.

How to Fix Whirlpool Washer Error F10
Problem: Motor control unit internal failure or communication timeout

How to Fix Washer Error
1. Power cycle washer by unplugging for 5 minutes.
2. Remove rear access panel to expose motor control unit (MCU).
3. Inspect all connectors at MCU for corrosion, bent pins, or loose seating – reseat firmly.
4. Check 3-wire serial communication harness between MCU and main control board (CCU) for damage.
5. Verify 120V AC power reaches MCU during operation (test at L1/L2 terminals).
6. Measure DC voltage at MCU output to motor (should be 30-150V DC variable depending on speed).
7. If power present but no motor operation, replace MCU assembly W
8. After replacement, run diagnostic mode verifying communication handshake between CCU and MCU.
9. If F10 returns after MCU replacement, suspect main control board failure requiring CCU replacement.

How to Fix Whirlpool Washer Error F09
Problem: Overflow condition detected – pressure switch stuck closed or control board fault

How to Fix Washer Error
1. Unplug washer immediately to prevent flooding.
2. Check base pan for standing water indicating actual overflow.
3. Remove top panel to access pressure switch mounted on right side wall.
4. Disconnect pressure hose from switch and blow through it to clear moisture/debris.
5. With hose disconnected, multimeter should show NO continuity across switch terminals.
6. Reconnect hose and gently blow into it while monitoring continuity (should close at ~
7. 5 PSI).
8. If switch stuck closed (always shows continuity), replace pressure switch W
9. Inspect pressure hose for cracks, kinks, or water accumulation (replace if damaged).
10. If switch tests good but error persists, replace main control board W
11. After repair, run diagnostic cycle monitoring water level detection.
