If your Whirlpool Duet front-load washer is displaying an F20 or FH error code, don’t panic! This simply means your machine isn’t detecting any water filling into the tub. It’s a common issue, and often, it’s something you can troubleshoot yourself without needing a technician.
What Triggers This Error?
- Closed water supply faucets (hot and/or cold).
- Clogged inlet screens on the water supply hoses.
- A faulty water inlet valve.
- Low water pressure.
- Kinked or blocked water supply hoses.

Your Step-by-Step Fix Guide
- First things first, check your water supply. Locate the hot and cold water faucets behind your washer and ensure they are fully open. Sometimes, they get accidentally turned off or weren’t fully opened after a previous installation.
- Next, examine the inlet screens. Disconnect the water supply hoses from the back of the washer. At the connection points on the washer, you’ll see small screens. These can become clogged with sediment or debris over time. Clean them carefully with a brush or rinse them under a faucet. Reattach the hoses securely, making sure there are no kinks.
- If the above steps don’t resolve the F20/FH code, the issue likely points to the water inlet valve itself. This valve controls the flow of water into your washer. You’ll need a multimeter to test its solenoids for continuity. Disconnect the power to your washer, locate the water inlet valve (usually at the back, where the hoses connect), and remove the electrical connectors from the solenoids. Set your multimeter to read ohms and touch the probes to the terminals of each solenoid. A healthy solenoid will typically show a reading between 500 to 1200 ohms. If a solenoid shows an open circuit (OL) or a very low/high reading outside this range, the valve is faulty and needs replacement.
