Resetting The Washer
Resetting the Whirlpool washer can clear the F20 error code in many cases. This process restarts the machine’s system and removes minor glitches. It is often the first step to try before calling a technician. Simple reset methods can save time and money.
Soft Reset Method
Press the Pause/Cancel button twice quickly. This action attempts a soft reset. It interrupts the current cycle and restarts the washer’s control board. The soft reset does not cut power but refreshes the machine’s system. It may clear small errors causing the F20 code.
Hard Reset Method
Unplug the washer from the power outlet. Leave it unplugged for at least five minutes. This allows the control board to fully reset. After waiting, plug the washer back in and turn it on. The hard reset removes power from the machine, which can fix deeper issues.
Unplugging For Temporary Glitch
Sometimes, a temporary glitch triggers the F20 code. Unplugging the washer for a short time can clear this. Wait about one to two minutes before plugging it back in. This quick power cycle can reset the electronics. It is a simple step that often restores normal function.
Inspecting Water Supply
Inspecting the water supply is a key step to fix the Whirlpool Washer F20 code. The code often points to water flow problems. Checking the water source helps find blockages or issues.
Start by making sure water reaches the washer properly. Look at faucets, hoses, and inlet screens. These parts control water entry into the machine. Clean and fix them to restore smooth water flow.
Check Faucets
Look at the faucets behind the washer. Both hot and cold water valves must be fully open. If they are partly closed, water flow will reduce. This can trigger the F20 error.
Turn the faucets all the way counterclockwise. Listen for water running sound. No sound means a supply problem. Fix this before moving on.
Examine Inlet Hoses
Inspect the water inlet hoses for kinks or bends. A bent hose blocks water flow. Straighten any sharp bends to allow water through.
Look for cracks or leaks on the hoses. Damaged hoses reduce pressure and cause errors. Replace any hose that looks worn or damaged.
Clean Water Inlet Screens
Turn off the water supply and unplug the washer. Disconnect the water inlet hoses from the machine.
Inside each hose connection, find the small filter screens. These screens catch dirt and debris. Remove and rinse them under running water.
Use a soft brush if needed to clear buildup. Dirty screens limit water flow and cause the F20 code.
Addressing Water Inlet Issues
Water inlet issues often cause the Whirlpool washer F20 error code. This code signals a problem with the machine filling water properly. Addressing these problems quickly can prevent damage and ensure the washer works smoothly. Understanding the common causes helps fix the issue effectively.
Replace Faulty Water Inlet Valve
The water inlet valve controls water flow into the washer. A faulty valve may block water from entering. Check the valve for any signs of damage or wear. If it is broken or clogged, replace it with a new one. Use a compatible valve to avoid further problems. Disconnect power before replacing the valve to stay safe.
Test Pressure Switch
The pressure switch senses water level inside the washer tub. If it fails, the machine may not detect water correctly. Test the switch using a multimeter for proper function. Replace the pressure switch if it shows no continuity or has defects. This step ensures the washer fills and stops at the right water level.

Checking Drainage System
Checking the drainage system is key to fixing the Whirlpool Washer F20 error code. The F20 code often signals a problem with water draining properly. This can cause the washer to stop mid-cycle or display an error. Examining the drainage parts helps find and fix blockages or damage. This keeps your washer running smoothly and prevents future errors.
Start by looking at the drain hose, pump filter, and drain tube. These parts often collect lint, debris, or small objects that block water flow. Clearing these blockages is simple and can save you from costly repairs. Follow these steps to check each component carefully.
Clear Drain Hose Blockages
Disconnect the drain hose from the back of the washer. Check the hose for kinks or bends that stop water flow. Run water through the hose or use a long, flexible brush to remove clogs. Clear any dirt, lint, or small objects stuck inside. Reattach the hose securely to avoid leaks.
Clean Drain Pump Filter
Locate the drain pump filter near the bottom front of the washer. Open the filter cover carefully to avoid water spills. Remove any debris, coins, or lint caught in the filter. Rinse the filter under running water to clean it thoroughly. Replace the filter and close the cover tightly to ensure proper sealing.
Inspect Drain Tube For Obstructions
Find the drain tube connected to the drain pump. Look inside the tube for any visible blockages. Use a flexible tool or pipe cleaner to push out dirt and buildup. Make sure the tube is not bent or crushed. A clear drain tube allows water to flow freely and prevents the F20 error.
Control Board Troubleshooting
Control board troubleshooting is key when facing the Whirlpool washer F20 code. This code often points to a problem with water filling or sensing. The control board manages these functions and any fault here can stop the machine from working properly.
Checking the control board involves careful observation and simple tests. It helps confirm if the control board is the main issue or if other parts need attention. Understanding this can save time and avoid unnecessary repairs.
Identify Control Board Malfunction
Look for signs like unresponsive buttons or error codes that repeat after resets. Check for burnt components or a strong smell near the board. These are clear signals of a control board problem.
Use a multimeter to test the board’s voltage and continuity. No power or broken circuits indicate a fault. Also, check all wiring connections for looseness or damage.
Consider Professional Repair
Control board repairs require skill and special tools. Incorrect handling can cause more damage or electric shock. Professionals have the right knowledge to fix or replace the board safely.
Hiring a technician ensures proper diagnosis and long-term repair. It also keeps your washer under warranty if applicable. This option prevents future breakdowns and improves machine reliability.
