What is Whirlpool Washer F20 Error Code?
The whirlpool washer error code F20 typically indicates a water inlet problem in a device or appliance. This error suggests that there is either no water entering the system or an insufficient water supply for proper functioning. It is important to check the water source, such as the water valve or faucet, to ensure it is turned on and providing an adequate water flow.
Additionally, it is recommended to inspect the water inlet hose or pipe for any blockages or kinks that may be restricting water flow. Resolving the water inlet issue should help restore proper functionality to the device or appliance displaying the F20 error code.
Reasons for Whirlpool Washer F20 Error Code
Inspect the Water Hoses
Begin by examining the water hoses for any signs of bending, kinking, or blockages that could hinder water flow. Ensure that the hoses are securely connected and not loose. Clean the hoses by disconnecting them and running water through to check for any obstructions or leaks. Reattach the hoses securely, ensuring they are positioned correctly for unobstructed water flow.
Verify Water Pressure
Confirm that the water pressure is adequate and not below 10 psi. You can contact your water utility company to obtain the pounds-per-square-inch (psi) level or use a water pressure gauge to measure it yourself by attaching the gauge to the faucets.
Use High-Efficiency Detergent
Make sure you are using high-efficiency detergent designed for washing machines. Non-high-efficiency detergents can create excessive suds, which may prevent the washer from detecting water flow and trigger the F20 error code. If you are already using the correct detergent, proceed to the next step.
Check Water Faucets
Ensure that both the hot and cold water faucets are fully open. Inadequate water supply to the washing machine can occur if the faucets are not turned on properly. Verify that both faucets are completely open or install a "Y-connector" if you only intend to use cold water. Once the faucets are confirmed to be open, proceed to the final step.
Clear the Error Code
To clear the F20 error code, try pressing the "pause/cancel" button twice. Note that in certain LG washing machine models, the machine may start draining after being turned back on. Allow 8 to 10 minutes before attempting to press "pause/cancel." If this doesn't resolve the issue, unplug the washing machine from the power source for at least one minute. Plug it back in, turn it on, select a cycle, and press the "start" button.
If the F20 error code persists after following these steps, it is recommended to seek assistance from a qualified technician to inspect your washing machine.
How to Fix Whirlpool Washer F20 Error Code?
1. Water supply valves are in the closed position:
If your washing machine is displaying the F20 error code, it means that it is not receiving water. The first thing to check is whether the water supply valves, both for hot and cold water, are fully opened. Ensure that both valves are turned on to allow a sufficient water supply to the washing machine, which may resolve the F20 error code.
2. Water inlet hoses are bent or obstructed:
Inspect the water inlet hoses to ensure they are not twisted or blocked. Make sure that water can flow freely through the hoses without any obstructions. In the next step, we will address cleaning the water inlet screens.
3. Water inlet screens are clogged:
The washing machine's water inlet valves have screens to prevent debris from entering the machine through the water supply. If the F20 error code persists and there is inadequate water flow, it is possible that the screens on the inlet valves are clogged. Clean the screens by turning off the water supply, disconnecting the inlet hoses, and removing any debris from the screens. Reconnect the hoses and turn on the water supply to see if the F20 error code is resolved.
4. Control board malfunction:
If there are no issues with the water supply, the F20 error code may be due to a control board glitch. Resetting the washing machine can sometimes resolve such glitches. You can try pressing the Pause/Cancel (or Enable/Disable) button twice to initiate a reset. If the machine starts draining during the reset process, it is normal and part of the reset. Alternatively, you can perform a hard reset by disconnecting the power to the washing machine for a few minutes. Reconnect the power and check if the F20 error code has cleared. If the error code returns, further troubleshooting may be needed.
5. Defective pressure switch:
The pressure switch in the washing machine regulates the water level in the drum. If there is a blockage in the hose or chamber connected to the pressure switch, it can prevent proper water level detection and trigger the F20 error code. Check the hose and chamber for any blockages or damage. Additionally, the pressure switch itself may be electronically faulty and require testing with a multimeter for continuity. To access the pressure switch, remove the top panel of the washing machine, disconnect the chamber and wiring harness, and test the pressure switch accordingly.
Causes of Whirlpool Washer F20 Error Code
1. Water supply issues:
The washer may not be receiving sufficient water due to closed or partially closed water supply faucets. Ensure that both the hot and cold water faucets are fully open.
2. Kinked or blocked water inlet hoses:
Check the inlet hoses connected to the washer for any kinks or obstructions. Straighten any kinks and clear any blockages to allow proper water flow.
3. Clogged inlet valve screens:
The water inlet valves have screens to prevent debris from entering the washer. Over time, these screens can become clogged, affecting water flow. Clean the screens if they are dirty or blocked.
4. Low water pressure:
Insufficient water pressure can trigger the F20 error code. Verify that your home has adequate water pressure. If the water pressure is too low, it may require addressing the issue with your water supply system.
5. Faulty pressure switch or control board:
In some cases, a malfunctioning pressure switch or control board can cause the F20 error code. These components may need to be inspected and replaced by a qualified technician if necessary.
It's important to note that these are general causes, and specific troubleshooting steps may vary depending on the model of your Whirlpool washer. Consulting the appliance's user manual or contacting Whirlpool customer support can provide further assistance in diagnosing and resolving the F20 error code.
