No matter how expensive or fancy your washing machine is, it is going to throw tantrums one day or another. It’s not a future prediction but a known fact. It could be strange noises, drainage problems, or simply refusing to start – it is difficult to deal with them. The first reaction and thought is to get it up and running as soon as possible by calling for help. But, there is a built-in solution in your machine: the diagnostic mode.
This mode is your very own washing machine troubleshooting guide. It will help you find out where and what is wrong with your machine, all on its own. All you have to know is how to enter your machine’s diagnostic mode and check if you can solve the problem. This gives a simple solution that saves both time and money.
What is Diagnostic Mode?
This mode helps you understand your washing machine’s problems in a simple way. It is like having a conversation with your machine. Instead of random beeps, flashing lights, or a complete shutdown, this will give you actual error codes that tell you about specific problems.
Each and every washing machine has a diagnostic mode – be it an older or a newer model. The older versions needed a series of complex actions, meanwhile, the new ones have simplified it.
Every brand has a different way of entering the diagnostic mode. Here’s a list of some of the major brands:
Whirlpool
- Start with your machine turned off.
- Switch on the machine, and quickly turn the select cycle knob 360 degrees.
- Then press the Start/Pause button three times.
- This should activate the control panel lights and they will start flashing. It means that you have entered Whirlpool’s washing machine diagnostic mode.
- When you are running the self-test, the display will show different codes.

Common Error Codes and What Do They Mean
After entering the diagnostic mode, your washing machine will run different tests. You will start to see error codes coming up on display indicating the problem. Just like different brands have different ways of activating the mode, they also have different error codes.
Whirlpool Codes
F01: Electronic Control Board Failure
There is a problem with your machine’s main control system. This happens if there are loose connections, board faults, or because of irregular power supply. You can reset it through a simple power reset.
F05: Drain Pump Failure
This suggests drainage system problems. Most commonly, something is stuck in the drain, pump motor issues or blocked drain hoses. All you need to do is remove if anything is stuck in the pump system. You can also check for kinks in the drain hoses.
Samsung Errors
4C: Water Supply Issues
This points to the machine’s water intake system. This happens because of insufficient water pressure, blocked inlet filters or broken water inlet valves. You need to regularly maintain the inlet screens to avoid this problem.
5C: Drainage Problems
If the diagnostic mode shows this code, then there are problems with water evacuation from the machine. Check for improperly installed drain hoses, pump blockages, or other drain pump malfunctions. Position the hose properly and regularly clean it to prevent these issues.
LG Warning Signs
DE: Door Errors
This means there are issues with your machine’s door-locking mechanism or the sensor system. These mostly happen because of scrap in the locking mechanism, misaligned doors, or electronic sensor failures. Remember to clean your door seal and lock mechanism regularly.
UE: Unbalanced Load Warnings
There is improper weight distribution in the drum. This error shows up when heavy items are mixed with lighter clothes and they get tangled during the wash cycle. Make sure to evenly distribute the loads.

Maytag Codes
LF: Long Fill Error
This comes up on display when the washer is taking too long to fill with water. Most Maytag machines fill in 8-10 minutes. It could happen because of low water pressure, blocked inlet screens or damaged inlet valves. Check these things to solve this error.
F09: Overflow Condition
This code means that the washer has too much water in the drum. You could have a stuck water inlet valve that continues to fill the water even when it should stop. Check for a clogged or incorrectly installed drain hose or a faulty water level pressure switch that is not reading the water levels.
Bosch Warnings
E20: Drainage Issues
This error means there is something wrong with the pump or the drainage system is blocked. Check if something is stuck in the filter or the drainage pathway. This error can also mean there are pump motor issues.
E15: Faulty Temperature Sensors
This code means your washing machine is having issues with temperature sensors or other electrical troubles. Usually, there is faulty wiring or a damaged control board. You can restart the machine and take a look at the wiring.
