Error code F01 in a Hisense washing machine

Almost all modern automatic washing machines can detect internal malfunctions and immediately notify the user. Error F01 in a Hisense washing machine appears on the display 4-6 minutes after starting the cycle. At this point, the machine freezes, and further washing is impossible.

What problem does the F01 error code indicate? Can I repair the washing machine myself? What causes this error? Let's look into the details.

What fault caused F01?

What problem does the error indicate? Fault code F01 indicates that the washing machine cannot draw in the required amount of water within the allotted time. The reasons may vary, from a closed tap on the pipe to damage to the control board.

First of all, check if there is water in the pipes, if the pressure is sufficient, and if the shut-off valve in front of the machine is not closed.

Perhaps the water supply in the house was turned off, causing the washing machine to display error code F01. If the water pressure is weak and only a trickle comes out of the faucet, the machine won't fill in the allotted time. Therefore, first rule out all external causes.

If the water supply is fine, the problem will need to be looked for inside the washing machine. Let's look at why a Hisense machine might display error code F01.

• The inlet valve is broken. This is where water enters the washing machine. To check the part, apply 220V to it. If all is well, you'll hear a distinctive click (indicating that the circuit is closed and the mechanism is operating). A faulty valve can't be repaired; it's easier to buy and install a new one.
• The inlet filter is clogged. The mesh screen is located where the inlet hose connects to the machine body. A buildup of scale forms on the metal screen, slowing down the water flow into the machine. The filling process is accompanied by an unusual buzzing sound. Cleaning the filter element will solve the problem.
• The water level sensor is faulty. A malfunctioning pressure switch can trigger the F01 error and freeze the machine. It will signal the module that the tank is full, which is not true. The "brain" will stop filling with water, but the wash cycle will not start. To check the element, disconnect the tube from it and blow into it. You should hear a steady clicking sound. If there is no clicking sound, the sensor is faulty and will need to be replaced.
• A section of the control board is damaged. The washing machine's "brain" controls all processes, including water intake. If any of the adapters burn out, the cycle is interrupted and the machine displays an error. Diagnosing the electronic unit is a complex task, and it's impossible to handle without knowledge and experience. Therefore, it's best to entrust microprocessor repair to specialists.
• The pump has burned out. At the beginning of the cycle, the pump must transmit a signal to the electronic module indicating it is ready to pump water from the tank to the sewer. Without this information, the "brain" will not begin filling. If the drain pump has burned out, the only solution is to replace it.

Most often, the F01 error is caused by a broken inlet valve, a clogged filter, or a faulty water level sensor.

Another possible cause is a faulty door lock. If the door isn't closed properly, the machine won't fill with water. Therefore, make sure the system is sealed before starting the cycle.

Be sure to check the wire running from the pressure switch to the tank. Due to normal wear, it may begin to leak air. This will interfere with the water level sensor.

How to troubleshoot a problem yourself?

If you notice your washing machine displaying the F01 error code, don't panic. First, make sure the water supply hasn't been shut off. It's possible the utility company simply shut off the water supply due to an accident, and the problem isn't with the washing machine at all.

Also, make sure the shutoff valve at the inlet to the washing machine is open. Check that the inlet hose isn't kinked. If all is well, then the problem is indeed with the washing machine.

If you bought an automatic car recently, it is better not to perform self-diagnostics. Service center specialists will check your washing machine and repair it free of charge under warranty. If you open the case yourself, the warranty card will be void.

Before beginning diagnostics, unplug the Hisense washing machine and turn off the water supply valve. First, check the inlet hose. Disconnect it from the pipe and the washing machine body, and rinse it under running water. Next, clean the mesh filter. The metal screen becomes clogged with dirt and prevents liquid from flowing through. Here's how to proceed:

• find the mesh filter, it is located in front of the inlet valve;
• Use pliers to grasp the protrusion on the filter and remove the metal part;
• clean the mesh from plaque and dirt (using a toothpick or toothbrush);
• put the filter back in place.

The problem could also be with the coarse filter. It's installed after the shut-off valve, before the washing machine's inlet hose. Clean the element as follows:

• take two wrenches;
• Place a large container under the valve and cover the floor with rags;
• Use one wrench to hold the joint and the other to unscrew the nut.

After this, water will flow from the joint. The stream will flush the coarse filter. Then all that remains is to tighten the nut back.

You can check the pressure switch yourself. It's located under the top panel of the housing. The first step in diagnosing it is to disconnect the pressure tube and blow into the hose. If you hear clicking sounds, the level sensor is working properly. The second step is to test the element with a multimeter.

It's best to entrust repair and diagnostics of the control module to specialists. Working with the board requires specific knowledge and skills. Understanding the numerous semiconductors and circuits will be difficult for the average user.
