The screen on the washing machine is flashing

Almost all modern washing machines have screens (displays) or illuminated buttons (sometimes numbers) for electronic control. However, sometimes washing machine owners encounter the following problem: the washing machine screen (or buttons/numbers) flickering. This malfunction is very common, especially among those who use the appliance frequently. Let's take a closer look at the problem.

Reasons for the display board flickering

If you notice flickering or visible flashing of the screen or individual letters or numbers, it means the appliance is trying to get your attention by indicating a malfunction. Don't frantically turn the washing machine on and off in an attempt to make the indicator disappear. But what should you do then? First, try to understand the cause of the malfunction.

The code table included with your washing machine's manual can help clarify the situation. It explains all possible error codes. If you don't have this table, try to find a similar table online; you'll definitely need one.

Important! Don't attempt any DIY repairs until you've determined the problem. You risk further damaging the device and incurring significant financial costs.

If the display shows no information, or flashes on and off intermittently, the problem is most likely related to a semiconductor component in the control module. Even if you suspect this is the cause, you should not attempt repairs yourself. We recommend entrusting the device to an experienced technician who will perform a thorough diagnosis and repair.

Common error codes

Is the display showing an error code? There's no problem with the display; the malfunction is due to a problem inside the machine. Deciphering the code will help you figure out what's wrong with the machine. The self-diagnostic database of modern washing machines contains dozens of codes. Let's look at the most common ones.

Heating element malfunction. The abbreviation "TEN" stands for tubular electric heater. In short, the heating element is one of the most vulnerable components in any large household appliance. The coating used on tubular electric heaters is often of poor quality. As a result, deposits form on the heating element, the coil quickly becomes coated with a very thick layer of deposits, and can overheat and fail. The system will respond with a code. The problem is solved by replacing the tubular electric heater.

A broken drain. Drainage-related problems are among the most common malfunctions. A drain can easily become clogged, but the drainage system can also break. This can happen due to debris getting in. Perhaps you washed clothes heavily soiled with sand or forgot to remove debris from your pockets. To fix the problem, inspect the drainage system to determine the exact location of the problem.

Clogged or broken pressure switch. The pressure switch is the water level sensor. It may be broken or heavily clogged. This prevents the machine from accurately assessing how full the tank is. To confirm this, you can run a quick diagnostic. Simply follow our quick instructions for assessing the tank's fullness.

1. Disconnect the machine from the mains and water supply.
2. Unscrew and set the top cover aside.
3. On the right wall you will find a pressure switch - this is a plastic "box" that has a long tube attached to the tank.
4. Unhook the hose from the pressure switch housing.
5. You need to blow hard into the place where the tube (fitting) connects to the level sensor.

The air flow will close the contacts, and if the device is working properly, it will respond with a couple of clicks. If it's broken, you won't hear any sound. However, if you want to continue diagnosing, inspect the hose for blockages or damage. If there's a blockage, simply rinse the hose under the tap. You can also test the device with a multimeter, if you know how to use one.
