Error code E8 on a Haier washing machine

Just a few minutes after starting a cycle, the user may notice the E8 error code on their Haier washing machine. What malfunction does this error code indicate? Will they be able to repair the washing machine themselves, or will they need to call a technician? Let's explore the details.

We are looking for the source of the problem

This error appears on the display in the first minutes after the cycle starts. Code E8 indicates problems with water intake. The washing machine cannot fill to the required level within the allotted time, so the wash cycle is interrupted.

Without water, the wash cycle won't start, causing the machine to freeze. First, it's recommended to check that the main water supply to your home is turned on. Next, check to see if the shut-off valve upstream of the washing machine is closed. Third, ensure the door is tightly closed. If the system is leaking, the electronic module won't prompt the washer to fill.

Water will not fill if the washing machine door is not completely closed.

If there's water in the pipes, the pressure is normal, the valve is open, and the hatch door locks, the problem lies deeper. You'll need to run an extended diagnostic on your Haier washing machine. The E8 error code can be caused by a pinched inlet hose, a clogged filter, or a damaged control module.

The check progresses from simple to more complex. We'll explain what problems can trigger the E8 error.

• The inlet hose is clogged. This is one possible cause. Check the hose; it may be kinked, preventing water from entering the washer.
• The coarse filter is clogged. It is installed before the inlet hose. If the element is heavily clogged, water intake into the system becomes impossible. Cleaning the nozzle may help.
• The mesh filter is clogged. The element is located in front of the inlet valve. The metal mesh becomes clogged with impurities found in tap water, causing a buildup of scale. This causes the washing machine to make a loud humming noise when filling with water. Cleaning the inlet filtration system will solve the problem.
• The inlet valve is faulty. This is responsible for filling the system with water. If you've noticed that detergent isn't being completely rinsed out of the detergent drawer during washing, be sure to check the solenoid valve. Diagnostics are performed by applying 220 volts to the component. A properly functioning component will short-circuit, indicating this with a distinctive click. This component cannot be repaired; it will need to be completely replaced.
• Pump failure. If the electronics detect a pump failure, it will not prompt the machine to fill with water. This is logical, as the washing machine cannot drain the used liquid.
• Water level sensor failure. When the pressure switch malfunctions, the control module can't determine how much water is in the tank. For example, the tank might be full, but the sensor is reporting an empty tank. In this case, the display also displays error E8.
• Damage to the pressure switch hose. This component is subject to natural wear and tear. Over time, the hose wears out, leaks air, and loses its seal. Pressure issues arise, causing the unit to malfunction.
• Control module failure. If the electronic unit is damaged, the machine's behavior will be unpredictable. The washing machine may display any error code, including E8. A board diagnostic will be required.

Most problems can be resolved without calling a technician, by yourself. This includes clogs and replacing individual components. If the problem lies with the electronic module, you'll need the help of a service center specialist.

Check the warranty first

If a recently purchased machine gives an error, don’t even try to fix it yourself. For all washing machines Haier A one-year warranty applies – during this period, you can contact the service center for free diagnostics and repairs. If you open the washing machine's casing before calling a technician, you won't be able to claim warranty service.

If the warranty has long expired, it's best to first try to fix the problem yourself to avoid overpaying a technician. Moreover, the E8 error is usually not related to any serious problems. First, check to see if there's water in the pipes, if the hatch door is tightly closed, and if the inlet hose is kinked. If all is well, a more in-depth diagnosis begins.

Troubleshooting algorithm

The E8 message appears on the Haier washing machine's display at the very beginning of the cycle, while the machine remains empty. This simplifies the process—the user doesn't have to figure out how to drain the water from the washing machine before the diagnostic. All that's required is to disconnect the power to the machine.

Before you begin diagnosing your Haier washing machine, disconnect the power supply and close the shut-off valve.

Now we can begin diagnostics. Remember, testing starts with the basics. Make sure:

• there is water in the pipes;
• the shut-off valve in front of the washing machine was not closed when you started the cycle;
• the inlet hose is not pinched or kinked;
• the hatch door is closed completely.

Next in line to check are the filters. First, get to the filter mesh installed in front of the fill valve. Here's how to do it:

• detach the inlet hose from the washing machine body;
• find a mesh filter;
• Use pliers to grasp the special protrusion on the filter element and pull out the mesh;
• rinse the nozzle under water, clean off the plaque;
• Return the filter to its original place, using pliers.

Next, check the coarse filter. It's located immediately after the shut-off valve, before the washing machine's inlet hose. A pair of wrenches will be needed to remove the element. One should hold the connection with the faucet, and the other should loosen the retaining screw.

Water will leak out during the removal process. Therefore, it's best to have a basin and rags ready. The coarse filter will flush itself under high pressure; just wait about a minute and then tighten the bolt.

Let's check the intake valve

In most cases, the E8 code indicates a faulty inlet valve. The element fails, the membrane doesn't open, and water doesn't flow into the washing machine. In this situation, repair is impractical; it's much more reliable and cost-effective to replace the part yourself.

A new inlet solenoid valve for a Haier washing machine costs about $5. This is a genuine, high-quality part. Replacing the element is quite simple. Here's the procedure:

• de-energize the washing machine, close the shut-off valve;
• disconnect the inlet hose from the machine;
• Unscrew the two bolts holding the top cover of the washing machine;
• remove the top panel of the case and put it aside;
• find the inlet valve (it is located where the inlet hose connects to the body);
• Take a photo of the connection diagram of the wires and pipes to the element;
• unhook the pipes from the valve, disconnect the power supply wiring;
• unscrew the valve retaining bolt;
• remove the element from the washing machine housing;
• put the new solenoid valve in place and secure it with a bolt;
• connect the pipes to the element, connect the wiring (referring to the photo);
• put the washing machine housing cover back in place;
• connect the inlet hose to the washing machine;
• Open the shut-off valve.

Once the repair is complete, run a short test cycle with no laundry in the drum. If the Haier machine begins to fill with water, the problem is solved. You can then use the washing machine as usual.

If the above steps don't help, check the pressure switch. The level sensor nipple may be clogged. Cleaning the tube or replacing the element completely will help. If the problem lies in the control module, it's best not to take any risks. Working with electronics requires specific skills and knowledge, so it's recommended to entrust diagnostics and repairs to professionals.
