Error code F03 in a Hisense washing machine

What problem does error F03 indicate in a Hisense washing machine? The error code appears on the display when the machine is unable to drain. Can you repair your "home helper" yourself? Which components should you check? Let's take a closer look.

Start by cleaning the filter element.

If you notice error F03 on your Hisense washing machine display, don’t rush to call a technician. This error code indicates problems with the drain, most often caused by a simple blockage. So, first try cleaning the drain hose and the waste filter of the washing machine.

It's important to remember safety precautions. Before beginning repairs, unplug the machine and turn off the shut-off valve. Now you can begin cleaning the drain hose.

Disconnect the drain hose from the drain connection and the washing machine body. Rinse it under warm running water. It's likely that some dirt will start to come out of the hose. This is understandable, as liters of waste liquid flow through the drain hose with each wash.

The next item to check is the drain filter. It collects water from the tank and passes it into the pump. It traps large debris, hair, threads, and other foreign objects that may have gotten into the machine. The "dustbin" is located at the bottom, front of the washing machine.

To clean the debris filter:

• prepare a shallow container;
• cover the floor around the machine with dry rags;
• open the technical hatch door (pry it with a screwdriver);
• Tilt the body back slightly and place a container under the washing machine to collect water (in the location of the debris filter);
• unscrew the "trash can" half a turn;
• wait until some of the water drains into the basin;
• Remove the drain filter completely.

Now the dustbin needs to be cleaned of any deposits and dirt. Large debris can be removed by hand, and limescale can be washed off with a sponge. If the deposits are particularly thick, you'll need to soak the filter in a citric acid solution for a couple of hours.

Do not wash the drain filter in hot water as the element may become deformed.

It's also essential to clean the filter seat. Use a rag to remove any accumulated dirt from the walls of the hole. Shine a flashlight into the "nest" and remove any debris that's deeper.

Once finished, screw the drain filter back into place. It's important to position the part evenly to prevent leaks. Now you can run a test cycle. If the F03 error code no longer appears, then the cause was indeed a simple blockage.

It makes sense to check the pump

If the drain doesn't work after cleaning the drain hose and filter, further diagnostics will be necessary. The cause may be a malfunctioning pump. The pump is responsible for pumping water from the tank to the sewer.

The first thing to check is whether the impeller is jammed. It spins and directs the pumped liquid. Sometimes its blades become blocked by foreign objects (coins, hairpins), or by tangled hair.

Unscrew the drain filter again and shine a light into the resulting hole. Clean all debris from the impeller. Try spinning the blades. If movement is difficult, it may be damaged.

Next, perform an "electronic diagnostic" of the drainage system. Plug in the machine and run the "Spin" cycle. Listen to the washing machine. If the motor hums and the impeller remains static, the pump is broken.

Repairing the pump isn't practical. It's easier and more reliable to buy a new pump and install it in its place. Components for washing machines Hisense can be easily ordered from online suppliers or found in large hardware stores. The main thing is to know the serial number and model of the washing machine.

How to remove a broken pump:

• disconnect the machine from communications;
• Place the machine on its left side (be sure to place it on the side where the powder compartment is located);
• remove the washing machine tray;
• find the pump;
• disconnect the wiring and pipes from the pump (it is better to take a photo of the connection diagram first);
• unscrew the bolts securing the pump;
• remove the pump.

Be sure to remove any dirt from the mounting surface. The pump housing should also be cleaned. Installing the new pump is done in reverse order.

First, the pump is placed in its designated location and secured with fasteners. Next, the wires and hoses are connected to the element. Afterwards, the tray is screwed in place, the machine is returned to its original position, and the utility lines are connected.

Now the test cycle starts again, and you can select the short "Rinse + Spin" mode. If error F03 recurs, you'll need to contact a service center. The semiconductors on the control board responsible for draining may be damaged. Repairing the washing machine's electronic module yourself without the knowledge and experience is risky.
