When error F08 occurs on an Ariston washing machine, many people do not know what to do. Most people have never encountered it before. This code occurs in both old and new models. Because any mechanism tends to fail. If the washing machine has a complex system, then the malfunction must be approached carefully and responsibly. It’s good that Ariston washing machine manufacturers thought of creating a set of codes that have self-diagnosis. This helps make a person's life much easier.
Error F08 on washing machines without a screen
Some old and new models of Ariston washing machines are produced without a display. This helps save on equipment costs, but can also be inconvenient in finding problems. If there is no screen on the Ariston washing machine, then you can find the error only with the help of flashing and burning lights.
They indicate the washing mode, water temperature and more. At first glance, it may seem difficult to calculate error F08 without a display. But it turns out that on the Ariston washing machine all the indicators have special numbers. Therefore, finding the F08 error becomes much easier.
What does error F08 mean?
What does error F08 mean, many people do not know. When you put in the laundry, set the desired mode and the Ariston machine started washing, after a while error code F08 may appear. Most often, the code is displayed ten seconds after the program starts. It can also occur at any time during the wash itself. It happens that the Ariston washing machine did not rinse, the liquid is pumped out and stops, and code F08 appears on the display, and spinning may also not start.
Error F08 indicates that the heating element of the Ariston machine has broken down. This could be a breakdown of the heating element, temperature sensor or control board. Most often there is a problem in the heating circuit; it may break or be damaged, and there may also be a breakdown in the pressure switch. It happens that error code F08 is due to high humidity that is present where the machine is located.
Possible faults
Let's analyze the breakdowns with error F08 according to the frequency of their occurrence.
Faulty heating element - from 1500 rubles*
The tubular electric heater is an important part of the washing machine. It heats the water to the desired temperature at the beginning of the wash and then maintains it throughout the process. Without it, SMA Ariston can only wash in programs without heating in cold water.
The reason for the failure of the heating element with error F08 is a breakdown in the housing. The code most often lights up during washing, but can also appear at other times: when turned on, during rinsing or spinning.
Failure of the heating element is the most common malfunction with error F08.
HOW TO FIX
The heating element is not repaired, but replaced with a new one.
The control unit is broken - from 2100 rubles*
The control module is the “brain” of the washing machine and the command center. If it breaks down, error F8 appears if the heating element relay on the control board is stuck in the on state, or if the radio components in the heater circuit are burned out. Usually these are resistors or capacitors, but there may be others. Therefore, you need to check the entire circuit of the heating element on the board. Sometimes the module firmware fails.
Error F 08 due to problems with the board appears when turning on, during the transition to rinsing or spinning. The machine stops and aborts the program with an error.
HOW TO FIX
Repair depends on the type of control unit failure. You need to check the board and determine what is faulty. Then:
The pressure switch has failed - from RUB 1,700*
Although the level sensor is not directly connected to the heating element, its incorrect readings can cause error F 08. This happens when the sensor is stuck in the “empty tank” position or transmits signals to the control module about an empty and full tank at the same time.
Typically, an Ariston machine displays error F08 due to an incorrectly working pressure switch immediately after starting the program. But the first time the sensor fails, the code can come on at any stage of program execution.
HOW TO FIX
Repair depends on the reason why the pressure switch is not working correctly. The sensor can give a signal about an empty tank if the pressure switch hose has come off or is worn out due to vibrations. In this case, you need to return the hose to its place or replace it if it is damaged. In other cases, the sensor itself is faulty and needs to be replaced.
Damaged wiring or contacts in the heating element or pressure switch circuit - from 1600 rubles*
A break in the heater or level sensor circuit may occur due to the fault of the wiring or contacts. These are the weak points of washing machines for several reasons:
Contacts come off, oxidize or burn. Wires fray, burn out, or are chewed by mice. As a result, a break occurs and the module loses connection with the heating element or pressure switch. That's why the machine writes error F8.

Troubleshooting
Many people don’t know how to fix error F08 on their own. You must first find the reason. You can try rebooting your Ariston washing machine several times.
But, if you were unable to resolve error F08, you need to try other methods. When error F08 appears, first of all you need to unplug the device from the outlet and move it to a free place. This is necessary so that it is possible to get to the washing machine from all sides. Next you need to remove the cover that is located on the back of the Ariston washing machine and unscrew all the screws. We remove the wires going to the temperature sensor and heating element.
You need to take a multimeter and check their condition; if the indicator is one or zero, you need to replace it. If, when ringing, no sticking of the sensor, current leakage or open circuit was found, then you need to conduct a visual inspection of the wiring. Only if nothing is noticeable outwardly, you need to check it with a multimeter. If no faults were found, then perhaps the problem lies in the modular control of the Ariston device or the pressure switch.
If, however, a breakdown was not detected, as a result of which error F08 appeared, then most likely the cause of the problem is in the electronic module. Repairing Ariston washing equipment may not be as expensive as it seems.
But, if you start eliminating the cause of error F08 yourself, you can only make the situation worse. After all, the modular control of an Ariston car is difficult to repair; you need to have a good understanding of electronics. You need to leave such thoughts if you have no experience in this. The best option would be to trust a professional technician who can fix the malfunction in the electronic module and error F08.
There may also be a malfunction in the Ariston washing machine. What to do if error code F08 appears for the first time? You need to remove the wire from the electricity and after fifteen minutes turn on the washing machine. A reboot will occur and the problem should go away.
The cause of error F08 may be dampness and humidity. When there is an increased level of moisture in the room where the Ariston washing machine is located, it can get on the electronic module. It is necessary to remove the board and inspect it for the presence of fungus and dampness. If anything is found, it needs to be cleaned, dried and put back in place.
To avoid this problem, you just need to place the Ariston washing machine in a place where there is no high humidity. Because modular control can completely fail. But to purchase a new electronic module, you need a lot of money.
It is important to remember that the cause of error F08 may be loose contacts. To do this, you need to check all connections of the heating element and temperature sensor. This often happens if an Ariston washing machine was transported.
Causes that are easy to fix on your own
If a failure occurs, the owner can check the operation of the main systems. If the cause of the problem is high humidity in the room or a random error in the operating algorithm, then after drying the electronics or resetting the settings in the memory of the control unit, the defect disappears.
The table lists the main reasons and indicates the complexity of the repair process.
| Problem | Labor intensity of inspection and repair time |
| Increasing indoor humidity | Medium, requires partial disassembly (30 minutes to 1 hour) |
| Software failure in the controller | Small, requires temporary power outage (10-20 minutes) |
| Broken contact in the power circuit | High, requires partial disassembly with cleaning of plugs or restoration of insulation (from 30 minutes to 2 hours) |
High humidity
Since the machine is located in the bathroom, when the air humidity is high, condensation penetrates into the internal volume of the case and settles on the electronic components.
Water forms paths that conduct electrical current, causing electronics to malfunction.
To carry out repairs, turn off the power and get to the controller. Traces of moisture are removed with an alcohol wipe and then dried with a construction or household hairdryer. To prevent the problem, it is necessary to ventilate the room (for example, by installing a forced hood).
Departed contact
Loss of contact occurs after transportation and movement of equipment, as well as due to exposure to vibration or high humidity. It is necessary to turn off the power, and then partially disassemble the housing and sequentially check the connections of the electrical wiring harnesses. Foreign deposits on the contacts or damage to the insulation are not allowed. It is recommended to treat the pads with liquid to protect them from moisture.
Control module failure
When a problem is first detected, to restore normal operation of the electronics, you must remove the plug from the outlet for 10-15 minutes.
The controller is reset and the operating cycle must be restarted after power is applied.
If the malfunction occurs again, then it will be necessary to check the ACS components and replace worn components. To dismantle and install new elements, special soldering equipment is required. It is recommended to carry out work in a specialized service.
Repair of heating element and temperature sensor
Error F08 also indicates a breakdown of the heating element, and it needs to be completely replaced. Repairs can be done either with your own hands or by calling a specialist. Elimination of the breakdown that caused the error F08 to appear is carried out in several stages.
First, you need to unplug the Ariston washing machine from the outlet and go to the back. To get to the heating element, you need to pull out the plug; it is located at the bottom. The heating element will be located in the right corner. Next, to eliminate error F08, all wires are disconnected, but do not forget that after replacing the heating element, you need to connect everything back.
In order to prevent mistakes, you should take a photograph of how the wires were located or draw a diagram. Then unscrew the nut, it is located in the middle of the heating element, and press it inward. Now you should remove the heating element of the Ariston machine and then replace it with a new one. You need to place it in a special hole, no tilting should be allowed, it must stand tightly.
It is necessary to fix the heating element and tighten the nut. You need to secure it well, but you also shouldn’t forget that if you overdo it, you can simply squeeze it out. After this, put all the wires in place according to the diagram that was photographed. Then a test wash is carried out, you can run it up to 60 degrees.
It is also important to check the functionality of the temperature sensor of the Ariston washing machine. It is necessary to completely unplug the device from the outlet. Next, we disassemble the washing machine; you need to open the lid, which is located on the inside. Disconnect all the wires where the sensor is located and loosen the screw part holding the heating element. Remove the sensor and check the resistance with a multimeter. If the temperature element does not work, then you need to replace it with a new one, since repairs will not help in this situation.
Prevention
To avoid breakdowns, prevention must be carried out. This will help extend the life of your Ariston washing machine. In order to avoid scale on the heating element and the appearance of error F08, you need to add a special powder before washing. Before putting clothes in the wash, you should check all pockets for items. Do not reload the drum; this may cause damage.
It is not recommended to set the wash to 90 degrees, as this can damage the heating element. When the Ariston washing machine is working, you should not leave it unattended; if a short circuit or leak suddenly occurs, the person will not be able to take emergency action.
If you take preventive measures, this will help avoid various breakdowns, and the service life of your Ariston washing machine will increase. But if it happens that the washing machine displays error F08, you need to try to fix it yourself.
Preventive actions
To increase the life of the heating element, it is necessary to add a special preparation along with the powder that reduces water hardness and prevents the formation of salt deposits. The increased temperature of the liquid during washing (from 80°C) also negatively affects the operating time of the heating system. You should not constantly set the maximum parameters.
