The Ariston washing machine stopped during washing, the sensors flash and the error F8 (F08) lights up on the display. This can happen at system startup, in the middle of a cycle, before or after rinsing. What to do? What does F8 (F08) mean in an Ariston washing machine? How to fix the problem yourself? You will find answers to all these questions in this article.
Error decoding
By the code F8 (F08), the manufacturer has encrypted a heating error. This may indicate a malfunction of the heating element or damage to the temperature sensor and other problems.
With this error, the alphanumeric code symbol F8 (F08) is displayed. If the washing machine is without a display, the button indicators will blink. The signal sequence will vary, depending on the model:
- on Ariston Margherita machines, the hatch lock lamp will start to light continuously, with a small pause a series of 8 lights will be repeated.
- lineup AVL, AVSL will report a malfunction by flashing the delay timer and hatch lock indicator (key).
- on models of the ARSL, ARXL series, a series of program indicators will turn on fully, the spin lamp will light continuously.
- for Hotpoint-Ariston Aqualtis machines, the “500” lamp will light.

Problems not requiring repair
TEN contacts were sent
The cause of the problem may be poor electrical contact. Three wires are connected to the heating element, each of them is connected to the heater connector. If at least one of the contacts is weak, loose or falls off, this will cause a machine failure.
To eliminate this malfunction, first of all, disconnect the power cable from the mains. Then remove the rear panel of the machine, behind which the TENA contact terminals are located and carefully adjust the departed connector. After that, put the removed cover back in place and check the operation of the unit.
Control board failure
To restore normal operation, sometimes it is enough to reboot the control system. It is necessary for some time (5-10 minutes) to remove the plug from the outlet. If the cause of the malfunction is the failure of the control module, then after restarting, normal operation will resume.
High humidity in the room
Installation of the washing machine in rooms with high humidity negatively affects many of its elements. Traces of corrosion may appear on the case, and condensation formed on the electrical contacts will lead to errors in operation.
To avoid such malfunctions, the machine should be installed in a dry, ventilated area with proper ventilation. In the bathroom, as a rule, a high moisture content and a greater likelihood of a malfunction. Therefore, it is better to install the unit in other rooms, for example, in the kitchen or in the pantry.
Malfunctions in the heating circuit
Faulty TEN
Problems in the heating element are a common cause of error F8 (F08). Under the influence of water and washing powder, solid deposits appear on the heater. Trying to warm the scum layer, the heating element is exposed to high currents and burns out. The failure of the heating element a power surge in the electric network can also serve.
If the error F8 (F08) appeared during the operation of the washing machine, then you can determine the malfunction by placing your palm on the hatch of the loading compartment. Water with a temperature above 40 degrees will heat the glass.
In order to prevent the formation of scale, it is recommended that cleaning the machine with citric acid. Removing solid deposits will help increase the life of the heater and prevent its overheating. To do this, about half a glass of citric acid is poured into an empty drum and the spin mode is activated. After completing the washing cycle, the scale together with water will go into the drain.
The thermostat has broken (temperature sensor)
The thermostat is used to adjust and maintain the set temperature. Sensor failure is determined by the following criteria:
- Despite the temperature set by the mode, the water is heated to a boiling state.
- the temperature of the walls of the housing of the unit rises.
One of three thermostat varieties, different in design, but performing one function, is installed on washing machines:
- bimetallic
- thermistor
- gas filled
To determine the status of the thermostat, it must be removed and check the resistance on the contacts with a multimeter. This will require opening the machine body, and each of the three types of sensor has its own mounting characteristics, this must be taken into account.
A faulty thermostat cannot be repaired; it must be replaced with a new one. The operation of the washing machine with a broken temperature sensor will lead to the burning of the heating element, so this repair should not be delayed.
Faulty line filter, wiring or contacts
The interference filter is out of order
To protect electronic systems, a noise filter is installed in the washing machine. With severe voltage drops, this part may fail. If a breakdown occurs, you will have to look for a new protection device. Interference filter malfunction detected by checking with a multimeter and external inspection. If burnt contacts are found or a burning smell is present, the cause of the error is clear and replacement is required.
Damaged wiring or contacts
A common cause of a malfunction is a problem with the wiring of the washing machine. The contacts of the heater and electrical circuits are oxidized by moisture. Damage to the internal wiring leads to a short circuit and breakdown on the machine body.
A thorough inspection of all wires and connections will help determine the problem. If a section with damaged insulation is detected, it must be repaired using electrical tape or heat shrinkage. Burned contacts should be cleaned, and badly damaged ones should be replaced.
The water level sensor has broken
This sensor (pressure switch) controls the set of water, its level in the machine and is responsible for draining the liquid. The failure of the level sensor is determined by the following signs:
- lack or excess of water when filling the machine.
- a complete lack of water during the washing process.
- continuous set of water with subsequent discharge.
- skipping machine rinse.
To check the health of the sensor, it is necessary to turn off the power by removing the rear panel of the machine body and disconnecting all pressostat mounts. After that, remove it and check the contacts with a multimeter. You should also make sure that there are no blockages in the sensor tube.
Malfunctioning pressure switch will require replacement, the installation procedure for a new device will be the reverse of removal.
Bad control board
The control board is responsible for the operation of all electronic systems of the washing machine, engine, heating element, etc. The main causes of breakdown of the control module:
- voltage drops in the network and, as a result, circuit of the electronic components of the board.
- disconnecting the machine from the network without first pressing the shutdown button.
- exposure to high humidity in the room.
First of all, you should inspect the module. To do this, remove the control panel with buttons, press the holding latches and disconnect all electrical connectors. Control Board Repair, in case of its malfunction, is to find and replace damaged parts. This requires certain skills and abilities to handle a soldering iron.
The control board is a very expensive device, therefore, work on its repair should be carried out by a qualified craftsman.
