Currently, washing units purchased in retail stores for household appliances have a specialized warning system for errors that have occurred during operation. They identify emerging faults and show information on the display. Ariston washing machine error codes. Which in turn provides the user and the master with convenience in troubleshooting and finding their method of elimination. This system program is provided in the products of INDESIT COMPANY, before the renaming, this company had the name MERLONI Elettdomestici. The most popular models of washing machines from this company are named after Indesit and Ariston.
How to decipher errors in cars with the EVO-II system without a display
In low-cost devices manufactured under the Indesit and Ariston brands, there is no display as such. Already in such cases, on these models, errors are displayed by highlighting and displaying many combinations of LEDs, each value displays only 1 error. They are assigned data to a value:
- the timer is assigned the value KH1;
- superwash is responsible for KH2;
- quick wash indicates KH3;
- an indicator indicating KH4 is attached to the quick wash button;
- the indicator responsible for spinning the laundry indicates LED 4.
Due to the fact that some of them are lit and some are not, you will be able to fix the error that has occurred.
In the design of devices that have displays, it is much easier to understand the error number. They are displayed on them in the form of a code consisting of Latin letters and numbers.

List of EVO-II errors and their interpretation
Displayed only KH4 — this symbolizes the occurrence of an error number F01. It is displayed when there is a short circuit in the wiring system in the section of the circuit that leads to the engine control of the washing machine. First, before proceeding with the repair, it is necessary to completely check the device for the presence of water on the contacts of the controller fields, which are connected to the drive motor of the machine using a harness. If, after carrying out this manipulation, the error remains, it is necessary to check with a multimeter what exactly is out of order and replace it.
Highlighted KN3which indicates an error F02, it tells you that there is no signal about the rotation of the electric motor on the command device. In order to solve this problem you need:
- first of all, make sure that the rotor is not seizing, which can be caused by seized bearings on the drum.
- Make sure that the connection of the command device and the motor is correct and intact.
- Using a multimeter, measure the winding of the generator; in working condition, it should give out in the region from 115 to 170 ohms (readings vary due to the applicable different contrailers).
- In case of malfunctions, replace defective parts.
Display on the dashboard KN3 and KN4 signaling an error F03, namely that the heating element has stuck, or the temperature sensor has failed. The first step is to make sure that the connection between the sensor and the controller is intact. If, however, the correct connection is necessary to measure the resistance, it should be about 20 ohms.
When the display only shows KH2then it indicates the presence of an error F04, which in turn indicates the failure of the water sensor. In order to eliminate this malfunction, the first step is to check the integrity of the wires going from the controller to the sensor, and also make sure that it is working. In the event that the malfunction could not be eliminated, then it is necessary to sequentially replace the above parts.
Backlight KN2 and KN4 tells us about the error F05, which is associated with a malfunction of the drain pump or water level sensor. In order to fix this problem you need to:
- Make sure that the connection and integrity of the wires coming from the pump to the controller are correct;
- Make sure that electricity is supplied to the drain pump when it is supposed to be activated;
- Having disconnected the washing machine from the mains, apply 220 V to the pump, after which it will make sure that it is working;
- Check the health of the sensor responsible for determining the water level, and make sure that its connection with the controller is intact;
- It is necessary to make sure that there are blockages in the filter and the drain hose, if blockage is confirmed, clean it.
Lit KN2 and KN3this means an error F06, which indicate a problem with the buttons. First of all, you need to make sure that there is contact between the dashboard and the command device, and then make sure that the buttons are working. If the error has not disappeared, then a phased replacement of the dashboard and command device is carried out.
Flashing KN2, KN3 and KN4 signals an error F07, which reports that the heating element of the machine (heater) does not heat the water. As in all the cases described above, make sure the integrity of the connection of the above elements, and then check whether the water is heating up in the machine. If there are no faults with the wires, replace the heating element.
When the display shows KN1this indicates an error F08 — this is a sticking of the heating element relay when starting up in the tank of the washing machine, a malfunction occurred in the operation of the sensor responsible for determining the water level. It is necessary to check the element and the heating relay in turn, if a malfunction of one of the above parts has been detected, it needs to be replaced.
KN1 and KN4 display an error F09, which tells you about a device memory failure. In order to eliminate this error, it is necessary to flash or replace the chip.
KN1 and KN3 responsible for displaying the error F10, namely the lack of contact with the water level sensor. Before replacing a part, it is necessary to check the integrity of the electrical wiring going to it. If the wiring and the sensor are OK, it is necessary to replace the controller.
Error F11 displayed on the dashboard as illuminated indicators KN1, KN3 and KN4. The error is caused by a lack of power in the pump, this could be caused by a broken wire. Checking the pump for performance must be done with a multimeter. To do this, apply the probes to the pump and monitor the resistance on the device screen. The working device should give a result in the region of 200 ohms, in case of discrepancy with this value, it will be necessary to replace the pump with a similar new unit.
KN1 and KN2 indicate an error F12 indicates a problem in the signal path from the controller to the display module. In the event of a breakdown, as in all cases, we check the integrity of the wiring, and then we make a phased replacement.
KH1, KH2 and KH4 — F13 — this error marks a malfunction in the control circuit that is responsible for the operation of drying clothes. The first step is to make sure that the connection between the temperature sensor and the controller is correct. If everything is in order with the contacts, it is necessary to check the integrity of the above elements, and replace them if necessary.
KH1, KH2, KH3 and KH4 — F14 – lights up when the drying process does not want to start. First of all, it is worth checking the connections of the heating element, which is responsible for the above process with the main controller of the machine. If necessary, replace one of the elements of the system.
KN1, KN2, KN3 and KN4 — F15 — also indicates problems with the process of drying clothes. This error indicates a malfunction of the heating element, only a complete replacement of this element will help here.
All indicators are off — F16 — an error indicates a malfunction of the washing drum. However, such errors often occur with models that have a vertical load of laundry.
LED4 and KH4 — F17 — the error indicates a malfunction with the drum door, there are two options for the development of events — the first option is that the lid may not be tightly closed. And the second option implies that the power supply to the door lock of the machine has been cut off. It is necessary to take the following measures: first of all, check the integrity of the contact fields that connect the controller and the lock on the machine door, also check the circuit for voltage. Check the integrity of the microswitch of the system with the door closed. If necessary, replace the above elements.
LED4 and KH3 — F18 — the error marks a malfunction in the connection of the processor that controls the electric motor of the machine with the controller. It is also necessary to check the integrity of the contact fields; in case of a malfunction, replace these elements.
In this article, we have explained the main Ariston washing machine error codes, taught you how to identify them correctly and instilled basic methods for their elimination. However, remember that any repair must be approached with a cool head, if you are not confident in your skills or abilities, we recommend that you turn to professionals.
