Currently, washing units purchased in retail stores of household appliances have a specialized notification system for errors that have occurred during operation. They identify emerging faults and show information on the display error codes washing machine Ariston. This, in turn, provides the user and the technician with convenience in troubleshooting and finding their remedy. This system program is provided in the products of INDESIT COMPANY, before the renaming this company was named MERLONI Elettdomestici. The most popular models of washing machines from this company are named Indesit and Ariston.

How to decipher errors in typewriters with the EVO-II system without a display

Inexpensive devices manufactured under the Indesit and Ariston brands lack a display as such. Even in such cases, errors are displayed on these models by backlighting and displaying many combinations of LEDs, each value displays only 1 error. They are assigned the data to the value:

the timer is assigned the value KH1;
super wash 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 can 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.

Only displayed KN4 - this symbolizes the occurrence of an error number F01... It is displayed when the wiring system is short-circuited in the section of the circuit that leads to the control of the washing machine motor. 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.

Illuminated KN3which indicates an error F02, it tells you that there is no signal about the rotation of the electric motor on the controller. In order to solve this problem, you must:

first of all, make sure that the rotor does not jam, which can be caused by seizure of the bearings on the drum.
Make sure that the connection of the controller and the motor is correct and complete.
Using a multimeter, measure the generator winding, in working order it should give out in the region from 115 to 170 Ohm (the readings differ due to the various applicable contrailers).
In the event of faults, replace the faulty parts.

Display on the dashboard KN3 and KN4 signals an error F03, namely that the heating element is sticking, or the temperature sensor is out of order.The first step is to make sure the integrity of the connection between the sensor and the controller. If, nevertheless, the correct connection is necessary to measure the resistance, it should be about 20 ohms.

In the case when the display only lights up KN2, then this signals an error F04, which in turn indicates a 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 to make sure that it is working. If the malfunction cannot be eliminated, then it is necessary to consistently replace the above-mentioned parts.

Backlight KH2 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 must:

Make sure the correct connection and integrity of the wires going from the pump to the controller;
Make sure the flow of electricity to the drain pump when it is supposed to be activated;
After disconnecting the washing machine from the mains, supply 220 V to the pump, after which you will make sure that it works;
Check the health of the sensor responsible for determining the water level, and make sure the integrity of its connection with the controller;
It is necessary to make sure that the filter and the drain hose are clogged, if clogging is confirmed, clean it.

Is burning KN2 and KN3, this indicates an error F06which indicate a problem with the buttons. The first step is to make sure of the contact between the dashboard and the command device, and then make sure that the buttons work. If the error has not disappeared, then a phased replacement of the dashboard and command unit is performed.

Flashing KN2, KN3 and KN4 signals about an error F07, which informs that the heating element of the machine (TEN) does not heat the water. As in all the above cases, make sure the integrity of the connection of the above elements, then check whether the water in the machine heats up. If no faults with the wires are detected, replace the heating element.

When your display shows KN1, this indicates an error F08 - this is the sticking of the heating element relay when starting up in the washing machine tank, there was a failure in the operation of the sensor responsible for determining the water level. It is necessary to check the element and the heating relay one by one, if a malfunction was detected in one of the above parts, it needs to be replaced.

KN1 and KN4 display an error F09, which tells you about a memory failure of the device. 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 wiring going to it. If the wiring and sensor are in good order, it is necessary to replace the controller.

Error F11 displayed on the dashboard as lit indicators KN1, KN3 and KN4. The error is caused by a lack of power in the pump, it 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 Ohm, in case of non-compliance with this value, it will be necessary to replace the pump with a similar new unit.

KN1 and KN2 indicate an error F12 displays 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 indicates a malfunction in the control circuit that is responsible for the drying operation. The first step is to make sure that the temperature sensor is properly connected to the controller.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 system elements.

KN1, KN2, KN3 and KN4 - F15 - also indicates a problem with the drying process. This error indicates a malfunction of the heating element, only a complete replacement of this element will help here.

All indicators are off - F16 - the 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 voltage supply to the door lock of the machine is stopped. It is necessary to carry out 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 system microswitch with the door closed. If necessary, replace the above elements.

LED4 and KN3 - F18 - the error indicates a malfunction in the connection of the processor, which 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 malfunction, replace these elements.
