Indesit wisl 85 error codes

How to determine the error code of a washing machine without a display

If after starting the program the indication began to flash, it indicates a malfunction of the technique. The problem can occur at any stage: spin, rinse or drying. In order to understand exactly what kind of problem the signals indicate, you need to decipher them.

Sensor placement depends on the series. Look at the LED’s, check the table and find out the specific error code.

IWSB, IWUB, IWDC, IWSC series indicators

Here the LEDs above the mode buttons and the auto-lock switch are responsible for visualizing errors. Power key indicator will blink in any case if there is a problem.

The error indicators in this series are the LEDs of the additional functionality (indicators 1-4) and the spin button (indicator 5). In the event of any malfunction, the lock button will blink red heavily.

W, WS, WT, WI series

One of the oldest generations of washing machines is equipped with only two LEDs. lock the hatch and turn on the device. Blinking at intervals of 3-5 seconds indicates an error, and the number of flickers. its code. The hatch lock LED, as a rule, just lights up green or red.

It should be specified that not every failure of the washing machine is visualized in this way. If the problem is in electronic circuits or with blown elements, the main panel may not light up at all.

Error codes of Ariston and Indesit washing machines with EVO-II control system

As you know, most modern washing machines have a diagnostic system that captures failures that occurred during operation, and displays them in the form of error codes on the control panel. In addition, this system allows you to perform autotest programs, with which you can check the operability of the CM in various modes. The diagnostic system facilitates the search and elimination of possible CM defects that arise during the operation of these machines.

This system is also available in modern washing machines with electronic control systems of INDESIT COMPANY (formerly known as MERLONI).

In all lines of this company’s SMs with the obsolete EVO-I control system, error codes were determined by the number of flashes of the LED indicator (in series). For example, if the light flashes 5 times at short intervals, and after a pause the cycle of flashes repeats, it corresponds to error code F05. Deciphering the error code is no longer difficult, for example for F05 it is a problem with the water drain (pump, clogging in the drainage circuit, pressostat).

Usually, when an error occurs in these SMs, the knob of the command device starts turning and the execution of the current washing program is stopped. You can find a detailed description of EVO-I control modules in another article.

In an EVO-II based SM, everything is a bit more complicated. As these machines have different functions and design (for example, different control panels), on some budgetary SM (without display, for example in AVL series models, etc.) we’ll use only one control panel.) many repairmen have trouble with the order of reading the fault codes. Codes are calculated on the basis of certain LED light combinations. The easiest way to read the error codes is on the models with display (e.g. machines of AVD line, etc.).). They are displayed directly on the indicator.

Error codes on INDESIT and ARISTON EVO-I/II models can also be read with a special diagnostic key (SAT), which is connected to the service socket on the SMD. The key also allows you to test the SM in different modes: both offline and under the control of an external personal computer.

Let’s take a closer look at the process of reading out error codes in INDESIT, ARISTON EVO-II series automatic water heaters without using a diagnostic key.

Fault codes and how to read them

As noted above, in EVO-II display type (AVD range) CMs, error codes are shown on the LCD display 1

Fig. 1 SM EVO front panel with display (AVD line)

In Fig. 2 Here is the front panel of the AVL range SM.

In this case, the error codes are indicated by the CLEANING indicator (LED 4) and the LIGHTING of the SCHEDULE TIMER (KN 1), SUPER WASH (KN 2), SPEED WASH (KN 3) and RINSE RINSE (KN 4) buttons.

Actually, the “secret” of detecting error codes on EVO-II SM control panels with LED indication is quite simple. Each indicator is a digit of an error code in binary notation. The very process of calculating the error code number is to match specific indicators to specific digits of the binary code and translate that code into decimal notation.

In our case. LED 4 corresponds to the first digit of the binary code, KN 3 to the second, KN 2 to the third, KN 1 to the fourth and LED 4 to the fifth.

If you go back to error code F05 as an example, the digit 5 in the binary code will look like: 00101 (5 digits, indicators KN 2 and KN 4 are lit).

Yet, in order not to bore our readers with converting numbers from one number system to another, here is a universal table (see table below). 1) To determine the error codes.

In spite of the fact that the combination of indicators (buttons with indicators) here is different, the error codes are read as in the previous case, the designations of indicators (KN 1. KN 4, LED 4) are the same.

And now let’s dwell on the error codes given in the table. 1, that is, let’s find the causes of troubles and ways to eliminate them (of the washing machine). Basically all this information is summarized in Tab. 3.

Table 3 Description of error codes SM EVO-II (AVD and AVL series)

Fault codes Possible causes of malfunction and remedies Note
F01 Short-circuit (triac) in the supply line of the drive motor Check possible water leakage on the J9 connector pins Check the terminal strip on the drive motor (possible cause of the problem). chemical corrosion of its contacts). Replace electronic module 90% of this malfunction is caused by a defective drive motor. If motor does not malfunction. see. left column. The EEPROM nonvolatile memory firmware has absolutely nothing to do with
F02 Drive motor is not running, tachogenerator circuit is short-circuited or interrupted. Check if pins J9 of electronic module connector are firmly connected. Check the resistance of the tacho sensor (about 115. 170 0м). The resistance is measured between pins 1 and 2 of connector J9. If a short circuit in this circuit, disconnect J9 connector and check the wires on the TAKHSTATOR side. If an asynchronous drive motor is installed in the SM, make sure that pins 6 and 7 of connector J9 are electrically connected to the sensor. Replace motor Replace electronic module If the tachometer is shorted, there could be foam on the sensor or loose connections on the tachometer strip. If the sensor is shorted. Look for burned out traces on the electronic module and 2 or 3 burned out resistors. The EEPROM firmware has absolutely nothing to do with it
F03 The NTC temperature sensor circuit is shorted or open, or the heating element relay is stuck Check the contact reliability of J8 connector. Check the temperature sensor, given that its resistance at room temperature (20 ° C) is 20 kOhm (you can measure on pins 11 and 12 of connector J8). If the result is different, check the integrity of the wiring from the module to the sensor. Replace NTC temperature sensor. Replace electronic module If the actions in the left column do not find the faulty element, re-flash the contents of the non-volatile EEPROM
F04 Level sensor generates signals Empty Pot and Overflow simultaneously The reason for this defect is that the contact group “Empty Pot” in the sensor is “stuck”, in this case the SM pours the water up to the overflow level. Once this water level is reached, the drain pump automatically turns on. Check the quality of the connections of J3 connector on the electronic module. Check the condition of the level sensor (on the contacts of the connector and):. contacts-2-4 closed. the “empty tank” level;. pins 2-3 closed. “FULL BACK” level;. contacts 2-1 closed. level of “overflow” (not less than half of the glass of the loading hatch. Replace the level sensor. Replace electronic module The EEPROM firmware has absolutely nothing to do with it
F05 Drain pump is blocked (doesn’t work) or level sensor generates Empty tank signal after completion of water drainage procedure. Check reliability of connections in J9 connector. At the moment when the pump is supposed to work, you can check whether there is 220 V AC voltage between pins 8,9 of connector J9. Check filter and drain hose. Replace Drain Pump. Not used in AVD and AVL series This problem is most often caused by foreign objects in the pump. Drain pump function can be checked by connecting it to AC 220V. It has nothing to do with the EEPROM firmware
F06 Not used in AVD and AVL series.
F07 After the water fill operation, the level sensor does not clear the Empty tank signal If there is no water in the tank after the water fill operation, there is no power to the heater. This is a safety feature because without water the FET can burn out. Possible causes:. there is no water in the water supply or the water pressure is too low;. Water priming valve is defective;. blockage in the water inlet line;. Level sensor defective. After water filling (if any) the contact group Empty tank of the level sensor must be open. Its state is monitored, for example, on pins 2 and 3 of connector J3 of the electronic module. Otherwise replace level sensor and electronic module in series The EEPROM firmware has absolutely nothing to do with it
F08 The “electric heater relay” on the module was constantly turned on (“stuck” contact set) or level sensor generates simultaneously signals Empty and FULL tank Check the level sensor. see. F04 error. Heating element control relay on the module must be checked by replacing. Check wiring from L socket to level sensor. Check the connection between the heating element and the module. Pin 5 and 6 of connector ^3). Check if the heating element is working correctly. Change level sensor. Replace the electronic module Firmware of non-volatile memory EEPROM has absolutely nothing to do with it
F09 Error (failure) of the EEPROM content, SETUP SM In many modules the EEPROM chip is soldered on the module’s board. The best option is to install the chip on the transition block. In this case, the chip is easily removed and installed without soldering, when installing it on the module, pay attention to the coincidence of the setting keys (on the board and on the chip). If the EEPROM is intact, the whole module should be replaced (remember that the memory chip installed on the module has firmware specific for the particular SM model) Re-flash the content of the non-volatile EEPROM. Of course, you need a programmer and an appropriate firmware file. Before flashing the memory chip it is necessary to read its contents and save it as a separate file so that you can always restore the original firmware
F10 After the filling process has started (within the allotted time) the level sensor does not generate the FULL BATCH signal (assuming that the Empty BATCH signal is passive, i.e. there is already water in the tank). Check the level sensor. See. F04 error. Check the electrical connection between the plug J3 in the electronic module and the level sensor. Replace level sensor. Replace electronic module Most often this error can be caused by low water pressure when filling the tank (the filler neck may be clogged, the filler valve may be malfunctioning, etc.).). The firmware of the non-volatile memory EEPROM has nothing to do with it
F11 There is no feedback signal from the drain pump (the pump power supply circuit is broken or the pump winding is broken). Check reliability of connection of drain pump with electronic module. Check the resistance of the drain pump winding on connector J15, pins 1 and 2 (in case the machine is equipped with the Easy Door function) or on connector J9, pins 8 and 9. Resistance of the drain pump winding should be about 170 Ohm. Replace drain pump. Replace electronic module EEPROM firmware has absolutely nothing to do with it
F12 No communication between display module and electronic module. Check reliability of electric connections between the connector J11 of the main electronic module and the display module. Replace the main electronic module. Replace display module In that case you have very little choice: either the indicating module or the basic module is defective. In rare cases the terminal block on the display module side is displaced. Also check the same terminal block on the main module. From the experience of operation of similar SM, the firmware of the non-volatile memory EEPROM was not the cause of such a defect
F13 Drying temperature sensor circuit open or short-circuited (drying oven only), Proceed in the same way as in case of error F0Ç, the only difference being that the drying temperature sensor circuit is different
F14 Drying heater doesn’t work (only for SM with dryer). Check heating element power supply as well as heating element itself
F15 Dryer heating element relay is out of contact (only for VM with dryer). Check heating element power supply and heating element circuit
F16 Drum blocked (only in vertical loader). Check drum lock (power supply to locking solenoid)
F17 Door lock is not blocked (or door is open (for SM with Easy Door function). Check 220V voltage between pins 3 and 4 of J4 connector (not in STANDBY mode) and also between pins 3 and 5 of the door locking switch. Check that the door lock feedback microswitch is operating (with the door closed and the machine off) on pins 1 and 2 of connector J4 of the electronic module. Check that the wires from connector M to the sunroof lock are securely connected. Check if the latch is securely locked. Change of door lock. Replace electronic module. If SM without “Easy Door” function, carry out the same operations (see F18.3 for the electronic module and F18.4 for the electronic module). above), only check 220V voltage on pins 2, 3 of connector J4 and on pins 1, 3 of the door locking switch. Do not check the microswitch in this case. as there is no Easy Door function The firmware of the non-volatile memory EEPROM has absolutely nothing to do with it
F18 An error in communication between the controller chips and the DSP (Processor control of the induction motor) in the main electronic module. Replace the main electronic module This error is extremely rare, in any case, we have not met it yet

EVO-II modules and their peripherals

As we know, the EVO-II washing machines have many modifications. they differ not only in functionality and appearance (only their control panels have several variants), but also in their electronic “stuffing. Let’s look at the main varieties of EVO-II modules. Note, that the external appearance of the indication modules (with LCD display and LED indicators) is not presented in the figures. Actually there is no point, because the indication modules are simple enough and have only two sockets: one is for communication with the main module, and the second one is for connecting the program selector.

Indesit washing machines error codes (Indesit)

Before listing the error codes, let’s first take a closer look at the different methods of displaying errors used in Indesit washing machines: they can vary greatly depending on the model range.

The earliest models

The first models with EVO-I control unit in which error indication appeared (W, WS, WDS series, etc.д.), had very modest means of display and control: only the selector knob and a couple of indicators. To display an error, the selector turned continuously and the power indicator (for about two seconds) lit up at 5-second intervals: it could flash with varying frequency or be solid. Now, the error number. is the number of these 2 second blinks.

Error code indication by indicators

The later EVO-II models have a much richer control panel, with many indicators (light emitting diodes), but still no display: here the error code was indicated by means of certain blinking lights. The following principle was used: five indicators were assigned a conditional number in the power of two. 1, 2, 4, 8, 16. and the error code (or rather, number) was defined as the sum of the numbers of lit or blinking LEDs; for example, when LEDs 1, 2, and 4 were lit, the error was 11 (128). It should be borne in mind that different models of the dashboard looks slightly different, respectively, and the location of indicators to display the error will be different. Here are the most common variants.

With Low-End Control Unit (WIU, WIUN models, etc.).д.)

For your convenience, here is the table of equivalence of indicators and error codes: it does not contain the specific names of indicators (they depend on the SM model), but the numerical equivalents of LEDs. names can be seen in the pictures above.
