Common breakdowns of Indesit automatic washing machines

Many homes choose Indesit washing machines because of their reputation for dependability and affordability. But just like any other appliance, they occasionally have problems.

Even the greatest washing machines can experience issues over time that cause you to rethink your laundry schedule. Knowing the typical malfunctions will enable you to diagnose and resolve problems more quickly, regardless of how minor the issue may be.

This post will examine common issues with Indesit washing machines and provide explanations for their occurrence as well as solutions. We’ll cover the most common problems that users encounter, from sudden stops to strange noises.

Weaknesses of Indesit washing machines

The main cause of breakdowns in SM is a failure to follow operating guidelines. Moreover, tubular heating elements suffer from the salinity of hard tap water (TENs). Design flaws and manufacturing defects are unavoidably mentioned as sources of malfunctions. The areas that are most susceptible are:

1. Heating elements often fail not only in Indesit washing machines, but also in units of other popular brands. This is facilitated by scale that forms on the heating tubes, because Italian designers do not provide the heating elements with a protective coating.
2. Network filters often break down during the first 5 years of operation. In addition to manufacturing defects and high humidity, large voltage drops in 220 V networks have a negative impact on them, leading to breakdown of capacitors.
3. Bearings, on which the drum rotates are the "Achilles heel" of Indesit washing machines (in this equipment they fail more often than in units of other brands). Repair requires complete disassembly of the machine, so only a qualified specialist can perform the replacement.
4. Control units (hereinafter also referred to as ECUs) of Italian design also cannot be called reliable. This is especially true for earlier models of equipment. Electrical circuits are not designed for a wide range of supply voltage, and boards are not designed for high humidity. In addition, weak network filters cannot smooth out voltage surges in 220 V networks, which leads to damage to the ECU.
5. Tachometers of electric motors are also not unreliable. Their failure entails failures in the operation of electronics, since the sensor transmits information about the number of revolutions of the electric motor to the control unit. You can replace the part yourself.

The majority of washing machine malfunctions are fixable by the average person, but some require the expertise of a qualified technician.

The types of malfunctions that occur during operation of Indesit washing machines can be identified with the use of their sophisticated control systems. Alphanumeric codes are used on the displays to represent error information.

Because of their low cost and dependability, Indesit automatic washers are well-liked; however, just like any other appliance, they occasionally experience common problems like the drum not spinning, the water not draining, or malfunctions with the electronic controls. Users can ensure their washing machine continues to function properly for many years by being aware of these common breakdowns and taking prompt action to address and resolve them.

Failure codes of Indesit automatic washing machines

Both models with and without displays are available for Indesit washing machines. In the first example, every Indesit washing machine malfunction has a unique, easily readable alphanumeric code. It is a little trickier to use automatic machines without displays. Decoding the indicator signals, for instance, allows one to identify faults in the Indesit WISL 102 washing machine.

Indicators and the values that correspond to them, which the WISL series units use to decode the fault code

Similarly, other models of the budget WISL and WITL series (WISL 82, WISL83, WISL85, WISL103, WISL105, WITL86, WITL106, and others) with EVO-II control units of the AVL modification determine the type of breakdown.

The same faults are displayed slightly differently in washing machines equipped with EVO-II control units of the Low-End modification (WUIN 81 and WISE 10 for example).

The mechanical control modules EVO-I serve as the foundation for the earliest models. These consist of W, WS, WT, and WI series washing machines, such as W84TX, W105TX, and others. The number of times the network indicator blinks between pauses in this instance indicates when the Indesit washing machine breaks down. The program selector in this instance is always rotating.

The table displays the decoding of information codes and combinations of illuminated indicators:

There is no electric motor functioning. The electric motor’s brushes are worn out, the motor windings have broken, the ECU is malfunctioning (the control triac has burned out), and the cable connections’ contacts are broken.

Inaccurate information about how the electric motor is operating is sent to the ECU. It’s possible that the wiring between the tachogenerator and the ECU is defective or that the tachogenerator itself is damaged. It is possible that the ECU’s triac isn’t working properly.

The temperature sensor isn’t working properly, which prevents the ECU from knowing the water’s temperature. It’s possible that the connection circuit has broken.

The pressure switch, which is the tank’s water level sensor, is broken. The relay simultaneously reports that there is an overflow of water in the tank and that the tank is empty. Other possibilities include the water supply system not having any water in it, a clogged inlet valve filter, a broken cable connection contact, or damage to the ECU.

The tank does not empty of water. There’s a chance the drain pump is broken. A clogged pump filter could exist. It’s possible that the control unit or pressure switch has malfunctioned.

When choosing the washing machine operating program, the control panel’s buttons give false information. Some buttons may not function, or there may be a broken contact in the cable connecting the control panel to the ECU.

The water is not heated by the heating element to the proper temperature. Potential causes include a broken heater, insufficient water in the tank, and improper pressure switch operation.

There is no heating on. Most likely, there is a problem with the ECU control triac. It’s possible that the heater itself or the relay that activates the heating element are broken.

The control unit’s memory, which houses the firmware for every washing program, provides inaccurate data.

The pressure switch indicates that the tank is empty or that no signals are received from its relay even though water is entering it. Either the pressure switch is malfunctioning or there is a broken contact in the connecting connectors. The ECU might be broken or malfunctioning.

There is no drain pump functioning. A break in the connection between the pump and the control module of the control unit could indicate a problem with the pump’s winding.

The indicator board that shows the washing machine’s operating procedure and the ECU are not connected. There is a broken contact in the connecting connectors. There might be an issue with the ECU.

Thermocouple in a drying washing machine is broken. The sensor and ECU may not be in contact.

In the washing machine that has a drying function, the heater does not function. It’s possible that the ECU is malfunctioning or that the sensor’s contact with the control module’s relay is broken.

The machine that has a drying function has a burned-out heating element. There is a broken connection between the control relay and the heating element.

The drum is stuck (only on laundry machines that load vertically).

Prior to washing, the hatch door was not locked. Potential causes include: the hatch locking device (HLD) not working, the door not being closed, or a malfunctioning control module in the ECU.

There is a problem with the control unit’s controller.

The tank is not filled with water. A pinched inlet hose, a broken inlet valve, a clogged mesh filter in the inlet valve, or a lack of water in the water supply could be the cause of the lack of water supply.

As a result, in an emergency, the washing machine’s intelligent control will advise the owner where to search for potential damage.

Troubleshooting

The majority of Indesit washing machine issues are self-fixable. First, unplug the machine’s power plug and de-energize it for ten to fifteen minutes in case of an electronic malfunction. Restart the washing program after that. In order to remove more intricate damage, you will need a multimeter in addition to pliers, flat and Phillips screwdrivers, and a multimeter.

Replacing the network filter

The network cable is usually connected to the network filter, which is usually found beneath the washing machine’s top cover. This unit needs to be replaced right away because it cannot be fixed. While it is easy to fix these Indesit washing machine malfunctions, no one can guarantee that the recently purchased filter will last for a long time.

To prevent interference in the 220 V network, use a network filter.

High humidity damages the filter contacts if the washing machine is placed in the bathroom. Use silicone sealant to ensure the contacts are waterproof. Applying it to dry, clean contact areas is recommended. The filter unit will function for a very long time after this.

Troubleshooting the heating element

Damage to the heater is indicated by the codes F07 or F08 on the SM’s display or indicators. You must remove the machine’s back cover in order to inspect and replace the heating element.

The heating element is situated at the base of the tank, and it is connected to two power wires with terminals and a ground wire.

Remove the wire terminals from the heater and use a multimeter to inspect it. The resistance of a serviceable part is between 25 and 40 Ohms. The heating element needs to be replaced based on other values. Rock the heater from side to side as you carefully remove it after loosening the central fastening nut. Afterward, install the new heating element in the groove by rubbing a soap solution onto its rubber gasket.

Installing new bearings

When spinning, noise, clanking, and other unrelated noises suggest that the tank bearings need to be replaced. Because this kind of Indesit washing machine malfunction necessitates total disassembly of the apparatus, only skilled specialists can handle it.

Changing the bearings in the tank’s crosspiece

You’ll need a certain tool and expertise to remove the old bearings and press in the new ones. The seal needs to be changed, as well as the bearings.

The following video shows how to swap out the metal tank for new bearings in an Indesit CM:

Troubleshooting problems with the control unit

The Italian manufacturer’s ECUs are not made to withstand high humidity, which is common in bathrooms. The main cause of the printed circuit board connectors’ contact pad problems is moisture exposure.

Expert craftsmen should fix Indesit washing machine malfunctions like these because restoring the ECU necessitates knowledge of electronics.

To sum up, I would like to point out that the content does not address issues with the washing machine’s water draining; these issues apply to all brands of machines. Damaged pumps and clogged drain filters are the main causes. You can perform these tasks on your own without the need for specialized knowledge: replacing the pump and cleaning the filter.

Breakdown	Possible Cause
Washing machine not starting	Check power supply, door not closed properly, or faulty control panel
Water not filling	Check water supply, inlet valve, or clogged filter
Machine not draining	Blocked drain hose, clogged pump filter, or faulty drain pump
Excessive vibration or noise	Machine not level, unbalanced load, or worn-out bearings
Door won"t unlock	Faulty door lock mechanism or control board issue
Not spinning or poor spinning	Unbalanced load, faulty motor, or worn-out drive belt

Although Indesit washing machines are generally dependable, they may eventually encounter some common problems just like any other appliance. Being aware of these issues, such as malfunctioning motors, clogged drains, or broken door locks, can help you take care of them early on and save more extensive repairs.

Many of these problems can be avoided with routine maintenance, such as checking the hoses and cleaning the filter. If an issue does occur, it’s usually something that can be resolved quickly, either on your own or with expert assistance.

By being aware of these typical malfunctions, you can prevent future problems with your Indesit washing machine and save time and money.
