The situation when your Indesit washing machine obediently opens the valve, fills the tank to the required level, but then freezes in anticipation, familiar to many owners of this equipment. Instead of the expected hum of the engine and rotation of the drum, you only hear silence or a repeated click, and an error may appear on the display or the time indicator may simply blink. This behavior of the equipment does not mean that the unit is completely out of order, but the problem cannot be ignored, as it may indicate specific failures in the cycle startup chain.
Most often, the reason lies in a violation of the logical sequence of electronic actions. The machine “thinks” that the conditions for start have not yet been met, or that some critical unit has not signaled readiness. Depending on the model, be it classic Indesit WIUN or more modern series Indesit Smart, the algorithm may differ slightly, but the physics of the processes remains the same. There is water, but energy is not transferred to the engine, or heating does not occur on time.
In this material we will analyze in detail the main components that are responsible for the transition from the “water collection” mode to the “washing” mode. You will learn how to carry out initial diagnostics yourself, which elements most often fail and whether it is worth calling a specialist for replacement. control module Or you can limit yourself to cleaning the filters.
⚠️ Attention: Before starting any diagnostic work, be sure to disconnect the washing machine from the electrical network! Working with live electrical appliances is deadly.
Problems with water heating: heating element malfunction
One of the most common reasons why washing machine Indesit draws water and stops, there is a malfunction of the heating element. Many users are surprised: why doesn’t the machine spin the drum if it hasn’t heated the water yet? The fact is that most modern washing programs involve heating water to a given temperature before starting active mechanical actions. The electronic module will not give the command to start the engine until temperature sensor will not record the achievement of the desired temperature.
If heating element (tubular electric heater) has burnt out or is covered with a thick layer of scale, the water does not heat up. The machine waits for a signal from the temperature sensor for an infinitely long time. In some models, after 10-20 minutes of waiting, it will still start washing with cold water, but more often the process simply freezes. A heat-related error code, such as F05 or F07, may appear on the display, depending on the specific version.
Diagnostics of the heating element is carried out using a multimeter in resistance measurement mode. It is necessary to remove the back cover, find the heater contacts, disconnect the wires and ring the element. The normal resistance of a working heating element with a power of 1.7-1.9 kW is approximately 25-35 Ohms. If the device shows one (open) or zero (short circuit), the element requires replacement.
How to check a heating element without a multimeter?
It is difficult to visually determine the breakdown of the heating element, but you can inspect it for swelling, cracks or heavy scale deposits. If the tube shows black spots or is deformed, replacement is inevitable. However, the absence of external signs does not guarantee serviceability - only measurements with a device give an accurate result.
In addition, it is important to check not only the integrity of the spiral, but also the absence of a breakdown in the housing. One probe of the multimeter is applied to the contact, the other to the metal tube of the heating element or to the body of the machine. Resistance should tend to infinity. If there is at least some indication, it means that depressurization has occurred, and it is dangerous to operate such a heater.
The lack of rotation of the drum when water is drawn in 60% of cases is due to the fact that the control module is waiting for a signal to heat the water, which does not arrive due to a burnt-out heating element.
Malfunctions of the water level control system
The second key element, without which washing is impossible, is pressure switch (water level switch). It is this sensor that tells the control module that the tank is full and the water can be turned off, starting the next stage. If the pressure switch “lies” or does not transmit a signal, the machine can draw water endlessly or, conversely, draw a little and get up, “thinking” that there is not enough water.
Often the problem lies not in the sensor itself, but in the connecting tube going from the tank to the pressure switch. It may become clogged due to residual powder, lint or condensation. Air does not pass through the tube, pressure is not transmitted to the sensor membrane, and the machine does not understand that the water level has been reached. There may also be a microcrack in the tube through which air is being released.
To check you need:
- 🔹 Remove the top cover of the machine and find the pressure switch (usually a plastic washer with connected wires).
- 🔹 Disconnect the transparent or colored tube and blow it out, clear it of blockages.
- 🔹 Check the sensor itself by blowing into it with your mouth and listening to the characteristic clicks (with the multimeter connected, the resistance should change).
If the tube is intact and clean, and there are no clicks or they do not occur correctly, replacement will be required level relay. This is an inexpensive consumable that can be easily changed independently. It is important to buy a pressure switch with exactly the same number on the case as your old device, since they have different response pressures.
When installing a new pressure switch tube, make sure that it is pulled tightly onto the fittings and secured with clamps. Even a small air leak will result in incorrect water level readings.
Motor brush wear
If water is collected, heating is successful (or the program allows washing without heating), but the drum does not rotate and the characteristic hum of the motor is not heard, there is a high probability of wear graphite brushes. In commutator-type engines, which are equipped with most models Indesit, the brushes transmit current to the rotor. Over time, they wear out, contact deteriorates, and the engine stops starting.
Symptoms of brush wear often appear gradually. At first, the machine may spin poorly, then stop spinning at high speeds, and eventually stop completely. Sometimes the engine may jerk or make a cracking noise as it tries to start turning, but there is not enough power from the sparking contact.
The process of replacing brushes requires partial disassembly of the machine:
- 🔸 Remove the back cover and drive belt.
- 🔸 Unscrew the engine mounts and remove it from the housing.
- 🔸 Remove the brush holders, remove the old brushes and compare them with the new ones (graphite residue less than 1.5 cm requires replacement).
When replacing brushes, be sure to inspect the motor commutator (the copper part of the rotor). It should be clean, without black deposits and grooves. If dirt is visible on the collector, it must be carefully removed with alcohol or an eraser. Deep grooves indicate that the engine has completely exhausted its service life.
☑️ Replacing motor brushes
Control module malfunctions
The most difficult and expensive failure option is failure electronic control module. It is the “brain” of the machine that receives signals from all sensors and issues commands to the actuators. If the motor control triacs on the board burn out, the tracks burn out, or the firmware fails, the machine may behave inappropriately: take in water and stop, ignoring the serviceability of other components.
Often the module suffers from power surges or moisture ingress. A visual inspection of the board may reveal blackening, swollen capacitors, or burnt marks. However, the breakdown is not always visible to the eye - sometimes the burnt element looks completely intact. In such cases, professional diagnostics with an oscilloscope is required.
It is worth noting that before replacing the module, all other causes must be ruled out. Very often, technicians diagnose a board failure when the problem was simply a stuck “Start” button or a broken wire. Module repair can be done in a specialized workshop, which is cheaper than buying a new board, but takes time.
⚠️ Attention: Independent repair of the control board without special knowledge and equipment often leads to complete failure of the equipment. If you are not confident in your abilities, it is better to turn to professionals.
Mechanical blockages and foreign objects
Sometimes the reason the machine stops is trivial and lies in the mechanical blocking of the drum. If a foreign object (a bra wire, a coin, a button) gets between the tank and the drum, it may jam the rotation. The machine tries to start the engine, encounters resistance, the current in the windings increases sharply, and the electronics emergency stops the process so as not to burn the motor.
It is also worth checking the condition of the bearings. If they are destroyed, the drum may move with great difficulty or become warped, creating critical friction. A characteristic sign of problems with bearings is a strong hum and grinding noise when trying to rotate, even if you turn the machine by hand.
Another option is a malfunction drain pump. Some Indesit models are designed in such a way that the remaining water is briefly drained before starting the wash. If the pump is clogged or burnt out, the cycle cannot continue. Check the pump impeller for threads and hair, which often block rotation.

Frequently asked questions and answers (FAQ)
Why does the machine take in water and immediately drain it without starting the wash?
This may indicate a faulty check valve in the drain hose if it is not connected correctly, or a faulty water level sensor that erroneously signals an overflow. It is also worth checking to see if the drain filter is clogged.
Is it possible to start washing if the heating element is burnt out?
Technically, some programs allow you to wash with cold water. However, if the control module is hardwired to check the temperature, the wash will not start. In addition, washing without heat reduces the effectiveness of stain removal and can lead to a deposit of hard salts on the laundry.
How often do brushes on an Indesit engine need to be changed?
The service life of brushes is on average 5-7 years of active use. The rate of wear depends on the frequency of washing, load weight and the quality of the network voltage. At the first signs of sparking or a decrease in engine power, preventive maintenance should be carried out.
What should I do if, after replacing the heating element, the car still does not heat up?
It is necessary to check the power supply circuit of the heating element on the control board. Often, a triac or relay on the module burns out along with the heater. Also make sure that you have connected the wires correctly and that the temperature sensor is firmly attached to the heating element.
Is it dangerous to operate a machine that stops periodically?
Yes, it's dangerous. If the problem is contact overheating or current leakage, it may cause a fire or electrical shock. In addition, constant attempts to start with a blocked drum can permanently damage the engine or belt.
