The situation when the washing machine Ariston stops spinning clothes is one of the most common and unpleasant problems for the owner. Instead of the expected dry clothes after the end of the cycle, you find a wet, heavy lump from which water is literally dripping. This is not just an inconvenience that requires manually unscrewing things, but also a signal that a failure has occurred in the operation of a complex electromechanical device.
Why Ariston washing machine does not spin? There can be many answers: from a banal clogged drain filter to the failure of an expensive control module. Modern models such as the series Hotpoint-Ariston, are equipped with a self-diagnosis system, which often helps to narrow down the search, but does not always show the exact error code on the display. Understanding the physics of the spin process - rotating the drum at high speeds - will help you quickly navigate the nature of the breakdown.
In this article we will analyze in detail the main components responsible for spinning and the sequence of actions when checking them. We will look at both simple problems that can be fixed in 15 minutes, and complex technical faults that require professional intervention or deep disassembly of the unit.
Diagnosis by error codes and symptoms
The first step in identifying the reason why Ariston washing machine does not spin, should be monitoring the behavior of the equipment and deciphering the indication. Models Ariston and Hotpoint Certain lights flash frequently or display alphanumeric codes on the display. For example, a flashing temperature light or faucet icon may indicate problems with the drain, which is a direct barrier to proceeding to the spin stage.
Pay attention to the nature of the sound. If the machine hums but the drum does not turn, or the rotation is jerky, this narrows down the suspects to the motor, brushes or belt. If the drum stands absolutely still and you can’t even hear an attempt to start the motor, the problem may lie in the electronics or the hatch is blocked.
- 🚿 Code F05: Malfunction of the pressure switch or problems with draining water (the machine “thinks” that there is water still inside).
- 🔌 Code F06: Problem with the engine or tachometer (no signal about the rotation speed).
- 🔒 Code F07: Malfunction of the heating element or heating element relay (often blocks the spin cycle due to a violation of the heating logic).
- 🧠 Code F08/F09: Problems with the EEPROM or control module.
It is important to understand that the absence of an error code on the display does not mean that all systems are working. Mechanical failures, such as bearing wear or belt stretching, may not be recorded electronically as an “error”, but physically prevent normal spinning.
⚠️ Attention: If you see an error code, write it down before unplugging the machine. A power reset will often erase the temporary code from memory and the diagnostic will have to be started again.
Problems with water drainage as the main reason
Algorithm for operation of any washing machine, including Ariston, is designed in such a way that spinning is impossible if water remains inside the tank. The water level sensor (pressostat) blocks the command at high speeds to avoid water hammer and damage to the bearings. Therefore, if Ariston washing machine does not spin, in 80% of cases it is poor-quality drainage that is to blame.
You should start checking with the most accessible element - the drain filter. It is located at the bottom of the car behind the decorative panel. If this unit is clogged with lint, coins, or buttons, it creates a plug that the pump cannot push through. The water sits in the tank, the machine waits, the timeout expires, and the cycle ends without spinning.
If the filter is clean, check the drain hose. It could have become twisted during installation or clogged at the connection to the sewer. It is also worth checking the drain pump itself. The pump impeller may have become threaded, causing it to jam or reduce performance.
☑️ Checking the drainage system
In some cases, the problem lies in the pressure switch itself. If its tube is clogged with dirt or a water plug has formed in it, the sensor transmits a false signal about the presence of water to the control module. Cleaning the tube and the sensor itself often solves the problem without replacing parts.
Motor and brush assembly malfunctions
The engine is the “heart” of the spin cycle. In washing machines Ariston Most often, commutator motors are used, the service life of which directly depends on the condition of the graphite brushes. Over time, the brushes wear out, contact with the commutator deteriorates, and the engine loses power or stops starting altogether. This is the classic reason why Ariston washing machine does not spin after several years of use.
Signs of brush wear: the machine hums, jerks, but does not accelerate to the required speed, or spinning occurs only at low speeds. Sometimes you can hear a characteristic cracking sound or even see sparking through the vents. Replacing brushes is a simple procedure, but it requires removing the engine and partially disassembling it.
In addition to the brushes, you should pay attention to the tachometer. This is a small element on the motor housing that reads the rotation speed of the shaft and transmits the data to the control board. If the tachometer falls off or fails, the control module “does not see” the rotation and emergency stops the process, fearing that the drum will accelerate without control.
How to check the tachometer?
The tachometer is a coil with a magnet. Its resistance should be within 60-70 Ohms. If the multimeter shows an open or short circuit, the part must be replaced. Also check whether the tachometer ring fits tightly on the motor shaft.
Do not forget about the interturn short circuit of the motor windings. This is a more serious malfunction, which is often accompanied by a burning smell and strong heating of the engine. In this case, engine repair is not economically feasible; its complete replacement is required.
Drive belt stretched or broken
Transmission of rotation from the engine to the drum in machines Ariston carried out using a poly V-belt. Over time, the rubber dries out, loses its elasticity and stretches. A stretched belt begins to slip on the pulley, especially under load, when the laundry is distributed unevenly. The car tries to accelerate the drum, the belt whistles, but the speed does not gain.
If the rack breaks completely, the engine will hum as it turns its small gear, but the drum will remain motionless. Checking the condition of the belt requires removing the rear cover of the machine. Visually assess the tension: when pressed with your finger, the belt should bend by about 1-1.5 cm. If it dangles like a rope, it needs replacement.
- 🔍 Visual inspection: Check the belt for cracks, abrasions and delamination.
- 📏 Marking: When purchasing a new belt, pay attention to the number of grooves and length (indicated on the belt itself, for example, 1138 J6).
- 🔧 Tension: A belt that is too tight will place unnecessary stress on the engine and tank bearings.
Sometimes the cause of slippage is not the belt itself, but the contamination of the pulley. Oil or detergent on work surfaces reduces the coefficient of friction. Wipe the motor pulley and drum with alcohol or degreaser before installing a new belt.
When replacing the belt, do not use screwdrivers or sharp tools to tighten it - this will easily damage the rubber structure. Tension occurs due to the design of the motor and pulley.
Malfunctions of the heating element and its effect on spin
It may seem strange, but the heating element (heating element) directly affects the ability to spin. In the logic of many models Ariston The rule is laid down: if the water does not heat up to the set temperature within a certain time, the washing cycle is interrupted or switches to rinse mode without spinning. This is protection against running “idle” when the heating element is broken.
If the heating element is covered with a thick layer of scale, its heat transfer deteriorates, the water heats up slowly, and the machine goes into a heating time error. In addition, a breakdown of the heating element on the housing can cause a current leak, which leads to malfunctions of the control module and chaotic behavior of the machine, including refusal to spin.
The heating element is checked with a multimeter in resistance measurement mode. The normal resistance of a working heating element with a power of 1900 W is about 25-30 Ohms. If the device shows one (open) or zero (short circuit), the element is faulty.
| Symptom | Possible reason | Test method |
|---|---|---|
| The machine heats up, but does not spin | Drain clogged, pressure switch faulty | Checking the filter and pipe |
| It hums but doesn't turn | Worn brushes, jammed bearings | Removing the engine, checking by hand |
| Mid-cycle stops | Heating element malfunction, module failure | Testing the heating element with a multimeter |
| Whistle and vibration | Belt slippage | Visual inspection of the belt and pulley |
Mechanical damage: bearings and shock absorbers
The most severe and expensive category of faults is the destruction of the bearing assembly. If Ariston washing machine does not spin Due to the hum, similar to an airplane taking off, and strong vibration, most likely the drum bearings have failed. Water got into the bearing, washed out the lubricant, and corrosion and wear began.
Operating a machine with faulty bearings is dangerous: an overclocked drum can damage the tank or even pierce it. In addition, due to shaft play, the engine cannot develop the required speed, and the electronics emergency brake the rotation.
It's also worth checking the shock absorbers. If they “leaked” or weakened, the tank will hit the body of the machine during the spin cycle. An imbalance sensor (if the model has one) or simply mechanical shaking can cause the program to reset. The test is simple: press the tank from top to bottom. It should return to its original position without swinging. If the tank hangs like jelly, the shock absorbers need to be replaced.
⚠️ Attention: Replacing bearings in washing machines Ariston often requires cutting the tank, since in many models it is non-separable. This is a labor-intensive operation that requires sealing the tank after repair.
Control module malfunctions
If all mechanical and electrical components are in good condition and Ariston washing machine does not spin, the problem may lie in the “brains” of the device - the control module. Voltage surges, moisture or manufacturing defects can lead to failure of the motor or pump control triacs.
A common problem is contacts falling off or microcracks in soldering due to vibration. In this case, the module simply does not supply voltage to the motor at the right time. Repairing the module requires the qualifications of a radio engineer: resoldering elements, checking tracks and firmware.
Diagnostics of the control module should be carried out last, making sure that all actuators (motor, pump, heating element) are in good working order.
Sometimes simply resetting errors or “rebooting” the machine helps: disconnect it from the network for 15-20 minutes. This will allow the capacitors to discharge and the logic circuit to reset errors. If after switching on the problem recurs, professional board repair is necessary.
Frequently asked questions (FAQ)
Why does the machine spin only at low speeds?
Most often this is a sign of wear on the motor brushes. They are still in contact with the commutator, but the contact area is small, and the motor cannot develop full power. It could also be due to a stretched belt or unbalanced laundry.
The machine draws water and washes, but does not drain or spin. What to do?
This is a classic sign of a clogged drain. Check the filter, the pipe from the tank to the pump and the pump itself. A bra wire or large object may have gotten into the system.
Is it possible to run the spin cycle separately if the wash went well?
Yes, most models Ariston have the "Drain + Spin" function. Select this program on the selector. If the machine does not spin in this mode, then the problem is in the units responsible for rotation or draining, and not in the washing logic.
The engine hums, but the drum does not spin. Is this a renovation?
There is a 90% chance that this is wear on the motor brushes. This is a consumable item that is changed every 5-7 years. The repair is inexpensive and quite doable at home if you have the tools.
How to reset an error on an Ariston washing machine?
Usually it is enough to turn off the machine with the button and unplug the plug from the socket for 10-15 minutes. For some models, there is a combination of reset buttons (for example, holding the "On/Off" button and another function button for 5 seconds), but a full power reset always works.
