Ariston boiler, error codes with explanations and repair examples

At the beginning of the wash or during the spinning process, code F05 appeared on the display of the Ariston machine. Which parts are faulty? How can I remove this error?

This alphanumeric combination usually occurs before a drain. Sometimes it is preceded by strange humming sounds coming from the area where the pump is located. Although such an error can occur from the very beginning of program execution, and in the middle of the algorithm. In many cases, you can eliminate the causes of the F05 code yourself. If nothing helps, or you simply don’t want to spend a lot of time sorting through parts, you can always contact us: washing machine repair Kazan.

Causes of the "accident"

Code F05/F5 tells the owner that there is a problem with the drain system. Not all Ariston SMAs have a display. On the oldest models, this error manifests itself as a “pulsating” burning of one of the bulbs, with 5 short flashes, then a short break occurs, and everything repeats again. The door lock is activated. On later models of Ariston units, error F05 is expressed in the flashing of the “super cleaning” and “extra rinse” icons. In other variations of washing machines of this brand, problems with drainage are indicated by the simultaneous pulsating lighting of the “blocking” and “drain” indicators.

The following details may be the culprits for such an error:

1. Electronic controller.
2. Drain filter.
3. Water pump.
4. Pipe going to the drain pump.
5. Drain hose.
6. Sewer blockage.
7. Pressure meter.
8. Wiring connecting the pump and pressure switch to the control module.

Troubleshooting methods

To clear error F5 and continue washing, you can do the following:

1. Turn off the Hotpoint Ariston machine first with the power off button, then remove the plug from the socket and wait a while. Sometimes the appearance of code f5 is associated with a slight malfunction in the electronic module, and after turning it on again, the washing may continue in the specified mode.

2. Check the drain system for blockages. You must first turn off the power to the unit, turn off the water supply, and remove the liquid from the tank (in most models, an emergency hose is provided for this, located behind a small door at the bottom of the SMA). Next, unscrew the drain filter plug, remove it and remove foreign objects. Inspect the pump impeller, which is located next to the filter. It should rotate freely. Check the passage of the drain hose. To do this, you need to dismantle it and pour liquid through it. There may be a blockage in the drain. If the drain of the Ariston machine is connected to the sink, you need to turn on the water from the mixer that is connected to it and see how fast it drains. If you have not yet drained the liquid from the machine, then disconnect the hose from the entrance to the sewer and try dumping the water into a bathtub or bucket. If it drains freely, there is a sewer blockage. Also check the pipe inside the machine that connects the tank to the pump. But to do this you will have to look inside the unit.
3. If everything is in order with the waste fluid discharge system, you need to ring the pressure switch and pump with a multimeter. To access them, you need to remove the rear panel of the unit. By the way, if after error F5 the F11 indication lights up, then the problem is with the pressure switch. The wires leading from the level sensor and drain pump to the control module also need to be checked. If one of them is disconnected or becomes unusable, then sufficient voltage is not supplied to these devices and they cannot work normally.
4. The most serious is a breakdown in the electronic part. The tracks in the control module may have deteriorated, one of the small components may have failed, the processor may have crashed, or a flashing may be required. It is better to entrust the repair of the electronic unit to a professional from the workshop.

Error F-05, F5 in the ARISTON washing machine: what does it mean in Hotpoint Ariston and how to fix it Washing machines are designed by manufacturers for trouble-free operation for many years, but over time, these complex household appliances malfunction due to wear and tear of their component parts and assemblies.

Meaning

Error F05 in the Hotpoint-Ariston washing machine does not appear immediately after switching on, but after a certain time. The alert appears for several reasons. As a rule, the code indicates that there are problems with switching washing programs, as well as with rinsing or spinning the laundry. After the code appears, the equipment stops working, but water remains in the tank in most cases.

Modern household equipment is equipped with a large number of components and components. All of them are controlled through a special module. In performing its function, the control module works taking into account sensor readings. They provide information about how the washing program is carried out.

The pressure switch is one of the most basic sensors in a washing machine. It monitors the tank's fullness with water and gives a signal when the waste liquid needs to be drained. If it fails or starts to work incorrectly, an error code F05 appears on the display.

What does error f05 mean in an Ariston washing machine?

If the Ariston washing machine shows code f05 on the display some time after turning it on, this means that there are some problems with switching the washing mode to the rinse mode, or from rinsing to the spin mode.

In this case, the machine stops the specified program, but in most cases of such an error, the water remains in the tank. The washing machine has many parts and components that are controlled by an electronic module.

The electronic module, in turn, when performing a given program, relies on the readings of certain sensors, which inform it about the completion of all steps of the washing cycle. One of these sensors is a pressure switch. This unit is responsible for monitoring the filling of the tank with water to the required level and also informs the control unit when the used cleaning solution is completely drained.

If there are any incorrect pressure switch readings that do not correspond to the program, the electronic unit stops the washing machine and displays a fault code. If there is no water drainage, there is code f05.

Purpose of sensors and where they are located

We look at the pictures, read the inscriptions - here we have collected all the sensors used in the boiler and reporting any error. With the exception of the pressure sensor, it is not included in this diagram, since it is not used in this boiler model. Well, a sensor with a pressure gauge is not yet indicated, I think everything is clear there, it’s just an indicator reporting the amount of pressure in the circuit. By the way, in some modifications of boilers, the submersible temperature sensor in the DHW circuit - NTCs - may also not be installed.

Reasons for error f05 on an Ariston washing machine

Error F05 in the Ariston washing machine occurs for a number of reasons:

• Electronics can sometimes malfunction due to inappropriate voltage in the supply network or failure of some electronic components that make up the entire control unit.
• It is best to let a specialist in this field of repair deal with such a malfunction.
• Independent attempts may lead to additional financial costs for the purchase of a new expensive module;
• A common cause is a clogged drain system.

It occurs in different places in the drainage line.:

• In the pipe from the tank to the drain pump . An obstacle to draining water there can be made by small things that were pulled in during washing from the drum. Such items can be children's clothes, socks, handkerchiefs, parts of candy packaging, etc.;
• In the drain pump filter . This filter element is designed to prevent foreign objects from entering the drain pump to prevent it from jamming. Gradually, a lot of toothpicks, ear sticks and clothing accessories collect in the filter. With their accumulation, it becomes difficult for the drained water to pass into the sewer and when the drain command is given, code F05 appears on the Ariston washing machine;
• Malfunction of the drain pump itself . The drain pump in washing machines includes a “wet rotor” in its design, rotating on bushings directly in the drained water itself. Due to the strong hardness of the water, the shaft and bushings wear out and the rotor jams in the stator. This can happen at first unnoticed by users due to the pump operating “every once in a while.”
• The machine can perform the washing mode flawlessly and switch to rinsing, but during one of the rinses refuse to drain the water completely, and the module will receive positive readings from the pressure switch. But experienced housewives begin to notice poor quality of washing due to such incorrect operation of the pump, which then completely fails and code f05 appears. A jammed pump impeller can also be caused by a piece of toothpick passing through the filter.
• Threads from clothing can also get wrapped around the pump shaft;

Ways to eliminate error f05 in an Ariston washing machine

If you decide to eliminate error f05 in the Ariston washing machine on your own, then you should look for the cause in the following order:

• First of all, disconnect the machine from the electrical network;
• Then move it away from the wall so that by tilting it back you can place a container (in the form of a bowl or basin) under it with a volume of about 7-10 liters and unscrew the drain pump filter. The water will drain from the tank, pay attention to the presence of foreign objects in the filter, water in the container and in the sink itself (from which the filter was unscrewed);
• The pump impeller in the shape of a cross is clearly visible in the sink. Scroll it and make sure it rotates freely;
• If, when dismantling the filter, the water does not drain from the tank, then the blockage has formed directly in the pipe leading from the tank to the drain pump. It is necessary to remove it and clean it of things that have fallen there;
• If the pipe and filter are clean, the pump impeller rotates freely, then check the drain hose from the pump to the sewer. This can be done from different ends using air pressure or water from the tap. If the hose is connected to the sewer through the sink siphon, check the siphon sump and clean it;
• We check the pressure switch tube with air pressure, and also inspect the pressure switch contacts for the presence of oxidation;

• If all the steps taken are unsuccessful, then we dismantle the drain pump. To do this, unscrew it from the body of the washing machine complete with filter, remove the hoses and wires from it, and take it out. Then we disconnect it from the filter housing. We check the resistance of the stator winding with a multimeter; it should be in the range of 170-230 Ohms. We check its shaft for the presence of transverse play by shaking it by the impeller. If possible, remove the rotor from the pump and check for wear on the shaft. If wear is visible, the pump should be replaced.
• The fact is that mechanical wear on the shaft and bushings provokes the rotor to jam in the stator, and this can happen at the initial stage of wear and not every time the drain is turned on. A malfunction of the drain pump can only be eliminated by replacing it with a new analogue; the original part is best suited. Moreover, today there are few manufacturers of drain pumps of decent quality.

Cleaning the drain system

A fairly common reason for an Indesit machine not draining properly is the drain filter. It is designed to catch small items that accumulate during washing. Over time, threads, scraps of fabric, and buttons settle on it. Error F05 may appear precisely because of a dirty filter.

When eliminating error F05, before starting work, you must disconnect the Indesit washing machine from the mains and remove water from the drum. Accessing the filter is easy. It is located at the bottom of the machine, depending on the model, closed by a swing door or a removable panel. To remove the filter, simply turn it counterclockwise and pull it towards you.

Even though the water has been removed from the drum of the Indesit machine, it is a good idea to prepare a rag and a bucket. There is guaranteed to be some water left inside the machine.

The filter of the Indesit washing machine is washed under the tap and cleaned of accumulated dirt. Next, to eliminate error F05, check the drain hose. To do this you need to do the following:

1. Loosen the hose fastening on the sewer outlet.
2. Remove the hose and quickly lower it into any container to drain the remaining water.
3. Rinse the hose with running water.

When checking and eliminating error F05, it will not be amiss to make sure that there is no blockage in the sewer system. If necessary, it can be cleaned with a thin metal cable or bent wire.

How to avoid error f05 on an Ariston washing machine

It is impossible to completely avoid the occurrence of error f05 due to the inevitable temporary wear of the drain pump itself, but you can slow down its production. You can also avoid unnecessary blockages in the drain system.

For this:

• When putting laundry into the drum of the machine, carefully check the contents of the pockets and the reliability of fastening the clothing accessories;
• Wash small items in special bags;
• To avoid scale formation, use only high-quality water and detergent when washing;
• When connecting the washing machine, pay special attention to the installation of the drain hose. It should not have sharp bends, where a jam forms. Also, the drain hose should be connected to the sewer at a height of 50-60 cm from the floor level, but it is not recommended to connect it too high. It should not be much longer than the required size, this will make it difficult for the pump to freely drain waste water;
• Periodically, it is necessary to carry out preventative maintenance on your washing machine to remove grease, scale and other unwanted deposits. This procedure will not only clean the machine of dirt but also prevent the appearance of unpleasant odors on clothes after washing;
• To avoid damage to the electrical parts of the machine, the device should only be used when the required voltage is stable and in well-ventilated areas. It is not allowed to use electrical appliances during a thunderstorm.

Error recognition

The Ariston electronically controlled washing machine shows error F 05 on the display.

Electromechanical machines report a malfunction as follows:

• In machines from the Ariston Margherita series, the power light flickers five times intermittently. Additionally, the “Key” - “Lock” light is on, the program control selector rotates clockwise and clicks.
• Ariston AVL, AML, AVSL models display code F05 with a flashing “Super Wash” - “Extra Rinse” indicator. At the same time, the “Key” light flashes frequently.
• The Hotpoint Ariston CMA type ARSL, ARXL will display the code by repeated flashing of the “Drain” - “Key” light.
• On the Hotpoint-Ariston Aqualtis washing machine, the 40° temperature indicator for washing in cold water flickers.

Have you determined that your machine is giving an error F05, F5? Now you need to find out what the fault code means and how to fix the problem at home.

Simplify diagnostics

If the breakdown occurred specifically in the pressure switch, then Hotpoint Ariston washing machines released in 2022 will display error f11 after a restart. Some earlier models also have this feature. However, sometimes this requires restarting the program several times.

An important point is the fact that restarting should be done after completely turning off and de-energizing the machine for at least 30 seconds.

Description and reason for the code

The display shows error F5 in the Ariston washing machine, what does this mean: the drain pump is broken, because of this the pressure switch does not recognize the presence of water in the machine.

1. The drain filter or hose is clogged, or the sewer is clogged.
2. There is not enough energy supplied to the pressure switch, or the device is completely out of order.
3. There is not enough energy for the normal functioning of the drain pump sensor. The device may break.
4. The pump inlet valves have failed.

Try to remove the error and solve the problem without calling a technician.

Pump inlet valve malfunction

The inlet (fill) valve is responsible for the timely filling of the tank and draining of water. This is a non-separable part, which is replaced if faulty. When repairing an Ariston machine, you should know that the valve is opened by a command from the control module by supplying electricity to the Aqualtis magnetic coil. If F5 is faulty, the drum does not fill.

To fix this, you need to remove the high pressure hose. The inlet strainer may become clogged with rust and particulates after major repairs to the central water main. In houses with water supply from artesian wells, a deep pump can cause clogging of these engineering systems with sand from the drilling structure.
