Modern household appliances brand Ariston It is equipped with advanced self-diagnostic systems that instantly respond to any malfunctions in work. When the device stops performing the standard wash cycle, a combination of indicators or a digital code indicating a specific malfunction is lit on the control panel. Understanding these signals allows the owner to quickly identify the source of the problem and make a decision: fix the breakdown yourself or call the wizard.
Ignoring the first signs of malfunction, such as pump buzzing or stopping the program mid-cycle, can cause serious damage to the internal nodes. Electronic module Blocks the launch of new programs to prevent kitchen flooding or expensive components from failing. In this article, we will take a detailed look at the basic error codes, methods to fix them, and preventive measures that will prolong the life of your dishwasher.
Principles of the self-diagnostics system
Diagnostic system in dishwashers Ariston (often similar to Indesit) is built on constant monitoring of sensors. The controller checks the water level, heating temperature, speed of rotation of the impeller pump and tightness of the pallet. When any parameter is outside the permissible limits, microprocessor interrupts the program and gives the corresponding signal.
In older models where there is no digital display, the error code is transmitted through the flashing of indicators. Usually it is a combination of flashing light bulbs corresponding to functions (for example, "salt" and "rinse" at the same time). The latest models are equipped with a screen where the error is displayed in the form of alphanumeric code, for example, E01 or F05.
Why doesn’t the machine show an error right away?
The system can accumulate data on periodic failures. If the sensor detects a short-term voltage drop or temporary blockage, the machine may try to compensate for this by increasing the cycle time. The error will only appear when compensation becomes impossible or the failure will occur several times in a row.
It is important to understand that fallback Simply turning off the plug does not always solve the problem. If the physical cause of the malfunction (closure, breakdown of the TEG, wire break) is not eliminated, the code will appear again at the next start. Therefore, the diagnosis begins with an analysis of the conditions under which the failure occurred.
Errors related to water supply and drainage
The most common group of problems faced by users is associated with water circulation disorders. The machine may not be able to draw water, do it too slowly, or, conversely, not be able to drain it. In such cases, codes are broadcast on the display or through indicators that require immediate attention to the hydraulic system.
One common problem is the error indicating the impossibility of draining. The water remains at the bottom of the sink and the cycle does not end. This is often caused by filter clogging, drain hose overbending or malfunction. drain-pump. Also, the cause may be a clog in the sewer pipe, where the equipment is connected.
When installing a dishwasher, make sure that the drain hose is raised 60-80 cm from the floor before entering the sewer. This will prevent the backflow of dirty water and the appearance of false overflow errors.
Problems with water recruitment are often associated with low pressure in the plumbing or a closed inlet faucet. If the pressure is normal, but the car is not gaining water, it could have failed. valve Or clog the mesh filter at the entrance. In some cases, the electronics mistakenly diagnose the leak if the sensor AquaStop in the pallet gets wet due to condensation or a small defect.
- 🚰 Check if the water supply faucet is fully open and if there are any excesses on the hoses.
- 🧹 Clean the rough cleaning filter at the entrance to the machine and the drain filter inside the chamber.
- 🔌 Make sure that the drain hose is not lowered too low (siphon effect).
- ⚙️ Check the operation of the drain pump by starting the drain mode and listening to the characteristic buzzing.
Failures in the heating and drying system
Quality washing of dishes is impossible without hot water. If the dishwasher Ariston It emits an error associated with heating, which means that the water did not reach the desired temperature in the allotted time or, conversely, overheated. This process is responsible for TEN (tubular electric heater) and the thermostat.
A common cause is the formation of scale on the heating element. The lime layer works as a thermal insulator, which makes the TEN last longer, consume more energy and eventually burn out. The electronics detect that the temperature is not rising and give the error code. In other cases, it can “stick” the relay on the control board, which supplies voltage to the heater constantly.
⚠️ Attention: Before checking the TEN with a multimeter, be sure to disconnect the machine from the power grid. Even after switching off, there may be residual voltage on the contacts.
Drying problems often come in tandem with heating errors. If the water is not heated to the final stage, the steam does not form and the dishes remain wet. Also, the fan (in models with turbo drying) or the integrity of the body is responsible for drying. If the door does not fit tightly, the heat goes away, and the drying cycle is interrupted by timeout.

Failures in the circulation pump and motor
A circulation pump is the “heart” of a dishwasher, providing water pressure to wash dishes. If you hear a buzz but the water doesn’t splash, or the machine immediately gives off a motor-related error, the problem lies here. This can be a mechanical locking of the impeller or an electrical breakdown of the windings.
Sometimes (foreign objects), such as fruit bones, toothpicks, or glass shards, fall into the pump and block rotation. In this case, electronic fixes the absence of current in the circuit or, conversely, a sharp jump, and emergency stops the process. Long-term operation of the blocked pump can lead to combustion of the control board.
In more complex cases, the pump itself is required to be replaced or its electrical part repaired. Modern motors in cars Ariston Often made as a single unit with a filter, which simplifies the replacement, but increases the cost of the spare part. It is important to use original components or quality counterparts, as cheap copies can make noise and fail quickly.
- 🔊 Listen: a smooth hum is the norm, intermittent crackling is a sign of debris.
- 🌀 Visually inspect the impeller of the pump through the drain hole (after removing the filter).
- ⚡ Check the resistance of the engine windings (should be within the normal range specified in the manual).
- 🔩 Make sure that the motor mounts are not loosened by vibration.
Ariston's main error codes
For quick navigation on faults, below is a summary table of the most common codes. Note that in different series of dishwashers, the designations may differ slightly, but the essence of the problems remains similar.
| Error code | Description of the problem | Probable cause | Method of decision |
|---|---|---|---|
| E01 / F01 | Problem with the control module | Electronics failure, contact oxidation | Reboot, reset board |
| E02 / F02 | Temperature sensor error | Failure of the thermostat or wiring | Replacement of thermostat |
| E03 / F03 | Heating problem (TEN) | Scaling, tanning, tanning | Cleaning or replacing TENS |
| E04 / F04 | The water drain error | Clog, drain pump malfunction | Cleaning filters, replacing pumps |
| E05 / F05 | Water dialing error | Low pressure, valve failure. | Faucet inspection, valve replacement |
Error codes are just an indication of the search area. An accurate diagnosis is made after a physical check of these nodes with a multimeter and a visual examination.
Prevention and care of the dishwasher
To avoid the appearance of error codes and prolong the life of the technique AristonIt is necessary to carry out preventive measures regularly. The main enemy of dishwashers is scale and fatty plaque. Using quality all-in-one tablets or a separate addition of salt and rinse significantly reduces the risk of deposit formation.
Once a month, it is recommended to start the wash cycle with an empty camera, adding a special dishwasher cleaning tool or citric acid. This will help dissolve fat plugs in the tubes and refresh the internal surfaces. It is also important to empty the salt container in time, even if the indicator has not yet caught fire, especially if the water in your area is hard.
⚠️ Warning: Never use conventional cleaning products manually to wash your car camera. Abundant foam can get into electronic blocks and cause a short circuit.
Remember to clean the filters at the bottom of the camera after each wash or at least once a week. Clogged filters are the number one cause of draining errors and poor quality washing. Regular care of door seals will prevent leaks and keep the camera tight.
When it is necessary to contact a specialist
Despite the availability of information and tools, not all malfunctions can be eliminated with your own hands. If after performing all the diagnostic procedures and replacing obvious parts (filters, hoses) the error persists, the problem may lie in complex electronics.
Replacement controlFlashing the controller or repairing a direct-drive motor requires specialized equipment and knowledge. Attempting to repair complex nodes without experience can lead to an increase in the cost of recovery or complete loss of warranty (if it is still valid).
It is also worth calling the master if you find traces of corrosion on the board, the smell of burning or if the car is in a hard-to-reach place (built into the kitchen set), which requires its dismantling to access technical units. Professional diagnosis often saves time and money in the long run.
Can you operate a car with an error?
Short-term operation is possible only if the error is not related to a leak (AquaStop). Operation with a faulty TEN will lead to poor-quality washing, and with a faulty pump - to flooding. Better not take the risk.
Frequently Asked Questions (FAQ)
How to Reset an Error on an Ariston dishwasher?
To reset the error, try pressing and holding the Start/Pause button or a combination of buttons (usually indicated in the instructions, such as Rinse + Dry) for 3-5 seconds. If this does not help, completely de-energize the car by removing the plug from the socket for 15-20 minutes. This will allow the capacitors to discharge on the control board.
What does it mean to flash all the indicators at the same time?
Simultaneous flashing of all light bulbs most often indicates a critical error of the control module or a serious leak (AquaStop worked). In this case, it is necessary to block the water, turn off the device and check the pallet for water. If dry, there is a possibility of electronic failure.
Why is the machine writing an error when I just cleaned the filters?
Perhaps the debris got deeper into the system, for example, into the pipe between the pump and the tank, or jammed the impeller of the pump itself. Also, the cause may not be in the blockage, but in the electrical malfunction of the sensors or engine windings, which cannot be eliminated by cleaning.
Can I wash dishes if the error indicator is on?
Depends on the type of error. If the problem with draining or heating, a quality wash will not work. If the error is associated with the salt dispenser or rinse, the cycle can be successful, but it is better not to ignore the diagnostic signals, so as not to aggravate the situation.
Where can I find instructions for my Ariston model?
Official instructions and diagrams can be found on the manufacturer's website by entering the full model number (usually located on the end of the door or on the side wall of the camera). Also useful can be specialized forums for repairing household appliances.
