Suddenly stopping the wash cycle and flashing code on the display is always an unpleasant surprise for the hostess. If it's on your dishwasher. Hotpoint Ariston A13 error is a signal that the control system has detected a problem with the water drainage. The technique cannot complete the program because the fluid does not leave the working chamber at the required volume or speed. Often users panic, believing that burned expensive electronic module, but in most cases the problem lies in mechanical obstacles.
The A13 code (sometimes displayed as a flashing plum indicator) indicates that a water level sensor or cycle timer captures drain delay. The machine tries to pump out water, but the result is unsatisfactory. It is important to understand that ignoring this signal can lead to more serious consequences, including leakage to the floor or failure of the heating element, which can turn on in the absence of water. Therefore, diagnosis must be started immediately, moving from simple actions to complex ones.
Before you disassemble the technique or call a master, it is worth checking the basics. A blockage In the filter or hose inflection are the most common culprits of failure. In this article, we will analyze in detail the fault search algorithm, consider the device of the drain system. Ariston We will provide clear instructions for the safe removal of the blockage. Remember that a proper diagnosis will save you time and money.
Decoding of the code and the principle of operation of the drain system
Error A13 in the line of dishwashers Hotpoint Ariston and IndesitBecause the technique is often uniform, it means "water drain problem." The electronic control unit (ECU) gives a command to start the drain pump. If the water level in the tank does not drop to a critical level within a certain time (usually a few minutes), the sensor sends an error signal and the cycle is interrupted. It is a protective mechanism that prevents flooding.
The drain system consists of several key elements, each of which can cause a failure. Water passes through the filter element, then enters the compartment with drain-pump (pompo) that pushes the liquid through a corrugated hose into the sewer. On the way there may be obstacles: food residues, scale, foreign objects. The problem can also lie in the electrical part: malfunction of the pump itself or a circuit break.
Sometimes the A13 code doesn’t appear immediately, but at the end of the cycle when the machine tries to make the final dump of dirty water. In other cases, an error occurs when trying to collect a new portion of water, if the tank remained liquid from the previous cycle. Critically, if there is water in the chamber, never try to run a new washing program until you have eliminated the reason for the lock.
⚠️ Attention: Before starting any diagnostic work, be sure to disconnect the dishwasher from the power grid. Pull the plug out of the socket. Working with electrical appliances under tension is deadly. Also shut down the water tap.
Understanding how the water moves in your model Ariston LFF, LFC or LFHIt helps to localize the problem faster. Modern models use electronic control of the pump speed, which makes the system sensitive to even small clogs. If the water flow resistance is too high, the controller will read it as a malfunction and issue the code A13.
Primary diagnosis: checking external factors
The easiest and often overlooked step is to check the communications. Before removing the lids and disassembling the "innards" of the dishwasher, make sure that nothing physically interferes with it. Often the reason is banal: the hose going to the sewer, clamped with a heavy booth or twisted. Visually inspect the entire path of the drain hose. If it has bends at a sharp angle, the water current is difficult, and a powerful pump. Hotpoint Ariston It cannot handle hydraulic resistance.
The second important point is the state of the siphon shell to which the drain is connected. If the sink is clogged or the siphon has not been cleaned for a long time, the water from the dishwasher simply cannot get there, creating a reverse pressure effect. Try to disconnect the drain hose from the siphon (substituting a bucket) and start a short drain cycle. If the water goes away quickly and without error, the problem is the sewer pipe clog, not the car.
It is also worth checking the height of the connection of the drain hose. According to the technical instructions AristonThe hose should rise to a height of 40-80 cm from the floor before entering the sewer. This prevents the spontaneous drainage of water during washing and the sewage effluents from getting back into the machine. If the hose is lying on the floor, it can cause failures in the operation of level sensors.
Don’t forget the condition of the hose itself. Then, it will be a slime or a slime that will narrow the path. If the hose is many years old, it should be replaced. Check the connection to the sewer: there are often accumulated fat plugs that act as a valve, not letting water.
Cleaning filters and removing blockages in the chamber
If the external communications are in order, move to the internal filter. It's primary A13 error occurs in 80% of cases. At the bottom of the washing chamber, under the lower sprayer, there is a filtering system. It retains bones, seeds from fruits, glass and soda. If this filter is clogged, water cannot get into the pump.
The cleaning process requires care. You need to take out the bottom basket and unscrew or remove the central filter locks. In cars. Hotpoint Ariston A two-stage system is often used: a rough mesh filter and a thin flange. Take them all off. Wash thoroughly under hot water using a brush and dishwashing agent. Remove all fat and food residues.
☑️ Checklist of filter cleaning
Pay special attention to the hole under the filter. Look inside the recess where the impeller of the pump is visible. Often there are small objects: toothpicks, labels, lemon seeds. They need to be carefully removed with tweezers. Do not use sharp metal objects to avoid damaging the plastic parts or the impeller itself.
After cleaning, collect the filter in reverse order. Make sure that all the elements fall into place tightly and without distortion. A loosely closed filter can let large debris further into the system, leading to a pump jamming. Turn on the machine and start the drain program. If the A13 error disappeared, the problem was solved by a simple cleaning.
⚠️ Attention: Never operate a dishwasher without a filter installed. This will lead to a rapid failure of the drain pump and sprinklers, as well as to clog sewer pipes.
Diagnosis of drain pump (pump)
When the filters are clean and the hose is free but the A13 error persists, a drain pump malfunction is suspected. In dishwashers. Ariston circulating-pump or separate drain pumps are used. The pump may be mechanically faulty (jamming) or electrically faulty (burned winding, contact problem).
The first sign of a mechanical problem is humming. If you hear a characteristic hum or buzzing when trying to drain, but the water does not go away, then the engine is buzzing, but the impeller does not turn. Perhaps there was a shard of glass or a bone stuck between the blades. In this case, the pump is often resuscitated by getting to it and cleaning the impeller (impeller) manually.
Access to the pump in most models Hotpoint Ariston (LFF, LFC) will need to remove the lower panel of the case or put the car on its side (on a soft surface). The pump is usually located at the bottom, next to the filter. Unplug the terminals and hoses, unscrew the mounts and remove the knot. Check the rotation of the impeller with your finger - it should be free, without jamming.
How to check the pump with a multimeter?
A multimeter is needed to check the electrical integrity of the pump winding. Switch the device to resistance measurement mode (Oms). Connect the probes to the contacts of the pump connector. The normal resistance of a working winding is usually from 150 to 300 ohms. If the device shows one (infinity) or zero, the winding is burned or closed, a replacement of the unit is required.
If the impeller is rotated freely with hands, but the pump is not started from the mains, or if there is no resistance to the winding, the pump must be replaced. Repair it is usually impractical, it is easier to buy an original spare part or a quality analogue. When installing a new pump, be sure to check the condition of the sealing rubber bands to avoid leaks.
Electronics and Control Module Check
If the mechanical part and the pump are in good working order, the problem may lie in the electronics. Error A13 may occur due to a break in the wires going to the pump or a malfunction of the pump itself. electronic. In dishwashers. Ariston The control module is often located at the bottom of the body or in the basement, where humidity is high.
Moisture is the main enemy of electronics. If the car once leaked or stood in a very wet room, the contacts could oxidize, and the tracks on the board - corrode. Visually inspect the management fee. Look for traces of burns, swollen capacitors or white oxides on connectors. Sometimes it is enough to clean the contacts with alcohol and dry the fee so that the error disappears.
It is also worth checking the integrity of the wires going from module to pump. They could chew the rodents (if the car is standing on the floor in a private house) or rub themselves with vibration. Ring the chain with a multimeter. If the wire is intact but the signal to the pump does not come, the pump control simistor on the board probably burned. In this case, the module is required to be repaired by a specialist or completely replaced.
Tip: Before replacing the module, try to reset the system completely. Press the Start/Pause button or button combination (depending on the model, often indicated in the instructions) for 10-15 seconds. This will reboot the controller and may remove the software glitch.
Table of frequent causes and methods of solution
For the convenience of systematization of information, we have reduced the main reasons for the appearance of code A13 and ways to eliminate them in a single table. This will help you quickly navigate the order of action.
| Cause of A13 error | Probability. | Symptoms | Method of decision |
|---|---|---|---|
| Filter clogging | High (60%) | Water is at the bottom, there is no buzzing | Cleaning of the filter system |
| Flush hose/syphon clog | Average (20%) | Water goes slowly or stands still | Blowing or replacing the hose, cleaning the siphon |
| Flush pump malfunction | Average (15%) | No plum or silence | Cleaning the impeller or replacing the pump |
| Electronics/module failure | Low (5%) | Mistake for no apparent reason | Audit of the fee, replacement of the module |
As can be seen from the table, in the vast majority of cases, the problem is solved by mechanical cleaning without buying spare parts. However, if you are not confident in your abilities or the diagnosis indicates a complex breakdown of the electronics, it is better to contact an authorized service center. Hotpoint Ariston.
The main conclusion: 9 out of 10 cases of A13 error are solved by careful cleaning of filters and checking the drain hose. Don’t be in a hurry to change expensive parts, start with maintenance.
Prevention and proper care of the dishwasher
To make A13 error on the dishwasher Hotpoint Ariston Never bothered you again, it is important to follow the rules of operation. Regular prevention prolongs the life of the technique and provides high-quality dishwashing. Simple habits will help you avoid expensive repairs.
- 🧼 Always remove large food residues from plates before loading. Modern enzymes do not require soaking, but large pieces can clog the filter.
- 🔍 Check the filters once a month, even if the car is working normally. The fatty plaque has the property of accumulating imperceptibly.
- 💧 Use special salts for dishwashers and a rinse. This prevents the formation of scale on the heating element and the pump, which can also cause a blockage.
- 🚿 Once every 2-3 months, start the wash cycle with an empty camera, adding a special cleanser for dishwashers. This will help dissolve fat in hard-to-reach places.
Compliance with these recommendations will allow your technique Ariston serve for years. Remember that timely maintenance is cheaper than replacing nodes. If, despite all efforts, the error is returned, there may be a hidden defect or wear of the part that requires professional replacement.
Can I ignore the A13 error and continue to use the machine?
You can't ignore the mistake. If the water does not drain, the machine will not be able to draw clean water for rinsing. The dishes will remain dirty and in soapy solution. Repeated attempts to drain can overheat the pump motor, leading to its complete failure. There is also a risk of leakage if the water overflows the chamber.
Why does the A13 error only appear on long-form programs?
Longer programs (e.g., Eco or Intensive) use more water and more rinse cycles. If the throughput of the drain system is reduced (half-clogged hose or filter), on short programs the machine still manages to pump water, and on long, with a large volume, it can no longer cope, and the timer fixes the error.
How to Reset Error A13 After Resolving the Cause
Usually, it is enough to turn off the machine with the power button, wait 10-15 seconds and turn on again. In some models Ariston Press and hold the Start/Pause button or a special combination (described in the instructions) for 3-5 seconds to reset the program. If the cause is eliminated, the machine is ready to go.
