Ariston dishwasher error codes

Ariston dishwasher error codes The owner of an Ariston dishwasher may encounter a system error that will interfere with the operation of the equipment. This error is not necessarily caused by a serious malfunction; most often you can cope with the problem on your own.

The main thing is to correctly recognize and decipher error codes and take the right measures to eliminate the malfunctions that caused them. How to do this, let's answer this question in the article.

Self-diagnosis of Ariston dishwashers

The Ariston dishwasher, like any other, has a self-diagnosis system. The operation of this system comes down to recognizing various faults. As soon as the control module of the dishwasher detects a malfunction, it immediately stops the operation of the equipment and generates an error with the corresponding code. The user or specialist, before starting repairs, needs to understand what malfunctions the dishwasher implies by issuing the appropriate code. Let's look at the error codes for Ariston dishwashers.

Error code A 01. Found on most Indesit and Ariston dishwashers. This error means that a leak has occurred somewhere and the Aqua Stop system has activated.
Error codes A 02, A 05, A 12. They mean that the water in the Ariston dishwasher does not heat up to the temperature set by the program. There can be many reasons for this: the heating element burned out, the control module failed, the wiring in the electrical circuit is faulty. And 05 tells us that there is no signal from the heating element sensor.
Error codes A 03, A 04. They tell us about problems with blockages. In this case, error A 03 indicates a blockage in the drain system.Reasons: the drain hose, pipe or pump is clogged. Error A 04 indicates that there is a blockage in the water inlet system. Reasons: inlet hose, valve, filter clogged.
Error code A 06. Problems with the power supply to the filling valve. Reasons: the terminals of the filler valve are burnt, the electrical wiring is broken, the control module is faulty.
Error codes A 07, A 08 and A 09. This is one of the most serious errors indicating a breakdown of the circulation pump or control unit.
Error code A 10. In some models of Hotpoint-Ariston dishwashers, this error indicates problems with the heating element, but the main reason lies in the electrics of the inlet valve.
Error code A 11. This error occurs in cases where, for some reason, power is not supplied to the circulation pump motor, or it is simply jammed by a foreign object that has gotten there.
Error code A 13. Most often, this error occurs when the valve of the detergent cuvette cannot open and the tablet does not dissolve. The most common reason: improperly stacked dishes.
Error code A 14. There are problems with draining waste water. Most often, the error occurs when the drain hose is not connected correctly and water from the sewer pipe goes back into the dishwasher.

How to fix errors yourself?

This question cannot be answered in detail in one article, rather it is a topic for an entire book, so we will talk about errors and their correction in an overview so that you get a general idea of how to eliminate them. We simply will not consider those faults that you should not try to fix yourself.

The cause of error A 01 can be easily eliminated with your own hands.The course of action will depend on where the leak occurred in the machine body or hose. If a leak occurs in the Aqua Stop hose, then you need to perform a number of actions described in detail in the article Aqua stop hose for dishwasher.

Note! If a leak has formed in the housing, you will have to disassemble the dishwasher and look for the location of the damage, repair it, and then restart the machine. If you simply drain the pan and then deactivate the sensor, the problem will occur again.

Experts are skeptical about errors A 02, A 05, A 12, saying that it is very difficult to eliminate them with your own hands, since even offhand you can name 11 reasons for their occurrence. Indeed, before you climb into the car body, adequately assess your skills and abilities, it is better to contact a specialist. But if you are confident with a multimeter, you can measure the resistance of the heating element and thermistor; perhaps the problem is in the electrics and one of the spare parts needs to be replaced.

Errors A 03, A 04 of Ariston dishwashers occur if the user does not properly care for his “iron assistant” and does not clean the filters on time. What happens in this case? If a surface clog occurs, dirt can go deeper and clog the pipes and drain hose. You need to do the following: Carry out preventive cleaning of the machine using special chemicals once every 3 months, and clean it manually at least once every 6 months.

To eliminate error A 06 you will have to check with a multimeter and clean the intake valve contacts, there is a 99% chance that this is the problem. In other cases, wires or even a control module. To get to the fill valve you will have to partially disassemble the car.Errors A 07, A 08, A 09 are, in principle, difficult to eliminate with your own hands, so we will not talk about them; if they occur, immediately turn off the dishwasher and contact a qualified technician. Prepare for the fact that repairs can cost $110 or more.

You can try to fix error A 11 yourself. You will have to do the following:

place the dishwasher on the back wall;
dismantle the pallet;
disconnect the circulation unit from the power supply, pull it out, disassemble it;
clean it inside, remove all foreign objects;
collect everything and put it in place.

Important! If error A 11 occurs, physical cleaning will help; chemical cleaning is useless in this case.

Error A 13 can be resolved very simply, you need to thoroughly clean and rinse the detergent drawer, paying special attention to the valve, then put the dishes in the baskets correctly, as indicated in the instructions, and only then restart the dishwasher. Error A 14 in the vast majority of cases occurs in dishwashers that have either just been installed, or no more than 3 months have passed since installation. The problem is solved by correctly connecting the drain hose to the sewer. How to do this, read the article How to connect a dishwasher to water supply and sewerage?

To summarize, we note that many users of Ariston dishwashers consider system errors to be a big problem, because the “iron assistant” stops and stops washing dishes. In fact, the self-diagnosis system saves your dishwasher from costly repairs, because if a minor malfunction is not immediately corrected, it will quickly turn into a serious one.
