Ariston Dishwasher Error Codes

Ariston dishwasher error codes An Ariston dishwasher owner may encounter a system error that prevents the appliance from operating properly. This error doesn't necessarily indicate a serious malfunction; most often, the problem can be resolved independently.

The key is to correctly recognize and decipher error codes and take the appropriate steps to troubleshoot the underlying issues. Let's find out how to do this in this article.

Self-diagnosis of Ariston dishwashers

The Ariston dishwasher, like any other, has a self-diagnostic system. This system recognizes various faults. As soon as the dishwasher's control module detects a fault, it immediately stops operation and displays an error code. Before beginning repairs, the user or a technician must understand the faults indicated by the corresponding error code. Let's look at the error codes for Ariston dishwashers.

Error code A01. Occurs on most Indesit and Ariston dishwashers. This error indicates a leak somewhere and the Aqua Stop system has been activated.
Error codes A02, A05, and A12 indicate that the water in your Ariston dishwasher isn't heating up to the set temperature. There could be many possible causes: a burned-out heating element, a faulty control module, or faulty wiring in the electrical circuit. A05 indicates that the signal from the heating element sensor isn't being received.
Error codes A03 and A04 indicate problems with clogs. In this case, error A03 indicates a clog in the drain system. Causes: a clogged drain hose, pipe, or pump. Error A 04 indicates that there is a blockage in the water inlet system. Reasons: the inlet hose, valve, or filter is clogged.
Error code A06. Inlet valve power supply problems. Causes: burnt inlet valve terminals, broken wiring, faulty control module.
Error codes A 07, A 08, and A 09. This is one of the most serious errors indicating a failure of the circulation pump or control unit.
Error code A 10. In some Hotpoint-Ariston dishwasher models, this error indicates a problem with the heating element, but the most common cause is an electrical problem with the inlet valve.
Error code A 11. This error occurs when, for some reason, power is not supplied to the circulation pump motor, or it is simply jammed due to a foreign object getting inside.
Error code A 13. This error most often occurs when the detergent drawer valve fails to open and the tablet does not dissolve. The most common reason: incorrectly stacked dishes.
Error code A14. There is a problem with the wastewater drainage. This error most often occurs when the drain hose is incorrectly connected, causing water from the sewer pipe to flow back into the dishwasher.

How to fix errors yourself?

This question can't be answered in detail in a single article; it's more of a book-length topic. Therefore, we'll cover errors and their fixes in a general overview to give you a general idea of how to resolve them. We won't cover any issues that shouldn't be attempted on your own.

The cause of error A01 can easily be fixed at home. The procedure will depend on where the leak is located in the machine body or hose. If the leak is in the Aqua Stop hose, you must follow the steps detailed in the article. Aqua Stop Dishwasher Hose.

Please note! If the leak is in the housing, you'll need to disassemble the dishwasher, locate the damage, repair it, and then restart the machine. If you simply drain the water from the tray and then deactivate the sensor, the problem will reoccur.

Experts are skeptical about errors A 02, A 05, A 12, saying that it is very difficult to fix them yourself, since even off the top of my head, I can name 11 reasons for their occurrence. Indeed, before you climb into the body of a car, adequately assess your skills and abilities; it is better to consult a specialist. But if you're confident with a multimeter, you can measure the resistance of the heating element and thermistor. It's possible the problem is electrical and one of the parts needs to be replaced.

Errors A03 and A04 in Ariston dishwashers occur if the user doesn't properly maintain their dishwasher and doesn't clean the filters regularly. What happens in this case? If a surface blockage occurs, the dirt can penetrate deeper and clog the pipes and drain hose. Here's what to do: Perform preventative cleaning of the machine using special chemicals once every 3 months, and clean it manually at least once every 6 months.

To fix error A06, you'll need to check the inlet valve contacts with a multimeter and clean them; there's a 99% chance this is the problem. In other cases, the problem could be the wires or even the control module. Accessing the inlet valve will require partial disassembly of the machine. Errors A07, A08, and A09 are generally difficult to fix yourself, so we won't discuss them here. If they occur, immediately unplug the dishwasher and contact a qualified technician. Expect repairs to cost $110 or more.

You can try to fix error A11 yourself. Here's what you'll need to do:

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

Important! If error A11 occurs, physical cleaning is the only solution; chemical cleaning is useless in this case.

Error A13 is very easy to fix: thoroughly clean and rinse the detergent drawer, paying particular attention to the valve, then load the dishes into the baskets correctly, as indicated in the instructions, and then restart the dishwasher. Error A 14 in the overwhelming majority of cases occurs in dishwashers that have either just been installed or less than 3 months have passed since installation. The problem can be solved by properly connecting the drain hose to the sewer. Learn how in this article. How to connect a dishwasher to the water supply and sewerage system?

In conclusion, many Ariston dishwasher users consider system errors a major problem, as their "iron helper" stops washing dishes. In fact, the self-diagnostic system protects your dishwasher from costly repairs, because if a minor issue isn't addressed immediately, it can quickly become a major one.
