We have collected all the error codes of Ariston dishwashers with a detailed description of the causes of malfunctions, diagnostics and repair. For convenience, arranged in a convenient and understandable table below.
The models with the display show the alphanumeric combination on your display, find it in the table and find out the reason for the error.
Models without a display do not execute the specified program and according to the lit or flashing lights placed on the control panel, you can find out the problem.
|Error code||Description||Causes and solution|
|A01||The "Aquastop" function is activated.||The water supply stops. This is due to water leakage, it accumulates in the pan, raises the float, which presses the button and the leakage protection is triggered. Visually inspect the dishwasher for leaks. Check the wiring for integrity, test the pressure regulator. If you cannot do it yourself, call the service.|
|A02||No heating.||There is no water heating. The heating element or thermal sensor is malfunctioning. The cause of the breakdown could be a short circuit in the network or greasy contacts. It is important to correctly diagnose the equipment in order to identify the faulty one: relay, thermostat, thermistor, regulator. Replace the burnt part with a new one.|
|A03||Thermistor failure/drain blocked.||Most often, the system works when the hoses are loose. Or the thermistor has failed, the adjacent wires have gone. Carry out diagnostics of the thermistor, for this, contact the service center. You can independently inspect the hose attachment points and reattach them.|
|A04||Faulty tubular electric heater.||The water does not heat up or it passes very slowly. In the specified modes, the liquid does not reach the required temperature within the specified time and the operation is blocked. Inspect the heater for integrity. If defects or damage are found, replace in detail with a new one. You can do it yourself or at a service center.|
|A05||The drain system has failed.||At the end of washing dishes, the waste liquid does not drain. Dirty water always remains inside because of this, the dishes are dirty and the dryer does not work. Inspect the drain tube and filter, they may be clogged with grease and food debris. If everything is clean, call the wizard to diagnose the blocking system, the contacts may be damaged.|
|A06||Water intake does not occur when turned on.||When turned on, water is not drawn or the set is too slow, does not reach the desired level. Because of this, the machine does not work correctly or does not work at all. Check the water supply faucet, whether it is well open. The hose may be kinked or the pipes damaged. Run wiring diagnostics and make sure that all signals to the sensors are received.|
|A07||The motor and its controls are out of order.||The reason may be the recirculation pump jamming due to natural wear, assembly defects, incorrect operation mode. The motor burned out due to a short circuit. It is impossible to independently diagnose and inspect. Call a certified repairman to fix defects. Before his arrival, do not turn on the equipment.|
|A08||Auxiliary pump failed.||Depressurization, violation in the selection of the operating mode of the sink disabled the pump. The circuit or contacts of the control module may be broken. Therefore, the equipment does not work and does not start. Diagnose the drain system. It is important to inspect all elements for wear and defects. Inspect the control module to make sure it does not require replacement. Call a specialist.|
|A09||The main pump is not working.||There were problems in the operation of the motor and the main pump due to natural wear. The control node or its components may also have been damaged. Clogged filters and pump. First of all, it is important to inspect the pump with filters and clean them if necessary. If after that there was no start. Call in a repair technician.|
|A10||The triac solenoid has failed.||In some models, it indicates problems with heating. It can also report a breakdown of the main board. Reasons: defect on the valve, short circuit. Examine the intake valve, relay. You also need to ring the wiring and diagnose the control panel. Contact the masters from the service, they will identify the defect and fix it.|
|A11||Triac solenoid broken.||Possible reasons: problems with wiring, a foreign object got into the blades of the recirculator and it got stuck. It is possible that the main board is blocked. A repair technician is needed to fully diagnose valves, relays, wiring, and controls. If the equipment is available, weaknesses can be identified and repaired.|
|A12||The tube heater relay has failed.||Most likely there was a short circuit that damaged the water heating system. Because of this, the tubular heater does not work. Washing is not working correctly. In this case, it is necessary to inspect and diagnose the heating system and the thermal relay. The water heating element needs to be replaced. It is carried out by a specialist from the service department.|
|A13||Dispenser problem.||Because of this defect, the water does not heat up. Also, the detergent tablet is not thrown away. The dishes remain dirty after washing, the machine may not start at all. To get rid of this defect, it is enough to clean the solenoid and the dispenser well. After that, restart the device. The failure is no longer shown on the display.|
|H2O||No water is drawn.||Water intake is very slow, with stops or does not occur at all for several reasons: the pressure in the tube is too low, there is a defect on the valve. Check the pressure in the hydraulic system. It is also important to inspect the valve for integrity and the inlet hose. If the breakdown remains, you need to call the service and check the wiring.|
