We have collected all the error codes of Hotpoint-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 |
|---|---|---|
| AL01, F01 | Leakage or overflow. | There was water in the pan. It is necessary: to inspect the system for tightness; check float; check the communication between the control board and the sensor. |
| AL02, F02 | Water does not flow. | Check: serviceability of the filling valve; correct connection of the drain system; whether the triac is closed on the controller board. |
| AL03, F03 | Fluid fails to drain. | It is necessary to check: all possible blockages associated with the drain system; serviceability of the drain pump, pressure switch and communication with the control unit. |
| AL04, F04 | Thermistor malfunction. | Problem within the temperature sensor: 1. Open circuit or short circuit. 2. Breakage or lack of contacts. 3. Incorrect meter connection. |
| AL05, F05 | The pressure switch is not working. | 1. Relay damage. 2. The connection of the relay with the tubes has disappeared. 3. An air lock has formed. 4. The liquid generates a large amount of foam. |
| AL06, F06 | The tank does not fill up in 150 seconds. | Causes: blockage of the inlet filter; the drain hose is not connected correctly; no water supply; solenoid valve defective; inlet hose defect. |
| AL07, F07 | Water turbine failure. | 1. Faulty: turbine or pressure switch. 2. Clogged filters, hoses, filling valve. 3. Lack of communication with the water metering turbine. |
| AL08, F08 | Insufficient water heating. | Associated with: malfunctions of the pressure switch or temperature sensor; malfunction of the electric heater (also, open circuit); control board failure. |
| AL09, F09 | Software not recognized. | The control board could not find the firmware in non-volatile memory. It is necessary to check the serviceability of the board and program it. |
| AL10, F10 | There is no communication with the electric heater. | The malfunction occurs due to: breakdown of the electric heater; failure of the control relay; communication failure between the controller board and the heater. |
