Fault codes, also called error codes or fault codes, allow your device to automatically report an internal malfunction. Below you will find the list of fault codes for your Ariston dishwasher and their meaning: this will give you an indication to best diagnose the origin of the malfunction of your appliance and identify the faulty component.
The error code can be read directly on the front panel of your Ariston dishwasher. Depending on the model, you can read this code on a display (for example, “Err 01”) or by observing the number of LED flashes (for example: 4 LED flashes = “Err 04”).
Refer to the user manual for your Ariston device to find out the exact meaning of the fault code displayed or the lights that flash. The number of flashes often corresponds to the error code number, but there are specificities linked to each model and brand.
The fault codes stored in the memory of the Ariston dishwasher can be erased by pressing and holding the start pause button for 5 seconds. The device can then restart its cycle normally.
ERROR CODE E1 – LEAK OR OVERFLOW
This trouble code indicates a leak or overflow from your dishwasher. For that:
- Check if the dishwasher pressure switch is defective. This spare part is used to check the level or presence of water in the machine.
- Check the compression chamber. The compression chamber is a switch operated by pressurized air. The water in the tank compresses air in this chamber. This air is sent to the pressure switch. If the compression chamber fails, some parts may think there is a leak in the dishwasher when there is nothing.
- If there are no leaks, check the dishwasher’s leak detector . In fact, the latter may be faulty.
This fault code indicates that your dishwasher is filling for no reason . For that:
- First check the solenoid valve . In fact, this part allows you to authorize or interrupt the circulation of water. It works like an electric faucet. If your appliance fills for no reason, check to see if this electric faucet is faulty. If you are replacing the solenoid valve in your dishwasher, it must be replaced with a compatible model.
- Check the dishwasher’s compression chamber. The compression chamber is a switch operated by pressurized air. The water in the tank compresses air in this chamber. This air is sent to the pressure switch. If the compression chamber fails, some parts may think there is a leak in the dishwasher when there is nothing.
- Check the pressure switch. This part is used to control the level or presence of water in the machine.
This trouble code indicates a draining problem in your dishwasher . For that:
- Check that the solenoid valve filter and pump filter are clean.
- Check that no residue is blocking the drain inlet, located at the very bottom of the dishwasher.
- Check your dishwasher’s compression chamber and pressure switch.
ERROR CODE E4 – TEMPERATURE PROBE
This trouble code indicates a problem with the temperature sensor in your dishwasher. The dishwasher temperature sensor (CTN type) is simply used to control the temperature inside your appliance. An exchange of information takes place between the temperature probe and the programmer of your device.
This small rod is located under the filter which comes out at the front right of the hydraulic block. Test the value of the probe with the ohmmeter (58 kilo-ohms at 20°C, 12 kilo-ohms at 60°C.) and its connections.
ERROR CODE E5 – WATER LEVEL
This fault code indicates a water level detection problem in your device. The dishwasher is filling, but the level is not detected.
- Check the compression chamber. The compression chamber is a switch operated by pressurized air. The water in the tank compresses air in this chamber. This air is sent to the pressure switch. If the compression chamber fails, some parts may think there is a leak in the dishwasher when there is nothing.
- Check the pressure switch. This part is used to control the level or presence of water in the machine.
ERROR CODE E6 – WATER DETECTION
This fault code indicates a water detection problem in your device.
Slowly turn the programmer by hand, notch by notch. The machine still won’t take water, but if you hear the drain pump running, this shows the power supply is good.
Then check:
- The solenoid valve : The solenoid valve allows or interrupts the circulation of water. It works like an electric faucet.
- The pressure switch : This part is used to control the level or presence of water in the machine.
- The condition of the wiring of the solenoid valve circuit (cut at the hinge)
- The programmer contact controlling the solenoid valve (very rare failure)
- The filling float
ERROR CODE E7 – WATER DETECTION
This fault code indicates a water detection problem in your device. Water is clearly seen in the machine, but is not detected for propulsion in the wash arms.
- The cycling pump sends water into the spray arms and recycles the wash water. Then check its general condition, its turbine and its windings. If it malfunctions, your dishwasher’s cycling pump must be replaced.
- At the same time, check the pressure detector of your device. The latter can be lacking and transmit bad pressure.
ERROR CODE E8 – WATER HEATING
This fault code indicates that the water is not heating in the device. For that:
- Check the resistance of the dishwasher if it is not out of order. The main role of the resistance is to heat the water in your dishwasher. In the event of a malfunction, this part must be replaced.
- Also check the temperature sensor. In fact, the latter may fail and transmit a bad result to the device’s control board.
ERROR CODE E9 – ELECTRONIC CONFIGURATION
This fault code indicates an electronic configuration problem in your device. Replace the electronic board or try reprogramming the dishwasher.
ERROR CODE E10 – WATER HEATING
This fault code indicates that the water is not heating in the device.
Check the resistance . The main role of the resistance is to heat the water in your dishwasher. Replace this part if it is faulty.
ERROR CODE E11 – CYCLING
This fault code indicates a cycling problem in your device.
The cycling pump sends water into the spray arms and recycles the wash water. Then check this part, as well as its connections and its pump turbine.
ERROR CODE E12 – COMMUNICATION
This trouble code indicates a communication problem between the display and power board in your device.
Check the connections and the general condition of the two cards. Replace the power board if it is defective.
ERROR CODE E13 – POWER CARD
This fault code indicates that the power board is missing in your dishwasher. Replace the card. It is this part that manages and processes the data on the device.
