Error codes for Ariston washing machines without a display

Understanding the malfunction a washing machine with a display is simple – you just need to decipher the symbol displayed. When a machine doesn't have a display, determining what's wrong is more difficult. The machine stops working and starts flashing its indicator lights. To determine the cause, you'll need to observe the lights. We'll look at the main error codes for Ariston washing machines without a display and explain how to recognize them correctly.

The principle of reading the code

You can determine the specific fault your washing machine is signaling by closely examining the flashing LEDs. The process of identifying the code involves identifying which lights are illuminated, whether they are illuminated individually or together.

By observing the indication on the control panel, the housewife will accurately determine the error.

Next, you need to figure out which indicators correspond to which fault code. In SMA Ariston error must be identified by the blinking of the “Spin” LED (LED 4) and the "Delayed start timer" buttons (KH1), "Super Wash" (KH2), "Express wash" (KH3), "Extra Rinse" (KH4).

Identifying the code

Error codes are deciphered in the user manual. By identifying which LEDs are lit, it's easy to determine the error code. Let's look at what the blinking indicators mean.

• KH is on. Corresponds to error F01 and signals that the electric motor control thyristor is short-circuited.
• Only KH3 (error F02) is lit. The Hall sensor isn't transmitting signals indicating the motor is working properly. The drive belt may be jammed, the circuit may be shorted, or the winding may be broken.
• The KH3 and KH4 indicators are flashing (code F03). This indicates a short circuit in the thermostat or an open circuit.
• KH2 light (error F4) indicates a malfunction of the pressure switch. The sensor relay simultaneously signals both full and empty fuel tanks.
• KN2 and KN4 (F5) are flickering. This indicates that after draining, the sensor relay is not signaling the controller that the tank is empty. This could be caused by a faulty pressure switch, a malfunctioning pump, or a blockage in the drain system.
• The KN2 and KN3 (F6) lights are on. The user command was not recognized by the intelligence, and the buttons do not function correctly.
• The simultaneous flashing of LEDs KN2, KN3 and KN4 (F07) will indicate that the heating element is not heating the water to the required temperature.
• The KN1 (F08) light indicates that the heater contacts are sticking. The heating element may be faulty or there may be a problem with its wiring.
• KN1 and KN4 (F09) are lit. This indicates a malfunction involving a failure in the washing machine's volatile memory.
• KN1 and KN3 (F10) are flashing. There is a problem with the level sensor relay.
• Flickering of KN1, KN3, and KN4 (F11) indicates that there is no current being supplied to the pump. A likely cause is a broken wire.
• The lighting of KN1 and KN2 (F12) signals a break in the connection between the CM “brain” and the indicator module.
• KN1, KN2 and KN4 (F13) indicate problems with the thermostat.
• KN1, KN2, and KN3 (F14) are lit. This indicates a faulty dryer heating element.
• All lights are blinking except LED4 (F15). The dryer heater needs to be replaced.
• No indicator lights – code F16. This only happens on vertical washers. This indicates that the drum is jammed.
• LED4 along with KN4 (F17). No power to the door lock. The door may not be closed.
• LED4 and KN3 (F18). Communication failure between the "brain" and the processor controlling the engine.

Noticing that the machine stopped working If the lights are flashing vigorously, don't be alarmed. You need to determine what the self-diagnosis system is trying to tell you. Once you've identified the cause of the malfunction, repairing the washing machine will be easier.
