Error codes for Ariston washing machines without display

It’s easy to understand what kind of malfunction a washing machine with a display alerts you to – you just need to decipher the symbol shown. When the machine is not equipped with a screen, it is more difficult to determine what is broken. The equipment stops working and begins to “blink” the indicator. To identify the cause, the housewife will have to observe the light bulbs. Let's look at the main error codes for Ariston washing machines without a display and tell you how to recognize them correctly.

Code reading principle

You can determine what kind of malfunction the washing machine is signaling by looking closely at the flashing LEDs. The process of determining the code is to determine which lights are on, whether they are on individually or together.

After observing the display on the control panel, the owner 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 “Delayed start timer” buttons (KH1), “Super wash” (KH2), “Express wash” (KH3), “Extra rinse” (KH4).

Identifying the code

Error explanations are presented in the user manual. So, by identifying which LEDs are on, it is easy to calculate the fault code. Let's figure out what the blinking of certain indicators indicates.

• KH is on Corresponds to error F01 and signals the closure of the control triac of the electric motor.
• Only KH3 lights up (error F02). The Hall sensor does not transmit signals that the motor is working properly. The drive belt may have jammed, the circuit has shorted, or the winding has broken.
• Indicators KH3 and KH4 flash (code F03).Informs about a short circuit of the thermostat or an open circuit in its circuit.
• Glow KH2 (error F4). Notifies about incorrect operation of the pressure switch. The sensor relay simultaneously signals both the fullness of the tank and its emptiness.
• Flickering KH2 and KH4 (F5). He says that after draining, the sensor relay does not signal to the controller that the tank is empty. The cause of the failure may be a failed pressure switch, a non-working pump, or a blockage in the drain system.
• Light bulbs KH2 and KH3 are burning (F6). The user's command is not recognized by the intellect, the buttons do not work correctly.
• Flashing the LEDs KH2, KH3 and KH4 (F07) simultaneously will tell you that the heating element is not heating the water to the required degree.
• The glow of KH1 (F08) indicates sticking of the heater contacts. Perhaps the heating element has failed or there are problems with its wiring.
• KH1 is lit together with KH4 (F09). It speaks of a breakdown in which a failure occurred in the volatile memory of the washing machine.
• KH1 and KH3 (F10) are flashing. Problems with the level sensor relay.
• Flickering of KH1, KH3 and KH4 (F11) indicates that no current is supplied to the pump. The probable cause is a broken wiring.
• The burning of KN1 and KN2 (F12) signals a breakdown in the connection between the “brain” of the SM and the display module.
• KN1, KH2 and KH4 (F13) indicate problems with the thermostat.
• KH1, KH2 and KH3 are lit (F14). We are talking about a malfunction of the drying heating element.
• All lamps are flashing except LED4 (F15). The dryer heater needs to be replaced.
• No indicator lights up - code F16. It can only be on “verticals”. This indicates that the drum is jammed.
• LED4 together with KH4 (F17). There is no voltage to the UBL. The washer hatch may not be closed.
• LED4 and KH3 (F18). Lost connection between the “brain” and the processor that controls the engine.

Noticing that the machine stopped working and the lights flash vigorously, don’t be alarmed.It is necessary to determine what the self-diagnosis system wants to report. Having identified the cause of the malfunction, it will be easier to repair the SMA.
