Ariston washing machine error codes

Ariston washing machine fault codes include:


This is a motor triac short that is generally associated with a failure of electronics or with the motor itself. This could be short-circuiting, faulty connections or contacts, or wire breakage.


A fault on the main circuit board can cause this error code to display as the signal from the tacho sensor isn’t being relayed to the electronic controller. Connections, motor windings, and tachometer windings will need investigation.


The NTC sensor which connects to the heater element may be at fault here. This part reads the temperature of the water and may fail due to defective wiring.


If the pressure switch that’s attached to the pressure hose becomes stuck this error code will show and the connection between the electronic controller and the level sensor will need to be tested as well as the pressure switch itself.


Ariston washing machine F05 code typically means that the drain pump isn’t working or that the level pressure switch has become jammed resulting in the empty tank signal not being generated after the wash programme has been completed. The drain pump will need to be checked for possible obstructions or damage, and the pressure switch for wiring and module connections.


Although this error code is rarely seen it can indicate problems with the buttons of the washing machine display. The serviceability of the buttons will need to be tested as will the connectors between the controller and the control panel


This code indicates that the heater relay has become stuck and there may be some failure of the heating circuit. All components will need to be checked with a multimeter to ensure continuity.


This code is indicating a similar issue with the heater becoming stuck in the full position. The contacts and pressure connections will all need to be thoroughly investigated.


This setup error basically means that the electronics will need to be reprogrammed or possibly replaced.


The pressure switch failure will cause this error code to display and can point toward your appliance’s inability to read the pressure sensor correctly.


This code shows that draining is an issue and the drain pump may be blocked or faulty. All connections will need to be checked alongside the impeller, windings, and coils in the pump itself.
