We receive loads of enquiries in the washing machine forum about washing machines from Ariston, Indesit and Hotpoint where the reported problem is that the control dial on the washing machine just turns around and around, lights, lamps or an LED will flash but the washing machine will sit and do nothing.
This is an indication that a fault has occurred on the wash cycle and the machine is displaying an error code to indicate what the problem could be. It is true to say however that, whilst this is an indication of the nature of the fault, it will not like almost any fault code, tell you exactly what the fault is or what actual component is faulty.
The light will flash in a sequence giving a number of flashes, pause, then repeat the sequence and continue to do this until the problem is resolved. To get a full list of the fault codes please see this article for all the fault codes.
As you will see there can be no less than eighteen possible codes that can be displayed and al can be thrown up by various issues that the washing machine can detect. The article linked to above also gives the most common reasons for each fault code to be displayed.
However, it is the experience of the field engineers that not only can the components be at fault and give rise to these error codes being displayed but that the electronic controls themselves can also go faulty causing errant error codes to be thrown up. This is not usually the case but, it can happen.
Opinion On Indesit, Hotpoint & Ariston Washing Machines
The engineers in general do not rate the electronics in these machines with them, at best, being described as problematic.
Many of the newer washing machine and washer dryer models also required to be "programmed" with the correct software for which you require either an EMIT laptop that is only available to Indesit Company engineers or, you need to have a card reader/writer that it exclusive to Indesit.
You will see websites selling these washing machine electronic control modules but be aware that you cannot replace many of them yourself without a programmer, hence we ask people to contact us so that we can advise accordingly.
