Fault or error codes apply to an the Ariston DV, LS and LSV range of dishwasher models manufactured by the Indesit Company. The fault codes listed here will also apply to models from around 2004 from Philco, Ariston and Indesit as well as possibly some Hotpoint dishwashers as they are all Indesit Company owned brands.

Before you start any investigation of the fault or even remove the lid of the dishwasher please read and fully understand this article in full and pay particular attention to the safety and information notices at the bottom of this page as they contain extremely important information!

Please try to support our site by buying Ariston dishwasher spares from our store here and, if you decide that you really need an engineer please support the local repairers that help make this site possible, you can find a local dishwasher repair engineer using our engineer search facility.

Ariston Dishwasher Fault Codes

These fault codes are written for dishwasher repairers and not for the general public by Indesit and they assume a certain level of competence on the part of the user in diagnostic routines. We may have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits. For more help and advice on fault finding on a dishwasher please refer to our dishwasher fault finding guide from this link before you begin.

Please check that any Ariston dishwasher spares recommended are suitable for use on your particular model and serial number. If you are unsure about the suitability of any spare part please ask to ensure that you get the correct spares for your particular dishwasher model. Please, don't guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.

More Ariston Dishwasher Help, Advice And Guidance

Should you need more help and guidance please use the links from this article as most of them will help you to understand your dishwasher a lot better and probably very much help you in diagnosing the fault you have. Of course there are many other articles on the site that will also help you do this.

In addition you can post in our dishwasher forum but please do pay heed to the information below before doing so and read the guides, they are there to help you.

You must understand certain things before you begin or attempt any repairs on your own and we want to make these points very, very clear to anyone that decides to investigate one of these or any other dishwashers:

  • We are not responsible for your safety, you are and by using this guide you accept that and accept that any damage that you may cause and work undertaken is entirely at your own risk.
  • We will advise the common causes of the fault codes but we cannot guarantee that any parts or work recommended will resolve the issue. It is entirely your responsibility to diagnose your particular problem and resolve it.
  • We are not responsible for you buying spares that do not resolve the problem, this is down to your own diagnosis not ours.
  • No warranty is inferred, implied or given.
You also have to understand that fault or error codes are not a "magic bullet", they will not tell you what the problem is, they will only offer you an indication of where the problem lies and they are no substitute for good old fashioned diagnostic skills. You can find out more about what fault codes actually tell you in this article. So please be well aware that, even with this new found knowledge you will still have to actually be capable of investigating and diagnosing the problem and this means adhering to basic appliance safety for working on them. As, if you don't and tell the engineers in the forums that you hooked up components to a live feed, worked on a live appliance and so on they will be a whole heap less willing to help you in our dishwasher forum because they will assume that you are not safe working on your dishwasher.

Please do note that manufacturers can and do change fault codes without notice and we cannot guarantee that these error codes will apply to your particular model as all codes apply to a wide range of appliances and not normally any one specific model. To determine if these fault codes do apply to your particular Ariston dishwasher model please post a request to confirm this in the forums.

Applies To Dishwasher Models

Please note that we cannot guarantee that these fault codes will apply to every model listed as there is no list produced on what fualt code relates to which particular dishwasher models. Yoou have to work out the range and electronic control system used as well as the error or fault signalling system being used on that particular dishwasher.
