Panasonic washing macine fault codesThis set of fault codes is for the Panasonic washing machines that start with NA in the model number and the error code is displayed in the main LCD display of the washing machine.

When an error or fault is detected the on the washing machine the program will be halted and the warning buzzer will sound then the letter U or H will be displayed alternately with the error number whihc forms the fault code.

  Panasonic Washing Machines Using These Error Codes

NA-168VX2, NA-168VG2, NA-148A2, NA-128VA2, NA-147VB2, NA-16VX1, NA-16VG1, NA-14VA1

Before you start any investigation of the fault or even remove the lid of your washing machine or washer dryer 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 remember to support our site by buying Panasonic washing machine spares from our store and, if you decide that you really need a washing machine engineer please support the local washing machine repairers that help make this site possible, you can search for a local Panasonic washing machine repairer using our engineer search.

It is worth noting that at the time of writing that Pansonic spares are very hard to get indeed and that engineers have limited access to both spares and technical support. This may lead to difficulty in obtaining spare parts and also service other than from Panasonic themselves.

It is also worth pointing out that Panasonic, on this range, use spare parts that have attached connectors on them. This means that using pattern parts is not possible, you will only have the option of Panasonic spares with no alternative.

  Panasonic Washing Machine Fault Codes

These fault codes are written for washing machine repairers and not for the general public by Panasonic and they assume a certain level of competence on the part of the user in diagnostic routines. We 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 washing machine please refer to our washing machine fault finding guide from this link before you begin.

Please check that any Panasonic washing machine 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 washing machine or washer dryer. 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 Panasonic Washing Machine 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 Panasonic washing machine 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 washing machine forum after registering 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 washing machines:

      • 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.

Please 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. 

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 Panasonic washing machine or washer dryer model please post a request to confirm this in the forums.
