This set of fault codes only pertains to the ISE555WH but it may also relate to Beko models that use the same PCB from Invensys for a controller and have the three LEDs for wash, ready and spin used.
These fault codes are displayed by way of blinking or flashing light on the front of the washing machine. Fault codes are displayed on the LED’s as shown above and are coded, in brackets, after each code to indicate the LED’s that will be lit where 1 = on and 0 = off. So for H1 for example, the “Ready” LED will be on whilst the “Wash” and “Spin” will both be off.
Please remember to support our site by buying spares from our spare part 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 search for a repairer from this link.
These fault codes are written for washing machine repairers and not for the general public by ISE 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 basic fault finding guide from this link before you begin.
Please check that any ISE 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. 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.

ISE do make pains to point out the following on their fault code information:
PS : THE ERROR CODES GIVEN ABOVE DOES NOT ALWAYS MEAN REASON FOR THE FAILURE IS THE DEFINED COMPONENT
ALWAYS CHECK THE CONNECTORS AND WIRING FIRST TO SEE IF THE CAUSE OF THE FAILURE IS A DISCONNECTION OR SOMETHING SIMILAR.
After entering the failure code observing mode, pressing and holding “Run/ Pause/Cancel” button for a short time will erase the error code from the memory. After you complete your inspection, if you are not sure that you have solved the problem and if you are going to change the electronic card group, do not erase the error code so that we may investigate any failures.
For all other cases, you may erase the error code.
Should you need more help and guidance please use the links from this article as most of them will help you to understand your ISE 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 help and advice forums 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:
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 ISE washing machine model please post a request to confirm this in the forums.
Buying spare parts for any washing machine or getting a service engineer can range from the simplest task in the world to one of the most daunting as you try to pick your way through model numbers, serial numbers, ranges and all sorts of information. We try to make this as simple as possible for you and take out any hassle but, sometimes, we know that we all need a little help from the experts.
