Hi, I hope you can help!
Our Indesit DI450 stopped working last night and all the light were flashing not in any particular order! We left it until this morning and just the 3rd and 5th light were flashing at a constant rate. I have held the programme button down for 10 seconds and then they stop and we can use the dishwasher again, but after the end of the program, the 3rd and 5th light flash again!
Are you sure about the neons flashing, some machines only have four neons, on machines with seven neon lights, only neons 4 to 7 are used for fault codes.
Curious, the parts diagram for this model clearly shows a bank of 7 led’s, the same bank of led’s is used in several other machines including a couple of Hotpoint branded dishwashers. They all show seven led’s.
The fault codes for the 7 led models only use led’s 4 to 7 for the error codes. 😕
