Hello, Can you tell me how many times the LED flashes before taking a pause to start flashing again?
Are there any other LEDs that are lit on the panel?
Use the following diagram to indicate which LEDs
That looks to be a fault with the power to the dishwasher (PCB)
Personally, if you do not know about how to repair/replace parts I would not attempt it yourself...
If you pass me your postcode I can see if I have any engineer information for your area.
I would wait.. The part can be ordered once diagnosis is confirmed. It may be the PCB, but it may be that the PCB is not getting full power from the mains supply. The PCB itself may be ok.
Notwithstanding this, the engineer can get the parts cheaper than you can.
