Hello!
The dishwasher beeps four times when the cycle is completed, it does it since the very beginning. I have no idea if it's how it's supposed to be or not, cause there is no explanation about the audio signals in the manaul. Last time (maybe it was the 5th cycle of the machine overall) it beeped twice more after a while. Seems like a some kind of fault code, but it's impossible to identify.
Maybe somebody could help - thank you very much!
