it means theres an eprom/setup error
the main comtrol board has a microprocessor, which stores the program file the machine uses, and its now corrupt
indesit, being themselves are the only people who can re-program the original eprom with their own software, they do not make it available the independant traders , or the public at large
for urselves and the traders, a replacement pcb is available, and it will need a programmed eprom or smartcard, and its not cheap
ring indesit and mention its only just over a year old, i guarantee theyll be completely useless, will do nothing to help you except offer you a fixed price repair @ £99 then proceed to flog you a warranty you shouldnt need
your gonna end up paying twice for that machine
good luck
