siemens washing machine programs problem
 

I have a SIEMENS SIWAMAT WXL 1460FF washing machine, bought in 2004, that
function correctly only on 2 programs, wool cold water and 30°C silk. All
others programs have the same problem: the machine DO NOT HEAT THE WATER,
and remains indefinitely on washing, do not rinse. It is not a heating
resistor failure (heat water on program 30°C silk) and not a pump problem
(empty correctly the cuve with the 2 correct programs). It seem me there is
no hardware failure, it is probably a logical error in the command module
(electronic programmer)
Does somebody know how to make a factory reset of the programmer? on some
machines there is a hidden service menu accessed by pressing some switches
together when powering on. Thank you for your help, not to throw away in
garbage a machine that only neet a logical reset
