Some programmes not working, but one is

[duffneff]

Got an old Neff dishwasher (E-Nr S4443B6GB/13) which has developed a fault.
It has three programmes - Quick (35C), Eco (50C) and Normal (65C).
Suddenly, only the quick programme is working, including heating the water.
When we try the other two programmes, we can hear water flowing and pumping out, but the dishwasher remains stone cold i.e. no water heating.
Got me puzzled big time.
Are there any suggestions as to what's going on, what's broken, please?
Thanks
Duffneff

I'm no dishwasher expert but would check the selector switch & cables to it especially if it is a ribbon cable with the controls on the door.
