Bought a Neff dishwasher in 2000. Now there is a loud whining noise with every cycle. Tried cleaning with descaled and checking drainage

This sounds like a bad timer. The timer is what tells the pump to drain at specified times. If it gets a bad contact, that timed cycle won't happen.

PS: Do you know for sure that the drain is occurring in mid-cycle? If not, you may just have an obstruction in the drain and/or anti-siphon valve (where the hose connects under the dishwasher.

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

Yes, bearing, most definitely. It is a cheap part but difficult to replace.
