I had a machine about a year ago – unable to remember neff or bosch and after fitting new pump the machine pumped out water and went into spin.
Then after setting onto spin for the final test the pump didn’t work replaced pump again and still the same problem. On this machine I found that the pump would not run unless water was in the drum before setting to pump + spin.
Never heard from customer after repair – may be worth a check

The pump triac is marked K8 on the main module. Those modules are a sod to access but I think that’s your only option at least to take a look at that triac. 🙁
