Neff R4381X1GB/01 condenser drier leaks.

Neff R4381X1GB/01 condenser drier. FD8305.

Attended this machine two weeks ago – it wouldn’t fill the tank and was leaking from underneath. Cleaned out the pump reservoir, pump and condenser cavity, flushed through; water pumping into tank perfectly. The machine was leaking quite badly before: so after cleaning and to date, no faults.
It seems the leak is back: it’s very small but it is leaking nonetheless and I can’t work out what else to do as I can’t think of anything else to clean out. All the condenser seals are in good condition, the hoses are clear and the pump works well.

Any ideas?

Cheers,

Steve.
