Problem with my Zanussi ZSF 4112 dishwasher?
The machine is working fine but we frequently get jet black greasy/rubbery spots and streaks on the crockery. There also is a lot of spots in the filters although we clean them regularly. Only white spirit seems to clean the spots/streaks, soapy water will not clean them off satisfactorily. There are no other problems with the machine.
