Looking at those photos again, looks like there are three settings in both PP & CP mode and it is hard to believe that a new pump is faulty, note the watts on CC2, PP2 and CP2, if the power changes then pump OK and one of those settings might be sufficient, probably CC2 or CP2 and will reduce the noise.thanks for all the replies
