Hi. This appliance fills then gives a repeated clicking sound a little bit like a relay clicking rapidly in and out but it doesnt sound as though its coming from pcb. Main pump seems to be running slowly and therefore not washing. Looked on quickfinder and noticed modified heat pump and loom for this model. Not repairing myself but wondered if this modification could relate to this fault, if any of the Neff/ Bosch guys could advise. Thanks.
