The engineer from Dixons would not install my washer/dryer because he said the hose that came with it was too short, so I need to get a longer one. He never said which hose though ?? I've looked at indesit spares online and there seem to be a few diff hoses....cold water hose, outlet hose etc ?? Do you know which hose he means to be able to connect my washer/dryer to plumbing under kitchen sink ?? Thanks
