The warranty rate is calculated as the share of products reported faulty within the Grundfos two-year warranty period. To compensate for time on stock and transport the sold amount is displaced three months back in time compared to registered warranty cases.
The figures show that Grundfos succeeds in further reducing the faulty rate. The faulty rate was 0,61% in 2009, 0,48% in 2010 and 0,46% in 2011. The target for 2012 is a maximum faulty rate at 0,43%.
