We bought a dishwasher in Dec 2011. It worked very well for the first few washes and then started to leave white deposits on all our dishes (glass/ steel etc). We complained and a service person from IFB came home and saw the issue. He claimed the rinse aid setting was too high (which incidentally was done by the IFB person who came and installed the unit). He did not stay around after the changing the settings and asked us to run the machine for 2-3 cycles without any load. We did that and again the dishwasher worked ok - ok for a few cycles (was leaving white stains, but lesser than before).
However after a few washes, the problem has become really horrible. One entire load of dishes was spoiled with stains that are just not going away. We have tried all settings etc, but none of them seem to work. We have now stopped using the machine and would like to return it...its really that bad..
