If your dishwasher leaves behind a whitish residue on your dishes, it may only mean that its drainage system is likely clogged. Take out the filter and clean it out. You would often observe a disconnect in how its door closes, if the dishwasher is faulty. Regardless of what the problem might be with that noisy dishwasher, it can be easily fixed. Note that people often wrongly assume that the dishwasher’s timer is the problem. Remove the screws connecting the bracket and its associated valve.
