The average Dishwasher should be expected to last anywhere between seven and twelve years, with the average working expectancy to be approximately ten years. Factors like care, maintenance, and frequency of usage, as well as the quality and the brand of the dishwasher will affect the life expectancy and frequency of dishwasher repair.
If you want to buy a dishwasher the best time of the year to do this is in and September and October. That is when the appliance manufacturers usually reveal their new lines, which means that the older models will usually go on sale during this time.
Another great time for appliances buying is on the holidays: Labor Day in September, Veterans Day and Thanksgiving and Black Friday during November and also often on the Fourth of July.
