ive owned this dishwasher for about 5 years,and ive never had any problems with it what so ever.
i use it a couple of times a week and find it so convenient what with the rush of day to day life nowadays,i always get great results from it,my glass ware comes out gleaming,and i find it so time saving on my oven shelves as they take ages to clean each wire on the rack.
there is a variety of temperatures to wash your dishes on,i always use the lowest as its better for the environment and bills and the results i find are the same
i always use a good quality dishwasher tablet though to ensure good results
like anything though you do need to keep the filter inside the dishwasher clean so the results stay the same and make sure the salt and rinse aid is filled up.
other than that its plain ans simple to use i would recommend this product to anyone wanting to buy their first dishwasher,you will wonder what you ever did without one!!
