If you are doing this, and I'm not completely convinced you are, using a dishwasher is a delinquent act on so many levels.
Can you imagine the contaminants that are going to be coating all those electronic parts from using your dishwasher as a cleaning tool! The soap residues, heavy compounds (like iron, calcium, lime, etc...), small food particles, fats/oils, and other contaminants depending on the water source.
Then there is all the water that cant be dried-out because it will have worked its way inside cables, casings, connections, or even solid-state components which may have microscopic cracks from years of use, etc... All of that will cause corrosion, plastic breakdown, short-out parts, etc...
That isn't all! There is the act of putting electronic items in the same place you clean your dishes! There are so many chemicals used on electronics that are hazardous to you, your family, the local community, and the environment. It really disturbs me that you would be so careless that you knowingly and callously allow dangerous compounds to come into contact with items you and your family use around and on food!
Many compounds on electronics are deadly or create highly debilitating conditions. Do the people in your household have any idea the situation you are creating for them? You said that you are drying the parts on your bed. So without a doubt this is your dishwasher at home, do you have no concern for yourself or anyone who uses this dishwasher?
What about your local community, do you think they want you getting all that stuff in their water? And you say that you have been doing this for over a year on your own computers and also on your "clients" machines! Do they know that you are doing this and the situation you are creating?!
I truly hope you are just making this up and that all this was just to gather some attention here. But if you are actually doing this, stop. Any argument that you could use to justify doing this would be erroneous. I can NOT believe what I have read; and I also believe that what you are doing is absolutely reprehensible.
