Yeah it's tricky isn't it, I guess if you're cooking with a new kitchen tool, in this case a dishwasher, I think it's reasonable to say it may take little while to figure out that exact combo of safe and perfectly cooked. I think my recommendation to you would be when you're cooking in the dishwasher err on the side of safety. The maybe experiment from there, perhaps a lemon dishwasher tablet would add a zing.
