i've had my gu2300xtv model for a month now.
everything was great for the first 2 weeks. i loved the ample size, the silverware in the door and the cleaning ability. it wasn't extremely quiet, but still acceptable.
suddenly, all my dishes had a white powdery film. the tech came out and told me how these units operate in order to maintain their energy star rating.
the internal heater does not kick in until the main wash. so, you have to run the tap water to the ideal temp before the unit starts. this is why the delayed timer is not useful unless you're willing to install a mini water heater...
