Two questions: This machine has 'dry boost' - does that mean it does not have a heated dry cycle? Also can the door stay open in any position?

Hello - Thanks for taking the time to reach out. The Dry Boost feature uses a heater to help dry dishes, it's just better than a Heated Dry option. We recommend that you review the article titled: "Dishwasher - Dry Boost" on the GE Appliances website for more details about Dry Boost. The dishwasher door will not stay open in any position. At a certain open degree, the door will not hold itself in place. We hope this information helps. We're confident this unit would make a great addition to your home. Take care! -Don@GEAppliances
