The model is GE GLD5900. It says QuietPower 3. I just got it yesterday and I live in Tokyo, where service for US appliances is hard to come by. The Japanese gas company guy who sold it to us is a bit nonplussed as Japanese don't use dishwashers much.
OK I just started running it. It seems to be going full tilt. I opened it and although the inside is wet I don't see any water in the bottom. There's a grating but no water above the top of it.
Thank you. I'll tell the gas guy here.
