ChiSue, The drain hoses flex every time the drawers are opened/closed but there's no immediate concern unless they're leaking. They're designed to be flexible but cracking at some point of aging is a fairly common thing. The fill hoses also flex but they're more of a stretchy/rubbery material than the drain hoses. My lower drawer drain hose had a crack a few inches behind the drawer. Both had cracks where they exit behind the unit and made a sharp turn toward the left through the cabinetry partition. Impossible to see back there when the unit is in place so I have no idea how much bend is in effect on the new hoses. :-| KA discontinued drawer dishwashers a few years ago. The only brand currently on the US market is F&P, and possibly DCS (which is owned by F&P). I considered updating to the latest model (tall upper drawer!) and the racking is more adjustable now ... but decided to fix the DD603.

Question for @dadoes who posted information regarding prism location above. Can you explain if the prism is missing how it would be re-installed and what holds it in? BACKGROUND: We had a DD24 installed in a new home and when we finally went to use the lower drawer it just chimes and doesn't run. Upper drawer operates fine. We've been working with Paykel on warranty repair, but they've been unable to help with no service provider available in our area. Being handy, I decided to take a look to see if I could find a loose connection or possibly see something awry. When we removed the lower drawer for said inspection a small piece of "plastic" fell to the floor. We thought this was odd but didn't think much of it until stumbling upon this thread. It turns out this plastic piece is the very prism in the picture above. Which no doubt is the source of our problem! So I'm seeking advice to understand how to reinstall/hold it in place... sort of thinking to the reason it might have been dislodged and/or if something might possibly be broken and what workarounds I might be able to implement if something is broken?

Thanks so much, dadoes! There didn't appear to be any fault code at level 3. On level 4 the 4th and 8th lights were on before I pushed the tub, nothing else happened when I pushed it. I did notice that if I changed levels and came back to 4, sometimes it was just the 4th and 8th lights on, and other times it was the 3rd, 4th, 6th, 7th and 8th. Not sure what that's about. I did have bedding and towels in in the load when it went out....things that are commonly unbalanced. I am not sure which is the '6 minute light' but if it is the 4th, it sounds like I need an OOB switch. If you have more to add, please do! If not, thanks SO much for your help!!!

I have the F&P DD24DCHTX6, it has a tall drawer on top and a regular one on the bottom. I think it's great; no splashing, no open door to block traffic or bash in your shins again. Like Bireland it took awhile to learn how to load it. Unlike Bmorepanic I've found the cleaning to be great. Some things are much cleaner than ever before. Tea strainers etc. very nice. Coffee and tea stains never on mugs anymore. Tired old wineglasses so sparkly. For the first little while I tested it daily with incrementally cruddy pots and plates and it always got them clean. Like Kimkitchy, if I could do it over again I would put a single drawer on either side of the sink. I love not having to bend over at all to load or unload the top drawer which I use most of the time. I live alone but I cook & bake all the time and there are always lots of dishes. If I could do one on either side of the sink I'd select a tall single and a regular one and put pot drawers underneath them. Others have mentioned how useful the 2nd drawer is for loading when the first one is already full or running. I do that as well but also love it for a drain-board for hand-washed items. No stupid ugly rack on the countertop. With regard to the noise I think they are very quiet and friends have commented on just how quiet. There is some sound but it's not annoying at all. Silly to admit but I wait until bedtime to put them on because then, when the house is completely quiet, you can hear them and I like the lulling swishing as I drift off to sleep.
