When researching the F&P dishdrawers, one interesting comment that was made that really hit home for me was something along the lines of "if you are going to get dish drawers, why NOT get the ones made by the company that has been doing it the longest and has the benefit of its own research and improvements". So, I thought about that, and did some more research and learned that indeed F&P did have some issues earlier, but worked hard to improve and correct any problems. I bought the F&P dish drawers about a year ago and couldn't be happier. Just the other night they once again proved themselves to me: in the top drawer I put in a scraped of large chunks only dish that I made scalloped potatoes in and in the bottom were the baffles (greasy) from the range hood. Everything was sparkling when done.

Each drawer has a heating element. You can easily see it. Remove the rack, wash arm, drain filter, and the large stainless steel filter. The heating element is the circular ceramic disk that surrounds the pump impeller. If the heater is bad, the machine will throw a fault code and/or cycle progress will get stuck for a very long time in the main wash and/or final rinse when it's unable to reach the target temperature. You didn't say which cycle you normally use or which model is your DD (603 or 605). Depending on which model and revision is involved, Fast may be low as 115°F and Fast Eco 105°F. Household water temp has more of an effect in that case if it's already higher than the machine's target temp. If you have the standard model with LCD, I can tell you how to get a display of the internal water temperature while a cycle runs. The integrated model without LCD doesn't have the temperature diagnostic. I've gotten a milky-white residue on plastics a few times, such as on these dark blue lids. Seemed to happen when the detergent dose was a little skimpy, and for sure when the detergent I use (WM GreatValue) went phosphate-free. It *hasn't* happened any more since I've been adding STPP and using no less than 4 teaspoons detergent for the main wash.

here's mine. bottom drawer will hold my corelle plates but not my everyday china plates which are a little larger. top drawer will hold both size plates. Love my dishdrawers--so far--after a few months use. I run the top drawer twice a day and the bottom drawer every other day. I replaced a Miele that gave us lots of problems -after it was out of warranty- go figure.

I googled and couldn't find any direct answer to your question. However, I did read that each drawer has it's own motor. I would think that a competent plumber would be able to disassemble the bottom unit and re-route the plumbing so there would be no drainage possible into the bottom.
