We have a F&P DD603SS that is leaving behind about an inch of water in the tub after each cycle. This happens on both the top and bottom drawers. I looked through the past forum posts about the DDs (why doesn't anyone describe their issue in the topic title?!?), and found that the problem is likely caused by a clogged drain line.
I removed the drain line from the upper drawer. The non-return valve fell out (more on this in a moment) and about two cups of water soaked my shirt. I wasn't sure how to test if the drain line was clogged. First I blew through it, which didn't work -- no air flow. Then I filled it with water from the faucet. It spilled over the top and then very slowly drained down through the hose. I'm assuming this confirms my diagnosis of a clogged hose.
I looked on Sears PartsDirect and found that the manual's specified part numbers (525966 for upper hose and 525967 for lower) have both been superseded by 527137. That's fine but each hose costs $40; is there an acceptable way to clean out a clogged hose rather than replacing it?
Now, about that non-return valve. When it fell out I didn't see where it came from, or which direction it was installed in the hose fitting. The manual has no parts diagram (?) and the Sears PD diagrams show what I think is the NRV but the part number has no corresponding product page and anyway the drawing is too small to see how the NRV is installed. Any guidance here would be appreciated as well.
PS I do realize I misspelled "Fisher" in the post topic but I am not able to change it. Sorry, F&P marketing department!
