On the "rinse only" cycle, I get a "blocked drain" message on the display about 7 minutes into the 12 minute cycle. The diswasher continues to try to pump, but eventually the blocked drain message begins to flash. When I cancel the rinse cycle to abort, the dishwasher continues to try and complete the "drain" function, but doesn't, so I have to turn off the diswasher at the breaker box. I poured a whole bottle of drain cleaner in to try see if there was a blockage, but that didn't work, and my gut feeling tells me that is not the problem, because I would be getting blocked drain elsewhere if that were the case, I believe. Any ideas, anyone?

- This solution did not address the problem of the blocked drain message. I was skeptical that it would, because the plastic screen-looking thing that Gary1121 refers to does not sit at the bottom of the tub, so therefore it can't be a drain (which has to be at the lowest point of a vessel in order to perform that function. Nevertheless, I took the screen off, which is apparently a filter of some sort, and cleaned it off, and replaced it. It did nothing to fix this problem. Again, the dishwasher, after going through the pre-rinse cycle (about five minutes), is apparently unable to drain the water and displays a "blocked drain" message. The owner's manual for the dishwasher gives these possible causes:
1. Clean the air gap [I don't have an "air gap" per se - the dishwasher drains into a common drain pipe that also serves the kitchen sink, so since this is open to the air (although there is a U-trap), it effectively serves as an air gap, I believe, so cleaning isn't an issue, and there is no indication that the common drain pipe is clogged in any way]
2. Check for a kink in the drain hose. [none]
3. Check plumbing for slow or stopped drains [no indication of this problem here or anywhere else in the plumbing].
So what could this be? Any other ideas before calling a technician? Jul 01, 2009
- You asked, "why would you think that if the drain was blocked in the dish washer that you would have problems else where in the plumbing???"
Because it's a logical inference to make: if the dishwasher drain is clogged, one possible reason is because there's a clog further down. It's one of several possible explanations.
As for the drain cleaner, I don't think it did any damage. My intention was for it to work its way through any clog in the dishwasher drain line, but it doesn't seem to have helped. My other thought here is that if there is a drain solenoid, it is not operating properly, and perhaps needs to be replaced. That could also cause the "blocked drain" message, I think. Any thoughts on that?
