My dishwasher did not drain after washing it's second load yesterday. I just had my garbage disposal replaced the other day and ran probably 3 loads of dishes since. The drain line to the disposal is clear and empty however there is water pooled in the dishwasher which I bailed out. I would have expected to see some water in the drain line which is a clear plastic line which seems dry except for a little debris within which is too small to be a problem. I took out the sprayer, the large circular strainer at the bottom and there is still water pooled inside. My guess is that perhaps the drain from the D/W is clogged with debris but do not know how to clean it our and am afraid to just start taking things apart. The garbage disposer is working very well and I think its recent replacement is coincidental.
