Dishwasher fan fills with water

Well, I just took my hose out (pulled both ends off the connectors) and it was indeed full of junky cruddy muck, so blew it out over a waste bin until it ran clear through. Now I've put the hose back on and will see what happens next wash!

I had exactly the same problem. Just took the front panel off (bottom two screws on each side of the door), removed the hose and blew all the crud out. Problem fixed.

I am experiencing the same problem with my G851SCI dishwasher and came here to look for solutions. Did you finally remedy the problem?

You have the Miele problem, and have found the usual solution.

This happens every year or two. Take off the outside front panel to access the hose that runs from the bottom of the fan down to the dispenser, and lets the water drain out through it to the interior. Clean out that hose as well as you can. Replace. This is a stupid problem that Miele should have a permanent fix for. Grrrr.

In fact I just did this with mine today. The hose cleans out quickly, the problem is getting the front back on. 4 hands make it easier. It slips on when you start close to vertical, then slip in in and down. For putting the screws back in, you might have to use a micro screwdriver to re-align the little clips on the door panel. (You will see what I mean when you do it!) This costs a service call ($100, give or take) to call for service. It can be done at home with no added parts. I think it applies to all Miele dishwashers, and I have now done it several times. As I said before, this is a design fault and should not be necessary!

PS: I still have the puddle on the floor, so am trying again only 3 days later! But this has worked several times before.
