I've been having isses with my Miele Incognito dishwasher. Water comes into the unit but cycle won't start. Technician on the phone said to take an 8mm wrench and try to loosen the circulting

Check the very bottom tray under the machine. Remove the lower front cover, 2 screws, and you'll find a tray full of water.  A Turkey Baster will **** most of it out,  towel the rest.
Once dry, the machine will operate through all cycles, most likely.
This is a common problem with this model.  I have to do this about once a year.

I cleaned out the drain pump and non-return valve on my Miele G658/858 and that fixed the problem. The G841 may have similar parts. It's easy to do. In order: 1. Turn off washer. 2. Remove the triple filter (the basket on the bottom of washer with the little handle. Turn the handle and remove) rinse out and set-aside. 3. Remove the standing water. I used a wet vac to remove the standing water from the bottom of the machine, but you can scoop it out also. 4. Tilt the locking clamp (tilt left) to the side. (this is a metal wire covering the white plastic valve. This valve is to the right of the triple filter basket.) 5. Pull out the non-return valve and rise will under running water. You may have to wiggle the valve a little. Pull straight up and out. 6. The drain pump is beneath the non-return valve. (it has a little plastic propeller, like a paddle wheel, inside) 7. Spin the propeller several times in both directions to make sure it's clear. ( I used the shop vac with a small hose attachment to clear the drain above the propeller compartment) 8. Carefully refit the non-return valve and secure it with the locking clamp. 9. Refit and lock the filter in place.
I haven't had a problem since and my dished are much cleaner- The problem must have been coming on for a long time.
Hope this helps,
Susan

SOURCE: Miele G646 dishwasher keeps trying to pump out

Had a similar problem with an 846, but with the inlet outlet lamp flashing. the bottom tray had filled with watedr froma dodgy seal. I switched off and disconnected the electricity. Removed the bottom front cover below the door (2 screws behind the pretty kickboard which also had to come off). The bottom of the machien was a big puddle. I dried this out with paper twowel, put the machine back together and it ran fine. I am going to replace the pump seals now as the machine seems otherwise OK.

Good luck with yours. rupertvdpP

Hello RD,
Every Miele dishwasher is designed to drain water in the first 30 seconds of any cycle. Does your intake/drain light come on at all? Miele technical services can troubleshoot the fault code if you do get an intake/drain light.
The most common issue I have seen is that the dishwasher drain line is clogged.
Solution - Try checking the airgap at the top of your sink, if nothing there then check the end of the drain line usually connected to the garbage disposal if you have one. I would reccomend disconnecting the end of the drain line and putting it into a bucket. Let the dishwasher run for 30 seconds and if it drains then its a problem with your garbage disposal. If not I would contact Miele technical support to troubleshoot the fault code

Good luck

Try more or less detergent. Is rinse aid solution and detergent dispensers working properly? Otherwise, you may have an issue with quality of water.
