DF261161S (01) Gaggenau Dishwasher - Instructions

pushed with thumb pressure and snapped rollers into place.....EASY

replacing the sensor was simple, just unplug and turn it out, but didn't solve the problem, it's a float sensor that doesn't show up on the tech sheet in the dishwasher or anywhere in troubleshooting on the internet I could find.

Went to on line video and followed it. The old gasket came right out and the new one fit right in. Started at the top middle and worked the gasket in on both sides to make sure it was evenly spaced.

I removed the old gasket easily, it pulled right out. I spent a few minutes cleaning the gunk out from the seam using a standard kitchen cleaner (it was gross and I had to do it multiple times). Tip: pay attention to the shape of the gasket and which side faces in vs. out when pulling out the old one. Also, for reference, take a photo of the old gasket and how it's positioned before pulling it out. Then, simply start at the bottom (either side) and insert the new gasket. Work your way up, over and down the other side. If it's facing the right way it'll go in very easily, if not is will be very difficult—this is how you'll know. After installation, run your dishwasher empty for a full cycle (with towel underneath the door) and check back frequently during the cycle. If there are no leaks you're done. This was the fastest, easiest way to attempt to fix a leaky door and eliminate the gasket as the problem (which it did!) If the machine still leaks the issue is likely something bigger.

There were 5 rollers still in place so I used them to show me how to snap the replacement roller in place.

I bought replacement wheels.
I put them on the post, and they snapped onto the vertical post very easily. Job done.

The repair was extremely simple. Just lined up and popped them on. No tools needed.

Followed the video on your site and it was an easy install with no more leakage.

Replaced ‘sump’ housing , seal was leaking on it- replaced inop float on water level warning system switch, and switch itself as well- replaced drain pump motor attached to sump- replaced o-ring seal at water sprayer inlet valve- replaced water inlet plastic assemble on side of dishwasher- replaced drain hose out of sump assembly.

Used YouTube video to understand repair- this is an involved repair in time and complexity- dishwasher eventually gets turned upside down once removed and stripped down, to remove the white plastic water pan , which then allows access to the guts of all the above parts- some critical seals only come with new assemblies, so you are buying that new part to get a new seal and ensure no new leaks from what you took apart.

Popped the new one right on!

easy repair, but the check valve wasn't the problem, it was the float switch that isn't on the tech sheet in the dishwasher or mentioned as a possible culprit anywhere I could find on the internet
