Gaggenau GI 936-760 dishwasher

It sounds like the main circulation water pump bearings are damaged.

Sounds like there is something in the filter trap that is right before the mini disposal that is a fan blade, on top of the motor.

it could be a crinkle in the drain pipe or slight block, the pumps do make some sounds from time to time. it some time can even be the rubber grommets were the pump sits.

Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

I have a very similar dishwasher, with a very similar problem. I fixed it by removing debris from the water evacuator pump located towards the front of the bottom of the machine (the last motor before the drain hose. In my case, grape stems had clogged it up. Once emptied, it purrs once again. NOTE: don't disassemble the motor, just flush it out, there is an o-ring gasket that is a bear to re-install.

My husband ended up measuring and drawing his own template.

There is a recall on the control board of many of these models, butyour problem is likely not related. It sounds like a plugged drain system or a possible bad drain pump. That's why you are hearing the pump running constantly. I have written a guide to help. It is here. Thanks!

I had the same problem where rubber gasket that seals the motor bearings leaked water into the bearing and rusted out the bearing.

I scrapped the motor into every little pieces and extracted the bearing and just replace it. Now it is quiet as a mouse.

You need a bearing puller to get the bearing out for about $20 and the bearing is $6.
During the repair i slightly bent the shaft and i didn't straightened it properly so it wobbles a bit. But it works and if really quiet.

Mine eventually "fixed itself". I think some debris got caught and eventually (5 cycles or so) got ground up and sent through the drain. The noise changed each time it got closer "flushing out"
