SEIMENS FRONT LOADER ULTRA SENSE DRAINING PROBLEM
On my SEIMENS washer, which is about the same as BOSCH, the drain problem seems to be usually a small sock jammed in the intake of the drain pump, or possibly in a hose before the pump. I found a quarter and a couple of staples in the attached settlement area where junk settles to avoid jamming the pump. Also a lot of dirt.
On the lower front under the door, while facing the washer, is a round plate with a little hole in it. Put something sturdy, a little bigger than a toothpick in there, and rotate the plate about a 16th of a turn, maybe a little more, and it comes off.
Take duct tape or similar and tape up the edges of the hole and a nearly vertical bar in the hold on the left side, because the edges will cut your hand, like they did mine.
Inside the hole you will see a black turn knob inside. Turn it left very slowly, only after you figure out where the water will go, probably a small bucket or two of it. I used a 4" funnel which got most of it, I think, funneling into the bucket. Maybe you can be more creative, but it is what was at hand. Still got water on the floor out of the garage into the street. Turn left slowly, so it doesn't dump water outside of the funnel. You will see the water is brown, silt, dirt and stuff.
If you get a lot of water out, that means the blockage is probably at the pump. If you don't get water out, the blockage is probably in the hoses from the washer, which means you need to undo hose clamps going into the pump and clear the blockage. That is harder.
Most likely it is something in the pump area itself.
After most or all of the water is gone, and it doesn't seem to unscrew any more, tug on it and it will come out exposing the pump and probably the sock.
Remove the sock, and check the pump impellors to make sure they are intact. If gone, that means a new impellor and probably a pump. Then move the impellor, it should click as it moves and stop. If it does, you have found the problem. Sock blocking the outlet.
Carefully clean out the **** inside the pump settlement area. If you leave any of the sandy gritty clumpy stuff it can ruin your pump. Also clean the plastic thingy you pulled out, and make sure the threads and sealing surfaces are clean there too.
Then screw it back in firmly, and start the washer, without clothes. I would just fill it up, starting the cycle, until it starts to agitate, then go to the drain position
With luck, it will now drain. .
This will save you a service call for something easy to fix yourself.
