Common Bosch Dishwasher Problems And Solutions
I would pull the dw completely out. the bosch and siemens dw's have long drain pipes. then u can investigate if its the dw drain or the house drain. sometimes the drain assembly under the sink where the dw drainpipe is connected will clock with all kind of stuff. remove the pipe from ther and see if it's clear.
ps. if u think its frozen pour hot water in to the drain. but I think that, s not the problem otherwise your sink would not drain. does it?

This says it is 'the drain is blocked.' So most likely it is frozen from what you posted. You could heat some water and pour into the bottom of the dishwasher to try and thaw the freeze. Got nothing to lose.

I ran into the SAME problem with my Bosch SHX46A06UC /21. The problem ultimately ended up being a clog in the air gap vent, (meaning, SOMEBODY ran the dishwasher without the bottom filter being in place or not in place properly). Remove the air gap cover and upper surface nut to drop the air gap vent into the area under the sink. Disconnect the hoses from the air gap vent filter (placing a bucket under the hose from the dishwasher). Run the drain cycle on the dishwasher. The washer should drain into the bucket and let you know that your pump works and that there are no clogs or kinks in the drain hose. (This will also remove the clog if so). The air gap vent's smaller hose connection is MOST LIKELY where your clog is. Look at the upper end of the air gap vent. You'll see a couple of clips on opposite sides of each other, that hold the air vent cap in place. Using a small screwdriver, (or your hands if you can), depress the clips (or one at a time) to get to the point where you can pull the vent cap off the filter. Either use water or a thin, long blade screwdriver to force any objects out of the filter. You should now have full flow through both branches of the filter. Using water and a rag, clean the vent cap and filter. Mount the air gap vent filter back onto the sink. Reconnect the hoses and remove the dishwasher's internal filter(s) and clean them as well while you're at it, making sure to remove any debris that might remain underneath the filter and has the chance of clogging the unit again.
Run the washer again to test. You should be good!
Cheers!

Hi
E24 error indicates draining failure and dishwasher not draining issue usually occurs due
to kinked drain pipe, clogged drain filter or drain pump. First make sure that
the drain is not clogged and remove clogs if present. If no visible lint is
present then remove the lower front access panel to check the drain filter and
drain pump for any clogs, you'll need to clean the drain filter and drain pump
completely. Also, check for any food pieces stuck near the pump impeller &
clean the chopper assembly. Hope this helps...
Please post back for any further assistance.

SOURCE: OE Error
You do not have an "OE" error, it is actually a "DE" error. (Drain error) If after 5 minutes of drain time the pump motor RPM's haven't gone up the dishwasher knows that there is still water in the tub and throws the "DE" error. Often times the problem is the controller, but I have found more often that the problem is a long and/or restricted drain line. If someone had to extend the drain hose to reach a drain the extra resistance from the splice and pushing all the extra water in the long drain line prevents the dishwasher from pumping out within the time limit.
In some cases it is possible to correct this condition by first making sure the drain hose has a high loop to prevent siphoning, then running the drain line through the floor and into an open trap. (again, to prevent siphoning) Do not use extensions on the dishwasher drain hose supplied with the unit.

My mom had the same issue with her fancy bosch dishwasher! It ended up being a hose, if I remember correctly. Her problem also took two repair trips, I know for sure it was not a new motor issue. I would have someone check the hoses and the electrical panel.

Where is the airgap? I can't pull out the dishwasher. I want to verify if the drain line is frozen but can't get to it. The back of my house has an overhang and other pipes have frozen. Humor me please...if the drain pipe was frozen, how would I unfreeze it?
