I am having the same problem. Someone recommended replacing the power supply unit.
Bosch 00658328 Power Supply Unit
So I did that. No change what so ever.
The unit pumps water out fine. Never any left over. Can get it to run if I interrupt the cycle at 40 seconds or so after start up.
If anyone found a solution to fix this issue I would love to hear about it.

Also having this same issue with Kenmore Elite (Bosch build). replaced drain pump, no clogs or debris. Can use the workaround. Did anyone proceed with replacing the board or find any other solution?

Try this:
5.1 Clearing error code E24 drain obstructions
If a dishwasher doesn’t drain properly and / or shows an E24 error code, the problem is
due to drain obstructions, not a faulty power module or drain pump.
To correct the problem, (1) reset the power module, (2) correct overly high drain con- nections and / or (3) clear drain obstructions.
5.1.1 Resetting power modules
▶ Reset the power module by using Method 1 below. If unsuccessful, use Method 2.
Fig. 61: Power module
5.1.1.1 Method 1
  1. With the door closed and the dishwasher turned on, press and hold Start for 5 s. The display should show 01 or 00.
  2. Press On / off (turning the dishwasher off).
5.1.1.2 Method 2 Prerequisite:
Disconnect electric supply.
Remove toe panel and disconnect drain pump harness from drain pump. Tape the harness pump connector to make sure it isn’t touching anything. Reconnect electric supply.
  1. With the door closed, press On / off to turn the dishwasher on.
    You should hear the power module turn on and control relays click on and off.
  2. Wait about 30 s with the power on, then press On / off to turn the dishwasher off.
  3. With the power off, reconnect the drain pump harness and reinstall the toe panel.
  4. Close the door and press On / off to turn the dishwasher on.

Keep us updated on this.
Alas, E 24 has returned after the pump disconnect/reset procedure seemed to have fixed it. Is this the board? Can still use the workaround described earlier (interrupt the dishwasher 40 seconds in), but means can't use the delayed start.

I have a similar issue on my SHE4AM02UC/01 ...

Doesn't matter which program is run, Power, Regular, Quick, the dishwasher works sometimes,
it will start with the usual drain? cycle, then re-circulation?, drain? again, then goes to clean.

When I open the door during 2nd drain, it starts filling water right away and works just fine.

There's never any water left after it cleans dishes or at any other point meaning it drains just fine,
if I fill it with water and lift the safety float it drains without any issues.

The code I get when checking error codes with > and Delay, is blinking both Active and Clean,
meaning either E23, E24, or E25, as there's no error display panel on this model.

E24 isn't it I guess since it drains just fine, so no blockage ...
E25 isn't it either since it drains, so it has to spin ...

E23 possibly some intermittent drain pump issue, that fails a safety check ?

Somehow opening the door at the beginning of the wash skips whatever check it's doing
and forced it to proceed, so a blockage or bad pump would not get fixed that way ...

Could be a power module issue but others with similar problems have replaced it and it didn't seem to help.
I have already checked the easy stuff like a loose drain pump cover, and I've also had it apart and had a look
at the actual power unit module, and it seemed fine, there was one spot that seemed a bit like heat stress
that was on the other side of a what looks like a 5 pin white square relay, however if a relay was going
bad how come opening a door would fix it every single time, it just doesn't add up :)

Next I will pull the unit out and check resistance on the drain pump, they say it has to be 90 ohm.

Any other suggestions?
Thanks in advance!

Update, I believe it might be the turbidity sensor in my case ...
I need to do more testing to see if that’s correct.

Sounds good, I'll order a new sensor and go from there ...

When I left it filled with vinegar all night, it definitely made things better,
so I am thinking that was enough to clean the sensor a little bit ...
