Disconnect the power to the unit. Remove the lower access panels and check the tray under the dishwasher. You will probably find it is full of water. Use a towel or a sponge to remove the water. There is a float that will stop the operation of the unit and run the pump if water is in this tray. Test the unit. If there are no leaks, check the drain hose under the sink. THE DRAIN HOSE MUST RUN UP TO ABOVE THE TOP OF THE MACHINE THEN TO THE DRAIN. If the hose is not set up like this, water from the sink drain will flow into the dishwasher and overflow into the tray under it.
If there is no water in the pan under the dishwasher there may be a problem with the pressure switch at the side of the pump housing but the only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance.

SOURCE: My Bosch SHV46C dishwasher keeps running, even
I have a Bosch that was stuck in pump down mode even when the door was open.
The problem ended up being too much water in the drip pan below the unit. There is a float in the drip pan that actuates the same limit switch as the internal overfilled float.
I had recently cleaned the incoming water filter and must have loosened the water line tube.

Following is a complete trouble shoot for your dishwasher.
Most probably a float valve or alignment of the door interlock switch.
Start with the simple things and work your way from there. You will be
amazed how many people call a plumber who flips a breaker or simply
clears a stuck float valve (for $80 minimal fee).
If no lights are coming on.
First check the breaker to the machine.
If
you have an exposed power source to the machine such as a plug or
junction box open the box and check the wiring is intact and not rusted
etc. Take care here and shut the breaker off first.
No go so far?
Check if your float valve is jammed.
The
valve is a safety feature to stop the machine from over filling. If
anything gets under the valve it will jam open and stop the machine.
Look
inside the machine on the floor will be a small float valve. Looks like
a small upside down cup. Lift it and clear anything from underneath.
Not the float valve either?
Check the door interlock latch.
Much
like a washing machine a dishwasher will only operate with the door
closed (or when it thinks it is closed!). There is a metal tab that
engages a switch in the door. This is the same switch that activates as
you operate the handle to open the door. If it is misaligned it will
not signal the machine that the door is closed and the machine will not
operate.
You can check this by overriding the locking tab. Put
a screwdriver in the door latch and press the switch. You should see
the lights come on and power flow to the machine.
Note: if the machine is in run mode you will get water spraying.
To
fix this problem bend the tab to properly engage the switch. Or if
necessary loosen the screws retaining the switch and move it to
correctly align with the tab.
Not it?
OK now you are into electronics.
First
is quite simple. Some units have an internal fuse to protect the
control panel. Check that first. Take your time and take care. Turn the
breaker off.
The control panel is screwed in place. Remove the
screws and gently remove the control panel. Take care not to have parts
of the door latch fall out or springs drop out etc. On newer units it
is very simple as it is just a circuit board. Look for the fuse and check that it is OK. Replace if necessary with correctly rated thermal fuse.
=======================================================
Do you have water in the bottom of the machine?
Power is there, lights are one, seems to want to work. Water will come in but will not drain.
A
small amount around the drain is normal for some machines. This is held
to keep the pump primed in some units. However it should not fill the
bottom of the unit. You know what it normally looked like so it if is
full then you probably have a jammed float valve as above or a clog in
the drain.
Drain clog.
Remove the cover from the drain in
the bottom of the dishwasher. They usually lift out or have a few
screws holding them down. Simple to figure out just take your time and
try not to force anything. Look for a clog and clear if necessary.
Your
drain can run either direct to the drain under the sink or to the
disposal unit if you have one. The drain can clog at either point.
Check
by disconnecting the drain line from the dishwasher where if connects
to the sink or disposal unit. Look for a clog and clear if necessary.
Water
exits the machine via the drain pump. If it is not operating the
machine will not drain. It will fill usually to the point where the
float valve lifts and does its job by stopping the machine before if
floods your house.
If you have water in the machine to the point the float valve is lifted then drain it out first.
Your
machine should be running now. Lights will come on and it will run
again to the point where if fills with water and trips the float valve
again. If so then check the pump and timer (see also timer below).
Remove the units as per below.
If your pump is belt driven check he belt (very few have belts).
If
direct drive switch the unit on and let if run to the drain cycle. If
the pump does not come on check for voltage at the pump during the
drain cycle. If you have voltage replace the pump. If not it is the
timer that is faulty (see below).
---------------------------------------------------------------------------------------------------
OK now your are getting to some deeper issues. Not necessarily hard but only go here if the simple things are OK.
If
you are not getting water into the unit but you have lights on and you
hear clicking and the timer runs and things are trying to work then we
know you have power and the timer is running.
No water coming to the unit.
Make sure nobody shut the supply line off. There should be a tap under the sink on the water supply line to the unit.
Turn the unit on an listen at the base for a click as the water supply solenoid (electric switch) opens. No click?
Check
the solenoid. Remove the machine from under the counter. There will be
screws holding it to the underside of the counter. You may have to
lower the legs to get it out. They turn with a wrench to lower.
Under
the unit where the water supply line comes in is a solenoid switch it
opens to allow the water to enter the machine. Water comes in under
household pressure (it is not pumped in by the unit). Chances are it is
faulty. Replace it as it can't be serviced.
Still no luck?
The
unit is guided by a timer. The timer tells the machine what to do and
for how long. If it fails the unit will stop or jam in one cycle. If
you have a physical switch the you turn to select the type of wash
cycle check it. If you are all touch control then replace the whole
board or machine.
To check the switch open the control panel
above and use a voltage tester to see if you have current at each cycle
point. Cleaning sometimes helps if not replace.
Hope this helps you. Please rate this tip for me.

Hi Martin.
There is no Error H24 on Bosch machines. What the display is trying to tell is H2O, incorrect displaying may be caused by defective LCD display or board.
H2o is displayed when there is an inlet problem, either because water pressure is too high, too low, inlet hose is kinked or blocked, inlet valve is devective, or pressure switch is defective.
If you get problem only when selecting Intensive, which requires higher water pressure, then the problem can be pressure from the house lines, inlet valve blocked or pressure switch.
Let me know if this helped, in case do not forget to accept.
Regards.
Ginko.
