For a drainage fault heres what the miele service manual says for your machine
Water present in appliance and is not being drained off. The display shows
Drain fault F11. The buzzer is activated for 2 minutes.
Background information:
After each drain pump step, the circulation pump operates for 2 seconds and heater pressure switch B1/13 checks the water level. If it is too high (large quantity of residual water remaining in the cabinet), the drainage time is extended. If, after a further check, the water level is still too high, then the program is interrupted, the fault code is saved and the drain pump is activated. Fault code F11 is also registered if heater relay 1K1 is not activated after the fault code F51 register check; see Section 080-3.18. Drain hose kinked. Remedy: Check the drain hose for correct positioning. Cause: Drain blocked.
Remedy:
1. Clean the on-site drain.
2. Check the sump drain.
3. Check the filters.
4. Check the heater pressure switch and replace it if necessary.
Cause:
Ball in non-return valve in sump has not opened (e.g., jammed).
Remedy:
Clean the non-return valve in the sump or replace it if necessary. Cause: Foreign objects in the drain pump.
Remedy:
Clean the drain pump and its impeller.
Cause:
Drain pump defective.
Remedy:
1. Check the voltage supply to the drain pump.
2. If correct voltage is present, check the drain pump motor winding.
3. Replace the drain pump, if necessary.
Cause:
Foreign objects in heater pressure switch.
Remedy:
Check the heater pressure switch for blockages and correct switching point.
Cause:
Heater relay defective. Heater relay (coil or contacts) becomes defective during the drainage step (after fault code F51 register check).
Remedy:
Replace the heater relay.
there are two seperate water intake faults
sorry i have to post this in two seperate sections the problem being is that your machine is not showing the error code which is a bit odd because usually when there is an issue this is one of the first things that happens what i need to know is after you start the unit exactly how long after you start the unit does the machine not do what its supposed to and what is it doing does it start draining 2 minutes into the cycle one of the first things i do when checking a dishwasher is i first check that unit is recieveing power after this then i would check the water inlet valve to assure water is going to the machine and past the valve as well there are a ton of differnt things that you can check but I posted if you are having a drain issue i basicly need to know before i post any further what exactly the machine is doing and how long into the cycle that it starts doing this if you have any further questions message me back and I await your reply Thanks Rick
my theory on your problem i think is an intake issue which would either be under f13 or f14 on this link click this link and scroll down to f13 and f14 I am mostly going off what you wrote in your opening statement http://appliancehelponline.com/miele.htm... once again I await your reply Thanks Rick
or it could be f12 I dont think your having a drain issue its the amount of time that this happens is how you differentiate between which fault code it is that you have Thanks Rick

Hi Intake/Drain light flashing means an issue while draining. The
dishwasher is not draining properly. Please check for air gap on the dishwasher
is not clogged. It prevents dishwasher from draining properly and sometimes the
drain flow is restricted due to gunk. Cleaning or bypassing the air gap will
resolve the issue. If this doesn't resolve the issue then it is due to seized
(or stuck) drain pump. Keep handy large bowls and towels to soak the water out.
Disconnect the power to the dishwasher or turn off the breaker to the
dishwasher. Tip machine on its back; remove screws that hold the bottom tray
on. Remove the hoses to the main motor, remove electrical connections and
switch it on. If the error still appears then turn the rotary selector switch
to "Stop/End" or press the "Start/Stop" switch for approx.
5 secs to cancel the error message. Switch the appliance off and then back on
again. Hope this helps...please post back for further assistance. Daniel
The main reason for intake and drain light flashing is
clogged hose pipe. When the Dishwasher is not filling in, you'll need to check
for the water inlet valve, the filter screen and the float switch/assembly.
Also check for the float assembly inside the dishwasher. When water is filling
your dishwasher, a float rises along with it. As the float reaches a certain
threshold level, it shuts off the flow of water, thereby preventing a leak.
Sometimes the float can get stuck in the wrong position in the dishwasher and
it can prevent it from filling. Sometimes it can happen due to float valve and
on other occasions due to float switch. Inspect the water hose coming to the
dishwasher for any blockages. If these are fine then it's due to Water
Inlet Valve. Use a millimeter and check for the continuity on inlet valve. If
you don't get any value on the millimeter then you'll need to replace the water
inlet valve assembly.
Please see these videos
Hi
The float switch is in the base of the unit which is activated due to water in the base. You may have used too much detergent or the wrong detergent You need to remove the bottom panel, turn the power off and dry up the water with a towel. Run it again and check. Hope this helps... Please post back if you need more information.

Hi, I had f70 error on my miele 2430 dishwasher, having check the buttom of the dishwasher according to the instructions I managed to find out that both drain tube have been chewed by a mice in the winter. I changed both tubes and test run the dishwasher with the buttom cover open , everything was fine until I turned the dishwasher off installed the bottom cover but it seems that the float switch is not in the correct position. Sometimes when tilted on left it give f70 and if it is in the level position the intake/drain light flashes .
Please help me with setting the float switch into correct position and get it working.

Usually answered in minutes!
The dishwasher stops after initial drain, as stated in my question. I've filled the pan with water, and it drains fine. My impression is that the cycle quits because it is getting no incoming water. The water supply is fine and flowing freely. I've cleaned the intake filter. The solenoid at the end of the hose clicks, and the valve appears to be opening and closing.
Great! Where are the float valve and float switch, and how do I access them?
The Miele G2430 is not at all like the dishwasher in the video. It is because this dishwasher is different that I sought you guys' help, otherwise I'd have fixed it myself. Can you still help me, or do I need to call a Miele specialist? If so, thanks for trying.....
