Question about Miele Dishwashers
if you remove the door panel you will see a small hose from the fan to the combi dispener. Remove this and blow through it. Also connect it to the combi dispener and blow and then to the fan end and blow. Food and muck block the pipe and the excess water cannot escape back into the unit so instead it pours out the vent. you will find the fan is then quieter.

Welcome to FixYa.
Based on your description I'd say the issue is with the control...unfortunately.
The number"1" being displayed ( on models with the display ) is actually an error code indicating a fault in the heating process.
Bosch has had a history of this exact problem I'm about to lay out for you and this is the first thing I'd be looking for if called out to service the unit with the symptoms you've described.
As I've alluded to the issue is likely within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).
My first suggestion would be calling in an authorized bosch service tech. if that is an option for you and your budget however, If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself.
It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board.
The culprit will 99% of the times be one of the pins from the heater relay,
**Flip this over and inspect the solder joints, it will be obvious when you see it.**
This ones new, but it's where to look...
...hence the unit sit`s and takes longer & longer to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed, other-times it will eventually stop or display "1".
You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow switch indicates it has adequate water to engage the heater.
**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**
**Please disconnect the power or turn off the breaker before attempting any service to the dishwasher.**
As you alluded to though, sometimes one needs to call a tech. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau/Siemens, to service your machine.
Hope this answer`s your question, let me know if I can assist you further.

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.
If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...
