UNFORTUNATELY, THE TEMPERATURE IN MY COFFEE MACHINE DOES NOT RISE ENOUGH AND WATER DROPS

Maybe the filer is clogged and needs to be cleaned out or replaced. Or The temperature of the water used during extraction is a big factor here in influencing how bitter or over-cooked or how weak the coffee will taste. Weak coffee can be a result of using water that is too cold . The ideal coffee brewing water temperature is around 195-205 degrees or about ~30 seconds off of the boil

thermotatic switch is defect, kan be replaced. Open bottom and look for the switch.

Could be stale yeast or poor bread flour.

Set the temperature to "extra hot" If still not hot enough, try zapping your coffee for a few moments in the microwave.. no coffee machine will boil the coffee as this would burn and cause an awful burned coffee taste

Here is what I would do;
1. Determine if you have noticed a change. i.e was the coffee hotter in the past or has it always been this temperature. If the cups are cold or the amount of water used for each cup is small then the resulting coffee will be cooler than if warm cups were used or if the amount of water used was larger. Also if the water is not hot enough you will not get a good Crema and coffee taste will not be correct.
2. Assuming the problem is not '1' above then the likely causes is the flow through water heater. This heater is used to heat water for coffee and also for the hot water. So if the hot water pipe is also not producing hot water then you know it's a problem with the flow through water heater or power control of this module. In addition to the actual heater there is a temperature limiter, temperature fuse and a temperature sensor. If some heating occurs then it is not the temperature fuse. But it could be a fault in the actual heater, the sensor or the limiter. These components are at mains voltage and thus identification of the fault and replacement of defective parts should ONLY be performed by a trained Miele technician. So if this is the problem its best to call Miele.
I hope this helps. Regards

Evening to you
Not hot enough, do you leave it to stand with the green lights on?
By my experience the machine is best left on so everything is hot when the water passes through.
To let some time pass before you make the next cup.
And lasly to make sure that machine is clean.
Good luck

Check the thermostats on the machine, they may have installed 250°C thermostats on the machine. Also check the manual for the machine it will tell you what thermostats or the high temp on the machine.

Usually this is the expansion of steam as the heating element quickly rises to the preset temperature. This process heats the water to the correct temperature and causes the water to flow upward from the water reservoir. Then out the brewing spout over the coffee grounds.

It will usually make strange noises at the end of this cycle too.
The water is used up and remaining steam is vented.
Sounds more like a burping and last minute gurgle really. :)

Hope this helps!

This sounds like a common problem with tankless type water heaters. The modulating burner has a set Btu range it can operate within, a maximum and minimum. With very low flow rates and very low temperature rises, the burner has trouble maintaining a steady output temperature because the btu load drops below the heater's minimum input. Typically the machine will overheat the water beyond it's setpoint, the burner will cut out, and then re-ignite once the output temperature has dropped low enough.
The solution to stopping this behavior is to simply increase the water flow through the device (i.e. higher flowing fixture or larger pump). This type of problem is exaserbated with recirculation systems that bring a very high water temperature to the unit.
Higher end tankless brands have a lower minimum input btu and thus fewer problems with this.

you must have a filter and coffee in the basket for a full drain.the weight of the water is enough to open the basket when its full but as your trail run ended the final amount of water is not enough to open drain drop. with filter and coffee in it there is enough weight to keep drain drop open so all water can drain!
