Question about Miele Washing Machines
I had to cancel a program because it got stuck in a rinse/drain loop (it seemed like anyway) when the program was supposed to be spinning. When I stopped the program - I started a rinse program to get the get a rinse. I had to stop that too - because the same thing happened. I did a drain spin program to get the water out - but the water kept on flowing in the machine. I cancelled the program - and at the door unlocked - but the water kept on flowing into the machine. The only way to get the water to stop was to turn it off from the house connection. NO fault code appeared from the intake system .

The water pressure level switch is a pressure activated switch that is used to determine the correct water level in the tub. This part is normally located behind the control panel and will have a hose or air dome tube that connects it to the tub. On washers that use an electronic control, this switch may be located at the sump area below the tub. As the water fills in the tub it will compress the air in the tube and push against a diaphragm inside the switch. The switch will control the water inlet valve and turn the valve off at the correct water level. If the tube has a leak, not enough pressure may be created to activate the switch and the washer may overfill. If the switch is defective it may also cause the machine to overfill. To determine if the switch is bad, you should first eliminate the air dome hose as a problem. Look for signs of cracks or worn areas on the hose. Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose as well. If the air dome hose appears to be ok, then the water level switch may be defective.
You can test it with a meter and with a manual test? ( first locate it in the panel, it has a plastic clear tube hose going into it, remove that tube from its connection, now put another small tube or hose into the slot where it was and have the machine set to wash cycle with water in it. Blow into the other end of the tube.
If the machine starts to wash. the pressure switch is more than likely good
( No wash- then THE DIAPHRAGM IS BAD AND SWITCH HAS TO BE REPLACED).
Another test u can make with a multi meter is by testing the prongs individually.
# 15,16,17 (don't worry to much bout the numbers IF U GET THEM WRONG) place ur meter prongs on both out side prongs or connectors of the switch.
(where the wire plugs into) take note of wether it shows OHMS or infinity ( open or close circuit) ? Now place the meter on the left outside and the middle prong, take note agin what it shows. Now place meter prong on the right outside and the middle prong. Agin take note what reading u get. ( you should actually get a reading of infinity in 1 and a reading of continuity or ohms in the other 2? Now the tricky part. Agin place a small tube or hose into the switch and blow into it, using the meter do the same test agin on all prongs. But now keep the pressure on the switch when u blow into it, in other words use ur tongue on one end of tube to not allow air to escape. When u test it agin now one of the prongs that once read infinity should now show continuity or ohms, and 1 of the other prongs that read ohms should now read infinity or open.
The other item to check would be your water inlet valve. Check it for continuity with a multi meter it should show Ohms or a closed circuit. To test it when water is overflowing unplug the unit and see if it still overflows or continues to fill. If it stops when unplugged. Then it is not a water inlet problem but an electrical signal problem going to ur water inlet valve. Possibly from the panel or board. You can also do a live volt test to see if it is getting the full 120 current, but be sure to unplug unit before testing as this is a live test.
Also another trick to check the water valve, is to first cut the water off and remove the hoses off the back of the washer. Then one at a time point the hoses inside the washer tub and turn the water back on. If you don't have good water pressure, turn the water back off and remove the strainer that should be in one end of the hose. Inspect the strainer to see if it is stopped up, clean it and reinstall it. Now repeat this test. If you have good water pressure now, reinstall hose and your problem is fixed
By the way my advice is free cuz God is good!

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

water flows though the inlet then the flow pressure should be good, if not the
inlet valve is bad or there is dirt in the filter. Also check the flow at the
inlet of the water line. Once the water comes into the system the WATER LEVEL
SENSOR - normally a pressure switch- must activate at the preset/chosen level
to give the signal to the program controller to switch on the motor. What is
most important for the motor to start functioning is that the door switch must
be ON when the door is shut or this will be an error for starting the motor for
rinse and wash.
