Question about Miele Washing Machines
I have a problem with my Miele W460 as the inlet light starts flashing after a couple of minutes of starting a cycle. The machine fills with water fine and then appears to overfill within an inch of the top of the door and three dashes appear in the timer display causing the machine to stop. The drum is full of water at this point. It looks as though it is overfilling and cant tell itself to stop. I have checked the pipes at the back and cleaned the inlet hose filter, the water pressure is Ok, water sprinkling from detergent drawer OK too. Water filling into the machine appears to be at the correct rate too. I then put the programme on to spin to drain the water out and it appears to function normally. Can anyone help please ? Thanks

Washer fills with water and overflows:
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!

We had the same problem on a Premier 500 and solved it by tilting the machine forward. Some more water ran out and the lights went off.

Check your exit hose spigot, it may be clogged. This is if your filter is all clean. There should be air for passage in the standpipe behind. Your hose should not fit airtight into the standpipe and neither too deep into it. Snaking out your standpipe would be good too.
Your filter of the water inlet valve is accessible outside the machine; it is at the water entry point. Close your faucet & check this out; this gets clogged often.
Hope i am helpful...... Click on 'thanks for trying' if not helped, your prob will be back for someone else to solve.

try to blow through the pressure switch hose back into the tub and if you have a piece of same size hose when you disconnect the tube to blow through it use you spare hose connect to the pressure switch and blow lightly do you here a light clicking when you blow into it if not pressure switch is more than likely failed when you done tested air restrictions ........RECONNECT THE TUBE TO THE PRESSURE SWITCH.....

SOURCE: water inlet/drain light flashing
It appears your timer/controller has failed in this instance.
For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...
FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.
PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.
If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.
Anything too complicated or beyond your scope should be handled by a professional.
If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.
