SOURCE: Intake/drain light blinking on Miele G841 dishwasher

I cleaned out the drain pump and non-return valve on my Miele G658/858 and that fixed the problem. The G841 may have similar parts. It's easy to do. In order: 1. Turn off washer. 2. Remove the triple filter (the basket on the bottom of washer with the little handle. Turn the handle and remove) rinse out and set-aside. 3. Remove the standing water. I used a wet vac to remove the standing water from the bottom of the machine, but you can scoop it out also. 4. Tilt the locking clamp (tilt left) to the side. (this is a metal wire covering the white plastic valve. This valve is to the right of the triple filter basket.) 5. Pull out the non-return valve and rise will under running water. You may have to wiggle the valve a little. Pull straight up and out. 6. The drain pump is beneath the non-return valve. (it has a little plastic propeller, like a paddle wheel, inside) 7. Spin the propeller several times in both directions to make sure it's clear. ( I used the shop vac with a small hose attachment to clear the drain above the propeller compartment) 8. Carefully refit the non-return valve and secure it with the locking clamp. 9. Refit and lock the filter in place.
I haven't had a problem since and my dished are much cleaner- The problem must have been coming on for a long time.
Hope this helps,

SOURCE: Miele G646SC Plus dishwasher Drainage / inlet warning light

I had the same problem a few days ago. I followed the instructions to clean the filter and check to see that the impeller was free to rotate in both directions. The problem persisted. After reading this thread, and a similar one on another site, I tried what mikeboerma suggested in "solution #3", and bingo, problem solved. The magic combination is to push and hold the on/off button and the start/stop button.

SOURCE: Dishwasher will not go thru wash cycles

if the water is not draining at all in any of the cycle it is probably the discharged line at the bottom of the pump has become blocked. there is an access panel at the bottom of the dishwasher which will allow you access the line. take the line off of the fitting , use a set of vise grips to remove the fitting from the base of the pump.You will probably find corn or rice lodged in the diaphragm within the fitting, remove debris and reinsert the fitting and hose. Hopefully this is helpful to you.

SOURCE: dishwasher stops after 10 minutes inlet/drain light flashing

I had the same problem on a 5 year old model. It was the main pump leaking from a perished seal causing the water protection microswitch to trip. This gives the symptoms you describe exactly. Parts cost from Miele was about £60 for a new seal. Fairly easy to fit.

SOURCE: miele dishwasher red inlet light flashes

This is most probably a software glitch. I had the same issue a week ago and my dishwasher is only about 2 yrs old and only gets used on average once a fortnight.

At first I did everything as the manual shows in the troubleshooting section. The whole process takes only about 5 to 15 minutes depending on how good of a handyman you are.

When I cleaned all the parts involved (all pretty clean to start with anyway) and connect them all back, sadly the red light wouldn't go.
It looked like I was stuck with the most hated option I had left: call the dreaded technician and be prepared to depart with some hard-earned cash.

Before doing that and out of desperation, I decided to surf the net for clues, blogs, forums, etc... and on one of them I found my answer.
One blogger suggested that "if anything else fails, try the 'reset' step" which means pressing at the same time the On/Off button and the Start/Stop button. That operation put a big smile on my face (and my wife's face too) as the red light magically disappeared.

My suggestion is "first try the reset trick and if that fails try and clean the parts as the manual shows". It'll save you headaches because the reset would do the trick in 90% of cases.

I work in IT and I can understand the fact that a software malfunction would trigger the red light and not reset it.

Good luck.

Will not empty water


If the machine does not drain you usually have drain blockage. Clean the drain well at the bottom of the tub. remove and clean filter and assembly parts. Make sure that the drain hose at the back of the dishwasher is not kinked.

Several Miele dishwasher uses a pressure switch to determine the water level. A defective pressure switch may prevent the machine from starting.
If this model uses a pressure switch, the switch will be located in the drain line. When a pressure switch is defective the machine should return an error code. Here a picture of the pressure switch:


If that does not fix the problem the pump located under the bottom panel must be tested.

It sounds like there are some faulty wiring connections to the motor.

You will have to check your wiring from the timer to the motor.

Does it do the same thing if you select a different cycle on the push buttons?

The wiring diagram should be in the bottom access panel of the dishwasher or in the control panel.

Miele Dishwasher G841 - Water not draining after wash cycle

If you suspect the dish washer, try discharging the drain in a bucket. After the drain cycle check the wash tub. If water is still left, you have to clean the drain filter attached to the bottom. Refer user guide.

The final drain end of the dish washer where you discharge, the fixing junction has to be cleaned, incase it is clogged.

Draining after completion of cycle

Miele dishwashers are typical not to drain all of the water. It is the way the siphoning system is designed. You will always have a bit of standing water after cycle completion but should not be above the bottom filter. You can manually drain the dishwasher by selecting any cycle and letting it run for 30 seconds and then turn the dishwasher off. Hope this helps

Intake drain light flashing

1. Unscrew air gap which is on the counter-top next to sink.
2. Unscrew drain clamp under the sink which s connected to the air gap.
3. Use a wire hanger to push down debris clogging the drain.
4. Screw clamp and air gap back in place.
5. The dishwasher should work. Routinely clean out air gap every half year.

Inlet/ drain light keeps flashing

You have a leak and the bottom pan is full of water. You can remove the cover at the bottom front of the dishwasher and see if the bottom pan is filled with water.

Another inlet / drain light cycle interruption problem!

When the water stops too soon, it could be the "over flow" is stuck in the downward position, therefore the dishwasher thinks it's going to over flow. Check that out. Otherwise I'm afraid this sounds like the circuit board is shot.
