Check no water in the base either by taking front bottom panel off or tilting back. if water runs out, means you have a leak. could also be inlet valve open circuit

Hello. My dishwasher (Miele G 579 SC) does not fill water enough. When filling is done I must fill manually with a bucket to get water to a sufficient level. What might be the problem? Kind regards...


When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.

Water keeps coming into the machine, looking for electric valves.

The solenoid valve is under the machine. It will be a block of metal installed with fittings into the water pipe and it has a plastic cylinder attached to it. The cylinder will have two wire terminals on the end opposite the valve block and is typically about 3/4" dia. x 1 1/2" long.

My miele dishwasher model no G643V1 is not cleaning properly. Inlet/Outlet, Salt or Rinse aid lights not red. Contents all have gritty substance at bottom. Please help!

The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine again before using it again.

Hi My dishwasher Miele G692 SC has the inlet/drain light illuminated. I have cleared the inlet and tap connection..... Any other suggestions before I ring Miele?

Have you checked the drain? On mine a small piece of broken glass had got past all the filters and had blocked the paddles of the pump - you have to release the spring clip and take off the top of the pump housing. Miele's seem very fussy about any blockages to the water outlet system.

You then have to hold down the start button to force a restart (cost me a call out to learn that) - but it is stated, sort of, in the problem fixing manual.

Drying cycle problems

Take the door fascia off, and you'll see a pipe from the steam outlet to the Soap Dispenser in the door.
Take that off, and flush out the small bit of food that is blocking the tube.
Put the cleared pipe back in situ.
Run machine, you should get steam, and no water.
When it blocks again, and you get the water again, repeat unblocking process etc...

Miele g 646 sc (not plus)

check the inlet where it joins onto the tap as mine has a fine filter and debris from the fresh water builds up. Simply remove the pipe from the tap and **** ,this should remove /dislodge any scale etc that could be causing the inlet light to come on. Make sure you spit out the water that comes back from the machine!

Miele G841 Built in. Intake/Drain light on/flashing and the dishwasher just shuts down.

In the user manual there's a section on how to clean the non-return valve. It's the plastic piece under the wire below the triple filter. Why did you pull out the machine? Did you kink the drain hose? If you don't find a clogged valve, spin the impeller wheel several times. It's under the valve inside the bottom hole where the valve came out.
Now here's the important step- Reset the fault! Power off/on the unit. If the light blinks when you turn it on, Press and hold the start button 4 seconds with the door open. Find the combination of off/on buttons to press to reset the machine in the user manual.
(Note: If the machine runs continuously as soon as you pressed on the power button, then you have water under the unit in the safety pan. Call Miele for help.) Now select the normal wash cycle close the door and start it. The drain motor always runs first. This verifies to the brain how much water is inside the machine when it starts filling. The drain pump runs for half a minute. If you hear it running with no drain check the drain hose especially if it's connected to a disposal. Clean the disposal.. If it's not running at all the light will go on again before filling, call Miele. If the machine fill up with fresh water, the drain works. Watch and listen when the light comes on. Is it filling or did it start circulating? Open the door, are the baskets are dripping wet? Then it filled and circulated. If the light comes on several miutes later then call Miele.
