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.

SOURCE: Inlet/drain light flashes on miele dishwasher and

The outlet pump is triggered by the anti flood micro switch via the polystyreene float on the base of the washer. If any water for whatever reason (leaky pipe)is on the floor the machiene automatically switches to pump out mode and only works once the water and the cause is rectified

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: Have Miele G653 SCVi plus. We have inlet/drain flashing red light

Hi,

Sounds like something is caught in th drain pump as the unit has to drain first before anything else happens. Remove the filter and the non return valve which is under the clip in the sump of the unit. In the manual it shows you this. Make sure the drain pump is free of any foreign particles like broken glass. Then start the unit again so it goes to drain without the non return valve in place. This will then throw out any foreign particles as well.

or it could be the drain pump is activated all the time which is the noise you hear as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. You will see the float at the front. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck

Clean out the pump trap. If you are on well water or just have very hard water, your inlet valve may be becoming constricted as well, remove the fill hoses from the back of the machine and shine a bright light into the valve to see if the screens are getting clogged with debris: In this case, follow the instructions the computer is giving you.

Cva 4070 drip tray issue


Miele CVA 4066 -Empty drip tray warning would not go off even after draining the drip tray, cleaning contacts, and resetting power. Water was coming out from under the empty tray.
I pulled unit out and removed sheet metal in rear around water inlet. when I attached water line and power cord & turned on power, I could see water dripping out of one of the 2 solonoids on the water inlet valve. $168.00 from Miele and no expensive service call.

we have the same dishwasher with the exact same problem. I just pulled it about one or two feet out of its little cupboard thing and the error goes away and it works again, i think that it must extend the hose and free it up a little bit.
