Miele G638 CS Plus - Salt PC light flashes and will not run

Hi - if its flashing rapidly then there a unrecognized hardware issue -if on permanently - it could be the float switch inside the salt container is not working/jammed - of course theres no salt in the dishwasher container..

Cheers

Hi - its possiblily the following issues if its flashing rapidly then the electronic module maybe faulty. The other possibilties are the float switch inside the salt conatner is jammed or the reed switch for the float switch in the salt container does work.

the pump is blocked, need to remove the trays, drain plg, the gauze, scoop the water out as much as possible, thge thers a plastic hosing with a spring clip on top, remove this to unblock the pump. assemble & should be good to go.

You need to add rinse aid!

There is normally a place on the inside of the door which you unscrew and top up using any Rinse Aid fluid.

The water in the pan is what is causing the issue - need to find the cause of the leak - door seal or pin hole in a hose - possibly a leaking pump

pump maybe on it's way out, though i doubt it, is the washing machine on the same drain out? if so you may have back wash, another could be lengh of drain hose, i had the same problem with my miele dishwasher because of the position in the kitchen i doubled up the drain hose and though it pumped out fine, with the volume of water left in the hose it came back in untill i repositioned the drain hose so it could't run back, hope this helps.

Hi, 
I downloaded the manual off line and it gave me the facts I needed.  
Thank you,

The intake/drain light blinks. How do I fix this problem?

Check the drain pan area under the dishwasher, if it full of water it will trip a float switch and run the drain pump until the water evaporates or is removed by a shop vac.
