Thank you everyone who has posted here. All your posts were helpful. We have a Miele G2472SCViSF Optima dishwasher and have our second intake valve problem in 2 years. As mentioned above each fix is $400+. We were deciding whether to fix again or buy new. It is frustrating to have to buy a new $1500 machine when this one is only 6 years old. The advice above "don't keep replacing the same part" makes sense. The service tech says he has a lot of customers with this problem on this model and he himself suggested new made more sense than repeating the fix. Very frustrating and disappointing that Miele doesn't "own" this issue. Also, we are in Issaquah WA (with a water hardness of 1.6 gr/gal which is really low) so hard water isn't causing the intake issue.
