New Miele DW does not regenerate

[mrboilwash]

After 22 years my old Bosch decided to no longer heat the water and to be honest I was glad it did so I could finally justify a new dishwasher. (That`s the downside if you can do minor repairs yourself)
Got a BOL Miele and while it seems to be a tad louder than the Bosch I like really like it and don`t regret my decision at all.
The manual mentions a regenerating cycle after every ninth cycle if water hardness is set on factory setting.
I did not notice anything unusual at the beginning of a cycle and I think I think I`ve done more than 9 cycles so far.
One time I went into the service menu to program a second interim rinse so this might have thrown the counter back to zero again.
Then I decided to up the water hardness to the max setting which made me to believe there should be a regenerating cycle before each wash cycle, so far two cycles are completed but still no regeneration.
Should I worry and contact Miele or just wait and see for a longer time?
How exactly does regenerating perform?
It just does a very short drain and a longer one then fills and starts to wash.

When salt regeneration is needed, it will do it before the cycle begins as soon as you hit start. You can tell if it’s going to regenerate as it will start to fill when you hit start rather than drain. It will do a series of fills and drains over a couple minutes or so before the cycle begins.

Ours is set to soft/medium hardness (12°dH) and regenerates every few cycles though I haven’t counted the frequency it maybe regenerates the softener for our usage twice a month.

Thanks for the reply! It never did a series of fills and drains in the six weeks I`ve had it, so I think it`s time to make a call.

Might be worth keeping an eye on it and see how you go. I must say ours is very economical with its salt usage even compared to my previous Miele dishwasher, and much more so than the Siemens IQ700 that we had for a couple of years before the current one. I’ve not yet finished the 1kg box of salt which I bought when the new Miele was delivered in July last year. I also find it needs a lot less rinse aid.

How are you otherwise finding the results? I still can’t believe how well ours cleans with very little water and electricity even compared to the previous, and back then very efficient, G6000 series machine that I had before.

Another thing you could do is start the machine and then test the hardness of the water that it has filled with. If there's any hardness present, it's not working.

When I had a modern Miele dishwasher recently, I could tell when it was going to regenerate on the next cycle because it would fill the brine tank at the end of the preceding cycle. Normally the cycle would end with a drain. But if it was going to regenerate at the start of the next cycle, you could hear it filling for a few seconds before the cycle ended.

Of course it's still early days and I wouldn't worry too much about it just yet until you've done more cycles.
