Brownouts damage appliances. It’s the smarter route to have it an intermittent use appliance engineered to turn Off than to stay on. Continual use appliances like refrigerators and air conditioners usually have timers that restrict the start up of key components like compressors following a brownout or blackout.

A Miele dishwasher has a microcomputer performing all of its operations. In a brownout condition when voltage to the computer drops below a certain point the computer will sense this and will execute a hardware reset. This is why you find the machine in the state that it is in. It is basically a feature and not a bug. Brownouts can damage the motor and other components and this is the machine's way of protecting itself. As long as it doesn't happen under normal conditions, I wouldn't worry about it. South Florida has a lot of thunderstorms and there's a ton of air conditioner usage. I'd imagine that voltage drop is rather common. I've never had my Miele DW drop out, but our voltage here is quite stable.

We have power outages frequently, and our power was shut off as a precaution for wildfires. When they turned the power back on, it was below the minimum standard required under law. Neighbors were complaining 220 appliances wouldn’t turn on. Meanwhile, I was on the phone yelling at the power company that they would most certainly get sued if my well pump broke (the 220 pump that’s in the well, very expensive to replace and is old and doesn’t have the shut off protection). They had the power fixed within the hour. Be thankful your appliance shuts off to prevent low voltage from damaging it. Also, make sure your electronics are protected from these as well.

My PC and connected equipment is on a UPS (uninterrupted power supply) in the bedroom for years (actually replaced it with a new UPS a few years ago). And latst year before the hurricane came through, I had another UPS that I connected to the Plasma TV, cable box and stuff in the living room. Even though we never lost power durring the hurricane, I could hear both UPS boxes click over to battery backup if the voltage dropped too low.

Which brings me to my point:

The original Miele Dishwasher that I had for 8 year. If it was doing a wash cycle and the power went out completely or if there was a low voltage brown out, and then the power returned to normal, the unit would come back on and start washing from where it left off with no input from me. The refrigerator, clothes washing machine, and AC will all return to their task when power is restored.

Keeping all of that in mind, two nights ago around 1am I had started the new Miele and had it set on the Pots Pans cycle, which does 2 prewashes before the main wash. I went into the living room and was watching a program. About 10 min later the living room lights dimmed down, the ceiling fan speed slowed, and the AC blower slowed, all of which lasted for maybe 2 seconds max. But the voltage didn't drop low enough for the UPS connected to the TV to kick in (as I can hear the click). A little bit later I went back into the kitchen, the clock on the stove and on the microwave was not reset (which happens after a full loss of power) but the dishwasher was still powered On, but the green Start light was flashing. I opened it up, and it's sitting there full of water during the prewash, since the tab door wasn't open. I pressed Start and only then did it resume washing.

The following day I tried a test, had it start a load, and I unplugged the power cord for 2 seconds and plugged it back in. Same thing happened, it just sits there with the Start light flashing. On my old Miele if I had done that, it would of started washing again.

So that's my real question and concern. Why would Miele go from making a dishwasher that would resume the wash cycle after a power loss (or brown out), to making ones that will just sit there indefinitely until you press Start again? Like I said before, what if I was asleep when this happened, or not at home, and hours later return to the kitchen and there is sits hours later full of water with the cycle unfinished.

I guess the only way around it would be to have a UPS plugged in under the kitchen sink and then plug the Miele into it? That way if there is any minor power disruption, the Miele won't lose power.

That’s weird. Did you check your meter to verify that you’re not getting enough power? A brown out would’ve tripped everything. In my case, we were being fed substandard power for an extended period of time. My husband told me to shut off the main and call the power company (he’s an electrician).

It's a digital meter outside, no I didn't check it, but will. In the two months that I've had this newer Model, this is now the 2rd or 3rd time that either a power outage or brown out has caused it to stop finishing a load at night.

I checked my outside voltage at the meter as it shows between 240-243v. I also took one of my uninterrupted power supply units and connected it to the power outlet under the sink, it showed the voltage as 119-120. As a test, I plugged the dishwasher into the UPS and started a wash cycle. After a few minutes I unplugged the UPS from the wall, so the dishwasher was just running off the UPS battery, and it worked fine. After that, I ended the cycle, removed the UPS and connected the dishwasher back to the wall outlet.

So I guess I'll have to find a smaller UPS that is able to fit in the cabinet under the sink that doesn't take up much room, since there is a lot of stuff already stored under the sink and can't fit a full sized 1500va unit in there.

That is strange. Your dishwasher must be hyper sensitive. We were being fedpower in the 206 range, which is below legal minimum. Well, if a UPS will solve the issue, then go for it. It’s just really strange that the dishwasher is the only appliance affected.

Have you contacted Meile to see if this is to be expected, a bug, or if there’s a setting to change the behavior?

I was going to suggest using a UPS but hesitated as it places one where it can get wet.

I haven't contacted Miele about it yet, probably next week after the holiday. I just wanted to check here first to see if anyone else with a G6000 series unit (Classic, Crystal, Dimension, Lumen, Diamond) had a similar issue with their dishwasher not resuming the wash cycle after a power outage.

I too would rather not have to install a UPS under the kitchen sink, where there are water shut-off valves and drains. Once I contact Miele, I'll see what they say, or if there's a hidden setting that can override this. I still just find it weird that the older unit would pick back up washing after a power outage, but the new one doesn't until you press Start again.

As mentioned, its likely a failsafe. Better to hit start than fry the electronics in your fancy dishwasher. To me, the problem seems to be your power fluctuation and brownouts, and not the function of your dishwasher.

I don’t think it’s a fail safe - my G6000 does the same if the power is interrupted. Miele washing machine (W1) of similar generation - it just literally carries on from where it went off.

The irony is the dishwasher has a clock display which I’ve turned on because of it convenient position in the kitchen…and the unit happily keeps time while the power is off. We had some work done at the apartment building and the power would sometimes be off hours at a time…so it clearly has an internal battery / capacitor of sorts. But as Fauguy says…all too often you come back and find if it was interrupted, it’s just sitting there waiting to start as if nothing happens, with a tub full of water from the incomplete cycle.
