1. What's the model number?
2. What are the symptoms that lead you to believe it's the pump?

@wdccruise Model number is G2472SCVi. On some wash cycles for the past couple of months up to this week, there has been a rattling noise from the base that corresponded to pumping conditions. At least once this led to a shutdown, but when the washer was rerun, it made it all the way through. Now it rattles on fill and shuts down. No code is presented in the time display. Restarting leads to consistent failure. There are Internet comments about the pump having two sections that fail by separating. I have not investigated further due to limits on my time.

@jwvideo So self-immolation is still a thing, millennia after Brunhilde set the precedent. Thanks.

In general, one expects that a device that costs significantly more than its peers brings something extra to the table, preferably something more than cachet. Behind a cabinet matching panel, the Miele is just an appliance. So what most of the price difference should have been allocated to was improved reliability. In my case any such claim is suspect, given the number of solenoid valve hoses I've had to buy in lieu of taking on another project to make a replacement. I think Miele management failed to recognize that 'fabled' German engineering is actually just like any other engineering -- it thrives or dies based on management support for quality.

I ask because there are a bunch of videos on Miele dishwashers and their pumps:

• https://www.youtube.com/watch?v=Ebgftc5CSzA
• https://www.youtube.com/watch?v=pcRTDo3wZi8
• https://www.youtube.com/watch?v=gqhq8n4GMlA

We have local Miele service from Miele employees and overall they are quite good. ...or at least have been. I hope it doesn't change as that is one reason we are willing to pay the higher price for Miele.

I feel for you though. That's not encouraging news.

Thanks, @wdccruise, I'll get to those as soon as I can. Know any American companies that make dishwashers and, like SubZero, stand behind their products?

Edited for clarity

Funny that I should ask. SubZero-Wolf makes a dishwasher branded "Cove." It is available in 24-inch and 60-cm width models. And its door panel requirements seem to be a gnat's fanny within the size of the cabinet-matching door panel on my Miele. How the panel mounts on the Cove is a mystery, but I'll look into it.

Edit/update: Door panel is mounted via posts and keyhole slots, much as the SZ compressor space panel mounts.

Update II: Cove delivery is reportedly out to August.

@wdccruise: Your video links were a good reminder of a maintenance task I have in past found to not be needed, but in this case I found in the drain pump one of the plastic "buttons" that cover the side frame to cabinet mounting screws. How it got past the "triple filter" is a mystery. Moving the pump vanes feels OK as a magnetic pump, so no broken connections between pump and its motor seem likely.

Starting the unit leads to the pump operating seemingly normally, with no rattle (thanks!) but after it has performed its initial bit there is no sound of water filling. The alarm then goes off and the panel shows an "intake/drain" warning. This has historically meant that the solenoid valve in the intake hose has failed yet again, requiring a new big-bucks assembly and dishwasher on its side repair. The present hose was changed only a few months ago.

@jwvideo: Maybe the service companies are tired of the customer abuse they have had to take on Miele's behalf.

"...after it has performed its initial bit there is no sound of water filling. The alarm then goes off and the panel shows an "intake/drain" warning."

Is the fill valve external (underneath the sink) to the dishwasher? This video shows how to replace the fill valve with a $15 valve from Amazon. Both your "dishwasher on its side repair" and a comment to the video indicate that some valves are underneath the dishwasher (boo) but apparently the repair procedure is similar.

@kaseki there is a thread here on houzz re the intake solenoid problems where several people have simply replaced with a GE solenoid valve bypassing the Miele leak detection system for a much cheaper repair that presumably is not so glitchy as the Miele system. Cove dishwashers have had an erratic performance record, some happy and others so disappointed with poor results where SubZero has bought them back. I am happy with Fisher Paykel Dish Drawers, going more than 12 years, others love Bosch especially the newer Crystal Dry models, phase changing salts to generate heat and absorb moisture for better drying.

Thank you @venmar. As it happens, I studied that thread today, got a copy of the service manual, and have a pair of so far un-ravaged, but failed, Optima solenoid-hose assemblies from my junk pile to experiment with. (I can't find the one I once took apart.) I intend to first test the experimental result that sometimes they can be cured by persuasive hammering. Second, I intend to get one of the GE or Frigidaire valves and see if i can hook it up in a configuration where I can use a needle valve to set the 4.1 liters/min flow rate that it is supposed to be restricted to. Looks like I have yet another project.

Also thanks for the Cove background info. I haven't yet tried to determine what owners' observations are. The few review sites I skimmed read like advertising.
