Re: Loud noise when unit is pumping
Sounds like it is not getting enough water. Try adding water to it to see if the sound goes away. Start the unit at the begining of a cycle, open the door after it has started to circulate and see where the water is at. If it is low then you have a problem with the amount of water coming in, possibly the waterproof (valve) is going. If the level is good and it happens later in the cycle, it could be a drain issue. You may have to get in a tech.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Is the Intake/Drain light in the front dislay is flashing? if so, the drain hose might be clogged most probably. Most of the times accumulation occurs where the drain hose connects to the drain pipe under the kitchen sink. This can be easly cleaned by disconnecting the hose and removing any food waste from the pipe and hose. The other cause could be the check valve near the drain pump contaminated. The check valve is located near the bottom filter. This check valve is secured with a wire bracket and can be easly removed upon slidding the wire bracket. Rinse the valve and make sure the ball inside moves freely. Also verify and clean the ports where the check valve connects.
The Intake light is also the Drain error light. If the light is flashing, then turn off the dishwasher and clean the triple filter, the drain pump and the non return valve and make sure that there are no kinks in the drain hose.
Make sure the water is ccoming in at a pressure above 4.5 psi. Also make sure that the water valve is open and clean the water intake filter.
The final possibility is that the Waterproof system has tripped and you need a Miele technician to service the unit.
Loud buzzing sound is coming from drain pump. It is due to a clogged drain pump or a drain filter or a kinked drain hose. To resolve the issue you'll need to clean the drain hose, inspect if the drain hose is plugged. If the hose is fine, then remove the front kick panel and access the drain pump and filter, if you are unable to find the pump and filter remove the back panel as well and trace the drain hose to the bottom of the tub. There is a drain filter connected with the drain pump. It usually gets clogged, and needs to be cleaned every 6-8 months or so. The drain filter is a small white filter connected to drain pump with a hose. If it still doesn't work then you'll need to check the connections of the drain pump, check the electrical connections with a multimeter.
Hope this helps... Please post back if you need more information.
you could have sludge in the crankcase that is blocking the intake screen for the oil pump ... that happens a lot if oil isnt changed regularly .. in some cars it happens even if you do. ...the clatter you hear is the valve lifters collapsing . they need oil pressure to keep them extended properly ... if your oil pump isnt bad it soon will be .. it needs lub also or it will quickly be damaged ...sometimes you can wash out the sludge with kero/oil mix but the safe thing to do is drop the pan .. clean up the sludge and replace the oil pump.while you are there ...once you have the pump working you can first run cheap oil to clean out things ..then drain and install synthetic ...that will do a better job of cleaning out remaining sludge ... of course make sure you have the proper amount of oil to start with .. make sure there is no water in the oil (milky oil) .. make sure oil filter is not clogged ...some oil filters have a one way valve ... that can stick if the car isnt run for a long time .. ....
I had the same issue of filling up after a couple
hours but mine started making some pretty loud noises as well just
before shutting itself down and lighting all three lights. The top
drain valve would no longer work and the only way I could drain it was
through the bottom (gravity) drain valve. I took the unit apart and
found that the simple water pump that is used for draining and the
evaporating process had lost the thin filter screen on the bottom and
the screen became lodged in the impeller of the pump preventing it from
spinning. I removed the worn and broken plastic screen, carefully
pushed the impeller back up on the shaft until it bottomed out, and
cleaned all the built up sediment off the entire pump. After
reassembling everything, the ac unit runs like new again and the noise
is completely gone. Cost? $0 I imagine you can just order a new pump from sharp and save the time and effort of cleaning the pump. Hope this helps!

your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.
there are two components that start before the circulation pump.(wash noise you hear)
first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.
the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..
if your hearing clackling try and clean the pump and the hose leading into the pump for a coin ,,small ,,(dime),,,hair clip,,also its a must that you use he detergent,,or you sude up,,if you do use he your using to much,,now bleach the unit out on a normal cycle hot wash cold rinse with about a pint of bleach...and no you can purchase part of a pump..it comes as you see it in unit..onthejob
something in the impeller housing. not usually serviceable. not sure if that unit has two pumps. you could look underneath the tub and try to determine that, and where the noise is coming from. i am confident the issue relates to a pump unit. good luck mark
