Question about Hobart Dishwashers
I suspect that you have something in the wash pump. It might have gone through the filter or when you cleaned the base filter, it dropped down the hole.
I suggest that you search on youtube on:
REMOVING OBJECT FROM A HOBART WASH PUMP
On removing objects from a dish washer pump, you will need to pull mains plug out gain access to wash pump. Then, use a screwdriver in back pump shaft. Turn and you will feel if there is something in pump and sometimes you can vacuum out through base filter using a wet vac.
Hope that helps.

A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.

If your dishwasher seems noisy, check these:
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.
Motor If it's the motor that's noisy, either of these may be the "culprit:"
Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.
To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.
thanks and accept the solution accordingly

Hi you probably have something in the sump drain assembly (this is a common problem with Nautilus DW's) there's a screen on the right side of
the spray arm with 2 screws remove them and take screen off use your
fingers to probe the cavity be careful it could be glass.
If it does not correct the problem
!.You may have an electric pump . and it could be pump without water . so i would say a bad pump....but since you say everything is draining well...then I doubt the later...HOWEVER...you did say it ran forever...which is absolutely typical of something in the sump...drain area...which will make the drain cycle run because it believes something to be in the drain.....there is also a check valve...that the drain hose attaches to...(it comes right off of the motor assembly) when you take the hose off there is a check valve that screws into the hose or the motor assembly...(it could have debris in the hose that is not being drained all the way out and it is finding it's way back to the check valve) ...shop-vac the drain line...or the valve is screwed into the motor assembly where the hose disconnects...and there may be something stuck in the valve...unscrew it and check that the valve is in good shape...and free of debris......reassemble...and run through cycle....if you need any of these parts...or any specific instructions on replacement of these parts...here is a great site...Quality for less and quick delivery.
I hope this helps...I believe it will....Good luck and good day....thank you for your rating my effort....The Fang.

No longer "ultra quiet" huh?
A sound during certain cycles indicates a broken part. By the information provided sounds like a pump may be the problem. You may need to contact a service tech about this issue. If the appliance still under warranty, the service should be provided for free.
Every time when you hear noises (other than the normal ones) in the appliance, it indicates there is something wrong and it will worsen over time, so as soon you hear something is not ok, get assistance.
