Whirlpool dishwasher w10632077A (Won't spray-wash) water runs in, makes a very faint noise, later will drain. I've only used it for 3 months. I've cleaned all the filters. Any ideas?

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

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.

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.

Hi,
F13 is an inlet fault.
First the unit drains and then fills with water. When the unit has intially drained open the door and manually fill the unit with water, about 5lts. This will then allow the dishwasher to go to the next step which is to circulate the water. If this works ok then the water tap is defective, water inlet valve is defective or the electronic unit is not sending the signal to activate the valve. The water inlet valve is the white square box attached to the tap. Remove this and check the filter and make sure water comes out of the tap.If ok then remove the bottom panel of the unit under the door. On the right hand side there is a 2 core cable with a male and female connector. Unplug this and check for voltage from the electronic when the unit goes to fill with water. If there is 240v then the electronic is ok. You will then need a new waterproof system from Miele.

if the bottom tub is filling with water but not washing the issues is with the wash motor, some of this model use a start capacitor that can fail, if it has a capacitor on the side of the motor it may have failed but are difficult to diagnose but are cheap to replace so worth trying, if this doesn't help or if it doesn't have a capacitor then the fault is with the wash motor.

Testimonial: "I'm going to spend this Sunday morning uninstalling completely and checking out the motor...and...if present....the capacitor. If it has a capacitor I'm going to try replacing that....if not....I'm not going to try replacing the motor... For about $100 more I can buy a bran new dishwaher. This one is only 3 years old....Very disappointed in my first whirlpool product....but a new one could be the way to go. I can install that myself no problem. Thanks so much. I'll let you know if it was the capacitor"
