From newbe homeowner. I have a KitchenAid dishwasher, 8 years old.
The motor has started whining alot. It can be easily heard from across
Looks like the replacement cost for the motor is about $170 and
replacement cost for the same model dishwasher is about $550.
Which is smarter in general, fix or replace?
To say on topic, I clean some of my woodworking tools in the dishwasher ; )
Another consideration should be whether or not the mfgr switched to a
Chiwanese factory between then and now, and if that change affects (or
completely does away with) the quality and longevity of the product.
I hadn't done enough research on my washer/dryer, so when I bought the
"Made by Maytag" Magic Chef units, the washer motor blew within the
first month and the dryer bearings were innately defective, an
engineering problem which was not correctable.

I'll try to double-check. The fact that the unit still basically
operates suggested to me that the problem was probably a bad bearing. I
assumed, perhaps incorrectly, that this would mean it would be necessary
to replace the motor.
I owe it to my wallet to remove a few parts and take a closer look (If I
can't locate a diagram online). If I don't find bearings I can replace,
I'll replace the unit. For those that would be concerned, I'll turn the
power off at the breaker.
There is lots of information online. Also the pump and associated
parts frequently include a garbage disposal. Gtet a manual at your
friendly appliance parts store. Also I am sure manuals are available
Just for fun, I just took off the "lower spray arm" hoping to find a
bearing nearby (hint: it's not lefty-tighty, righty-lucy"). I just
realized the problem is not likely to be there since:
Problem sound only occurs when that arm is spinning (with water) and the
vibrations seems to be dominant in the left front (user's POV), but I
could be off by a few inches. Will do my homework...
I should have added "bottom left front" (behind the lower access port).
I watched a video that made the motor replacement look like quite the
chore. They removed the dishwasher and turned it on it's back... Maybe
it's more fun than it looks? -lol
Some food for thought
Assume one hour per use, one use per day, 365 days per year, 8 years
of service to date.
365(8) = 2920 hours of service to date.
My guess is that the design B-10 life (point at which 90% of units
have not failed) is somewhere around 5,000 hours.
(It may be a lot less)
B-10 is a statistics term often used as a design life point, IOW,
the unit has consumed approximately 60% of it trouble free
As a recent homeowner, you have yet to learn about the slippery slope
of increasing repairs you face with household appliances as they age.
Clothes washers, clothes driers, and dish washers are the worst
followed by microwaves.
Stoves and refrigerators (Ice maker excluded) tend to have a much
longer service life.
Having to pull the appliance out of a cubby hole to gain access to the
innards, all the time making sure you don't plow a groove in the floor
covering gets your juices flowing, especially at 10:00PM on a work
Then realizing that you don't have the special tool the repairman has
to get at a special screw in order to make the repair, frustrated you
ask yourself, "How the F**K do I get out of this mess?"
You have two choices, go down the road above or wisely avoid the trap.
There was a time in my life when the only things I would not try were
brain surgery and laying concrete, but I'm learning, the list is
longer these days.
Failures, on the other hand, can be VERY easy to repair; the RCA S-100
module-swap televisions had 60% good modules returned for 'rebuild'
service, meaning that RESEATING THE CONNECTOR was all
that most repairs ever required. The noise in this case possibly
the (single moving part) motor/rotor assembly at all (it'd squeak, or
leak, or hum, but unless something's out of balance, not vibrate).
It could even be water hammer (i.e. in the pipes, not related to
the dishwasher at all).
Dishwashers, and Skilsaws (note WW content!), are 'durable goods'
and well worth repair.
Reduce, reuse, recycle.
I believe in my unit that the pump and the main motor are sold as a
single module/assembly. Given the "whining" that occurs (not my
whining), I'm not sure there's much left to consider. Does the solenoid
valve do anything that could cause a lot of noise?
