Question Dishwasher motors - looking for wiring diagram

I have 2 dishwasher motors and looking for their connection diagrams. I do not know what dishwashers (make and model) they were taken from. Please help to find their wiring or connection diagram. I tried, but couldn't find... Thanks!

Motor 1:


Motor 2:

Welcome to the forums.

What is it you are trying to do with the motors ?

I can't find the first motor but a search for e22922 from the second motor, says that it's a Whirlpool Dryer motor.

They're both dishwasher motors. I know what models they are used in but I don't have any of those wiring manuals. FSP uses several different color schemes plus there will need to be a capacitor for starting.

e22922 is a UL listing number.

Trying to build a grinder. These motors should have 2 speeds, one is listed on the label at 3450 RPM, and I guess there is a slower RPM also. Need to understand how to power them.

I also measured resistance between wires (in case that helps). The results are somehow consistent if white of motor1 matches violet of motor2

Motor 1:
black - yellow = 12.8 Ohm
black - blue = 9.4 Ohm
yellow - blue = 9.4 Ohm
violet - black = 6.6 Ohm
violet - yellow = 6.7 Ohm
violet - blue = 3.3 Ohm

Motor 2:
black - yellow = 14.0 Ohm
black - blue = 10.2 Ohm
yellow - blue = 10.1 Ohm
white - black = 7.3 Ohm
white - yellow = 7.1 Ohm
white - blue = 3.4 Ohm

Two speeds but the 2nd is reverse.

These are fairly low torque motors. I don't think they would a good grinder motor.

I'm trying. I have many dishwasher schematics but none use either one of those motors. Can't guess as the motor needs to be externally started and many with a capacitor.

Interesting link Astuff but different motor.

I've successfully connected and tested these motors. These are single phase induction motors. They have 1 main and 2 startup windings (to start the motor in either direction).

At the start both main and one of the startup windings are connected to 120V, then the startup one has to be disconnected, otherwise it will overheat. The delay is up to 1 sec, I do not know the exact timing.

The main winding is one with the lowest resistance. Compare motor wire colors to the diagrams provided in the messages below to make sure you connect hot and zero wires correctly to the motor. The hot also temporary connects to the startup winding, choose one of 2 left motor wires that starts the motor in needed direction.

Once started, the hot wire has to be disconnected from the startup winding in 1 sec or less.

It is possible to use a switch to connect power to the windings but a relay is recommended due to the relatively high current through the contact and the generated sparks.

Eugene, what did you end up using for the disconnect of the startup wire after start. Also, which were the common, run and startup wire colors. It just so happens that I have the same set of motors and spent all night trying to get them to run until I found this thread. You are giving me hope. :-)

I am not sure about this... but FSP Dishwasher Motors appear to be from Whirlpool, if that is the case this Dishwasher Wiring Diagram could be helpful:

I also have the same dishwasher motor as motor 1. I am very interested to know exactly how you wired them, Eugene. Thanks in advance.
