Fixing Old Dishwasher Motor - Starting Capacitors Needed?

AI Thread Summary
An old dishwasher motor requires a manual twist to start, suggesting it may need a starting capacitor for proper function. However, many users note that dishwashers typically do not use capacitors due to their small size and design. It's recommended to check if the motor has starting windings that disengage once running, which could explain its roadside abandonment. Suggestions include contacting the manufacturer for guidance, searching for the specific part number, or seeking schematics from Wilmar. Lubrication might also help improve the motor's performance.

I found an old dishwasher on the side of the road one night, and naturally i jumped out and scrapped it for parts.

The big motor that sits on the bottom works
My question is for the motor to turn i have to give it a twist to get going and then it turns fine.

I think I need to put on some sort of starting capacitors to give it a kick right?

thanks

Some motors have starting windings that get switch out of the circuit once running. Not sure if yours works that way. If so, that might be the reason it was on the side of the road.
 
From all the dishwashers I've repaired, in all that time I can't remember one ever having a capacitor. The things are so small, I don't think they're needed.

You could

1) try and contact the place that made the dishwasher and see what they say,

2) do a search on the part number and make,

3) contact Wilmar (1.800.345.3000) to see if they can find schematics and replacement parts

4) post photos of your motor here to see if someone recognizes it...

:)
 
May be some lubrication can work...

You sound like you should be on that junkyard wars show lol.
 
You need a starting capacitor.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
