exquisit GSP-206

I have a dishwasher that decided to go on a strike, it turns on and all that, but doesn't wash. (no water jets)
When I opened it up I noticed some light heat/burn smell similar to plastic burning, and unable to pinpoint it exactly.
The two motors turn, the smaller top one seems to be some kinda step motor.
The large motor needs force to turn, it wont spin if I stop spinning it, it's not much force needed but some.
I checked the capacitor that connects to the large motor and it seems like it's dead.
Do I test it like normal Electrolytic capacitors or?
I noticed there were no markings of a positive or negative markings on it, is it perhaps non-polarized capacitor?

Is it enough for me to replace it or could something else have damaged also?

Re: exquisit GSP-206

You need to replace it with the correct motor start capacitor 3µf (Likely) 450vac
Look for the part number cqc07002018862 3µf, It should not be hard to find one, or check with an appliance shop.
It is a non polarized capacitor, you should be able to check it's capacity, but it is likely open. Even a capacitor check might say it is ok but the motor takes more current than a cap tester outputs.
Its a common failure and thats all that should need replacing

Yes if you have cap tester it does not need to check ESR
( however you can but with type of capacitor I do not know what value is considered good )

Now they will tell you 10% difference and then you need to replace it

I personally do not follow that rule if it is a China made capacitor

I follow this rule if it is made in China if the value is over or under 5% value I replace if it causing problems

Or if

The device is over 5 years old

Re: exquisit GSP-206

Thanks for the reply's.
Yes it's a 450v 3uf cap
So I quickly rested the cap.
Charged it with 10vDC, it took 43sec to drop down to 1v, but just 10sec or so to drop to 5v.
Checked it with an ESR meter (mesr-100)
4.04Ω

Does that say anything?
