Testing for No Drain error code on Washing Machine Pump Motor 

I had the same problem so I figured I would check why it’s not getting power and I found a broken wire. So I spliced it back together and it’s fixed.

Love how you overdrive the drain pump! My pump is running but ........ No code! Machine does not spin! Bought new Hull sensor, Nope! Swap Stator/Sator was not, it drives me nut!

Double thumbs up !! Test it under load!! In other words hook it up and run it. It can test good resistance through the windings and still not run.

You have to go into your diagnostics mode and reset the washer to clear any codes that are stored.

What if the pump is not receiving the 120 volts to operate from the control system? Are there locations on the Main PCB that can be tested for this voltage?

Thanks for the info, did you ever figure out what was wrong with it?

My Samsung is 14 years & has had a few problems over the years. I'm getting a no drain error. Cleaned out pump & all hoses, but it still won't pump a head higher than about 6" instead of 3'. I think the pump has seen better days.

Thanks a ton. I'm looking into why mine is having the same problems. Your video was quite helpful.

Great video, I am having the same problem and showing positive continuity so I figured my pump was good, but its not. Thanks for sharing your ideas

I just fix my washer I followed all the steps in the video and everything was good, what I find out it was a bad connection I just cut the connection and plies the wires and I put them together and fix the problem

Very clear an helpful instructions. Thankyou

The primary or main control board is probably not sending power to the drain pump because is is faulty, or the wire harness that connects from the control board to the pump is frayed, broken or there's a loose connector from all the drum knocking and swaying that occurs from a heavy wash load. The wire harness is a pain to replace and costs less than replacing the main control board. If you can get a hold of known good parts then you can swap out to do a process of elimination. If you speak with Samsung, you can find out if there's a recall on your machine, and they may replace the control board as part of recall repairs. Also, you may get an extended warranty for 1 year from the date of the recall repairs.

I wired the pump like you did and it worked fine. I have a Kenmore 110 washer. I checked the machine connection and it was 119 V on the multimeter either when the washer was manually set to pump or cancelled in standby. When ever plugged in the pump connection had power. The rigged power wire had 120V, the machine 119 all the time and pump did not go. What gives? Thanks.

Having same issue with washing machine. ( Kenmore 110.21302010 ) I pulled the pump out, did the same test. Put it back in, and it came on, then stopped. I wiggles the wires and it started working. I narrowed it down to a specific spot. Cut it, but it looked fine. Put it back together and it wont come on at all. The motor says 120V on the side. Looks like it is getting 30VAC. It's about 10 years old. Could be the relay on the control board as well. Carbon I'm sure has built up some switch 120V for 10 years. Will be cutting the relay apart to check it next.

Good one mate , you’re a legend

Bro thank you so much

What was the final trouble shoot. My suggestion would be to take a voltage probe reading (backprobe) on the switch plug at 2:32 start tracing back

HOW/WHERE do we get a power cord to connect to the pump? It’s not like we’re all electricians and can make what you made. No appliance repair shop will help me.

And that black rubber grommet gets stuck too. Make sure that is not stuck closed

Thanks for giving me something else to check on my pump....this thing is driving me crazy...

I have the same issue with my Samsung Flex Washer Model WV60M9900AV. The tech tested the voltage of the drain pump and it was a correct voltage and said the board was not sending the correct voltage. I replace the board via ebay (since it’s no longer manufactured by Samsung) but it still not draining. When I turn on it makes a sound and there’s a delay and stays in the 11 minutes. When I run the diagnostics it stops at 7 (draining cycle) and shows the SC code. Do you think I should replace the pump and cut the connection and plies the wires together?

Thanks for sharing that's the issue I am having right now the pump only works intermittently. For example ND error code will pop up and when I press the start button it will erase the code and the pump will work again and that continues to be repeated over and over again with almost every load. Did you find out the issue? I was thinking maybe the board?

Just for those reading this who are inexperienced... unless you know well basics of electrical safety DO NOT make your own extension cord adapter with a 120VAC outlet, even with the switch you could easily injure or kill yourself or start a fire. At the very least DO NOT connect or disconnect the cord from the pump while the cord is plugged into the wall, even with the switch off.

Was the main circuit board the problem?

On my pump, N and L are not marked. How can I tell which way to connect it?

Thanks

How do you know which is hot wire?

Very helpful! Thankyou!

First replace it, test it. I like it.

If you contact Samsung- they will automatically reset the mother board in the washer thru the phone! That’s your issue!

Does polarity matter? How do you know which is the hot and neutral?

Is there a name for that type of external power cable you used? This is a great video. I’d like to test my pump before I spend $100 on a new one. I’d prefer the plug with the switch on it too, so that it doesn’t turn on as soon as I plug it in.

Do the positive or negative terminals matter when performing this test on the drain pump?

great! my one i found the drain motor faulty by tak tak tak sound :-)

yout water level hose might be pluged... try to blow it

how did you do the two pieces? you bought them? what are they called? haha i tried to test it but just by holding the two wires i cut...

Why my Samsung washing machine has two drain pumps

When you connected the load test does pos/neg matter?

Main board?

What is the name of the manual switch you used? My husband would like to get one.

Did you make or buy those wires to test the motor?

Thanks.

tnx l lot big like

Control panel?

Thank you!

Did you ever figure out

You didnt mention whether u used that made up lead direct to mains which would bec240v or an adjustable voltage supply ? Thanks

The hose

Relay

Ever figure out what it was? Working on my pump now

My meter read 11 ohms. I assume the pump is bad?

Definetley the computer maybe a relay broke...
