Still getting Nd code after replacing pump

Customer Question

Still getting Nd code after replacing pump
Submitted: 1 year ago.
Category: Appliance
Expert:  MRANSWER replied 1 year ago.

Was the pump bad?

Customer: replied 1 year ago.
How would I know it was bad?
Customer: replied 1 year ago.
Most everything I read said to replace the pump if getting code nd
Customer: replied 1 year ago.
Why no response
Expert:  MRANSWER replied 1 year ago.

I am not here 24/7 waiting for replies- you replied 30 minutes after my inquiry. Replacing a part with no diagnosis is pointless. Does the pump even run?

Customer: replied 1 year ago.
Expert:  MRANSWER replied 1 year ago.

How is the discharge flow then?

Customer: replied 1 year ago.
I ran the quick service cycle and got passed code - no error codes
Expert:  MRANSWER replied 1 year ago.

That is not what I asked.

Customer: replied 1 year ago.
Please opt out. I would like to work with someone else. Thank you.
Expert:  Appliance Guru replied 1 year ago.

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue to get is diagnosed correctly.

I am a different tech, when does the ND code come up?

Expert:  Appliance Guru replied 1 year ago.

Ok can you check the door latch, that may be bad and then the unit will think the door is open and will not START. That sounds like the issue. Can you check the latch switch?

Customer: replied 1 year ago.
Before the spin cycle
Expert:  Appliance Guru replied 1 year ago.

Ok can you hear the pump running at all if you set it to a DRAIN/SPIN cycle?

Customer: replied 1 year ago.
There is only a spin cycle.
Expert:  Appliance Guru replied 1 year ago.

Yes if you set it to that does the pump run?

Customer: replied 1 year ago.
I will try that.
Expert:  Appliance Guru replied 1 year ago.

OK I will be here just get back to me thanks! and sorry about the other tech I need not say more:)

Customer: replied 1 year ago.
The pump came on before it has started to spin. Is that normal? When should the pump come on?
Expert:  Appliance Guru replied 1 year ago.

Yes the pump should basically run the whole time correct. Is all the water pumped out?

Customer: replied 1 year ago.
It sounds like there is still a small amount of water left. It is spinning know but I don't hear the pump running.
Expert:  Appliance Guru replied 1 year ago.

Ok does it spin to speed with no code?

Customer: replied 1 year ago.
It makes a noise from the back when it is spinning-like something is in the drum.
Customer: replied 1 year ago.
I have 4 minutes left to finish spin. Pump went on again.
Expert:  Appliance Guru replied 1 year ago.

OK I know what the issue is on your unit for that code...can you get at the p;ump again with the front off?

Customer: replied 1 year ago.
That noise stopped after the pump came on.
Expert:  Appliance Guru replied 1 year ago.

OK can you get to the pump again?

Customer: replied 1 year ago.
I have front load do you mean drain pump or pump in front of machine? Finished spin cycle no Nd code.
Expert:  Appliance Guru replied 1 year ago.

OK and you replaced the drain pump correct?

Customer: replied 1 year ago.
You need to give me about 30 minute to get the front off
Customer: replied 1 year ago.
I replaced the drain pump.
Expert:  Appliance Guru replied 1 year ago.

OK here is the issue, this is an odd issue only to that unit. Did you remember seeing the large Black boot tube kinda laying in the middle of the machine to the pump?

Customer: replied 1 year ago.
Do you have instructions on how to remove front cover?
Customer: replied 1 year ago.
Expert:  Appliance Guru replied 1 year ago.

Ok just get back at the pump...you will see that large sump boot going to the pump inlet...It basically lays on the base frame right?

Customer: replied 1 year ago.
Very familiar with what you are talking about.
Customer: replied 1 year ago.
Do I remove it?
Customer: replied 1 year ago.
Don't keep me in suspense what do you think the problem is?
Expert:  Appliance Guru replied 1 year ago.

OK no get a piece of foam about 3/4" thick and place it under it so the boot is held off the frame and you will have no more ND code...The issue is the boot is collapsing on itself cutting the pump off from water. I have ran into this a couple times on that unit.That will fix it!

Customer: replied 1 year ago.
That did not work.
Customer: replied 1 year ago.
Can you contact me agian
Expert:  Appliance Guru replied 1 year ago.

WHen it shows ND is it full of water?

Customer: replied 1 year ago.
a lot of water.
Expert:  Appliance Guru replied 1 year ago.

Is the pump running when this happens?

Customer: replied 1 year ago.
No.
Expert:  Appliance Guru replied 1 year ago.

OK after that if you set it to SPIN does it drain fine?

Customer: replied 1 year ago.
It did before. It pumped the water then spun then pumped the water again.
Expert:  Appliance Guru replied 1 year ago.

Ok so right now if it is full of water and the ND code is one and you reset it and set it to SPIN does all the water pump out rapidly?

Customer: replied 1 year ago.
I will try that. After I got the nd code I turned the machine off and turned it back on and have set the spin cycle. The pump cam on and most of the water drained out but not all just a little bit left.
Customer: replied 1 year ago.
I can see about 2 cups at the bottom back side of the drum.
Customer: replied 1 year ago.
It has not started to spin yet.
Expert:  Appliance Guru replied 1 year ago.

Ok I would double check that sump boot make sure it is not collapsing on itself and make sure the sump boot is completely clear, its sounds like it is either partially clogged or that sump boot hose is the issue. I do not think it is anything else.

Customer: replied 1 year ago.
I checked that boot and I don't see that it is blocked in any way.
Expert:  Appliance Guru replied 1 year ago.

It typically is not blocked, but where it sits horizontally that section squats down in the middle when the pump comes on since it is sucking...that makes the boot collapse and starve the pump and then it cavitates and nothing gets pumped out.

Customer: replied 1 year ago.
I don't think it is the boot - being clogged. It was never touching the bottom of the machine.
Customer: replied 1 year ago.
What do I do
Expert:  Appliance Guru replied 1 year ago.

IF the pump is running and it pumps out all the water in SPIN fine every time, then the only left is a control issue from the main control board. If the control is bad it may not be signalling the pump to activate during the RINSE section that is about all that it could be.

Customer: replied 1 year ago.
How can I tell if it is doing that
Customer: replied 1 year ago.
Which means I should get a new machine due to the cost of the control board.
Customer: replied 1 year ago.
What about the pressure sensor.
Expert:  Appliance Guru replied 1 year ago.

The sensor will not cause the issue of the water not exiting the machine, so either this is a problem with the board or that sump boot, but I have done a ton of these and that boot always is that issue.

Customer: replied 1 year ago.
Should l replace the boot?
Customer: replied 1 year ago.
Does the boot go bad over time?
Expert:  Appliance Guru replied 1 year ago.

Yes on that unit they seem to sag.

Customer: replied 1 year ago.
If you are right shouldnt I see the boot move when the drain pump goes on?
Expert:  Appliance Guru replied 1 year ago.

Yes you would see it move or pull down in the center between the pump and outer tub.

Customer: replied 1 year ago.
I don't see much sag in that boot.
Customer: replied 1 year ago.
If I don't see that then the problem is probably in the board?
Expert:  Appliance Guru replied 1 year ago.

Yes I would say so, I would watch it closely when it does fail and see if the pump is coming on and running at all before that code comes up, if it does not then I would say the board is the issue.

Customer: replied 1 year ago.
Does the pump come on between wash and rinse cycle or just after rinse cycle?
Expert:  Appliance Guru replied 1 year ago.

If the pump is coming on and you have replaced it, either the drain hose is blocked or something is with the boot that is about it. I would remove the sump boot from the outer tub and check everything good for anything blocked.

Customer: replied 1 year ago.
I just took the boot off - nothing blocking or in it.
Expert:  Appliance Guru replied 1 year ago.

OK then double check the drain hose itself if that is good give it a try again, maybe duct tape the sump boot around so it keeps its shape for a test cycle and try it out and see what happens./

Customer: replied 1 year ago.
Should the tube from the pump attached to the drain hose have a little black piece on the end? It probably lets water out but not back in. I will try what you just suggested tomorrow, I am tired.
Expert:  Appliance Guru replied 1 year ago.

Yes it should have the check valve flapper on it correct. Yes I am tired as well...all I ask is please rate my service before leaving and you can then get directly back to me tomorrow for followup!
