Washer Flashing Error Code ND; door won't open after turning washer off

Are you sure this is not an nd and not an np flash code? If so then the code stands for no drain, likely something is clogging the washer pump inlet.

Most likely pump is blocked or broken.

Hello zabbster - Typically the DR or DO error code indicates that the door switch is not closed. Make sure that the door lock is completely closed. If the door is closed, make sure the door latch is not broken. If the latch is broken, you may possibly need to replace the door lock switch.

answer of puk code

Unplug the washer. Then plug it back in and press the button that turns it off. This should unlock the door. Same thing happened on mine and there was a kink in the drain hose. Once I unkinked the hose, unplugged it, plugged it back in, turned it off, then I was able to run a drain & spin cycle to get the water out of the load that was in the washer. I then ran a full wash cycle (they'd gotten stuck in the first drain & spin cycle of a wash) and everything seems to be fine now.

Press the cancel button twice to cancel the error code. There should be an error code flashing -- for example 'F02'.

Hello there and welcome to fixya
From what you're describing it sounds like the drain pump is blocked. The nd error code indicates "no drain". If the unit can't drain it won't spin. You're going to have to slide the washer out far enough to remove the rear panel; be careful not to damage the floor. Once you get the rear panel off you will see the pump. Be sure to have plenty of towels & a small container to catch water. I am sending you instructions from the service manual to remove and replace the pump. Another possibility is the drain line is blocked or something is stuck in the tub to pump hose.

Hello first try unplugging the machine for 7 minutes if this doesn't then allow you to open the door then you can manually release the door lock by taking off the dispenser assebly holder (bezel) and pulling on the door lock release cord you will find inside. Also as far as the nP I think the erro your seeing is ND which is no drain in which you can click this link

Hello,
The ND error code means NO DRAIN, why it comes up is because the computer thinks that within the normal times it takes to drain the water from the tub it hasnt drained in that time.
Things that will cause it to not drain in the normal time is oversudsing becuase too much detergent was added.
Or something such as lint in the drain pump filter screen restricting the water flow into the pump

If your washer is beeping, and the display is flashing "Nd", your debris filter may be clogged. To check for a clogged debris filter, goto back of machine, look for little door at bottom remove cover and remove filter and clean
