Older Maytag Neptune won’t drain or spin. It washes then times out when trying to spin and I get nd error. I turn it off the door will stay locked for hours and it is still trying to spin when I turn it back on. It has been checked out by a repair man who could find nothing and suggested it is the control board which is no longer manufactured. Any suggestions? Mah8700aww

if you remove the oval cover in the back of the mach,you will find the pump.there are 2 hose clamps to remove.usually you will find change stuck in the pump.remove the screws on the bracket that holds down the pump and you can take the entire pump out...good luck

Maytag Appliances are ****!! Don't buy Maytag. Spent $2500.00 in 2005 on Maytag Neptune washer and dryer. They have been nothing but trouble. Washer has water running in tub constantly. Recall on ground and recall on footing. Dryer making loud noise when drying clothes.The Maytag man is dead and gone.

Same problem.  Water wouldn't drain, no trouble codes, door wouldn't unlock.  When the Rinse and Spin cycle or Drain cycle was selected all I got was a growling humm from the pump.  Clued in by the above postings I pulled the washer away from the wall, tipped it back so it leaned against the wall with the bottom fully exposed and removed the plastic panel covering the bottom (underneath - 4 screws) of the machine.  The small pump was just where these postings said it would be, top right of the bottom opening. Disconnect the two drain hoses from the pump. Mine were connected with hose clamps that I removed with just my thumb and fore-finger.  I had two quarters AND a nickel lodged inside the pump and was able to coax them out without removing the pump. Replaced the hoses and bottom panel, tipped upright and I was back in business - didn't even have to unplug (Its never a bad idea to do so) or disconnect the water hoses.  

• Total time spent: including searching for these posts and random dead-end trouble shooting - 1.5 hours.
  
• Tools: 1 Phillips screwdriver.

there is no "red string" on this specific model. Its really irritating that everyone is saying this when clearly no one can find a red string. Stop giving this advice. From what i can tell so far the release lever is inside the machine and to get to it you have to remove the front panel. My problem now is i cant get the top electronic panel off to get the front panel off... this machine is like a giant chinese handcuff!! I will never buy a maytag ever again!!

Hi from retired Englishman in SW France,
I would gently suggest as a first step that you clean the drain motor/pump lint tray/filter. So many 'faults' are caused by blocked filters and many machines will not even go to rinse or spin or release the door lock if there is any water still left inside.
Here are my complete and generic guidance notes for checking both the drain motor filter and the drain motor ;-0)
If you are unsure where the filter is, it is often behind the front lower (kick) panel (or in some machines at the rear in an awkward position!). These panels are either held on by (plasic) screws or will just pull off. Most filters are held in by a round cover/knob. Sometimes the filter will not come out with the cover and you will have to persuade it to come out to play.

REMOVE POWER AND ENSURE YOU HAVE A WATER RECEPTACLE/RAGS TO SOAK UP THE WATER WHICH IS BOUND TO POUR OUT (alternatively use a wet vac as sensibly suggested by VinnyB1234!)
It's surprising what people have found in theirs! It is always worthwhile checking it on a regular basis.
Now- whilst the filter is removed it is normally possible to see the drain motor and ensure it is not jammed by a foreign object such as a needle or a toothpick. It should be able to be turned by hand/finger- the power IS OFF!
At this point it is also possible to test if the motor works. No clothes or water in the machine, select a spin cycle and put the power back on. You should be able to see the motor turning at some point, possibly straight away. Using something suitable like a glove see if it is easy to briefly slow the motor down. If it is easy then the motor is malfunctioning.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!
