My maytag neptune wash machine does not drain and spin clothes it

Washer bangs around in spin cycle and throws a DC or UC unballance code with cloths in the wash basket is that correct?

If so it's a Clutch issue.

If you want read more about what I feel is your issue read this post Maytag Neptune load unbalance

If the clutch fails the first thing noticed is a UC or DC error displayed and there is no drain or spin.

If you are seeing the above error and having a problem with spin and drain then the most likely cause of this is the clutch. The clutch fails to lock down the spinners and the basket is unable to go into spin and without a 90 RPM there is no drain.

Replace the clutch.

ITS POSSABLE ITS NOT PUMPING FAST ENOUGH. CHECK THE DRAIN HOSE AND MAKE SURE IT HAS NO KINK. IF THATS OK IT MAY HAVE A BUILDUP OF SOAP. RUN A EMPTY CYCLE WITH NO SOAP. IF THAT DONT WORK YOU NEED A REPIARMAN TO CLEAN OR REPLACE THE PUMP.

Pump out time of 40 seconds sounds good.

No ND error code and you spin up to 850RPM which is max for the machine.

You have no standing water in the wash basket.... I'm scratching my head.

Could you do a Spin Only cycle with that same wet wash load and set the SPIN for Max Extract. After you start the Spin Only cycle put the machine in Service Mode and watch the RPM range. This cycle sets the display to 12 minutes. Let’s see if the wash load remains wet and what max RPM is reached.

""Maybe the pump is not turning on during the spin cycle?"" You have no standing water in the wash basket correct? I feel the pump is turning on or you would have standing water in the wash basket and the pressure switch would have never indicated an empty condition (Low Level pressure switch contacts) to the Control Board. The Control Board would have stopped the wash cycle with a ND for no drain error code.

The pump in the spin cycle will turn on a number of times see if you hear turn on in a Spin Only cycle

I just ran a Spin Only light wash load with about 5 gallons of water in the wash basket. Timer went to 12 min. I toggled into Service Mode to watch wash basket RPM. At about the 5 Min mark (toggle in and out of Service Mode) the wash basket reached 850RPM then a few minutes later it stepped down to 830RPM to end of Spin Only Cycle. You don’t have a water valve stuck open or you would flood/over flow of the machine. Did you here the drain pump turn on several times during the Spin Only cycle?

there are 2 wires going back to the board. They connect to a blue harness. Make sure their is continuity thru the harness. It connects to 3 out of balance swithches. Also check to see if lock light comes on.

Continuous Unbalanced Circuit. Improper signal from Tub Displacement Sensor.
Wet Clothes • Very small clothes loads can cause unbalanced loads - add additional towels. • Excessive suds may have been present. • Check Tub Displacement Sensor connection and main harness connector at machine control board. • Check Tub Displacement Sensor for 0 to 3.0 Volts DC output voltage between ground and the board input. Check for 12 Volts DC input voltage between the ground and the board output. Only check for voltage at the Tub Displacement Sensor. Do not perform a continuity check. See Tub Displacement Diagnostics • Excessive motion was detected in spin Run Quick Spin Test with an empty tub to check Tub Displacement Sensor and machine control board. • Check for restricted drain system.

DC means: Unbalanced load prevented the washer from
spinning.

This happened to me when i was washing a single shirt (red shirt, first time washing so i did it seperately so it wouldnt bleed into other clothes)

So i set the washer to "drain", waited for the door to open, and wrung the shirt out by hand. Next load it worked properly.

A dc error means that the clothing is not being distributed properly in the basket. This usually happens when the machine is lightly loaded. If the load seems o.k. then the problem is probably with the sensor at the side of the basket.

either balance load sensor or machine failing to drain in the allocated time, check pump/filter for blockage
