If the TIMER stops in 'agitate' as well as the motor, three things come to mind. The wire fell off the normally-open contact of the fill switch or at the other end where it goes to the timer. The fill switch itself has failed. The timer contact for 'agitate' has failed.
There is no way the transmission could tell the timer not to run, so it's not that. |

No noise, no humming, it just stops filling, then stasis, no function in wash section of timer circle, it is as though there is an absence of electrical signal ? |

This is definitely an electrical problem.
Could be a burned timer contact, could also be a burned contact in the pressure switch, could also be a loose or burned off wire AT the timer or the pressure switch.
If the motor runs fine for spin it's not the motor. If it were the transmission you would be hearing and smelling fascinating things when it initially tried to agitate.
How handy are you with matters electrical? |

There is not a special wire for that and there really should be no need to remove the lower panel, EXCEPT that the wiring schematic is glued to front of the outer washtub! For your convenience I will print it below:

The first thing I would do would be to remove the BROWN wire from the water level switch.
Then I would jumper the two Yellow with Black stipe wires across the pressure switch. If the machine starts to agitate then it is this switch that is bad.
If nothing happens, then there is likely issue in the timer itself.

Thanks, Doc! I shall try to check stuff in my own feeble and bumbling way, hah?! |

Where is the lower end of the water level switch pressure hose ? Tub rear ? I removed the front panel and found the schematic on the floor in front of the tub. I could not see where the tube ends. I cannot find any parts diagrams. More to come |

I wonder if the switch/contacts on the motor itself are bad. If that is the case I don't believe those switches are still available. The experts will know. I suppose replacing the entire motor with switch contacts will be the fix. BOTH My A806 and and A712 have defective trannys and neither will agitate. :(

Seriously, folks, do you read the previous comments before you speculate on what needs to be done? If the motor contacts were bad the machine would neither spin NOR would it agitate when the pressure switch was jumpered.
Paul, you will need a replacement switch to begin with. New or used probably doesn't matter but you MIGHT get more life out of a new one. There is no need to find the other end of the pressure tube unless for some reason you have cracked or broken it removing the old switch. The pressure hose just slips onto the switch. The fact that it stops filling at the right spot tells me that the pressure hose is good.
Your ohm meter reading is most likely irrelevant unless you took it across the two terminals that were connected to the yellow/black wire and the gray wire with the tub FULL of water. Nonetheless, if it agitates by jumping these two terminals it's the switch.
I just emailed the parts list to you. |

Could the lack of spin be due to failed tub mounting stem and tub bearing assemblies? |
