I have a Maytag Legacy top load clothes washer model number SAV515DAWW. During the regular cycle it fills with water to the desired height but then does not go through the washing/agitation portion it stops when it should begin that section of the cycle. Turning the knob to the rinse section it starts back up drains and spins the load. I have not checked other cycles other than regular.

the possibility of it being the timer is most likely..as the rest of the cycles remain ok.. if you require a timer,you can get one here at this link..(click the link here) http://www.easyapplianceparts.com/AdvancedModelSearch.aspx?ModelNum=HAV4657EWW&mfgModelNum=&fkMfgID=1

SOURCE: maytag washer won't fill or agitate; only spins on cycle

sounds like you have a blown fuse. I dont have a schematic so I dont kno where you have to look to find it

SOURCE: Not fully agitating

2 things
First is that I assume this not to be a 1 piece agitator. If it was the whole thing should turn back n forth Make sure its top (nut) fastner is tight. Usually just push down slightly and turn Clockwise.

A sectioned agitator has a lower section separate fro the upper. The lower can be attached to the agitator shaft and will move back n forth but the top has teeth that engage 1 way and allow slippage when the agitator comes back the other way. This "ratchet" action (some whirlpool older models that i have seen) if it has teeth ground off or grease build up under the teeth can cause them to stop agitating and just kind of sit there.

Drain and remove the clothes,
Take the top by hand and try turn it back n forth see if bottom moves. If the top is slipping and the bottom stays put remove the top nut (turn Counter Clock Wise) and try remove the upper section. If you can get it off you may be able to see why its not turning, and get the part to fix it.

Please let me know if this helped you. Rate me with as high a mark as you can. thanks and good luck.

SOURCE: Upper portion of agitator not working

This is commonly attributed to worn agitator dogs. The following link explains:

The part number is included in the instructions I provided for you. You can find replacements at appliancepartspros.com for about $5.

If you have questions, please let me know. I hope this helps you.

NOTE: When re-installing the agitator, do not over tighten. This may damage the agitator and/or restrict its movement. Tighten until snug.
