I have a maytag neptune washer model# mah300aww.

it could be a balance problem. Most machines are programmed to abort fast spin if the drum is unbalanced. This can be caused by too much in there, or possible the contents have clumped together somehow. Try a spin cycle only with an empty machine and see if it reaches full spin

It sounds like the "repaired" main control board is still the issue with it being intermittent.

replace timer. 30 to 50% of value of new machine

This is usually the wax motor in the door switch. It's inexpensive and easy to replace. Here are a couple links that should help http://appliancehelponline.com/frontloadmaytagdoor.html

cheak your tube if there is a nail or an object is stuck in one of the holes

hi there ..sounds like your appliance is not spinning at all........(a) check if your drain pump is working correctly..(simply fill water and turn to drain)..(b) possiblity that the clutch drive mechanism is badly worn and needs replaced

It sounds like the bearings in the rear outer tub have gone out. This is caused from using powder soap. ( It also happens with liquid sometimes) This is a common problem with front load washers. This is a also a very costly fix. You have to replace the whole outer tub assembly. To get an exact cost just call your local service tech and tell them what your problem is and they can give an idea how much it will be.

sounds like your control board is going out. when control board is replaced you want to replace wax motor as well

Problem solved by ourselves! It was NOT in the circuit board (brain) of the machine. It was NOT in the door locking assembly as others would lead us to believe. It WAS the on/off switch on the control panel--part number 22002560 - a $22.00 problem fix.

Hi Mcbride2

It could be one of 2 things. 1 the belt. or 2 the main seal and bearing. i recomnd to get a tech just to make suer.
