Maytag MLG2000AWW Will not complete wash cycle
Posted 28 March 2009 - 08:07 AM
Turn the timer to Heavy or light, press the start button. ON light illuminates. Washer begins to fill. After filling washer ON light remains on. Long pause with little to no activity. Motor will turn and rotate the drum for a brief period in one direction then stop. After another pause. drum will rotate in opposite direction. After doing this for a while unit will typically shut itself off before reaching a rinse cycle. If you manually turn the timer the unit will drain and refill properly, but will never reach the spin cycle. The door does lock in the proper stages and the lamp illuminates.
I'm sure there is more details you want so let me know.

Water pressure to the wall taps is good, but I will double check how well it fills in the washer its self. It has always seemed to sound like it was filling well, but I can't rule out that there might be some blockage in the valves, etc.
What is the best way to check the pressure in the unit?

I forgot to mention, that when I received this unit, it came with a new washer timer (the last owner thought that might have been the problem, but never bothered to install it). So, I went ahead and installed it, and nothing changed, so it would appear the timer itself is not the culprit.
I was looking at the service manual that you guys provided, and saw on page 3-1 a troubleshooting tip discussing a condition where the machine shuts off after 5 minutes. It leads you to look for a communication issue between the timer and main control board.
What do you guys think?

I am going to remove the top panel of the cabinet to take a look at the control board this evening. If there is anything additional you thing I should check let me know.

** Water fill- If the unit sees one fill take longer then 6 minutes, or combined fills taking longer then 12, it shuts off until the start is pressed. Clean the screens at the end of the hose at both ends! Faucet end should have a screen washer to catch the gunk.
** Timer motor must advance- If the timer does not advance to a new incriminate in any 5 minute time, the unit will shut off. The timer motor receives a pulse of L1 for about 5-10 seconds from the board every couple of minutes. It is not a constant feed. This is what the quote you pasted from the Service Manual is referring too. Usually, if this is the case, the unit will not advance in any location.
** Timer inputs- There are 4 timer inputs to the board that tell the board via L1, 24VDC or a combination of the two what cycle it is in (Fill, Rinse, Wash, Spin, Etc.). If the board fails to see a input or combination of inputs it recognizes, it will shut off. This can be caused by a bad timer (you tried one so throw that out) or loose connections at the board on these inputs (much more common). Now not only will the unit stop if it does not see the correct input, it will not start until it does. This does not sound like what you are describing.
** Motor inputs- Torque Tach return signal. This will cause you unit to shut down if the upper board ever' fails to see the signals back from the motor control. If it never sees the signal as in a bad board, it will only run in 5-20 second intervals. This is not your case, but a loose connection can intermittently loose the signal causing the unit to shut down.
Before changing out a part if nothing is obvious, clean the water supply and tighten all the connections that keep the unit running.

This time around I wasn't getting any action out of the motor, all i could get it to do was fill and drain. This is really starting to bug me, as it seems to be digressing.

Also check your tub displacement switch at the front bottom of the tub, the wires may have pulled out of the switch, if this switch doesn't close, the machine control board thinks the load is unbalanced, and will try a few times to redistribute the load before going into high speed spin. If it doesn't succeed, it will give up and shut the machine off.

Now I do this with the machine live... I DO NOT RECOMMEND it because if you touch the mcu you will go OUUUUCCHHHH! if you do use extreme caution as to not touch any part of the MCU but the white connector.
assuming you have to replaced the conversion kit, your mcu should look like this:
see dat derrr blue, red yella and whhhhite wire??? pull on dat... DONT TOUCH THE METAL!
if your board does not look like this, then it should like this:

In the mean time, this is what my Motor Control looks like.
