We replaced the machine control board. Machine continues to malfunction as before- hot water valve constantly open, and timer won't advance.
Answer Jerome, There are a couple of other things to check first. Remove the slanted panel across the top of the washer, on each side of the tub, you'll find multi plug connectors(1 on each side) Disconnect the upper harness and check both connectors for loose or shorted wires or pins, and the plastic connector openings for discoloration, indicating a possible short. At the machine control board, you'll need to check for a 24 Volt DC circuit at conn.P7 pin 7 (ylw wire) for 24VDC to the black wire on the relay,and conn. P7 pin 8 (pnk wire) for the same while the unit is filling/washing. If you have no 24 VDC or Low VDC that would indicate a bad timer input contact. The hot water does stop flowing when you turn the timer off, correct. Hope this is a help to you, Good Luck

I want to be sure that this item is what I need. Could you tell me if it is so? Thanks, Giuseppe
Answer Hello Giuseppe,
If you could please list the symptoms the unit is giving, we can determine if the machine control board would be the cause of your problem or not.
WASHER KEEPS SHUTTING DOWN AFTER ABOUT 5 MIN
i CAN PUSH START BUTTON TO STARTBUT THAT HAS TO BE DONE REPEATEDLY FOR ONE LOAD. I REPLACED TIMER NOT THE PROBLEM.
Answer Jane, Faulty timers on this style unit are a rare occurrence. Your first check needs to be at the water valve 22002437 and hose screens 12001413. and the water levels switch 22002921 and air dome hose 22002483 for clogs and debris. If the washer machine control board(up inside the dryer cabinet) does not see a change in the water level switch within a certain amount of time, or it doesn't see the motor start to run in either direction, the control board assumes the washer is overfilling and shuts itself off, to elinminate a possible flood. If you have a slow fill due to sediment in the screens, or debris in the air dome hose, or a faulty water level switch, the washer will start and fill for 3 to 5 minutes, then shut down.
We have replaced the control board on our washer and now it will not spin the clothes out completely. When I look at the old board there is a black mark on the 1st metal bar towards the right of the board (R11 ??). Should we replace the wax motor?
Answer Lucy, You're thinking of a different model machine (MAH 3000,4000 or 5500) The machine control board for a MAH6700aww is dependent on the series number ( first two numbers of the serial number) in order to order the correct control.: series 10 =34001488 series 11-13 = 34001479 series14 and after = W10273828, You are on track, so don't give up. Good Luck and Thanks
I have the MLG2000AWW and it's about 10 years old. It has performed well over the 10 years with only a few problems. This one has me stumped. The washer suddenly will not spin. I have checked the balance circuit.. OK. I have checked the wax motor and made sure it is engaging the spin switch... OK... but we still have no spin. I've downloaded the manual and it says the control board. Is this what you expect as well? Is there anyway to visually inspect the control board to see if there is something wrong with it? Thanks!
Answer Rick, With your description, you need to check the "spin enable switch" on the door latch assembly 22002162. Once the washer is started in a spin cycle, the wax motor expands and the door is locked, with the red and yellow wire(s) disconnected, check the switch ternminals for a "closed" circuit, with the wires disconnected. Or check for 24 VDC into the switch on the red wire and 24 VDC out on the yellow wire. If the circuit and VDC voltage does not get transported up to the main control board, the washer will not spin. If all's OK, check for loose connections and wires at the multi plug connectors on both sides of the tub assembly, then go up and check the main control board in the right front corner of the dryer cabinet. Thanks and Good Luck
Do I try another control board? Ever had a bad, new control board? My original trouble shooting came up with "replace control board." (Machine stopped during wash, stopped at end of rinse 3, and usually did not spin. I could keep restarting and occassionally get through a complete wash and spin.) So, put in new control board. This gave me new problems: Machine stayed on for complete wash but did not attempt to spin and the machine would auto start when the timer was moved to a run position (line relay still closed but door light had gone out at end of wash). Door locked light and door light go out in different sequence than before. So, I replaced wax motor and timer, although not conviced I needed to. Neither changed anything. Rechecked out-of balance and door locked switches up to the control board. Checked motor and motor control board just because I am running out of things to check. Motor and motor control are the updated version and new 2 years ago. Try another control board????
Answer Jim, No, , your issue was not in the control board to begin with. Check and make sure you have the correct part installed, based on the model and serial number. Based on your post, the original issue would have been with the water level switch 22002921 , water supply at the faucets, fill valve 22002437 or air dome hose 22002483. When the main control runs a system check, during the cycle,if it doesn't see the proper circuit from the water level switch, it can result in a shut down of the washer. The control also "counts" the fill cycles, if it doesn't see the proper amount of fills for the cycle counts, it will shut down as well. Also check for any loose connections at the multiplug connectors, mounted to the cabinet frame on each side of the outer tub, and the drain pump for operation as well. Good Luck and Thanks
Our washer just started not draining. Stuck in the wash cycle. Wont allow water in or water out. When you hit drain button, just sounds like its grinding...help???
Answer Phillip, You'll need to be pretty careful, you'll need to move the washer away from the wall so you can access the drain pump, and check for an article(s) stuck in the pump or a defective pump motor 25001052. You can access the pump from the front of the unit, but thats a bit more involved. here are the basic instructions, "PUMP ASSEMBLY The pump assembly is mounted to the right rear area of the base.
REMOVAL 1. Disconnect power to the unit. 2. Spread a towel below the drain hoses prior to loosening the hose clamps. This will catch any residual water left in the hoses and sump area.3. Remove the hose clamps and hoses from the pump. 4. Remove the wiring harness from the pump motor terminals. 5. Rotate the pump assembly in a counterclockwise direction. The support legs of the pump are slotted to engage in keyed slots in the base. Reverse the steps to remount the pump." Good Luck and Thanks
