MAV7450AWW Maytag Washer - Instructions

Turned off the water supply. Removed clothing and bailed out water fro tub. Removed back access panel. Turned washer over to access the bottom and removed drive belt by turning the large pulley attached the drum while pulling the belt over the pulley. Next remove the two hoses attached to the pump, remove the screws holding the pump on and remove the pump. Replace the pump by reversing the procedure, as for replacing the drive belt, place the belt on the motor and pump first and start it on the larger pulley and hold it on while you turn the pulley, it will pull the motor adjustment as you turn and when fully in the pulley it will be properly adjusted. Then replace the access panel, turn the washer upright, push back in place, turn on the water supply and replace the drain hose. Back in business. For me, while I was waiting for the new pump to arrive, I took the time to remove the agitator and tub and give it a good cleaning inside and out, but that's me.

Pump is readily accessible at the back of the machine by taking off the access cover. First step is to disconnect power and remove drive belt off tub pulley which is the largest in the center - the takeup is in the drive motor mount but it seems easier to turn the larger pulley and wind the belt off. There are three 3/8 hex mount screws fastening the pump to the washer base and two hose spring clamps attaching the tub drain hose and outlet drain hose to the pump. Follow the directions in the utube video which is the best (most others don't give detailed directions and best method). The only caution I would give is that there is some water in the drain hoses so be prepared to mop it up with sponge and bucket or have some towels available. Install new pump (loose assemble two visible screws to locate pump and then loose assemble far side blind screw and tighten all 3),replace hoses snug to stops and assemble clamps, replace access panel and replace drive belt and plug washer back in.

Brought unit out to garage so I would have room to work on it. Popped the top off, removed two screws to remove the front panel, removed back panel also, since there was no way I was going to the trouble of dis-assembly to get to the snubber without changing those 6 springs also - and you HAVE to remove the back cover to access all 6 springs.Removed belt and level and drain hoses- tub came right out. Loosened those 6 screws without removing them and pulled old snubber out- very straight-forward. Spent 10 minutes just comparing the old and new snubbers- I saw that there's a "ridge" around the inside of the new part that is gone on the old snubber. Sprinkled some corn starch at base of unit where the new snubber will fit (Great Idea someone had!) After everything was re-assmbled, I noticed the tub was now nice and tight when I grabbed it to move it. Before, it took no effort AT ALL to move it all around. Did a test load with some laundry the wife had stacked on the drier. Imagine my disappointment when I heard loud knocking inside when it started to agitate, but not while it spun!
Got all my tools back out and took the wet laundry out to take it all apart again- found the wife's heavy glass vase had been hidden in one of the towels. Re-tested- everything works GREAT!So far I've changed the drum seal (hardest) and the waterpump (easiest)- thi springs and snubber was alsmost as easy as the pump.
Above average shipping from Parts Select also- very helpful and efficient people on the phones.

Followed the excellent utube instructions you provide. Piece of cake when I followed the video. The rear springs became much more difficult because my model does not have rear access panel. They were the only stuggle. Thank you for doing the repair videos

Shut-off water + power.With the putty knive; slide it under the front of the top to push back on the spring clips.The top will lift easily and it is hinged.The Water inlet unit in the back has a plastic cover.Remove carefully.One screw holds the unit in place. Remove and the the unit will slide out to the left. It's now easy to disconnect the hoses from the unit. The wiring to the coils is color coded,take note for proper reconnecting. Remove stakon connectors from the valve coils. Careful, do not pull on the wire but wiggle it of the coil connection.Pay attention to the routing of the wire harness. Also the kit comes with a clear plastic splash shield. make sure the new goes in the right place.Now the old water inlet valve can be removed from the metal bracket.One srew.Assembly goes in reverse

Removed the inner basket and outer tub to replace the gasket and rubber seal. just had to remove about a dozen screws to get it out.

Tipped the machine up to replace the belt.
The noise didn't go away at first. I decided to spray all the pulleys with some silicone spray, that did the trick.

Removing and installing the pump is theoretically easy, as everyone on this site has said so far. Just remove three hex-shaped screws, loosen drive belt and remove pump, then install new one using the same steps in reverse order. The trick is getting the screws off and on--they do not have slots for a screwdriver and there is not room around them for a socket wrench or pliers. I probable spent over an hour just on removing/replacing these screws and have many bruises to show for it. I ended up attaching a vice grips on the tips of the screws underneath the washing machine and screwing them out that way. And replacing the drive belt was horrifically difficult--that's where the other hour went. The devil was definitely in the details! If anyone had told me what I would have to go through to make this repair, I would have called a repairman. And I am an extremely handy person--I do stuff like repairs all the time, so it is unusual for me to say this. The good news is that the new pump works and the washer is back in commission.

As described in video; however, the video does not match the model I repaired. Most stuff is the same. Hardest thing to do was installing the new springs on the back of the tub (2 of them).

Analyzed reason for hot water being turned on when only cold water was set. Determined solenoids were functioning correctly using volt/ohm meter and continued working backwards through the electrical circuit. Upon testing resistance level of 4 button switch was able to determine the switch was functioning intermittently. Validated by checking the power and determined voltage was being transferred to more than 1 connector, which was incorrect. Replaced switch with known good switch (validated new switch was good by checking resistivity) prior to installing. Installed switch and ran washer through cold cycle, hot cycle, and warm cycle to validate fix.

Removed 5 screws on back of the control tower.

removed the temperature control board and replaced with new board.

I took the back plate off, which consisted of 3 phillips screws and 2 hex head screws. Than I removed 2 plugs; one from washer timer and one to the board that is clipped on the back of the washer timer. The washer timer has to be slid a little to the right, if your facing the back of the machine, than pulled up. It came out rather easy.
I put the new washer timer in, back tracing how I had removed it and ran 5 loads of colored wash with no problems.

Replaced timer. Removed cover, disconnected wiring brackets, replaced new component & reassembled.

I removed the old pump put the new one in its place. In twenty minutes i was ready to was clothes. It was so quite i thought something was wrong. I received the part in three days the timing was great.

Pop the cap off the agitator/auger no tools needed. Once removed select a socket and a socket exstension. remove the screw amd pull off the part. Make sure to save the washer that may be still attached to the inside of the agitator. install the new agitator using the existing screw and washer. Takes about 15 minutes.

After taking the motor off (it looked loose to me!) and stripping out the bolts on it, then finding that the bolts holding the motor were permanently affixed to the motor (and they were an odd size not available at the hardware store), I drilled the bolts out and put in new ones (on the motor) and re-affixed the same. I still had a problem. I then went online and found that most people had problems with the water pump. I looked at the pulley on the water pump and found that the inner shims had slipped out on a permanent part (and could not be put back in with the basic tools I had on hand). I ordered the pump online, and replaced the same. Took about 30 minutes after I found the real problem and got the parts in. My pump had a permanent metal disc on the bottom which did not come with the new pump, but the new pump fit without it. Machine works fine now.
