WFW9400SB02 Whirlpool Washer - Instructions

Remove the lower front cover there are three small torx type screw. The pump is the very first thing you see. Have a wet and dry Vac available you will need it. The drain pump and the drain lines contain a lot of water. Unscrew the big white drain plug at the pump and clean up the water, remove the front small mounting screw and disconnect the two hoses in the back of the pump with pliers and follow the pre-printed steps in reverse. If your machine is more than six years old you will have to use a utility knife and remove a piece of plastic on the electrical connector that is from the washer wiring, if you force the connection on it will brake, look at the connection and the plug and attempt to plug it in before you install the pump. It is easy just be-aware of the connector.

I found a you tube video with step by step instructions. Very easy to follow. Repair would have been quicker had my kids not been at home. I had to have my boyfriend help me put on the outer bellow spring clamp, as I was not strong enough. Washer works great.

Removed back panel,unscrewed the nut on the pulley.Removed pulley and belt. Reassembled.

To verify it was the motor making the noise not the drum bearing I removed the belt and rotated both by hand to see which one made naoise - then I ordered the motor.
To install the motor remove rear panel, slip belt off, remove 1 bolt holding motor in, carefully slide motor towards you until pivits disengage. Wires are ling enough to set motor on bottom of washer and rotate for easier access to connector. Install motor in reverse sequence.

1-Unplug washer
2-Remove the bottom of the front washer cover 3 screws
3-Locate pump and loosen pump drain cover turn to left just a little enough for water to start draining.
4- Suck-up water with wet/ dry vac. Remove 1 screw holding pump.
5- Flip pump electrical cover up and disconnect wiring from pump.
6- Remove 2 hose clamps. The outlet was not to hard to remove, but the intake was not easy to get the pliers on.
7- Install new pump. See instruction to install. I didn't have to remove any ribs to install the connector as in the instruction sheet that came with the new pump. Also I didn't think it was very clear instruction.
8- Last installing the spring clamps. The outlet went okay, but the inlet I never could get on. I could not get the pliers on the clamp. I fooled around at least 20 min. trying to get the clamp on. I went out and bought a 3/4 to 1 3/4 stainless hose clamp with the worm drive design. That is what took so long.You may want to get new hose clamps before starting.
Other wise I did okay.

1) Removed back of washer
2) Removed nut holding pulley
3) Pulled pulley off shaft
4) Put new pulley on shaft
5) Replaced and tightened nut
6) Replaced belt on pulley
7) Replaced back panel
7) Washed pile of laundry

remove 3 screws of top panel at rear. slide top to rear 1/2 inch and lift up. disconnect wire to flometer, remove clamps on hoses and remove, reverse to install. did not fix problem. ck'd screens at fill valves. ordered new fill valves--problem solved. solenoids must not have been opening up all the way.

I followed the repair blog by the poster most liked...

Somehow a bobby pin got into the drain pump housing. When it started to drain, the pin was rammed through the housing.Extremely easy to remove and replace. No special skills needed. Whirlpool did a good job in making it idiot proof. Unpacking the part took longer than installing it. Don't be afraid to do this repair. If you own a pair of pliers and a screwdriver,you can do it.

Disconnected 2 hoses and 1 screw and remove3d the old pump and reversed the proceedure to install the new pump.A piece of cake. Thanks

I first had to take off the back and the top to get to the pulley and the belt. The pulley had woobled so much that it had worn out the center nad it would no longer hold to the post in the tub. It also had cut into the back of the tub about a 1/4 to 1/2 inch. I unscrewed the nut holding the pulley and removed it. I then took a knife and trimmed the rough edges off the back of the tub to make it smooth. I then smoothed out the end of the post that the pulley fits on so the new pulley would fit. I tightned the nut and put the belt on the motor drive shaft and Used a robo grip to hold the belt as I turned it onto the pulley. I but the back and top back on and that was it.

Serviceman had previously replaced the hot and cold inlet valves, but the low pressure error persisted. Rather than cough up another $130 for the serviceman to return, plus parts and time, I decided to order the replacement flowmeter from PartSelect.

Unplug power and turn off water. Top of machine comes off by removing three screws at top rear; use socket, spanner or T20 driver. Unplug electric sensor from flowmeter. Old unit is removed, and new one connected to water line by squeezing spring-clips with a pair of flat nose pliers. Reconnect electric sensor.

Great move, easy, and saved myself the thick end of $200.

I romoved the front of the washer access panel. I then used the pliers to remove the clamps from the old hose and to replaceit with the new one.

After removing the Top Cover and back cover by removing the 3 screws for the top and 10 screws on the back cover to expose the interior of the machine. Remove the rubber hose that was attached to the bottom of pressure switch. Pushed gently upward on the pressure switch until it popped out. Gently press down on the 2 small tabs on the plug and then gently pull the plug out. Placed new pressure switch in place, plugged the connector back into the switch. Also doubled checked the hose to ensure that the tubing has not rubbed a hole it from rubbing on the concrete counter balance. If yes then remove the tube from the bottom of the washer and replace with approximately 2 feet of 3/16 inner diameter/1/4 outer diameter tubing. Attach the new tubing to the bottom of the washer port and the pressure switch. Attach the new tub to the water discharge hose using tie wraps or electrical tape to ensure not to occur again.

First and foremost, I usually call a real man to come do a job like this, but after reading the repair stories, I gave it a shot. Very, very easy. Pop of the bottom panel off (three torx screws), drain the water out of the tub (if any), and just follow the directions in the box. Anyone can do this one.
