LOVE IT!!!!.........EXCELLENT
what so many of these low water machines need.....
and of course questions galore.....
first....how are you powering the pump?....especially to only run during the agitation phase.....
and where did you get that port?

Completely brilliant! I never cease to be amazed by the resourcefulness and technical abilities of people in the AW family. I think every modern, large capacity front loader should have a recirculation jet.
WOW!
I want this! How'd you do it?

Spill it!
How did you wire the recirc pump in without the board thinking there was something wrong and giving you a fault code???

Very impressive Jeff, I love it! Congrats, what electrical signal are you using to control the pump on and off?
Duet!
Wow Jeff that is so awesome - Love it!

The only way I could imagine that working would be makeing it waterlevel depended. So ones the level is reached, the pump turns on. But FL'S don't use a 1-level sensor, so the direct connection is out of the way.
Next, he could have coupled it to the door-look. But than, it would run througout the cycle.
Next, he could have connected it to the waterinlet valves. But again, it would run throughout the spins.
Next, he could use kind of switch that turns the recirc of in the moment the drainpum turns on. I don't know the exactly spincycle configuration, but if it does any spin-part (redistribution or as LG during spin) with the pump turned of, this would work not again.
So, I think he used one switch that allows the current to flow as long as the door is shut, one that stops the current as the valves are powered and one that does the same for the pump. Than, only the fillstage would cause to low waterlevel for the pump not to work, and as this phase is rather short, it wouldn't mean any damage to the pump. And the current is pulled from the main power cord. Could this work?

YAY JEFF! Thanks for sharing your genius.
My guess would be Jeff could have put an electrical relay in series with the drain pump, so when the drain pump turns ON the relay turns the recirculation pump OFF. Then when the drain pump turns OFF the recirculation pump turns ON and sprays. This way the spray only runs when the machine is filling or tumbling for wash and rinse.
That wouldn't work if the Duet cycles the drain pump on and off during spin cycles, but I don't know that.

Good thinking - - -
henene4 and Robert, You went thru the same problems I did in making this work. My solution is to connect the pump to the door lock switch so it can only pump when the washer is locked and running. Then connected a relay to the drain pump circuit that stops the recirculation pump when drain pump is on. But, during some drain and spin cycles, the drain pump does stop and start, so I added a one minute delay timer to prevent the recirculation pump from running during these drain pump pauses.
The pump I used is dishwasher drain pump and spray port is made from a 3/4" PVC bulkhead fitting. I sawed off the end of a 1" PVC pipe cap and epoxyed it to the bulkhead fitting. Then I cut the slot in the cap, it took 2 tries to get the angle of spray right. The first try washed the window but didn't hit the clothes.

Oh, and where is it pulling power? I mean, where do you get the current from?

Looks Great Jeff, but do you have any problem with the added pump overheating, most of these little drain pumps are intermittent duty, most DW drain pumps won't run more than about ten minutes.

Power in supplied thru the door lock switch, when the door is locked the switch is closed. This is the main power supply to all washer parts as well as my added pump.
So far I have not had any overheating problems with the pump motor. It's a 30 watt motor, and it's duty cycle is rated 15 min. on / 45 min. off. It does get to cool down during drain and spin.
My Sanitary stain treat wash runs for 1:00 to 1:30 hours alone. wish Maytag had not discontinued the Maxima 9000 with the recirculating pump.
Where is the DW pump pulling the water from? Looks like you attached it to the drain pump. Is there some unused outlet?
How did you manage to cut into the gasket without risking the cut becoming larger (being torn open) during OB spin cycles?
I wonder if you could have wired the recirc in line with the pressure switch so that it comes on once the minimum water level is satisfied.

Bob, when did Maytag have recirculation? I thought PowerSpray would only inject liquid detergent mixed with water via that extra nozzle. Some main wash cycles can take almost three hours one mine. The pump can shut off for up to 15 minutes during redistribution before the final spin.

To connect the extra pump, I drilled a hole in the side of the pump protector housing and epoxyed in a 3/4" PVC tube. What would we do without J-B Weld epoxy!
If you look at the pump protector screen you can see it was made to have a second pump, but no outlet was provided in the housing.
Where the outlet connects to the boot, I cut a hole and the bulkhead fitting clamps the boot in place. The attachment point is near the cabinet side of the boot, so there isn't much movement at that point.
I thought about a connection to the water level switch, but it's a 4 level switch.
It might be a better way to controll the pump and get rid of the 1 minute delay.
Amazing Jeff, I I love how ingenious all this is.
As mentioned above, you could use one simple relay and attach it to the lowest water level terminal on the water level switch, that way the pump will only run when there is a minimum amount of water in the tub. Recirculation will continue to run in the drain cycle until the water level switch completely resets, then it would stop and the machine would finish draining. I can't see how that would be an issue as far as I can tell, just like a Whirlpool manual clean filter ran during the first half of drain! I assume the water level switch will trip on always the lowest level, whether the computer is looking for it's signal or not.[this post was last edited: 1/12/2014-19:56]

Jeff,
Nice work! Looks like a clean installation and appears to work well from the video. Let me know if you need any custom nozzle work done.
Have you noticed any performance differences yet or is it still too early to tell?

Great work Jeff!
That is a fantastic modification. Another great LeFever mind at work! I would love to hear how it increases performance.
