Always wanted to add Roto-Spray recirculation to my Duet.

Water tube attachment at boot
Recirculation pump installed on the left side of pump protector
It Works!
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?
Added Roto-Spray To A Duet
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.
