Whirlpool Duet washer

[jeff_adelphi]

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.
