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

Jeff, very well done. Thanks for making the video. It was nice to see a peek of your green Philco too. |

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. |

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. |

Hi Jeff, Congratulations for your work is fantastic. I want to have more information about the parts you used cause I have a Duet and want to try to do the same. I live in Brazil but I can parts at Ebay. |

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

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. |

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. |

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 01/12/2014 at 19:56 |
