Duet Washer Leaking

The most common cause of a Duet washer leaking is a hole in the washers door boot / bellows. However, a leak can come from many of the washer's parts. the best way is to narrow your problem down… is it leaking all the time, even when the washer is off? (valve or water supply) or only when the washer is running? (hose, drain pump, door boot / bellows) Visually inspect the washer for the source of the leak… be careful of moving parts that may remove your parts!

Duet Washer Vibration

1. Make sure your Duet washer is on solid footing… can you rock the washer by pressing on one of the corners.(adjust the washer legs)
2. Does the washer go out of balance EMPTY during a Duet Washer Quick Diagnostic Test? No => What if you have a heavy load of like items (all towels) on a short normal cycle? If it can balance an all towel load, your problem is probably load related. (Read the users manual) If it is off balance empty or the all towel load went off balance move to step #3.
3. Press down on the inner drum and feel for a popping movement (The inner drum support may be broken… this is bad) Try rotating the drum a few degrees and try several times… the inner and outer drums should move together as a unit. Sometimes the three point support that suspends the inner drum inside the outer drum can crack. If there is movement you may need a new inner wash drum.
4. Unplug the washer and remove the back panel to check the tub shocks. They should all be attached.
5. If all that checks out your probably safe to replace the washer's shocks.

Duet Washer Not Cleaning Well

Your washer can get extremely nasty inside in places you can't see. Try leaving the door open a crack when the washer is not in use and make sure to use the Clean washer cycle from time to time. Run a Duet Washer Quick Diagnostic Test and make sure that the washer is mechanically working correctly. If it is then you may want to try a different detergent.

Duet Washer Won't Drain

The most common Duet washer problem

1. Unplug the washer for 30 seconds to attempt to reset the Duet washer control.
2. Enter the Duet Washer Diagnostic Mode and check for error codes.
3. If your Duet washer has an F9E1 or SUDS error code (long drain) you may want to skip passed all the fill steps to step C07 (to test the drain pump.) This will hopefully keep your beloved Duet washer from filling with more water that it can't drain. You can't skip C00 (Door Lock) and C03 (Dispensing System) and go strait to testing the drain pump.
4. The best way I have found to deal with the water when your washer's drain pump isn't working is to use a shop-vac and pull from the drain hose. If that works the your pump is highly suspect. If it doesn't work then you almost certainly have a clog in your Duet washer's drain system and the pump may be fine.
5. If you can hear that the pump is trying to drain, you know it's getting power from the Duet control like it should. Remove the pump and check for blockages. If the drain pump is not even trying to run you will need to check power supply to the pump for 120VAC when it should be draining. at the Duet control's DP2 connection and at the drain pump.
