Hello LPeck, This is a pretty common issue with all front loading washers. Typically it has to do with the door bellows (gasket) that seals the door to the washer cabinet.
First, look very carefully at the gasket all the way around, using a flashlight. Pay close attention to the area where the water flows into the washer. This is usually located on the upper part of the gasket and sometimes the water inlet port gets the gasket moved out of place and when the water is flowing into the washer, it can leak outside of the gasket. Make sure that the gasket is properly located around the water inlet port and that the gasket does NOT extend past the water nozzle.
The other thing to do is again look very carefully at the entire gasket for small cuts or tears that might be allowing water to leak out. Even a small cut can allow alot of water to leak out of the wash tub, so carefully push/pull the gasket with your fingers while shining the flashlight onto it.
In almost all cases, it is a cut or torn gasket that is the source of the leak.
This is an easy self-service repair, only requiring a few basic hand tools to remove the gasket bellows from the washer cabinet and inner wash tub. Just fold the back lip from the washer cabinet and you'll see the retainer wire that holds the bellows onto the cabinet. With that removed, you can then slip the bellows gasker off the cabinet lip and see and get at the inner wash tub retaining clamp. Typically held on with a large diameter hose clamp. Remove that and you're ready to install the new one in the reverse order.
Just be sure to let the new gasket lay out to help get most of the kinks out of it, from being in the small shipping box, and install it slowly and carefully, so not to put any cuts in it.
This will save you around $150 +/- instead of having a service tech do the installation/repair for you.
If you want to see and order the part yourself, you can go to the following link to see the gasket and how it is installed. You can order it online from sears, or any place you wish.
Hope you find this Very Helpful and best regards!
