I purchased a GE Model WHDSR209DWW washer 16 months ago, and a 5-yr
warranty.

The laundry is on the second floor of the house, so the washer sits on a
plastic tray that has a drain in the middle leading to the basement should
there be a leak.

We noticed today after a wash there was about a 1/2 inch of water in the
tray under the washer, and if you move the agitator, you can hear there is
water in the machine under the tub.

I called for a warranty appointment today, but they can't come until Monday.

The warranty appointment scheduler (not a tech) said two common problems
with washer leaks are a loose drain hose connection at the bottom of the
back of the machine, and a loose or missing spring clip that is apparently
supposed to hold the drain line at a proper angle. They said if I don't
want to wait until Monday and the problem is one of these two things, to
tighten the screws to the drain line connection, or they can ship a spring
clip.

I don't see that the drain line is held against the back of the machine by a
spring clip - the hose comes out of the machine, and the U-shaped end goes
to the drain, but there is nothing in between. The drain line looks
securely connected at the bottom.

Yes, I am going to get this repaired under warranty (albeit in 5 days), but
I was just wondering what common problems could be a possible cause of
having water in the tray under the washer, and inside the machine under the
tub.
