Model #WFR2460UC/01, this small front load washer started leaking whenever the customer started a wash cycle. The washer was installed under a counter top along with the dryer making it difficult to determine where the water was coming from, and after checking the hoses to ensure they were not the problem, the customer was out of ideas. With each wash, the amount of water seemed to increase and with a large family, and such a small washer by comparison, this was turning into a real problem.
Leaking washers, especially front loaders, are usually easily diagnosed by simply locating the source of the water leak. Sounds easy enough, but all to often, leaks seem to come and go depending for no apparent reason. The one thing to remember about any type of water leak is the leak will always be visible. Of course you need to find it first and since most the things that can leak are located inside the cabinet, some dis assembly is needed, but once inside, if water is leaking from any of the washer parts, you will be able to see it.
The seemingly intermittent leaks are the ones that poss the greater challenge in locating, simply due to their inconsistent nature. But if water has been flowing, it often times leaves a visible detergent trail that can be found when the water evaporates, and if your washer is anything but new, any dust inside will most certainly be displaced by the flow of water. So the moral of this story is, if you have an intermittent leak, don't look for the water, but instead, look for where the water has been. The trails become quite noticeable with time.
This washer wasn't experiencing an intermittent leak, but instead, the floor was definitely getting wet when it was being used. Using my keen powers of observation, I removed the rear panel from the washer and found the bottom of the cabinet holding a pool of water. With no noticeable signs of water dripping from above, I began looking around the drain and sump area for any signs of them being the source. Nothing was noticeable, so I started a wash cycle to add some water to the mix and presto, the leak showed itself.
The sumps in most front load washers are simply rubber hose connections between the bottom of the tub and the drain pump. They are meant to be flexible and are usually fairly large to allow for the movement of the tub during use. The potential for damage of these sumps is very low, with the exception of something poking through from the inside, or something chewing through from the outside. I didn't find any evidence of a mouse being the cause, so it appeared something had found it's way out of a pocket and into the drain section of this washer which most likely caused the damage.
I removed the sump and quickly found the source of the water and what looked to be a puncture hole. A further inspection of the drain pump didn't locate the item that caused the leak so it most likely has already made it's way out the drain. I installed a new sump between the tub and drain pump, and after securing the clamps applied power again and started a wash cycle. This time, the tub filled, but there was no water leak to be found.
