The location of the drip seems to be 1/2" to the right of where the latch for the detergent cups is located. My theory is that the small square gasket around the latch is letting water get inside the door, and that is why it is taking a while for the water to soak up the insulation on the inside of the door, and then make its' way to the bottom of the door and then leaking out the bottom of the door. The rinse aid cap is also near this location, but I suspect the gasket more than the rinse aid cap, based on my own opinion from examining these two items. Do you think I'm correct in diagnosing the detergent cup door latch gasket as the cause of the leak, or could it be something else like the black rubber gasket around the door, or the rinse aid cap?
Assuming that the gasket around the latch for the detergent caps is indeed the cause, then the next question is can I replace this small gasket myself, or do I need to have a professional do this? I notice that they sell a latch/gasket kit online for only $2.50. Does replacing this gasket involve removing the white plastic panel on the INSIDE of the door? This panel appears to have special bolts which seem to require a special "star shaped six point wrench" rather than a standard Allen hex wrench. If getting to the gasket involves removing the white plastic panel on the INSIDE of the door, then where can I buy this special wrench, and would it be easy for me to do this job myself? Is there another way to replace this gasket, such as, by removing the OUTSIDE panel of the door, and if so, then how do I do that?
Any potential snags I need to know about...such as would I need a special glue or tools to install the new gasket, etc, or is it likely I could cause other leaks by doing this repair myself?
This may be grasping at straws, but is there some type of caulk I could use, or anything else I could use, that could potentially fix the problem WITHOUT having to take the door apart?
If you think this fix is NOT a do-it-yourself job, then do you think it would be worth spending $100 or more for a repair, or should I simply use the money toward a new dishwasher? What is the typical life of this dishwasher, and how much does an equivalent model cost these days?
Thanks for your advice.
