Answer J, Yes, 99002003 would stop the leak from the reservoir, if thats where the leak is located, did you try tightenning the reservoir nut first. Have you dismantled the door and checked the upper portion of the insulation for moisture ? and did you check the exhaust vent on the door for a possible water leak or stem leak from the vent housing. You also want to check the door alignment and hinges, the dishwasher could be blowing water up into the opening between the door and tub, if the door is not aligned properly. Thanks

Answer Hello Todd. Check and make sure the vent inside the door has not come off. If not, then the seal 99002003 has stretched and will need to be replaced in the vent assembly. Hope this helps.
