Do you have the o-ring in stock?
Answer Hello Lori. The manufacturer does not offer the o-ring separately from the assembly W10187809.
The installer needs a 10' feed hose and a shut off valve for this model dishwasher. Do you have them?
Answer Toni, 10' inlet hose is part number 8212486 and 10' drain hose is part number GPF10L. We do not have a shut off valve available, this can be purchased at a home hardware store. Thanks.
