Causes of a faulty lower door seal include dry rotted or cracked rubber compromising the seal over many years of use. Food debris or mineral buildup along the seal interface can also inhibit proper closure. Symptoms of a bad lower door seal include: Puddling, leaks, or excessive moisture inside the dishwasher Poor drying results from inadequate containment of wash chamber humidity Errors related to blocked moisture sensors detecting intrusion Inability to close or latch the dishwasher door completely This lower door seal replacement is also compatible with some Thermador, Gaggenau, and Kenmore dishwashers using the same door seal profile.Part Number 00298534 (AP2802338) replaces 1021754, 298534, PS8703115.
