Is It Definitely the Door Seal?
Water appearing under the front of the dishwasher usually points to the door seal, but excess foam from too much detergent can also force water out at the door. Try one wash with no detergent to rule this out.
Door Seal Replacement Cost
A dishwasher door seal (gasket) replacement typically costs £65–£110 including parts and labour. On integrated models, access may take longer and push the cost slightly higher.
Other Causes of Door Leaks
Door Not Closing Properly
A misaligned or faulty door latch allows water to escape even with an intact seal. The seal compresses correctly only when the door is fully latched.
Damaged Seal Channel
The channel the seal sits in can crack or distort. If the seal itself is intact but leaking, the channel may need inspection.
