Leaking dishwasher

There are a number of reasons why the dishwasher may be leaking. It is important to inspect the appliance carefully in order to locate where the problem is coming from.

Open Bosch dishwasher

Damaged door seal

If you see water leaking from the door, open it wide and inspect the door seal for any visible damage. If you see tears or pieces of the door seal missing, order a replacement part. You can purchase a replacement door seal using our spare parts search and entering the appliance information to get the bill of materials or by calling customer service on 0344 892 8979, where a member of our customer service team will assist your further with your query.

You can replace the door seal by following the advice given on this page.

Damaged spray arm or loose water outlet connection

If the spray arm is damaged, it can force water to spray directly toward the dishwasher door seal, causing a leak. First, check if your spray arm can rotate properly. To do this, open the appliance door and remove the dishwasher rack as shown in the instruction manual. If the spray arm rotates fully, follow the instructions in your manual to remove the spray arm, and check if the tube connection on the pump’s water outlet opening, located behind the spray arm insert is tightened. Ensure that the connection is tightened then replace the spray arm into position.
