My Bosch Dishwasher Is Leaking Between Washes

Spray Arm

• If your spray arm has a split in it, it could be spraying water toward the door and lining of the dishwasher, causing it to leak. Access your spray arm by removing the top rack of your dishwasher and turning it upside down. The spray arm is attached to the rack with a nut that you can remove by rotating it counter-clockwise. A bottom spray arm is under the bottom dish rack. Check for any splits in the spray arm. If the spray arm is split, you will need a replacement part. If it is not split, check for any obstructions that could be becoming dislodged during the cycle, causing the leak. Flush the spray arms under water and reinstall them.

Condensation Vent

• The condensation vent could be blocked and impairing the dishwasher's ability to drain correctly. When you load the dishwasher, ensure that you are not blocking the condensation vent. This vent is typically on the right side of a Bosch dishwasher. Place tall items on the left side of the dish rack.

Installation

• There may be an installation problem that is causing the dishwasher to leak between cycles. Check if your dishwasher is level. If it is not, remove it from the cabinet and re-install it according to your Bosch dishwasher manual. The door may also need to be realigned if it does not fit properly between the cabinets. Also check that the door is properly sealed.

Hoses

• Hoses that have holes or kinks could cause your dishwasher to leak between cycles. Check the hose that goes to your upper spray arm, your dishwasher's drain hose and any other hoses heading to your kitchen sink or garbage disposal.

Other Problems

• If your dishwasher has suds in it after the rinsing cycle, you may be using the wrong soap or the wrong amount of soap. Eliminate the suds by adding one tablespoon of vegetable oil to the dishwasher's bottom tub during a cycle. Don't combine a rinse aid with water that has already been softened or this could result in additional suds. Problems with your door or corner gaskets also could be causing the leaks.
