Bosch Dishwasher Error Code E:15

E:15 means the float switch in the base pan of your Bosch dishwasher has been activated by the presence of water. The appliance responds by running the drain pump continuously as a safety measure. The dishwasher will not complete a normal wash cycle until the water in the base is removed and the float switch returns to its resting position. The root cause is typically a water leak from an internal component or a blocked drain that caused overflow into the pan.

You should not continue using the dishwasher while E:15 is active. Water in the base pan near electrical components creates a risk of short circuits or further damage to the control board and motor. The dishwasher's continuous drain pump operation is a safety response, not normal operation. Resolve the source of the water before running another cycle.

Repair costs vary widely depending on the cause. If the fix only requires clearing a clogged drain or freeing a stuck float, there may be no parts cost at all. Replacing a door gasket typically runs in the range of $20 to $60 for the part. More involved repairs such as a failed inlet valve or pump seal can range from $80 to $250 or more when including parts and labor. A professional diagnostic visit alone commonly costs between $75 and $150.

Start by tilting the dishwasher slightly to allow any water in the base pan to drain out, then check that the float switch moves freely and is not stuck. Next, inspect and clear any debris from the drain pump and drain hose. If water continues to reappear in the base pan after running the unit, you will need to identify the internal source of the leak, which could be the door gasket, a hose connection, the inlet valve, or a pump seal.

A reset may temporarily clear the E:15 code from the display, but the error will return if water is still present in the base pan or if the float switch remains stuck in the raised position. Resetting does not address the underlying cause. You need to physically remove the water from the base and fix the source of the leak before the error will stay cleared.
