Bosch Dishwasher · Code E15 / E3100

Bosch Dishwasher E15 code: Water in the base (leak protection)

A float switch in the pan under the dishwasher detected water, so the AquaStop leak protection shut off the water supply. It means water got where it shouldn't, from a leak or overflow inside the machine.

Most common causes

  1. Leaking door seal or gasket
  2. Leaking hose or inlet valve
  3. Too much suds from the wrong detergent
  4. Crack or damage to the tub or sump

What you can safely check yourself

  1. Turn off the water supply to the dishwasher and unplug it. Water sitting in the base pan has to be drained and the leak found, which is a job for a technician because the dishwasher has to be pulled out of the cabinet.
  2. Use only dishwasher detergent, never dish soap.
  3. Check the door seal for tears or debris.

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.

Use only dishwasher detergent, never dish soap. Check the door seal for tears or debris. Bosch says to call for service after shutting off the water.
