Bosch Dishwasher E15 Error: Your First Five Minutes

You open the kitchen and the dishwasher is silent, the cycle is dead, and the display reads E15. That code comes from the AquaStop system: a float switch in the base pan sensed water and closed the inlet so nothing could overflow. The machine is protecting your floor, so give it a calm, orderly response.

Do these first

1. Close the supply valve, usually under the sink or behind the kickplate.
2. Look at the floor around the unit and inside the cabinet next to it for puddles or damp wood.
3. If the area is clear, ease the dishwasher forward a few inches and check beneath the front edge.

Keep the movement gentle. Tipping the machine can slosh water around inside the base, and the pan itself is not something to open at home.

What to leave alone

Resist the urge to press Start again just to see whether the message disappears. If a hose, seal, or pump really is dripping, another run will push more water onto the floor and into the cabinetry. A cleared screen proves nothing about the cause.

Real leak or false alarm?

The float can stick, and moisture inside the pan can sometimes trip it, so E15 does not always mean a puddle exists. Telling a genuine leak from a false trigger means looking at the hoses, door seal, and pump with the base accessible. That is work for a technician rather than a guess.

Next step

Having a towel and a flashlight nearby makes the floor check quicker, and a photo of the display helps when you talk with us.
