Bosch E15 Error Code

E15 on a Bosch dishwasher means the anti-flood float has tripped: water has collected in the base pan. It's usually a small leak or condensation pooling, and it often clears once the base is dried out.

E15

Means: Anti-flood (AquaStop) triggered — the safety float in the base pan detected water and shut the machine down to prevent a flood.

Fix: Tilt the dishwasher back to drain water from the base, or soak it out with a cloth, so the float drops. Then run a cycle to confirm E15 has cleared.

What causes a Bosch E15 error

E15 fires when a polystyrene float in the base pan rises on collected water and trips a micro-switch. Causes, most likely first:

  • Water pooled in the base pan: from a minor leak, over-sudsing, or condensation. The float just needs to be lowered. #1 cause.
  • Leaking door seal or spray arm connection: small drips slowly fill the base.
  • Loose or cracked hose clamp: a weeping connection inside the machine.
  • Faulty float switch: less common, but possible if the base is dry and E15 persists.

Step-by-step fix

  1. Turn off and unplug the dishwasher, and shut off its water supply.
  2. Pull the machine out and carefully tilt it backward about 45 degrees for 30 seconds to let water drain from the base out the rear.
  3. Alternatively, remove the bottom kick plate and soak the water out of the base pan with a sponge or cloth until the float drops.
  4. Check the door seal and visible hose clamps for drips while you're in there.
  5. Stand the machine back up, restore power and water, and run a short cycle to confirm E15 is gone.

When to call a technician

If E15 returns quickly, there's an active leak that needs tracing — often the door gasket, a hose, or the pump seal. If you can't find the source, or the float switch tests faulty, book a service call.

FAQ

How do I drain the water causing a Bosch E15?

Unplug the machine, tilt it back about 45 degrees for 30 seconds to let base water run out the rear, or remove the kick plate and soak it out with a cloth so the float drops.

Can too much detergent cause E15?

Yes. Over-sudsing or using non-dishwasher soap can push foam and water into the base pan, tripping the anti-flood float. Use only dishwasher detergent in the correct dose.

Will E15 clear by itself?

Once the base pan is dry and the float has dropped, the code clears on the next cycle. If water keeps returning, you have an active leak that needs fixing first.
