Bosch dishwashers are well-known for their quality, efficiency, and advanced features. However, like any high-tech appliance, they can run into issues from time to time. One of the most common error codes Bosch dishwasher owners encounter is E15. But what does this code mean, and how can you fix it? At Express Repair, we specialize in appliance repair solutions that get your household back on track. Here’s everything you need to know.
The E15 error code on a Bosch dishwasher typically indicates that water has leaked into the base of the appliance, triggering the anti-flood protection system. This safety feature is designed to prevent water damage by stopping the dishwasher and activating the drain pump.
When E15 appears, the machine often won’t start or may make a humming sound as it tries to drain water from the base.
Several factors can lead to the E15 error code:
Leaky or damaged hoses
Over time, hoses can develop small cracks or loose connections.
Faulty or worn-out seals
Door gaskets or pump seals may deteriorate and allow water to seep into the base.
Overfilling or user error
Using too much detergent or loading dishes improperly can cause water to overflow internally.
Clogged filters or blocked drainage
When water can’t drain properly, it may accumulate and leak into the bottom of the unit.
While we recommend professional diagnosis and repair, here are a few steps you can try at home:
Unplug the unit and gently tilt it backward at a 45-degree angle. If there’s water in the base, this may help it drain out and reset the sensor. Be cautious—have towels or a bucket nearby.
Inspect hoses, seals, and the bottom tray for signs of water leakage. Dry everything thoroughly before powering the unit back on.
Remove and clean the filters to ensure proper drainage. Blocked filters can cause internal overflow.
After drying and inspecting, plug the appliance back in and try running a short cycle. If the error persists, the leak may still be active or the float switch might be stuck.
