Pick the code your Bosch appliance is showing. Each page explains what the code means, the most likely causes ranked by probability, and which fixes are safe to try before calling a technician.

Bosch Dishwasher Codes

• E15 Water reached the base pan under the tub and Bosch's leak protection locked the machine — sometimes a genuine leak, often a one-off spill or condensation that clears once the base dries.
• E24 The dishwasher can't drain properly — start with the filter, then the drain hose path, and don't skip checking that the drain pump cover is seated.
• E25 The drain pump itself is blocked or its cover is loose — and Bosch makes the pump cover owner-accessible, so this is one of the most fixable codes the brand throws.
• E09 The heating system isn't raising the water temperature — beyond one reset, the flow-through heater is a mains-voltage part that belongs to a technician.
• E14 The flow meter that counts water into the machine stopped making sense, so filling can't be trusted — a reset and supply check first, then it's a sensor-level repair.
• E17 Water is rushing in faster than the fill system expects — household pressure at the high end or an inlet valve not throttling properly are the leading explanations.
