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.
