Common Bosch codes and cautious interpretations
Record the exact characters, including whether the display shows E15, E24, E25, E09, or another code. Some models show a faucet or tap indicator instead of, or alongside, an alphanumeric message. The manual for your model is the best first reference.
| Display | Common meaning and safe response |
|---|---|
| E15 | Often indicates that the base water-protection system has detected water. Stop cycles, prevent water spread, and arrange leak diagnosis; do not tip the dishwasher. |
| E24 or E25 | Often relates to draining or a drain-pump restriction. Check only the filter and drain items your manual identifies as user-serviceable. |
| E09 | Often relates to the heating system on many models. Do not run repeated cycles or replace heating parts without diagnosis. |
| Tap indicator or another code | May relate to water supply or a different model-specific function. Use the exact manual rather than substituting a generic E-code meaning. |
For E15, prioritize leak control over resetting
If water is visible, stop using the dishwasher and keep people away from wet electrical areas. Shut off the water supply only if the valve is safely accessible and you know which one serves the dishwasher. Do not stand in water while reaching for a plug or breaker.
Do not tilt the appliance to drain the base. Tipping can move water into other components, damage flooring or connections, and hide the original leak path. A technician should determine where the water came from and whether related parts were affected.
For E24 or E25, keep drain checks model-specific
Cancel the cycle using the normal controls and check for standing water. If your manual permits routine filter removal, inspect it with the appliance off and cool, following the release and cleaning directions exactly. Reinstall every part securely before use.
Check the visible drain connection only if it is safely accessible under the sink without dismantling plumbing. Do not use chemical drain cleaner, force objects into the pump, or reach past a filter into an impeller area. Persistent drain codes can involve the pump, hose, household drain, sensors, wiring, or controls.
For E09 and heating symptoms, avoid repeated test cycles
Poor drying or water that does not warm can accompany a heating-related code, but symptoms alone do not identify the failed component. Heating, sensing, wiring, and control issues may require model-specific electrical testing.
Do not open the door mid-cycle to check for hot water or steam. Arrange service rather than bypassing a safety device or replacing a heater based only on an online code chart.
What to share when booking Bosch dishwasher service
Provide the full model number, code photo, whether water remains in the tub, any visible leak location, and what happened before the code appeared. Mention if the household drain or garbage disposal was recently changed, but do not disconnect plumbing yourself.
