Bosch Dishwasher Error Codes: Complete List + Fixes

Quick Answer

Bosch dishwashers display error codes when a component or system fails a check. The most common codes are E15 (flood protection), E24 (won't drain), E25 (drain pump blocked), E09 (heating failure), and E22 (turbidity sensor or dirty filter). Most can be resolved without a technician. This page covers every Bosch dishwasher error code with a direct link to each full repair guide. Bosch, Siemens, and Thermador dishwashers share most codes since all three are made by BSH Group.

About These Bosch Dishwasher Error Codes

Bosch uses a consistent error code system across its 100, 300, 500, and 800 series dishwashers. Codes appear on the digital display (or as LED blink patterns on models without a screen) and correspond to a specific system check failure. Some older Bosch models display error codes during a power-on blink sequence rather than showing them as text. This guide covers all codes including the numeric E-codes, H-codes, and alpha-numeric service codes like SA NL and 5UC.

How to Identify Your Error Code

Note the exact code displayed

Look at your Bosch display carefully. Write down the exact code including any numbers after the dash (E92-40 is different from E92). On older LED-only models, count the number of times the indicator light blinks - each blink pattern maps to a specific error.

Frequently Asked Questions

What is the most common Bosch dishwasher error code?

E15 (flood protection) and E24 (drain failure) are the two most common Bosch dishwasher error codes. E24 is usually caused by a clogged filter or kinked drain hose. E15 is caused by water leaking into the base pan, often from an aging door gasket.

Are Bosch dishwasher error codes the same as Siemens?

Yes. Bosch and Siemens dishwashers are both manufactured by BSH Group and share the same control board platform. Nearly all E-codes are identical between the two brands. Thermador dishwashers, also by BSH Group, share most codes as well.

How do I read Bosch error codes on older models without a display?

On LED-only Bosch models, errors are communicated through blink patterns on the indicator lights. After pressing Start/Reset, count the number of times the light blinks. For example, on some older models, 4 blinks indicates E15. Check your model's technical manual for the specific blink-to-code mapping.

Can I fix Bosch error codes myself?

Most Bosch error codes can be resolved by a capable DIY homeowner. E24 (clogged drain), E22 (dirty filter), E15 (base pan leak), and E25 (blocked pump impeller) are among the easiest. Codes like E92 (control board communication) and E01/E02 (motor electrical faults) typically require more experience or professional service.
