Bosch is a German engineering conglomerate whose home appliance division (BSH Hausgeräte) produces products under the Bosch, Siemens, Neff, and Gaggenau brands. Bosch appliances are positioned as premium products emphasizing quiet operation, energy efficiency, and compact European design. Their dishwashers are consistently rated among the quietest available (as low as 38 dB), while their compact 24-inch washers and heat pump dryers are specifically designed for space-constrained installations common in urban apartments.
Bosch appliances display error codes using the letter E followed by a number: E15, E22, E24, E25 on dishwashers; E02, E13, E17, E18 on washers; and alphanumeric combinations on ovens and refrigerators. The E-code system is shared across all BSH brands (Bosch, Siemens, Neff, Gaggenau), so if you own a Siemens dishwasher displaying E25, the same Bosch E25 guide applies — the internal components are identical.
Bosch codes are notable for their specificity. While some brands use generic codes that could indicate multiple issues, Bosch codes typically point to one specific component or condition. E15 on a Bosch dishwasher always means water detected in the base pan (leak protection activated) — not a vague "water error." This precision makes diagnosis straightforward once you know what each code means.
Bosch appliances use premium components — stainless steel tubs, brushless motors, precision-machined pump assemblies — that generally last longer than economy brands. However, when these components do fail, replacement parts are often more expensive and may have longer shipping times due to European manufacturing. A Bosch dishwasher circulation pump may cost 2-3 times more than an equivalent domestic brand part. Our guides always note the price differential and suggest compatible aftermarket alternatives where quality-tested options exist.
Bosch compact appliances also present unique repair challenges due to their space-efficient design. Components are packed more tightly than in full-size American appliances, and disassembly sequences may require removing multiple panels to access a single part. Our guides include specific disassembly instructions tailored to Bosch's compact form factors.
Select your Bosch appliance type below. All guides apply equally to equivalent Siemens and Neff models with the same error code.
Bosch dishwasher E24 error means drain hose blockage is preventing water evacuation. Top cause: kinked or blocked drain hose (35% of cases). Full step-by-step repair with part numbers and prevention tips.
Bosch dishwasher E15 error means water leaked into the base pan and triggered the AquaStop flood sensor. Most common cause: a worn door gasket (35% of cases). Complete fix guide with the tilt method and part numbers.
