Gaggenau dishwashers ride the BSH platform, so they use the same E-code family as Bosch. The common problems are an E15 base-tray leak, an E24 drainage fault, and weak drying, each with a defined, well-supported repair.
Because Gaggenau dishwashers share the BSH platform, an E15 means the same thing it does on a Bosch: water has reached the base tray and tripped the anti-flood float. It is a symptom of a leak upstream, a spray-arm seal, a hose, or the sump gasket, that must be found and repaired rather than simply reset. This is the most common Gaggenau dishwasher call.
E24 is a drainage fault: water is not leaving the tub fast enough because the filter is clogged, the hose is blocked, or the drain pump is jammed. Clearing the full drain path resolves nearly all of these. Weak drying, given the condensation drying method, usually means low rinse aid or a failed heating element.
The advantage of the shared platform is efficiency: the diagnostics are familiar and the parts are well supported through the BSH network, even on Gaggenau's premium units. We read the code, confirm the cause against the machine, and repair with genuine OEM parts so the fault does not simply return.
