Bosch / Thermador / Gaggenau dishwashers: E-codes, resets and the stored-fault test program

Current BSH dishwashers show E-codes on the display; Bosch's own pages tie E24 to a drain problem and E15 to water in the base (leak protection). A reset is a power cycle or holding Start for a few seconds, which cancels the program and pumps out. Older models have a test program entered by holding two program buttons while switching on; it shows stored faults as numbers that add together (1, 2, 4, 8, 16), so a 3 means faults 1 and 2.
