Bosch Dishwasher Error Codes — Complete Error Code Diagnosis Guide

This is the largest error-code index on the site: 23 Bosch dishwasher guides, spanning the E-series the machine shows on its display and the F-series that turns up on Gaggenau and Thermador siblings built on the same platform. Water supply and drainage account for E16, E18, E22 and E24. Heat runs through E04, E08 and E09. E15 and F1 are leak protection — water in the base pan lifting the float. E01 is the heat-pump motor, E07 the CrystalDry fan, E12 limescale in the heat pump, and E14 a flow meter whose turbine has scaled or jammed.

A list this long is only useful if it narrows quickly, so the guides are built to be entered from the code and left with one component. Codes that share a symptom are cross-checked against each other: E16 and E18 both leave the machine short of water, but one points at the valve and float and the other at a supply that was turned off or a hose that is kinked. E12 and E14 are both hard-water stories, which is why descaling appears as a repair and not only as maintenance. Filter and hose checks come before any pump is condemned.

Leak-protection codes are the ones to act on immediately. Bosch machines trip the base float when water reaches the pan, and continuing to run cycles keeps feeding a leak that has already been detected. The AquaStop hose carries a valve at the tap end and is not a generic replacement. Line voltage reaches the heat pump and the control in a cabinet that is wet by design, so the supply goes off before a sump seal or door gasket is disturbed.
