The 3 Bosch dishwasher codes verified so far, whether or not each has its own page. Manufacturers document codes across several places, so a code missing here is one we have not confirmed yet — not one that does not exist. None has a page yet: each still needs confirmation from a second, independent source, so these rows state the meaning and nothing more.

E24	F24	E24 means the dishwasher is not draining properly because the drain filter is blocked. Water left pooling at the bottom of the tub, a cycle that pauses part-way, and gurgling or humming noises are the symptoms Bosch lists alongside it.	Not draining	Medium	Free check
E25	—	E25 means the dishwasher's drain pump is either blocked or its access cover is loose or missing.	Not draining	Medium	Free check
E22	F22	E22 means the dishwasher's filter is blocked, typically by trapped food particles.	Not draining	Medium	Free check

Before you check anything

Disconnect the power first. Unplug the machine at the socket, or switch off its circuit at the consumer unit if it is hard-wired. Do this before opening any panel, reaching into a pump filter, or moving the appliance.
Turn off the water before disconnecting a hose, and have a towel and a shallow tray ready — a drain hose holds water even when the drum looks empty.
Gas, mains wiring and sealed refrigeration are for a qualified professional — in many countries that is a legal requirement, not advice. If you smell gas, do not touch any switch: leave, and call your gas emergency number from outside.
Stop if you smell burning, see scorched wiring, or find water near an electrical connection. None of those is a code to look up.

The checks on this page are the manufacturer’s own, rewritten and sourced, and they are reference information rather than a repair instruction for your particular machine. Model, age and installation all change what is safe to do. You are the one standing in front of it — if a step looks wrong for the machine you have, trust that and call a technician.
