Bosch Dishwasher Error Code E24
Water is left in the bottom of the machine because the drain path is restricted, and Bosch points first at a blocked drain filter. Kinks in the drain hose and a loose pump cover cause the same symptom. This is the classic DIY Bosch code: clean the filter, check the hose, and it usually clears.
Also shown as: E6103
Common causes
- Blocked drain filter
- Kinked or blocked drain hose
- Loose drain pump cover
- Knock-out plug left in a new garbage disposal connection
What to check, in order
- Remove the filter and wash it under running water until the mesh is clear.
- Take out the pump cover under the filter, clear any debris and refit it firmly.
- Check the drain hose behind the machine for kinks or crushing.
- If connected to a garbage disposal, confirm the knock-out plug in its inlet was removed.
- Run a short cycle and check that the base empties fully.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
- Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
- If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E24, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
