Step-by-step
1
Clean internal filters
This is the most likely cause of this error.
2
Check drainage hose is not kinked, squashed or blocked
Even minor blockages can trigger errors.
3
Run quick cycle and listen for water movement
4
If the pump hums with no water movement it may be a blocked impeller
See details below
Diagnostic
Symptoms to look for
- Water is sitting in the bottom of the dishwasher after the cycle ends
- The machine stops partway through a cycle
- A humming or buzzing noise from the pump area with no water movement
- Error code appears at the end of a cycle
- Dishes remain wet and dirty after what should have been a completed wash
Step-by-step repair guide
How to fix it
Remove and clean the filters
a blocked filter is the most common cause of E24
Running a regular cleaning cycle with a Dishwasher cleaner can help dissolve grease build up in the filters and pipes
Check the drain hose at the back of the machine
It should loop up high before connecting to the waste pipe — this prevents back-siphoning. Ensure it is not kinked or squashed. Even the slightest bend or kink can cause the error.
Check the drain hose for blockages
Disconnect the drain hose from the sink waste/standpipe and check for blockages inside the hose itself.
Check the connection point on your kitchen sink
If it has a blanking plug that was never removed, the water has nowhere to go. This could be the case if the machine has just been installed.
Run a test cycle
Run a ‘Rinse’ or ‘Quick’ programme and listen to the drain pump. A constant hum with no water movement suggests the impeller is jammed — remove the filter and try to clear any debris from the pump housing.
Use cut resistant gloves or tweezers to check and remove debris from the pump impeller. Broken glass is a common cause and poses a cut risk.
Escalation
When to call an engineer
- The E24 error keeps returning after cleaning the filter and drain hose
- The dishwasher won’t drain at all, even after clearing visible blockages
- The drain pump is silent or not running during the drain cycle
- You hear unusual noises (humming, grinding) from the pump area
- The drain hose and plumbing are clear, but the issue persists
- There may be a faulty drain pump or internal blockage you can’t access
- You’re unable to safely remove panels or inspect internal components
Common questions
Frequently asked questions
Is the Siemens E24 the same fault as E25?
No. E24 is a general drainage timeout. E25 specifically means the drain pump impeller is blocked or jammed. Both result in drainage failure but have slightly different causes.
I replaced the Siemens drain pump but still get E24 — what else could it be?
Check the drain hose path carefully. A kink in the hose or a partial blockage in the connection to the sink standpipe can prevent even a new pump from draining the machine.
Can I use a Bosch drain pump in my Siemens dishwasher?
In many cases, yes — they share the same BSH components. Always match the part number from your machine’s model plate to ensure compatibility.
This video shows you what checks to carry out when the E24 error is displayed. - Siemens and Neff share a platform so the checks and solutions are the same.
