Bosch Washing Machine E24 Error Meaning and Drain Fault Checks

User question

What does E24 error mean on Bosch washing machine?

Artificial Intelligence Response

Direct answer to the question

On a Bosch washing machine, an E24 error is not a common standard laundry-washer code across all Bosch models. In many cases, people see E24 on a Bosch dishwasher, where it means a drainage fault: the machine cannot drain water properly.

If it is truly a Bosch laundry washing machine, E24/F24 is usually model-specific and may indicate a water-level, overflow, AquaStop/leak protection, or drain-related fault. The exact meaning depends on the model number.

Detailed problem analysis

If your appliance is actually a Bosch dishwasher

For Bosch dishwashers, E24 almost always means drain problem.

Common causes:

• Blocked filter or sump.
• Food debris, glass, or other obstruction in the drain pump impeller.
• Drain pump cover not fitted correctly.
• Kinked or blocked drain hose.
• Blocked sink drain, air gap, or garbage-disposal connection.
• Faulty drain pump, less commonly.
• Control board or sensing fault, rarely.

What to check:

1. Turn the appliance off and disconnect power.
2. Remove and clean the filter.
3. Check the sump area for debris.
4. Make sure the drain pump cover is clipped in properly.
5. Check that the drain hose is not kinked or blocked.
6. Check the connection under the sink or to the waste pipe.
7. If everything is clear and E24 remains, the drain pump may need testing or replacement.

If it is definitely a Bosch washing machine

Bosch laundry washers more commonly use codes such as E18/F18 for drainage problems and F23/E23 for AquaStop or leakage protection, depending on the series. Therefore, E24 on a washing machine should be treated as model-specific.

Possible causes include:

• Water not draining correctly.
• Blocked pump filter.
• Jammed drain pump impeller.
• Faulty water-level pressure sensor.
• Blocked pressure hose or pressure chamber.
• Overflow condition.
• Water in the base tray triggering leak protection.
• Control module fault.

Basic checks:

1. Unplug the machine.
2. Open the lower front service flap.
3. Drain water using the emergency drain hose, if fitted.
4. Unscrew and clean the pump filter.
5. Check for coins, lint, hairpins, or fabric debris.
6. Verify that the pump impeller can rotate freely.
7. Check the drain hose for kinks or blockage.
8. If the pump runs continuously or the machine appears to think it is flooded, check for water in the base tray or a leak.

Practical guidelines

Before replacing parts, do this sequence:

Step	Check	Likely result
1	Confirm appliance type	Dishwasher E24 is much more common
2	Find exact model number	Needed for correct Bosch washer code meaning
3	Clean filter/pump area	Most common fix
4	Check drain hose and plumbing	Prevents false drain faults
5	Inspect for leaks or overflow	Relevant if AquaStop is triggered
6	Test drain pump and pressure sensor	If mechanical blockage is ruled out

The model number is usually on the door frame or rating plate and may look like WAN…, WAT…, WAE…, WAW…, WGG…, SHX…, SMS…, SMV… etc.

Brief summary

• Bosch dishwasher E24 = drainage fault.
• Bosch washing machine E24 = unusual/model-specific; often related to drainage, water-level sensing, overflow, or AquaStop/leak detection.
• First clean the pump/filter area and check the drain hose.
• If you give me the exact Bosch model number, I can identify the specific meaning of E24 for your machine.
