What Does Error Code E24 Mean on a Bosch Dishwasher?

Drain blocked — dishwasher not draining.

E24 fires when the control board detects that standing water is not clearing within the expected drain cycle time — the pump runs but the water level sensor still reads full. It points specifically to a physical restriction in the drain path (filter, hose, disposal port, or impeller) rather than an electrical pump fault. This distinguishes it from E25, which typically flags a pump or drain-cover issue, and E15, which signals water in the base pan.

Models affected: Most Bosch dishwashers that report numeric E-codes, including the SHEM63W55N, SHPM65Z55N, SHXM4AY55N, SHEM3AY55N, SHP878ZD5N, and SHX878ZD5N.
What owners report: Owners commonly report E24 appearing mid-cycle with a pool of water left in the tub, and clearing the coarse and mesh filters often resolves it right away. A frequent false trigger is a newly installed garbage disposal whose knockout plug was never removed, or a high-loop drain hose that got kinked when the unit was pushed back into place.

What Causes Error Code E24?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Clogged drain filter and mesh screen 55% of cases
  2. 2
    Kinked drain hose behind dishwasher 20% of cases
  3. 3

  4. 4
    Drain pump impeller blocked by glass or debris 10% of cases

How to Fix Bosch Dishwasher Error Code E24

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Clean the drain filter system

    Remove the bottom rack. Unscrew the coarse filter (twist counterclockwise), then lift out the flat fine mesh filter. Rinse both thoroughly under running water using a brush.

  2. 2

    Check the drain hose

    Pull the dishwasher out slightly and trace the drain hose. It should loop up to the underside of the counter and not be kinked.

  3. 3

    Check garbage disposal

    Run the disposal before starting the dishwasher. If newly installed, check that the knockout plug was removed.

  4. 4

    Check pump impeller

    If filter is clean and hose is clear, reach into the sump and feel around the pump opening for broken glass or hard debris blocking the impeller.

    ⚠️ Use gloves — broken glass may be present.

How to Reset Error Code E24

After clearing the blockage, press the On/Off button for 3 seconds to reset, then run a short program.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If the filter and hose are clear but the pump still doesn't drain (you can hear it trying), the pump motor has failed.

Frequently Asked Questions

Can I keep using my Bosch Dishwasher when error E24 appears? +
It is not advisable. The dishwasher may still power on, but running it while E24 is active can worsen the drainage fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes E24 on a Bosch Dishwasher? +
Across reported Bosch dishwasher repairs, the most frequent is clogged drain filter and mesh screen (55% of cases), kinked drain hose behind dishwasher (20%), then garbage disposal connection blocked or knockout not removed (15%). Check them in that order before replacing any parts.
E24 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E24 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the drain filter system, then check the drain hose — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Bosch Dishwasher error E24? +
A DIY repair typically runs $0–$60 in parts, versus $100–$230 for a professional service call, so handling it yourself saves around $100. Expect the work to take roughly 30–60 minutes.
Which Bosch Dishwasher models show error E24? +
E24 is documented on Most Bosch dishwashers that report numeric E-codes, including the SHEM63W55N, SHPM65Z55N, SHXM4AY55N, SHEM3AY55N, SHP878ZD5N, and SHX878ZD5N.. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
