Bosch E24 Error: Drain Problem Solved Step by Step

Quick Answer

Bosch E24 means water is not draining. Clean the triple filter first - this fixes E24 in about half of all cases in under 5 minutes. If the filter is clean, check the drain hose for kinks and confirm the high loop is correct. New install? Check if the garbage disposal knockout plug was removed. E24 is a path problem; if the pump impeller itself is jammed it becomes E25.

Bosch E24 means the dishwasher cannot drain properly. The most common cause is a clogged triple filter system at the bottom of the tub - cleaning it takes under 5 minutes and fixes E24 in about half of all cases. Other causes include a kinked drain hose, a blocked pump impeller (which becomes E25), a clogged air gap, or a garbage disposal knockout plug that was never removed on new installs. E24 is a path problem; E25 is a pump problem.

What Does the E24 Code Mean?

Bosch uses a three-part filter system: a coarse mesh filter, a fine mesh microfilter, and a cylindrical mesh filter that screws into the sump. When these are clogged with food debris, water cannot reach the drain pump fast enough, and E24 triggers. The filter should be cleaned monthly in households that run the dishwasher daily. Beyond the filter, E24 can be caused by anything that restricts the drain path from the dishwasher to the drain line.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Clogged triple filter system (most common)40%
Kinked or improperly installed drain hose24%
Garbage disposal knockout plug not removed (new installations)14%
Drain pump impeller blocked by debris (transitions to E25)12%
Blocked air gap on the sink counter10%

Symptoms You May Notice

  • E24 displayed, cycle stops during drain phase
  • Standing water visible at bottom of tub after cycle
  • Drain pump audible but water not moving
  • Water drains slowly over several hours after cycle ends

Can you reset a Bosch dishwasher to clear the E24 code?

After clearing the drain path, hold Start/Reset for 3-5 seconds. The pump will run briefly to clear remaining water, then stop. Restart a short rinse cycle to confirm the drain is working.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Clean the triple filter system

Reach into the bottom of the tub and turn the cylindrical filter counterclockwise to remove it. Lift out the flat mesh filter beneath it. Rinse both under hot water, scrubbing with a soft brush. Reinstall the flat mesh first, then the cylindrical filter (turn clockwise until it clicks). Run a short rinse cycle and check if E24 returns.

2

Inspect the drain hose for kinks

3

Check the garbage disposal knockout plug

4

Check the air gap if installed

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Is E24 the same as E25?
No. E24 means the drain path is blocked - the water has somewhere to go but cannot get there because something is in the way (clogged filter, kinked hose, blocked air gap). E25 means the drain pump impeller itself is blocked or jammed, so the pump cannot move water even if the path is clear. Fix E24 first; if the code changes to E25 after clearing the filter and hose, you have a pump impeller issue.
Can a clogged filter cause E24?
Yes, and it is the most common cause. Bosch's triple filter system catches food debris to keep it out of the pump, but once the filter is saturated with residue, water flow drops below what the pump needs. The control board detects the drain cycle failure and throws E24. Monthly filter cleaning prevents this entirely.
E24 keeps coming back after cleaning. Why?
If E24 returns within a few cycles of filter cleaning, the problem is likely further along the drain path: a kinked hose, a blocked air gap, or a partial clog in the drain pump impeller. Systematically check each point in the drain path. A partially blocked impeller can pass a filter-cleaning test but fail under a full load.
Does the garbage disposal affect my Bosch?
Yes, in two ways. First, if the disposal is new and the knockout plug was not removed, the dishwasher has no path to drain at all. Second, if the disposal is running while the dishwasher is draining, it can create backpressure that slows or reverses the drain flow. Always run the disposal before starting the dishwasher, not simultaneously.
