Bosch E24 Error Code

E24 on a Bosch dishwasher is a drainage fault: the machine can't pump the dirty water out. It's almost always a clogged filter or a kinked/blocked drain hose — rarely the pump itself.

E24

Means: Drainage error — the dishwasher couldn't empty the water within the expected time, usually because the path out is blocked.

Fix: Clean the filter at the bottom of the tub and check the drain hose for kinks or clogs. Also confirm the sink's waste connection isn't blocked. Run a cycle to confirm.

What causes a Bosch E24 error

E24 appears when water is still present after the drain phase. Causes, most likely first:

  • Clogged tub filter: food debris and grease block the filter basket at the bottom. The #1 cause.
  • Kinked or blocked drain hose: a hose bent behind the machine or clogged with sludge.
  • Blocked sink waste / air gap: if the dishwasher drains into the sink trap, a clog there backs water up.
  • Clogged or faulty drain pump: a stuck impeller (glass, a seed) or a worn pump if everything else is clear.

Step-by-step fix

  1. Turn off the dishwasher. Remove the bottom rack and lift out the filter assembly at the base of the tub.
  2. Rinse the filter under a tap, clearing food and grease. Wipe out the sump beneath it and check for objects near the pump.
  3. Pull the machine out and straighten the drain hose; flush it if it's slow or sludgy.
  4. Check the sink waste connection and air gap for clogs, especially if you recently ran the garbage disposal.
  5. Refit the filter, restore power, and run a rinse cycle to confirm E24 is cleared.

When to call a technician

If the filter, hose and sink drain are all clear and E24 persists, the drain pump may be jammed or failed. Clearing the impeller is a moderate DIY job; a dead pump means a replacement part or a service call.

FAQ

Where is the filter on a Bosch dishwasher?

At the bottom centre of the tub, under the lower spray arm. Twist the cylindrical filter anticlockwise to remove it, then lift out the flat mesh screen beneath.

Can a blocked sink cause the E24 code?

Yes. Many Bosch dishwashers drain into the sink trap or an air gap. If that's clogged — often after using the garbage disposal — water backs up and triggers E24.

How do I reset a Bosch E24 error?

Once you've cleared the blockage, run a fresh cycle. If the water now drains, the code clears itself. You can also hold the Start button for a few seconds to cancel and reset the current cycle.
