How to Reset the Bosch Dishwasher E24 Error Code?

You load the dishes, press start, walk away. Twenty minutes later the machine has stopped and E24 is blinking at you. Annoying, yes, but here’s the good news: most people fix this one themselves in under an hour, no tools required. At Dishwasher Repair here in Toronto, E24 is one of the calls we get most, and honestly, half the time the caller could have sorted it out with a rinse under the tap. So before you book anything, try the steps below.

What Does Bosch Dishwasher Error Code E24 Mean?

E24 means your Bosch dishwasher can’t drain. Water went in fine, but it’s not going out, and the control board notices when the tub doesn’t empty in time. Nine times out of ten the culprit is boring: a filter packed with food scraps, a hose that got pinched when someone shoved the machine back, or a clogged connection under the sink. Occasionally it’s the drain pump itself. Its cousin, E25, points more squarely at the pump. Either way, start with the easy stuff.

Check These Parts First

You don’t need a screwdriver for any of this.

Clean the Dishwasher Filter

Slide out the bottom rack and twist the round filter out of the tub floor. Take a look. Rice, seeds, that one blueberry from last Tuesday? That’s your problem. Rinse it under warm water, scrub it with an old toothbrush, and lock it back in. And do lock it properly, because a loose filter can set off drainage errors on its own. Of all the dishwasher repair jobs out there, this is the easiest one you’ll ever do.

Inspect the Drain Hose

Follow the drain hose from the back of the machine to your sink or standpipe. Kinks are common, especially if the dishwasher was pushed back hard against the wall. Straighten anything bent. If you can, disconnect the hose and run water through it. Gunk loves to settle in the ridged sections.

Check the Drain Connection

Hose looks fine? Check where it ends. A clogged sink drain or garbage disposal will back water up into the machine. If your Bosch dishwasher was installed recently and hooked to a disposal, make sure the little knockout plug inside the disposal inlet was actually removed. Installers forget. It happens more than you’d think.

How to Reset the Bosch Dishwasher E24 Error Code

Cleared the drainage path? Now reset the machine.

Restart the Dishwasher

Hold the Start button for about 3 to 5 seconds to cancel the cycle, then give the pump a minute to push out any standing water. After that, cut power completely. Flip the breaker or pull the plug and wait five minutes. This wipes the stored fault from the board.

Verify the Error Has Cleared

Power back on and run a quick cycle. Stand there for the first minute and listen. You should hear the drain pump hum and see water leave the tub. If E24 comes back, the problem sits deeper inside, and that’s where dishwasher repair gets a bit more involved.

Advanced Fixes for Bosch Dishwasher Error E24

Under the filter housing there’s a small pump cover you can pop open with a spoon handle. Check the impeller for glass shards, olive pits, or bits of bone. It should spin freely with a fingertip.

Repair or Replace the Drain Pump

Impeller spins but the pump stays silent during draining? The motor has likely died. Swapping the pump on a Bosch dishwasher means pulling the base panel, so plenty of owners hand this off to a dishwasher repair pro.

Inspect the Circulation Pump

A weak circulation pump can leave water sitting in the tub and fake a drainage fault. Grinding or odd humming mid-wash is the giveaway.

Repair or Replace the Control Module

If every part checks out and the code won’t quit, the module may be misreading its sensors. That’s proper Bosch dishwasher repair territory, not a weekend project.

Final Thoughts

The Bosch dishwasher E24 error code is nearly always a blockage somewhere between the filter and the drain. Clean the path, reset, and run a test cycle. Still stuck? Professional Bosch dishwasher repair will sort it without the guesswork, and your Bosch dishwasher will be back to earning its keep by dinner.
