What E24 means

Open the door after a cycle and you find dirty water sitting in the bottom of the tub, with E24 lit up. The dishwasher ran its drain step, but the water level never dropped the way the control expects. Most of the time food debris is blocking the filter, though a bent drain hose or a weakening pump can leave the same standing water and the same code.

Common causes of E24

  • Clogged filter in the tub floor (by far the most common, and the easiest to check)
  • Drain hose kinked or packed with debris, often where it joins the disposer or sink line
  • Drain pump or drain valve weakening
✓ One safe check you can try

1. Switch the dishwasher off at the breaker. 2. Scoop out standing water with a cup and towel. 3. Twist out the filter assembly in the floor of the tub, which comes out by hand; stop if it resists. 4. Rinse the filter under the tap, scrubbing away food debris. 5. Refit it fully seated and run a short cycle. Do not reach into the pump housing below it.

! Why to stop there
  • Past the filter you meet the pump motor, which runs on live voltage.
  • A hose put back slightly loose causes a slow leak that appears weeks later.
  • Telling a failing pump from a bad hose by guessing leads to paying for a part that was fine.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E24E24 questions
Why is there a bad smell along with E24?

Water that sits in the tub grows odors from the trapped food. Cleaning the filter and running the drain usually removes it, but if the water stays, the blockage is deeper.

Is E24 covered under warranty?

Manufacturer coverage depends on your purchase date and terms. Blocked filters are normally an upkeep matter. Our own repair work carries a 30-day workmanship warranty, with a written price first.

Can I use the dishwasher if it drains slowly?

We would not. Slow drainage means dirty water is left behind and may back up. Clean the filter, and if it persists, call us before running more loads.
