Bosch Dishwasher Error Code E24 Meaning, Causes, and Troubleshooting
The error code E24 mostly means that your Bosch dishwasher is having difficulty draining. So, you should check it for possible drainage issues. Remember, if your dishwasher doesn’t drain well, it won’t clean appropriately, as the dirty water will sit in the tub.
Overall, here are the likely causes of the error code E24 on a Bosch dishwasher and their troubleshooting:
1. Blocked Drain Hose
It could be that your dishwasher isn’t draining because of a blockage in the drain hose. That’s likely to happen if the drain filter fails to catch food debris and other clogs. So, you’ll need to disconnect and inspect the hose.
Troubleshooting
It’s best to clean a blocked drain hose with vinegar and baking soda, and that requires these steps:
- First, unplug the dishwasher and then disconnect its water supply
- Disconnect the drain hose and inspect it for blockages
- Pour a vinegar-baking soda mixture (1 cup each) into the drain hose and allow it to sit for 10-15 minutes
- Run hot water through the drain hose to wash away the already dislodged clog
- Reattach the drain hose and connect its water supply
- Run the Quick Wash cycle on your dishwasher before you start to use the regular cycle
2. Clogged Drain Filter
Remember, before food debris, grease, and other clogs can block the drain hose, they’ve to pass through the drain filter. So, the drain filter could be the first component to clog, and when it does, that could result in the E24 error code.
Troubleshooting
If the drain filter is clogged, you must clean it, and you’ll need to use warm soapy water. Here’s how to do it:
- Disconnect the dishwasher
- Detach the bottom tray to access the filter and pull it out by twisting it
- Wash the filter with a soft brush or sponge and warm soapy water
- Rinse it clean and reinstall it
3. Undetached Knock-Out Plug
During a new Bosch dishwasher installation, the knock-out plug must be removed. If left there, it’ll block the garbage disposal and only interfere with the drainage. Remember, the knock-out plug is a plastic cover on the garbage disposal that aids in transporting the dishwasher.
Troubleshooting
You should remove the attached knock-out plug from the garbage disposal. That may require a hammer and screwdriver to tap out the knock-out plug.
4. Kinked or Leaky Inlet Hose
Your Bosch dishwasher may display the error code E24 if the inlet hose is either kinked or leaky. The latter involves direct damage to the inlet hose, while the former often involves squeezing the inlet hose too much, especially when pulling the dishwasher too close to the wall.
Troubleshooting
Pull out the dishwasher from the wall to clear any kinks. Straighten them out. And if the inlet hose is damaged, replace it.
5. Incorrectly Sealed Air Gap
The air gap or siphon connection prevents water backflow by creating a gap barrier. It, however, has to be adequately sealed to do that. If not, you can expect water to flow back after drainage, which may trigger the E24 error code.
Troubleshooting
Properly seal the air gap if that’s not the case. That may mean tightening it firmly.
6. Loose Pump Cover
The pump cover under the filter prevents excess water from flowing to the drain pump. However, it fails to do so when it’s loose, which overwhelms the drain pump.
The result is that an overwhelmed drain pump can’t pump out enough water, which means the dishwasher will have issues draining, which could trigger the E24 error code.
Troubleshooting
Tighten the pump cover if it’s loose to not overwhelm the drain pump with excess water.
7. Software Glitch
Lastly, the E24 error code might not appear because of a drainage issue. It could just be an electronic glitch; if so, your dishwasher needs a reset.
Troubleshooting
Consider resetting your Bosch dishwasher, and here’s how to perform the Bosch dishwasher E24 error reset:
- Turn off the dishwasher
- Plug it out for 2-3 minutes
- Plug the dishwasher back in and turn it on
- Wait to see if the fault code is still there
Remember, you can always start with the hard reset as the first troubleshooting step before looking at the discussed six. That’s because it’s easy to do and pretty fast. It’ll save you the time to unscrew anything when it’s unnecessary.
Bosch Dishwasher Not Draining
There are several reasons why your Bosch dishwasher won’t drain. The commonest ones are as follows:
- Blocked drain hose – primarily due to food debris, soap scum, and grease
- Clogged drain filter
- Kinked or damaged water inlet hose
- Undetached knock-out plug in case of a new installation
- Incorrectly sealed air gap
- Loose pump cover
Troubleshooting
In the case of a blocked drain hose or drain filter, clean them properly to eliminate the blockage. Unkink a kinked hose and replace it if it’s damaged. Remove the knock-out plug if it’s a new installation, correctly seal the air gap, and tighten the pump cover.
Bosch Dishwasher Troubleshooting E25
The error code E25 appears on a Bosch dishwasher when there’s an issue with the drainage, just like the error code E24. Often, the cause is a blocked drain hose, clogged drain filter, obstructed drain pump, or a loose drain pump cover.
Troubleshooting
Clean the drain hose, filter, or pump if they are filthy. You’ll need to use warm, soapy water and tighten the drain pump cover if it’s loose. Don’t rule out a software glitch and, thus, hard reset the dishwasher before considering the other fixes.
Bosch Dishwasher Troubleshooting E22
Expect the error code E22 to point to a drainage issue, just like E24 and E25. In that case, you should check for any of these issues:
- Obstructed drain filter
- Blocked drain pump
- Kinked drain hose
- Damaged impeller
Troubleshooting
Clean an obstructed drain filter or pump and unkink the drain hose if it’s not straight. Inspect the impeller and replace it if it’s broken. But before anything, first try to reset the dishwasher, as the error code could be a s result of a software glitch.
