Bosch Dishwasher Error Code E24

Bosch Dishwasher Error Code E24

Bosch dishwashers have a stellar reputation for durability and dependability. However, occasionally your Bosch dishwasher may have an issue that produces an error code, such as the Bosch Dishwasher Error Code E24, even with the best Bosch dishwasher technology.

According to Bosch, an Bosch Dishwasher Error Code E24 error means the dishwasher’s drain filter or pump is clogged, preventing water from leaving the appliance. However, other factors, such as a plugged drain hose, kinked hoses, an obstructed air gap, or a garbage disposal with its plug still in place, might also contribute to this mistake.

If the problem persists after these parts have been checked, the error code could be the result of a faulty control board.

Helpful Tips to Solve the Problem Bosch Dishwasher Error Code E24

If your Bosch dishwasher has displayed the Bosch Dishwasher Error Code E24, read on for help troubleshooting and fixing the issue.

Before servicing the dishwasher, be sure the power has been turned off.

Method 1. Be Sure it’s Not Just a Glitch.

The control panel of the dishwasher can experience bugs from time to time, resulting in erroneous error codes. For one-time error codes, turning off the dishwasher’s electricity for five minutes usually does the trick.

To remove water from the dishwasher, you can either let it drain naturally or reset it by holding the start button down, however this may not work for all models. If you press the start button and nothing happens, there is a drainage problem that needs to be fixed and it is not a malfunction.

Method 2.  Make Sure No Hoses are Twisted.

A kink in a hose might prevent water from entering or leaving the dishwasher. Even if a kinked hose is unlikely to be the reason for the Bosch Dishwasher Error Code E24, it is still a good idea to inspect the hoses before going on to the other dishwasher parts.

Method 3. Clean the Sump and Filter.

Having the sump and filter cleaned out usually fixes the Bosch Dishwasher Error Code E24 problem. The filter for a dishwasher can be found in the middle of the dishwasher’s sump or tub.

Removing the bottom dish rack and spray arm will likely be required to gain access to the sump and filter, as will draining the water that the error code is blocking from draining.

Turning the filter counter-clockwise on most models will disable it. When the filter is no longer in place, it can be cleaned thoroughly with soap and water.

Before continuing on to inspect the pump and cover, make sure there is nothing blocking the drain at the bottom of the dishwasher.

Method 4.  Examine the Drain Cap and Pump

Most Bosch dishwasher models include a filter at the bottom, and the drain pump may be accessed and cleaned by removing the pump cover. In order to access the drain pump and clean any clogs, you may need to take the dishwasher out and remove the appropriate panels, or remove the kick plate.

If the drain pump can be accessed from the bottom of the dishwasher, verify that the cover is not ajar, as this could be the source of the Bosch Dishwasher Error Code E24. An incorrectly fastened cover is a likely cause of the malfunction indicated by the error code.

After that, you need to make sure there are no obstructions in the pump. A pull tab may be present on some models to access a secondary, smaller drain pump cover. The drain pump itself may be hidden under a small cover, but the impeller can be inspected and any obstructions cleared away if the cover is removed.

The impeller should be rotatable. Not turning means the drain pump is broken and needs to be replaced. You’ll need to take out the drain pump and check it with a multimeter to see whether it’s broken.

After you’ve finished cleaning, replace the filter and pump covers. If a blockage was discovered, the dishwasher should be tested to check if the problem has been remedied. You should proceed to the next step if the problem persists.

Method 5. Observe the Drain Hose

The drain hose from the dishwasher should lead to the pipe running beneath the sink. Whether your dishwasher is connected to an air gap, garbage disposal, or S-trap depends on your plumbing setup.

Clogging of the drain hose connection under the sink is another common reason for the Bosch Dishwasher Error Code E24. To check for obstructions, you’ll need to unfasten the clamp holding the drain hose in place. Disconnect the hose and clear out the obstruction once you’ve located it.

Method 6. Examine the S-trap, Air Gap, and Garbage Disposal for Obstructions.

If the Bosch Dishwasher Error Code E24 message appears and the drain line from your dishwasher is attached to an air gap, check the air gap for any obstructions. It may be possible to remove the air gap’s cap and inspect it for obstructions, depending on the design.

Make that the stopper has been removed from the drain hose connection between the dishwasher and the garbage disposal if you just installed the dishwasher.

Some people who own Bolsch dishwashers claim that if they open and close the door quickly after the cycle has begun, the appliance will mistakenly conclude that everything is alright. Be cautious, though, that ignoring the dishwasher’s error message could lead to much more severe harm down the road, depending on the nature of the problem.


The Bosch Dishwasher Error Code E24 should have been removed and the underlying problem fixed if you had followed the preceding six steps. If the error message still appears, it may be time to consult a professional.

To get to the drain pump, you’ll probably have to take the dishwasher apart. If replacing the drain pump isn’t necessary, the issue is probably with the circuit board.
