Bosch Dishwasher E24 Dishwashers by Bosch are renowned for being dependable and of the highest calibre. Wear and tear will nevertheless continue to happen over time and result in a number of problems. The “E24” error number indicates a problem with the dishwasher’s drainage if it appears on your Bosch dishwasher. A clogged filter is typically the problem. The drain hose, drain pump, or drain pump cover are most likely to blame if the problem continues even after the filter has been cleaned. To resolve the problem, take the following actions.

1. Clear the Filter

The bottom of your Bosch dishwasher should include a filter. Remove the spray arm and bottom dish rack to find the filter. To remove the filter from the dishwasher, turn the top of the filter. Check the dishwasher’s handbook for filter removal instructions if the filter cannot be removed easily. Remove the dishwasher’s filter, then wash it with warm, soapy water. Examine the drain pump while you have the filter out.

2. Examine the Drain Pump.

The dishwasher ought to show an E24 error code if there is a problem with the drain pump. If clearing the filter hasn’t worked to resolve the E24 error code, the drain pump may be clogged and to blame. The E24 error code can also be brought on by a loose pump lid.

When the filter is removed from the majority of Bosch dishwashers, the pump cover and pump can be examined and cleaned of obstructions. When inspecting the pump for obstructions, it is advised to wear safety gloves because the pump casing may include jagged debris, such as shattered glass.

The pump cap can be detached with a teaspoon. Reach down and look for an obstruction with the cover off. Additionally, make sure the impeller of the pump may freely rotate. The drain pump is broken if the impeller has trouble rotating.

It might also be feasible, depending on the model, to lift the float to see if the drain pump is operational. The filter and the float are close by. If the drain pump is functional, the dishwasher may activate it when you pull the float up, depending on the model. When lifting the float, be careful not to let your hands get near the drain pump. Move on to the following step if the E24 issue keeps occurring.

If you can’t get to the pump, proceed to step 6 and take off the bottom kick plate.

3. Examine any kinked hoses.

The dishwasher may not be able to drain, which would result in the E24 error, if a hose is kinked. Examine the drain pipe to make sure it is not kinked before continuing. Be careful that the drain hose can be set up with a high loop if it is not attached to an air gap to prevent wastewater from returning to the dishwasher. It’s unlikely that the high loop is what’s creating the E24 problem; it’s needed to stop other problems from happening.

4. Make the dishwasher sparkle.

Run a cycle with a dishwasher cleaning solution if the dishwasher is still draining and the E24 error has not been fixed. It is possible to buy and use a dishwasher cleaning made by Bosch or a comparable product. Baking soda can also be used to dissolve any blockages in a cleaning solution that is made of white vinegar. If the dishwasher’s interior contains stainless steel components, avoid using a bleach-based cleaning solution.
Prior to running a cleaning solution through the dishwasher, you may want to perform step 5 and disconnect the drain line to look for obstructions.

Baking soda and vinegar are used to clean:

  • Fill a bowl that is dishwasher-safe with 1 cup of distilled white vinegar.
  • Position the dishwasher’s top rack over the bowl. As soon as the dishwasher starts its cycle, the vinegar will drain out, so avoid pouring it directly into the appliance.
  • Start the dishwasher’s regular cycle without any dishes or detergent.
  • After a brief hot cycle, add a cup of baking soda to the dishwasher.
    Go to the following step if the E24 error code cannot be fixed.

5. Inspect the S-Trap and Air Gap.

The S-trap, garbage disposal, or air gap under the sink should receive the dishwasher’s drain hose. You might discover the obstruction that’s producing the E24 error if you disconnect the drain pipe. The problem might also be fixed by cleaning the air gap, garbage disposal, or S-trap.

6. Inspect the Drain Hose and Drain Pump
The dishwasher’s drain hose may be obstructed where it links to the drain pump if the aforementioned fixes have not eliminated the E24 error number. Additionally, the drain pump can be broken or blocked. However, a faulty drain pump ought to provide an E25 error code.

A thorough cleaning of any obstructions is also possible after removing the hose from the dishwasher. Check for any additional problems that would suggest the control board is faulty and resulting in the E24 error before gaining access to the drain pump and removing the drain hose.

In order to get to the drain pump and hose:

  • Disconnect the water supply and power to the dishwasher for safety’s sake.
  • Take out the screws holding the dishwasher’s kick panel at the front bottom.
  • In case it’s required, take the wiring harness out.

Analyze the drain pump:

If there is an obstruction or the pump motor fails, the drain pump may not be able to drain the dishwasher. It is important to make that the impeller of the pump can easily turn and that there are no blockages. It’s likely that the drain pump will need to be replaced if the impeller on the pump cannot turn freely. Either remove the drain pump from the dishwasher and test it for continuity after, or test it with a multimeter set to the ohms setting. A replacement will be required if the motor’s continuity test comes up negative.

Analyze the drain hose:

  • Look for the drain hose, which ought to be attached to the drain pump. The recirculation hose on the majority of types will also include a place where blockages may be checked.
  • To catch any possible spilled water, place a towel or container underneath the hose.
  • Use pliers to release the wire clamp, then unplug the drain pipe from the drain pump. With the use of a drain snake, try to remove the obstruction.
  • If necessary, unplug the sink’s drain pipe.
  • Use a drain snake or other drain cleaning instrument, or clean the drain hose with hot water to remove soap buildup.
  • Attach the dishwasher’s drain hose back to the unit.

The E24 problem should be fixed at this point. Control board issues could arise if the error keeps happening. To fix the problem, speak with a qualified expert.
