Troubleshooting Bosch E24 error
Before you begin troubleshooting, make sure to disconnect your dishwasher from the power source to ensure safety.
Reset Bosch dishwasher
To reset your Bosch dishwasher if you have a one time type of malfunction in the dishwasher’s control panel. If the control panel has a temporary issue it may result in an incorrect error code being displayed. To address this isolated issue, it is advisable to disconnect the dishwasher’s power supply for a duration of 10 minutes, which should resolve the problem and reset the dishwasher.
An alternative solution would be to press and hold the start button. This action should not only reset the dishwasher but also initiate the draining cycle to eliminate any water present within the appliance. If the start button does not prompt the water to drain, it suggests that the issue is not a mere one time issue, but rather a drainage problem that requires further attention.
Inspect and clean the filters
Food debris and other particles can accumulate in the filters, obstructing the water flow and preventing proper drainage.
- Remove the bottom rack from the dishwasher.
- Locate the filter assembly at the bottom of the dishwasher.
- Turn the filter assembly counterclockwise and lift it out.
- Clean the filters under running water, using a soft brush if necessary.
- Reinstall the filters and secure them by turning clockwise.
How often should I clean the filters in my Bosch dishwasher? To maintain optimal performance, clean the filters at least once a month or more frequently if you notice a decrease in cleaning efficiency.
Check the drain pump
Blocked drain pump: A foreign object or buildup in the drain pump can prevent the water from being pumped out effectively.
- Locate the drain pump cover at the bottom of the dishwasher.
- Remove the cover by turning it counterclockwise.
- Inspect the drain pump for any debris or foreign objects and remove them.
- Reinstall the drain pump cover and secure it by turning clockwise.
Faulty drain pump: If the drain pump is not functioning correctly, it may not be able to pump out the water as required.
How do I know if my drain pump is faulty? If you’ve tried the troubleshooting steps and the dishwasher still doesn’t drain properly, the drain pump could be faulty. Consult your user manual for instructions on testing and replacing the pump.
Examine the drain hose
Kinked or clogged drain hose: A kink in the drain hose can impede water flow, while a clog can completely block it.
- Disconnect the drain hose from the dishwasher and the sink or garbage disposal.
- Check for any kinks in the hose and straighten them out.
- Use a long, flexible brush or a plumber’s snake to clear any clogs in the hose.
- Reconnect the drain hose to the dishwasher and the sink or garbage disposal.
How can I prevent kinks in the drain hose? Ensure there’s enough space behind your dishwasher for the hose to run without sharp bends. Additionally, avoid pushing your dishwasher too close to the wall.
Check the control board
Malfunctioning control board: In rare cases, a faulty control board can cause the E24 error by not sending the correct signals to the drain pump. If all else fails, consider contacting a professional technician to inspect and repair the control board.
Can I fix a malfunctioning control board myself? Repairing a control board typically requires specialized skills and equipment. It’s best to consult a professional technician if you suspect the control board is the issue.
NOTE: Dishwasher recently installed? If it is connected to a garbage disposal make sure the plug has been taken out where the garbage disposal connects to the drain hose as it will not drain.
