Troubleshooting Drainage Issues in Bosch Dishwashers

If cleaning the filter doesn’t resolve the E22 error code on your Bosch dishwasher, there may be other underlying drainage issues causing the problem. Troubleshooting these drainage problems can help get your dishwasher back up and running smoothly. Here are some steps to troubleshoot and resolve common drainage issues:

1. Check the dishwasher basin for debris: Debris or food particles can obstruct the drainage system, causing water to accumulate. Inspect the basin and remove any visible debris that might be blocking the drainage path.
2. Inspect the drain hose: The drain hose connects the dishwasher to the plumbing system. Make sure the drain hose is not kinked, twisted, or damaged in any way. Clear any blockages by gently running a long, flexible brush through the hose.
3. Check the drain pump: The drain pump is responsible for removing water from the dishwasher. Locate the drain pump and make sure it is free of debris or obstructions. If necessary, clean the pump impeller and remove any blockages.
4. Verify control board functionality: In some cases, a faulty control board can trigger a false E22 error code. Check if the control board is operating correctly. If you suspect a control board issue, it’s best to seek professional assistance for further diagnosis and repair.
5. Address calcium buildup: Excessive calcium buildup can contribute to drainage issues, especially in areas with hard water. Regularly clean the dishwasher filter and consider using a descaler or dishwasher cleaner to remove calcium deposits.

By following these troubleshooting steps, you can effectively resolve common drainage issues that may be causing the E22 error code on your Bosch dishwasher. If the problem persists or if you’re unsure about performing any repairs on your own, it’s recommended to contact a trained technician for assistance. Maintaining proper dishwasher drainage is essential for optimal performance and longevity.
