Understanding these potential causes can help in troubleshooting the Bosch dishwasher E22 error and getting your appliance back up and running smoothly.

Clogged Filter

Common causes of the Bosch dishwasher E22 error code:

Clogged or Blocked Filter: A common culprit for the E22 error code is a clogged or blocked filter. When the filter is obstructed, it can lead to drainage issues and trigger the error code on your Bosch dishwasher.
Drain Hose Obstruction: An obstruction in the drain hose can also result in the E22 error. Ensure that the drain hose is free from any blockages or kinks that may impede proper drainage.
Water Supply Issues: Insufficient water supply or low water pressure to the dishwasher can sometimes trigger the E22 error code. Check that the water inlet valve is fully open and that there are no issues with the water supply to the appliance.
Faulty Drain Pump: A malfunctioning drain pump can cause drainage problems and lead to the E22 error on your Bosch dishwasher. If the drain pump is defective or obstructed, it may need to be repaired or replaced.
Excessive Suds: Using the wrong type or excessive amount of detergent can create too many suds during the wash cycle, affecting proper drainage and resulting in the E22 error. Always follow the manufacturer’s guidelines for detergent usage.

Drain Pump Issues

Encountering the E22 error code on your Bosch dishwasher can be quite frustrating, especially if you’re in the middle of a cleaning cycle. Understanding the common causes of this error can help you troubleshoot the issue effectively.

Another potential culprit is an obstruction in the drain hose. Ensure that the drain hose is clear of any blockages or kinks that could hinder proper water flow.
Issues with water supply, such as low water pressure or inadequate water reaching the dishwasher, can also lead to the E22 error. Check that the water inlet valve is fully open and that there are no water supply issues to the appliance.
A faulty drain pump is another common cause of the E22 error. If the drain pump is malfunctioning or blocked, it can result in drainage issues and trigger the error on your Bosch dishwasher.
