What is E22 on Bosch Dishwasher? Quick Fix Guide!

Understanding the E22 Error Code in Bosch Dishwashers
Definition of the E22 Error Code
The E22 error code on a Bosch dishwasher is an alert that signals an issue with the dishwasher’s filtration system.
Specifically, it indicates that there is a blockage preventing water from filtering and draining properly. This error requires the user’s attention to ensure that the dishwasher can continue to operate efficiently.
Common Reasons for the E22 Error
Residual Water in the Sump
One common cause for the E22 error is residual water remaining in the sump, which is the area below the dishwasher’s filter. This can occur if the dishwasher cannot drain water effectively due to a clog or a malfunction in the drainage system.
Filter Blockages
Filter blockages are another frequent culprit. Over time, food particles, grease, and other debris can accumulate in the filters, leading to reduced water flow and eventual blockage. This can trigger the E22 error code and impact the dishwasher’s performance.
Waste-Water Pump Issues
Problems with the waste-water pump, which is responsible for ejecting water from the dishwasher, can also lead to the E22 error. If the pump is obstructed or has become faulty, it may fail to remove water efficiently, resulting in the error.
Troubleshooting the E22 Error
Step-by-Step Guide to Cleaning the Filters
Resolving the E22 error often begins with cleaning the dishwasher’s filters. First, remove the bottom rack to access the filters.
Then, twist and lift out the cylindrical filter followed by the flat fine filter underneath. Rinse them under running water and gently scrub with a soft brush to remove debris. Reinstall the filters, ensuring they are locked in place.
Checking and Cleaning the Waste-Water Pump
If cleaning the filters does not resolve the error, inspect the waste-water pump. Remove any covers or panels to access the pump, and check for obstructions such as food particles or glass shards.
Clear out any debris and verify that the pump impeller can rotate freely before reassembling the dishwasher.
Inspecting the Dishwasher Sump for Trapped Debris
Another critical area to inspect is the dishwasher sump. Look for trapped debris that might be causing a blockage. Remove any objects you find and clean the area thoroughly to ensure proper drainage.
Resetting the Dishwasher After Addressing the Issue
After addressing potential blockages, reset the dishwasher to clear the E22 error code.
This can typically be done by turning off the power to the dishwasher for a short period, then turning it back on. Check the user manual for specific reset instructions for your model.
Preventing Future E22 Errors
Routine Maintenance Tips for Bosch Dishwashers
Regular maintenance is key to preventing the recurrence of the E22 error. Clean the filters and inspect the sump area monthly.
Running a dishwasher cleaner through a cycle can also help clear out any hidden residue. Ensure the appliance is serviced according to the manufacturer’s recommendations.
Best Practices for Loading the Dishwasher to Prevent Blockages
Properly loading the dishwasher not only ensures clean dishes but also helps prevent blockages. Avoid overloading and place items so that water can circulate freely. Make sure that large items do not obstruct the spray arms or the filters.
Recommendations for Dishwasher Detergents and Additives to Reduce Residue Buildup
Using the right detergents and additives can significantly reduce the likelihood of residue buildup.
Choose a high-quality detergent and consider using a rinse aid to help keep the filters and pump clear. Hard water conditions may require additional additives to prevent mineral buildup.
