If your Bosch dishwasher suddenly stops working and flashes the error code E22, it can be frustrating. This error means there is a filter blockage inside your dishwasher. Don’t worry - I’m here to guide you through understanding what causes this issue and how to fix it step-by-step. With a little patience and some simple tools, you can get your dishwasher back to working perfectly in no time.
What Does Bosch Dishwasher Error Code E22 Mean?
The E22 error code on a Bosch dishwasher indicates a problem with the drainage system. Specifically, it points to a filter blockage that is preventing water from draining properly. When the dishwasher detects that water is not draining as it should, it triggers this error to protect the appliance from damage.
The filter is a small but crucial part of your dishwasher. It catches food particles and debris during the wash cycle to prevent them from clogging the drain pump or pipes. Over time, this filter can get clogged with leftover food, grease, or other debris, causing the dishwasher to stop draining and display the E22 error.
Understanding this helps you know exactly where to look and what to clean to fix the problem.
How to Check and Clean the Bosch Dishwasher Filter
Cleaning the filter is the most common and effective way to resolve the E22 error. Here’s a simple, step-by-step guide to help you do it safely and efficiently:
Turn off the dishwasher and unplug it
Safety first! Always disconnect the power before working on your appliance.
Open the dishwasher door and remove the bottom rack
This gives you clear access to the filter area at the bottom of the dishwasher.
Locate the filter assembly
The filter is usually a round or cylindrical piece at the base of the dishwasher tub. It may have a handle or tabs to twist and remove it.
Remove the filter carefully
Twist or lift the filter out according to your model’s instructions. Be gentle to avoid damaging any parts.
Clean the filter thoroughly
Rinse the filter under warm running water. Use a soft brush or an old toothbrush to scrub away stuck food particles and grease. Avoid using harsh chemicals.
Check the filter housing and drain area
Look inside the filter housing for any debris or blockages. Remove any visible dirt or food scraps.
Reinstall the filter
Once clean, place the filter back into its position and secure it properly.
Replace the bottom rack and close the door
Plug the dishwasher back in and run a short cycle to test if the error is cleared.

When to Check the Drain Hose and Pump for Blockages
Sometimes, the filter is not the only culprit. The dishwasher’s drain hose or pump can also get clogged, causing water to back up and trigger the E22 error. Here’s how to check these parts:
Inspect the drain hose
The drain hose connects your dishwasher to the sink drain or garbage disposal. Look for kinks, bends, or visible blockages. Detach the hose carefully and flush it with water to clear any clogs.
Check the drain pump
The drain pump is located near the filter area. If you hear unusual noises or the dishwasher still won’t drain after cleaning the filter and hose, the pump might be blocked or faulty. Remove any debris you find, but if the pump is damaged, you may need professional help.
Regularly checking these parts can prevent future blockages and keep your dishwasher running smoothly.
Tips to Prevent Bosch Dishwasher Filter Blockage
Prevention is always better than cure. Here are some practical tips to avoid the E22 error and keep your dishwasher in top shape:
Scrape off large food scraps before loading dishes
This reduces the amount of debris that reaches the filter.
Use the dishwasher’s pre-rinse cycle if available
This helps wash away loose particles before the main wash.
Clean the filter monthly
Make it a habit to remove and clean the filter regularly to prevent buildup.
Avoid overloading the dishwasher
Overcrowding can block water flow and cause debris to accumulate.
Use recommended dishwasher detergents
Some detergents help break down food particles better, reducing filter clogging.
By following these simple steps, you can extend the life of your dishwasher and avoid inconvenient breakdowns.
