Siemens Dishwasher Error Code E22 Meaning and Possible Fixes
Siemens Dishwasher Error Code E22
If your Siemens dishwasher displays error code E22, this indicates that the filter system is soiled or clogged.
Siemens dishwashers use a filter system at the base of the wash chamber to catch food debris and prevent it from re-circulating during the wash cycle. If the filter becomes heavily blocked, the appliance will display the E22 error code.

What the E22 Error Means
The E22 error code indicates that the filter system in your Siemens dishwasher is soiled or clogged. In most cases this can be resolved by removing and cleaning the filter. This is one of the most straightforward error codes to fix yourself.
Common Reasons This Error Appears
Blocked filter
Food debris, grease and particles accumulate in the filter over time. Without regular cleaning the filter will become sufficiently blocked to trigger this error.
Infrequent filter cleaning
The dishwasher filter should be cleaned regularly. If it has not been cleaned for a long time, a significant buildup of debris will have occurred.
Large food particles
Scraping dishes before loading them into the dishwasher helps prevent excessive buildup in the filter. Large food particles can block the filter more quickly.
Blocked sump area
The sump area beneath the filter may also have accumulated debris that is contributing to the blockage.
Safe Checks You Can Try
Clean the filter system
Remove the filter from the base of the dishwasher. Most Siemens dishwashers have a cylindrical filter and a flat mesh filter. Rinse both thoroughly under running water, using a soft brush to remove any stubborn debris. Check the sump area beneath the filter for any foreign objects and remove them before refitting the filters.
Run a maintenance wash
After cleaning the filter, run an empty hot cycle with a dishwasher cleaner to help clear any residue from inside the appliance.
Restart the dishwasher
Switch the appliance off, wait a few minutes, then switch it back on and start a new cycle.
