When to Call a Professional

Call a professional if the error persists after cleaning, if you find damaged filters that need replacement, if there are signs of a drain hose blockage, or if you're uncomfortable performing the cleaning yourself. Also contact a technician if you notice unusual noises, leaking, or if the sump area shows signs of damage.

Frequently Asked Questions

How often should I clean my Bosch dishwasher filters to prevent E22 errors?
Clean your dishwasher filters at least once a month with regular use, or every two weeks if you frequently wash heavily soiled dishes. Pre-rinsing dishes and scraping off large food particles can help extend the time between cleanings.
Can I run my Bosch dishwasher with the E22 error showing?
No, you should not continue using the dishwasher when the E22 error appears. The blocked filter prevents proper drainage, which can lead to poor cleaning performance, water damage, or further mechanical problems.
What causes the filters to get blocked so quickly in my Bosch dishwasher?
Common causes include not pre-rinsing dishes, washing items with heavy food debris, using incorrect detergent amounts, or washing non-dishwasher safe items that may break down. Grease and starchy foods are particularly problematic for filter blockages.
Is the E22 error the same as other Bosch dishwasher drain errors?
While E22 specifically indicates blocked filters, other drain-related errors like E24 or E25 may indicate different drainage issues such as blocked drain hoses or garbage disposal problems. Each error requires specific troubleshooting steps.
Will cleaning the filters fix the E22 error permanently?
Cleaning the filters will typically resolve the immediate E22 error, but regular maintenance is needed to prevent it from recurring. Establishing a monthly cleaning routine and proper dish preparation habits will help prevent future occurrences.
