Bosch Dishwasher Error Code E22: How to Fix It

The Logic Verdict

My Take: This is the “you didn’t realize there’s a filter at the bottom of your dishwasher” error. This filter can get clogged easily and will generally be the culprit behind this error. You might get coaxed into replacing a whole pump but 9/10 times it’s your filter. You can clean it simply with some warm water and dish soap. If you want a new one, it’s linked below.

What It Means

The E22 code indicates Residual Water in Sump. The dishwasher is struggling to drain completely, usually because the path is blocked by debris.

Common Causes

1. Clogged Filter (Most Common)
2. Blocked Drain Pump Impeller
3. Kinked Drain Hose

Step-by-Step Fix

1. Remove Filter: Twist the cylindrical filter at the bottom of the tub and pull it out.
2. Clean Thoroughly: Wash it with hot soapy water. Use a toothbrush to scrub the mesh.
3. Check Impeller: While the filter is out, check for any glass or seeds blocking the pump cover.
