Error Code: E22 Difficulty: Easy
Problem: Blocked filter.
How to Fix E22 Error (Step-by-Step)
- Open the dishwasher door and slide the bottom rack completely out of the tub.
- Locate the filter assembly in the bottom center of the dishwasher floor.
- The assembly usually consists of two parts: a cylindrical micro-filter and a flat coarse filter. Twist the cylindrical filter counter-clockwise to unlock it.
- Lift out the cylindrical filter and then remove the flat mesh filter plate that was underneath it.
- Thoroughly rinse both filter components under warm running water. Use a soft brush to gently remove any food particles or built-up grime.
- Clean any debris from the sump area where the filter sits.
- Reinstall the flat filter first, ensuring it sits flush, then place the cylindrical filter back and twist it clockwise until it locks securely in place.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Dishwasher
drain or filter fault: This fault path should start with the filter, sump, drain pump, and hose before any control diagnosis.
- Clean the filter assembly and check the sump for debris that can block the drain-pump impeller.
- Inspect the drain hose for kinks or a blocked sink/disposal connection, especially after recent plumbing work.
- If water remains after those checks, inspect the drain pump, wiring, and control output before replacing parts.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
