What Causes Bosch Dishwasher E22 Error

What Causes Bosch Dishwasher E22 Error

The filter in a Bosch dishwasher consists of two main parts: the main filter and the microfilter. 

The main filter catches bigger food particles and debris, while the microfilter takes care of the smaller ones, making sure they don’t circulate back into the dishwasher.

Over time, the filter can get all gunked up with residue, grease, and food particles, causing it to lose efficiency. 

When the filter gets too dirty or clogged, it restricts water flow and messes with the drainage, leading to that annoying E22 error.

To keep things running smoothly and avoid the E22 error, it’s crucial to give the filter some regular TLC by cleaning and maintaining it.
