Bosch Dishwasher Error Code E22
Residual water in the sump — filter or impeller area blocked
E22 means water remains in the sump after the drain step (distinct from E24/E25, which fire during draining). The filter unit is dirty or the area around the impeller is clogged so the last of the water can't reach the pump. Standing water in the filter well after every cycle is the classic symptom.
