Bosch Dishwasher Error Codes E01 – Heating Issue

What is a Bosch dishwasher E15 error code? The E15 error code signifies water leaking from the dishwasher. This could be due to a faulty float switch, a damaged door seal, or a leaking hose.

Error Code E22 – Dirty Filter
When you see the E22 error code, it’s time to clean your dishwasher’s filter.

To resolve this, remove the filter and rinse it thoroughly under running water. Make sure to place it back correctly before resuming your dishwasher’s operation.

Bosch Dishwasher Error Codes E24 – Drainage Problem
The E24 error code indicates a dishwasher drainage problem, which could be due to a clogged drain hose or a malfunctioning drain pump.

If the hose is clear, the issue could be with the drain pump, and it’s recommended to consult a professional for further assistance.
Error Code E25 – Circulation Pump Issues
This Bosch Dishwasher Error Code signals an issue with the circulation pump. The circulation pump is responsible for circulating water during the wash cycle.
