Bosch Washer - E28 Error Code
The washer detected abnormal flow meter readings.
Meaning
The washer detected abnormal flow meter readings.
The Bosch E28 and F28 error codes indicate that the washer’s flow meter is reporting inconsistent or invalid readings. The flow meter measures the exact amount of water entering the washer. If the readings do not match expected values—due to blockages, faulty sensors, or wiring issues—the washer triggers E28 to prevent incorrect water levels and cycle failures.
