Bosch Washer - E26 Error Code

The flow sensor is reporting abnormal or no readings.

Meaning

The flow sensor is reporting abnormal or no readings.

The Bosch E26 and F26 error codes indicate a malfunction in the flow sensor, which measures the amount of water entering the washer. If the sensor detects inconsistent flow, no flow, or readings outside the expected range, the washer triggers E26 to prevent overfilling or underfilling. This can be caused by clogged inlet screens, faulty flow sensors, or wiring issues.

Symptoms

  • Washer stops filling unexpectedly

  • Cycles take longer than normal
  • Washer fills too slowly or too quickly

Causes

  • Clogged inlet filters
