Convotherm E26

What does Convotherm E26 mean?

E26 reports a failure of the steam generator's safety temperature limiter sensor. The manual lists a safety temperature limiter sensor fault in the steam generator as the cause and directs the remedy to customer service. This sensor is part of the steam generator's over-temperature protection, so the control flags E26 when it cannot rely on that safety reading.

Symptoms

• Display shows error code E26

When to call a professional

E26 involves a safety temperature limiter sensor in the steam generator, which is a protective device.
