Errors and warnings

The water heater can have three different kinds of errors and warnings:
• General errors (see section 11.1.1), which are not displayed
• Displayed errors, which are divided in two different groups:
- Lock out errors: when the cause is removed, you can reset the error to resume
operation. The displayed code and the back-light of the display blink.
- Blocking errors: when the cause is removed, the error resets automatically to
resume operation. The code is displayed continuously and the back-light of the
display blinks.
Errors are reported on the display as follows:
- Line one: an error code and a brief description. The code consists of a letter
and two digits.
- Lines two, three and four: a long description, alternating with a recommended
action. See the figures. The first shows a possible error, the second shows the
appropriate checking action.
• Displayed warnings (see section 11.1.3)
Note
It is possible to view the error history of the water heater, refer to Error history (see
section 9.2.2).
