Troubleshooting

8.1

Temporary and permanent faults

There are two types of notices displayed: temporary or permanent. The first notice shown on the display is a letter followed by a
two-digit number. The letter indicates the type of fault: Temporary (A or H) or permanent (E). The number indicates the group in
which the fault that has occurred is classified according to its impact on safe and reliable operation. The second notice consists
of a two-digit number that indicates the type of fault which has occurred (see the following fault tables).
TEMPORARY FAULT (A/H.x.x.)
A temporary fault is shown on the display by the letter "A" or "H" followed by a number (group). A temporary fault is a type of
fault that does not cause a permanent stoppage of the boiler. It has the following characteristics:
A: The appliance continues to operate. It disappears as soon as the cause has been resolved.
H: Disappears when the error condition is removed, in some cases even after 10 minutes.
PERMANENT FAULT (E.x.x)
A permanent fault is shown on the display by the letter "E" followed by a number (group). Press the RESET key for 1 second. If
faults are shown frequently, contact a qualified technician.
E: Stoppage, RESET required.
