5.3. Maintenance and inspection of hob components.
If the hob is operated in accordance with
these instructions, cleaned and maintained according to the description presented in sub-clause 4.1,
- then a hob that works properly does not require inspection.
6. HANDLING DEFECTS – error signaling
Please read the following guidelines before calling the manufacturer’s service technician:
-
The reheating pad heats up but does not glow during operation of the burner pad.
-
Regular bursting noise of spark generator and valve can be heard while starting up the heating
pad before gas is lit. Individual hot field may glow with varying power. These occurrences and
sounds are normal in an operating hob. The burner located under the hot field controls its
temperature through switching on and off. When low heating power setting is chosen for the hot
field, the burner will go off for a longer time, or for a shorter time in case of higher heating power,
accordingly. In case of gas pressure drop in the network or cylinder, the hob will be automatically
locked. This is signaled by the letter
“G”
.
7. CONTROLLER ALARM CONDITIONS SIGNALING
