Possible cause

Solution

The general electrical 

system is malfunctioning.

Defective fuse.

The automatic safety switch or 

circuit breaker has tripped.

Check the fuse in the main fuse 

box and change it if it is damaged.

Check the main control panel to 

see if the automatic safety switch 

or circuit breaker has tripped. 

The automatic on 

function does not work.

There may be food or cleaning 

products stuck between the 

ignition sparkers and the 

burners.

The burners are wet.

The burner covers are not 

correctly positioned.

The appliance is not earthed, is 

not correctly connected or the 

earth wire is faulty.

uniform.

not empty.

Open all intermediary valves.

gas.

A gas tap has been left on. 

There may be a leak in the gas 

cylinder coupling.

of the burners are not 

working.

The control knob was not held 

down for long enough. 

The grooves on the diffuser are

longer. Clean the grooves on the 

diffuser.
