Fault
Possible Cause
Remedy
Main Burners do not ignite
Check power is supplied to
appliance.
Check pan is flat and that tilt
microswitch is closed.
Check thermostat setting is
correct and gas control knob on
main burner is set to 'ON'
position.
Turn ‘On’ power.
Adjust microswitch so that micro-
switch is activated when pan is
fully down in flat (cooking
position).
Call service provider.
No pan filling water available.
(Manual water fill valve has an
electrical solenoid isolating valve
fitted to supply side of water
supply plumbing in appliance.
Shut-off valve only opens water
supply to manual valve when pan
is in ‘DOWN’ position.
With pan in ‘Down’ position and
main water supply ‘ON’ and
manual water control valve set to
max flow, check solenoid valve
has electrical power across its coil
terminals.
If solenoid coil has power, but no
water available on turning manual
valve, check coil for open circuit,
short circuit and for solenoid coil
burn-out.
If solenoid coil is satisfactory,
disconnect water connection and
check inlet filter screen for foreign
matter blockage.
If there is no voltage to solenoid
coil.
Replace solenoid.
Clean and refit inlet filter.
Check water valve microswitch.
Check for electrical fault in pan
lift microswitch circuit. A fault
here is likely to also cause main
burner to fail.
Call service provider.
Over-temperature thermostat cuts
out
Over-temperature thermostat
faulty.
Control thermostat not
maintaining set temperature.
a. Thermostat out of

thermostat leads, on
temperature rise. If circuit does
not open, replace thermostat.
Check connections on gas
control are correct. If correct,
replace gas control valve.
