8.2 To Service a gas Valve
Remove product top panel.
Remove circlips from each gas valve to free the microswitch assembly.
Lift off microswitches.
Unscrew the two Philips screws on the top of the gas valve.
Gently lift out the valve cone, clean with solvent.
Re-grease with high temperature grease. (e.g. ROCOL HT, Otimol HT2EP, Ragasine Moly LM).
Replace.
Move it around, remove excess grease, remove and check holes in the core or body are not
blocked, replace.
Open and close the valve several times.
Check for leaks with aerosol leak detection spray (e.g. Rocol) and re-assemble in reverse order.
9. Problem Solving Auto Re-ignition (USA & Canada
models)
9.1 Gas Doesn't Light – No Spark
Check the electricity supply.
Check spark gap is not too wide (burners sitting correctly).
Check electrodes/burners are clean (use rubbing alcohol and an old toothbrush).
Check continuity from the box to the electrode and from the burner or earthing point to the earth
connection on the box.
Check the high tension leads are not coiled, as this may result in a loss of voltage to the
electrode. (Use correct length leads and locate in correct position.)
Check for damage to the wire insulation and that the leads are not against parts that will heat up
during operation.
9.2 Gas Doesn't Light – Spark but no Ignition
Check the cooktop and regulator are set up for the correct gas type and pressure (factory set for
NG).
Check location of ignitors and make sure spark gap is not too wide.
Check the burner components including the burner cap are sitting correctly.
Check electrodes/burners are clean (use rubbing alcohol and an old toothbrush).
