Gas error
Should a gas error occur error code E 14 will be
displayed, fig. 1.
In general gas errors occur due to supply shortage
either if there is a gas failure or the gas pressure is
too low.
Other errors which can cause E 14 :
• Ignition failure. Check the distance between
the electrodes on one burner, fig. 2.
The distance must be 3.5 mm (± 0.5 mm).
The distance above the burner must be 5 mm
(± 0.5 mm).
• The sensor S on the other burner (the ionization
must detect the flame), fig. 3.
Control measuring the ionization current
1. Demount wire with quick connector A.
2. Connect an ammeter/gauge between the quick
connector A and the ignition electrode B, fig. 4.
3. Start the dryer on High heat.
4. Measure the current between the quick
connector A and the ignition electrode B.
The current must be at least 0.9 μA DC.
