7. Troubleshooting
7.1. The controller cannot be switched on
⇒ Check if the controller has been connected to the switch cabinet of the kiln.
⇒ Check if the kiln is connected to the mains supply.
⇒ Check the micro-fuse on the switch cabinet of the kiln. This has a F 2A fuse.
⇒ Have your house mains supplies (plugs), fuses and the current consumption of your kiln checked by a
qualified electrician.
7.2. The controller displays an error message
⇒ You will find the relevant explanation in your user's manual for the controller.
7.3. The firing chamber does not heat up
⇒ Check if the lid safety switch is working. The safety switch is probably not working and thus cannot operate
the safety contactor.
⇒ Make sure that the safety switch drops back into the circular hole. If this does not happen, the safety circuit
is interrupted and the kiln cannot heat up.
7.4. The kiln heats up very slowly
⇒ The kiln does not reach the programmed temperatures. The controller displays an error message.
⇒ Check the heating elements for visible damage, e.g. cracks.
8. Additional Information
8.1. Warranty
We guarantee excellent manufacturing and functionality of the kiln and provide a 36-month warranty from date of
invoice.
As well as the heating elements (subject to wear) the following are excluded from the scope of warranty:
• Damage caused by the customer such as broken bricks
• Damage caused by the fired material, e.g. due to temperature limits being exceeded.
• Damage caused by improper transport.
• Damage due to chemical reactions during firing for which the kiln is not intended (such as salt glaze).
• Corrosion caused by aggressive glazes or insufficient ventilation of the firing chamber.
• The manufacturer is not liable for any damage resulting from improper operation and resulting damages.
Please note:
The firebricks of the kiln lining are exposed to significant temperature fluctuations. This may cause hairline cracks in
the firebrick lining. This process is common and does not affect the functionality of the kiln. It cannot therefore be
accepted as a reason for complaint.
