Troubleshooting
E:06 Error message
After turning the heating 'On', note the time taken to display E:06 on the LCD display. This
will assist in diagnosing the cause of the problem.
Please note that there must be full power heating, and both the blue lights should be
flashing. To ensure full heating power, it is recommended that a minimum of 500ml of cold
water is in the bowl, a stirring tool is fitted and the temperature control is set to 100ºC
minimum.
