How to enter service / parameter mode
- Press the centre of the Cone key to open the Manager’s Menu.
- At ENTER ACCESS CODE, set each digit with the arrow keys and SEL (the code is in the manual).
- Fault Description shows current faults; Fault History holds the last 100; Lockout History holds the last 100 locks and heat cycle failures.
Notes
- Pressing SEL on the Fault Description screen clears faults that have been fixed.
- A soft lock can be cleared by brush-cleaning; a hard lock needs a full brush-clean before serving.
