Common questions about manuals, registration, and support for this brand.
Error code E-4 indicates "CPU TOO HOT". This means the control board is overheating. Remove heat from the fryer and allow the front panel to cool down; the controls should return to normal operation. If the error persists, contact service.
If the filter motor overheats and won't run, turn the power switch OFF to avoid burns. Wait about 5 minutes for the motor to cool. Locate the manual reset button on the front of the motor (accessible via the side panel) and press it to reset. A screwdriver may be helpful.

Daily cleaning is recommended to maintain equipment performance and food quality. Using products like Henny Penny Prime Cleaner packets can help remove tough residues without the need for a vinegar rinse.
Foaming can be caused by the lack of oil stabilizers, degraded oil, or cooking products with excessive ice crystals. Refer to the boil-over chart in your operator's manual and ensure you are using proper frying procedures.
