Temperature is stille not increas-
ing
Check if there is power to the heaters.
If this is OK and the temperature is set correctly, it is
a heater that is defect.
If there is power to the heating ele-
ment and temperature is set correctly, the following
may be faulty:
• solid state relay (item 88-00231)
• main switch (item 84-00068)
• power supply * (item 88-00184)
• Print board (item 88-00560)
Solid state relay can be checked by measuring that it
receives 24V from power supply. If it does, there must
be forward current at
the 230V terminal. Remember that the heater must be
connected, since otherwise the SSR quirks.
Main switch is checked by measuring the forward cur-
rent.
The machine is heating over heat-
ing
Check whether the program
is correct. Check that solid state relay switches off.
If it does not switch off, it can be caused by a
faulty heater.
Check if the heating sensor is defective.
Smoke is coming out form the
machine
Check that the exhaust blower is running and that
exhaust system is not blocked.
If blower needs to be changed, always change the
condenser as well.
Hamburger is not cooked proper-
ly
Check that
• temperature is set correctly on both displays.
• The distance between the pans are set correct-
ly (must match the thickness of the hamburger)
During frying, the temperature will fluctuate between
approx. 220
C and 260
C. If the tempera-
ture fluctuates more,
check that the sensors are correctly located in the grill
pans.
Hamburgers are still not cooked
properly, and lower roast plate
opens periodically.
The lower axle does not run freely in the bearings:
Change bearings, or realign the bearing house,
this must be done from the left side of the machine.
Hamburger is only roasted on
one side
Check the angle between the roasting systems.
This can be adjusted in the left side of
the machine using the socket screws to align the bot-
tom roasting system. The distance between the upper
and lower working surface must be equal on both
sides.
Note. This must be done when the machine is hot
