Maintenance
The Groen Convection Combo™ is designed for
minimum maintenance. Certain parts may need
replacement after prolonged use. If there is a need
for service, only Groen personnel or authorized
Groen representatives should perform the work.
Always
supply water with a low mineral content that
meets the standards outlined in the
Water
Conditioning
section of this manual.
If steam or condensate is seen leaking from around
the door, take the following steps:
1.
Check the door gasket. Replace it if it is cracked
or split.
2.
Inspect the cooking chamber drain to be sure it is
not blocked.
3.
Adjust the latch pin as follows:
a.
Loosen the lock nut at the base of the latch
pin, and turn the latch pin ¼ turn clockwise.
Re-tighten the lock nut.
b.
After adjustment, run the unit in the Steam
Mode to test for further steam leaks.
c.
If leakage continues, repeat the adjustment.
d.
Continue adjusting the pin clockwise until the
door fits tightly enough to prevent leaks.
Troubleshooting
A.
Pilot Burner
Remember that the front control panel will not
operate until the pilot switch has been activated
and the pilot burner flame has been ignited
(green light is on). For details, see Initial Start-
Up on page 11. If the procedure described in
Initial Start-Up has been followed and the pilot
burner still does not light, contact your authorized
Groen Service Agency.
B. Resetting the Solid State Controls
(If problems persist call an authorized Groen
Service Agency)
If the controls stop responding to normal
commands, or the unit is behaving oddly, reset
the controls using the following procedure:
1.
Switch off the power by pressing the
ON
touch pad.
2.
While pressing the
COMBO
touch pad,
switch the power back on. If no errors are
present the unit will beep and show four
zeroes in the timer display. If there are
errors, the unit will
not
beep, but will display
Service Codes, both in the timer and cook
temperature displays.
Note the Service
Codes
. Press
CLEAR
to exit the Service
Mode and refer to the following explanation
of service messages.
C. Service Messages
There are two types of service message:
1.
Non-critical error: signaled by three quick
beeps. The
SERVICE
light comes on for 15
seconds and then goes out.
2.
Critical error: signaled by a continuous five
second beep. The
SERVICE
comes on and
stays on.
If there is a non-critical error you may continue to
operate the unit. When possible, check the
Service Code. Turn off the unit by pressing the
ON
touch pad. While pressing the
COMBO
touch pad, switch the power back on. Note the
numbers and refer to the Troubleshooting Guide
which follows. Press
CLEAR
to exit the Service
Mode.
If there is a critical error, the unit will not operate
in its present mode, but it may operate in another
mode. Check the Service Code as instructed
above, then call your authorized Groen Service
Agency.
If the problem continues after you follow the
instructions in the Troubleshooting Guide, call
your authorized Groen Service Agency.
