SERVICE
These service procedures should only be performed
by a qualified servicer.
WARNING: THE STEAMER AND ITS PARTS ARE
HOT. USE CARE WHEN OPERATING, CLEANING
OR SERVICING THE STEAMER. THE COOKING
COMPARTMENTS CONTAIN LIVE STEAM. STAY
CLEAR WHILE OPENING EACH DOOR.
WARNING: BEFORE SERVICING, DISCONNECT
ELECTRICAL POWER SUPPLY AND PLACE A TAG
AT THE DISCONNECT SWITCH TO INDICATE THAT
YOU ARE WORKING ON THE CIRCUIT. TURN
WATER SUPPLY OFF, RELIEVE LINES OF
PRESSURE AND ALLOW HOT PARTS TO COOL.
COOKING COMPARTMENT
CONTROLS
For access to compartment controls, remove two
screws holding compartment control panel and remove
control panel.
Check for failure of the control circuit in the following
order:
1. Check that electric power is reaching control
circuit through compartment switch when it is
turned ON.
2. On electric heat models with a transformer, check
step down transformer for proper operation.
3. Check limit switch, operated by a tab on the
compartment door, for proper function.
4. Check that timer switches are functioning as
shown on the wiring diagram.
5. Check that timer motor operates when connected
to power.
If problem is found in timer, replace it; do not take
timer apart.
6. Check wiring for damaged insulation (no short
circuit).
7. Check that all connections and terminals are
securely fastened (no open circuits).
8. Check that all connections are made according to
compartment control wiring diagram.
WATER ACCUMULATION ON BOTTOM OF
COMPARTMENT
Water accumulation on the bottom of the cooking
compartment(s) is primarily condensed steam. Failure
to drain out quickly and completely may be due to
clogged debris on the compartment drain screen.
Pull screen straight out and thoroughly clean, then
replace.
Failure to drain completely may also be due to
improperly levelled steamer.
COOKING CYCLE CANNOT BE ACTIVATED
Inspect all wire terminations to ensure they are positive
and secure before assuming any other problem.
When power switch on base generator is ON, set the
timer knob to 2 minutes. Both READY lights should
go off, COOKING lights should come on and steam
should be entering both compartments.
CABINET BASE GENERATOR
ALL GENERATORS
Removal of Scalants From Boiler
It is recommended that the boiler be thoroughly
inspected on at least three-month intervals, and more
frequently in hard water areas and/or for units heavily
used. This inspection consists of an internal
examination and cleaning of the generator shell, an
examination and possible replacement of the descaler,
a check of lime build-up on the level sensing probes,
and a check of all generator controls, including the
pressure switches.
