sometimes necessary to re-adjust the temperature at start -up.
A.2.5.2 Locate the temperature control board (P/N DE9-96). Use the control panel layout drawing
located in Section 3, Electrical Schematic and Replacement Parts.
A. 2.5.3 Adjust the tank temperature to the desired temperature by turning the potentiometer located on
the temperature control board. An arrow on the potentiometer indicates increase.
A. 2.5.4 If the temperature does not change refer to section A.2.6, Troubleshooting Tank Temperatures.
A.2.6 Troubleshooting Tank Temperatures
A.2.6.1 Electric Heat
A.2.6.1.1 If temperature cannot be adjusted per section A.2.5 check the temperature control
board (P/N DE9-96) proper operation. If the temperature control board is faulty,
replace.
A.2.6.1.2 Verify tank heat contactor is working correctly. If not, replace.
A.2.6.1.3 Verify all immersion heaters are working properly and not limed. If not, replace.
A.2.6.2 Steam Heat
A.2.6.2.1 See Section A.2.6.1.1.
A.2.6.2.2 Verify steam pressure per machine specifications.
A.2.6.2.3 Verify steam trap is not clogged. If so, replace.
A.2.6.3 Gas Heat - Infra-red Gas Burner Sequence of Operation
A.2.6.3.1 See Section A.2.6.1.1.
A.2.6.3.2 Verify gas supply.
A.2.6.3.3 Temperature control board calls for heat, a relay is energized and the draft blower
starts.
A.2.6.3.4 When the blower comes up to speed, a centrifugal switch integral with the motor
illuminates the gas burner-airflow light and energizes the Hot Surface Ignition (HSI)
module.

Part 3, Section A
A.2.6.3.4.1 The HSI institutes a purge period followed by a trial for ignition during
which the ignitor element heats up. The gas valve is opened.
A.2.6.3.4.2 After ignition, the element becomes a flame sensor. The system
continues to monitor flame presence.
A.2.6.3.4.3 If the flame fails during operation, the gas valve will close. The HSI
module will purge the gas line then try to re-light the burner. The gas
burner-flame light will be out. If the re-trial fails, the gas valve will close
and the system will lock-out until the dishmachine main power toggle
switch is cycled off then on.
A.2.6.3.5 When the temperature control board reached the high limit the system will shut-down
as normal. The gas system lights will be off. If the temperature drops the system will
re-start.
A.2.6.3.6 Burner Flame Adjustment
A.2.6.3.6.1 After a short warm-up period, the infra-red burner will glow with a uniform
orange/red color. There are no individual flames. There is an air inlet
shutter to adjust the flame for maximum efficiency.
A.2.6.3.6.2.1 A soft blue flame indicates excess air, bright orange
indicate lack of air. A view port is provided on the burner
and a window on the burner assmebly cover to view the
flame. A combustion analyzer is required for correct
adjustment.
A.2.7 Motor Overloads
A.2.7.1 All motors used on Insinger Machines are provided with motor overloads. Motor overloads are
adjusted when the machines are factory tested. Should it be necessary to adjust the motor
overloads in the field first verify the motor current draw for the voltage the machine is using.
A.2.7.2 Using the Control Panel Component Layout Dwg.located in Section 3 to identify the overload
adjust by turning the dial to the appropriate AMP draw.

A.2.8 Level System
A.2.8.1 The level control system consists of one overfill timer (P/N DE7-33) and one level float (P/N
DE5-60) per tank (two level floats for electrically heated machines ).
A.2.8.2 When the system is powered-up, the tank(s) will begin to fill (assuming no water is in the
tanks) .
A.2.8.3 Once the upper level float (for electrically heated machines) or the level float (for other tank
heat) is actuated, the overfill timer begins to time-out and continues the filling process until the
tank(s) is full.
The overfill timer MUST be adjusted during initial machine start-
Adjustment depends on water fill pressure. The water level MUST
be 1/2" below the lip of the overflow tube. Adjust by increasing or
Dirty level floats will cause the tank heat
A.2.9 Final Rinse Actuator
A.2.9.1 The final rinse is actuated by a lever located on the rear wall of the dishwasher near the exit
end. When a rack depresses it a switch is closed and a solenoid energized.
A.2.9.2 The activation of the lever also resets the Energy Saver Timer (P/N DE7-28). The timer will
then start counting from 0. The timer is adjustable between 0 and 300 seconds (5 minutes).

In order to insure the proper operation of your INSINGER dishwasher, it is
necessary that the LIQUID LEVEL FLOAT be wiped free of any residue and/or moisture at each
cleaning. This should be done, preferably, after each use of the machine, or, at a
minimum, once each day.
The LIQUID LEVEL FLOAT is located below the scrap screens in those tanks which
contain water heating devices (coils, steam injectors, or electric immersion heaters) and
pump inlet strainers. They are usually located, in rackless and rack conveyor style
machines, on the inside tank wall, at approximately water level, opposite and parallel to
the inspection doors. In the door, stationary rack, type machines, the LIQUID LEVEL
FLOAT may be found beneath the scrap screen.
Below is a depiction of the LIQUID LEVEL FLOAT and the surfaces which must be wiped
clean.

switch after the temperature drops below 200°F. This can be done without removing the burner box cover
through a hole above the indicator lights.
Hot Surface Ignition Module -
24 VAC, 30 second prepurge, 4 second heat-up time, 4 second trial for ignition. Loss of flame will result in
one re-try for ignition. This unit cannot be repaired - it must be replaced. Flame current .75 micro amp minimum.
Gas Valve -
This valve is equipped with a redundant solenoid valve that controls gas flow to the pilot and main burners,
a relay operated main valve that controls gas flow to the main burner, a pressure regulator to maintain a
constant outlet pressure, and a two-position gas cock knob for manual gas shut -off. Both redundant and main
valves open together due to the jumper wire installed between terminals M-1 and P-3.
The gas outlet pressure is stamped on a metal nameplate inside the burner box. This should be checked
using a manometer at the pressure tap on the outlet of the valve. Remove 1/8" pipe plug with an allen wrench
(not brass hex fitting) to install test fitting.
The gas supply to the valve can be checked using a manometer at the pressure tap on the inlet of the
valve. Shut off gas downstream before removing 1/8" pipe plug to install test fitting.
Hot Surface. Element (Ignitor) -
This consists of a silicon carbide heater blade cemented into a ceramic holder with a metal mounting plate
mechanically attached. The ceramic extends 3/4" past the mounting plate into the burner. The wide surface of
the blade must face the burner surface.
To check operation, shut off gas supply. The glow of
the igniter during the heat -up and trial-for-ignition
Hot Surface Element (Ignitor) continued -
periods can be seen through the viewport (look up from ground level) . If no glow can be seen, a
cracked blade or bad blade to wire joint is possible. Disconnect wire leads and measure resistance at
room temperature (1 to 6 ohms).
Main Orifice -
This is installed inside a special holder fitting at the 3/8" NPT boss on the burner elbow. The
orifice diameter is stamped on a metal nameplate inside the burner box and on. the orifice itself.
Infra-Red Burner -
This consists of a ceramic cylinder attached to a steel elbow. Burner operation can be
monitored through the viewport and the window in the burner box cover. Upon starting, a blue flame
is visible changing to a dull orange glow over the complete burner surface after warm-up. Continued
operation with a blue flame indicates burner out of adjustment. Proper adjustment of the air shutter
should be made using a combustion analyzer.
Excess Air - burner may be difficult or impossible to light; will not generate sufficient heat.
Insufficient Air - burner may produce hazardous levels of carbon monoxide gas .
