CAUTION:

Care should be taken when lifting the machine to prevent damage.

1. Immediately after unpacking the machine, inspect for any shipping damage. If damage
is found, save the packing material and contact the carrier immediately.

2. Remove the dishwasher from the skid. Adjust the feet if required, then move the
machine to its permanent location.

3. Level the machine (if required) by placing a level on the top of machine and adjusting
the feet. Level the machine front-to-back and side-to-side.

4. Remove the two dishracks and pressure gauge from the interior of the machine. Install
the pressure gauge in the upper fill piping of the dishwasher in the petcock provided.

NOTE:

The installation of your machine must meet local health codes.

Changing from Straight-through to Corner Operation

Your door-type dishwasher was specified to the factory as a straight-through conf iguration
or corner configuration. Your machine can be converted from straight-through to corner or
from corner to straight-through. Contact factory for instructions on changing the operation
of your dishwasher.

Electrical Connections

WARNING:

Electrical and grounding connections must comply with the National Electrical Code
and/or Local Electrical Codes.

WARNING:

When working on the dishwasher, disconnect the electric service and place a tag at the
disconnect switch to indicate work is being done on that circuit.

1. A qualified electrician must compare the electrical power supply with the machine
electrical specifications stamped on the MACHINE ELECTRICAL CONNECTION
PLATE located inside the top mounted control cabinet before connecting to the
incoming service at a fused disconnect switch.

2. Motor rotation was set at the factory. Check the rotation of the motor shaft (CW when
viewed from rear of motor). For three phase machines, reversing the motor direction is
done in the control cabinet by reversing the wires L1 and L2 on the disconnect side of

Electrical Connections (cont’d)

the main electrical connection block. For single phase machines, motor rotation is
changed at the motor connection plate on the rear of the single phase motor.

3. A knock-out is provided at the rear of the top mounted control cabinet for the electrical
service connection. A single source electrical connection has been provided. A fused
disconnect switch or circuit breaker (supplied by others) is required to protect each
power supply circuit.

Plumbing Connections

CAUTION:

Plumbing connections must comply with local sanitary and plumbing codes.

electrical schematic. Booster heater circuits
(D-HB only) are not fused.

To Replace a fuse:

Turn the dishwasher main power switch off.
Disconnect power to the machine at the main
service disconnect switch.
Replace the fuse. If the fuse blows again,
DO NOT INCREASE THE FUSE SIZE.
DETERMINE THE CAUSE OF THE OVERLOAD.

Motor Overloads

The wash pump motor has an overload to protect it from line voltage electrical overloads.
The overload disconnects 120VAC power to the motor contactor coil.

Refer to Figure 10.

Note the Switch Lever on the Overload.

If the switch lever is off with the “0” showing then the overload has tripped.

To Reset the Motor Overload:

Flip the overload switch to the On position. A “1” should be
visible on the switch lever.

To Replace a Motor Overload:

Disconnect the wires to the overload. Release the mounting
catch on the front side of the overload. Push forward and lift
out. Snap the new overload into place and reconnect the wires.

To adjust the overload setting:

The screwdriver in Figure 10 is positioned to adjust the
motor overload AMP setting. Read the full load amps
(FLA) motor amps on the motor nameplate. Turn setting
to match nameplate.

Troubleshooting Timer Circuit Board

1.1 Introduction

The following procedures are for determining whether or not the timer circuit board itself
is faulty.

In this part —

• Checking the general condition of the circuit board.

• Testing inputs.

• Testing outputs.

Special Tools —

• A voltmeter capable of reading DC and AC volts.

1.2 Chec

king General Condition

Before testing the inputs and outputs, you should first check that the board is receiving power.

Turn on the power switch to the unit (do not start the unit, just turn ON power to the unit). If red
“POWER” LED on board is illuminated, go directly to “1.3 Testing Board Inputs.” When LED
is not illuminated, then check that the following conditions are true:

Power Terminals

• Verify that the board is receiving power of 120 VAC at the terminals:
— T2, marked “H” (AC Hot).
— T1, marked “N” (AC Neutral).

If either of these terminals is not receiving 120 VAC, then there is a problem elsewhere with
the unit not receiving power.

The Fuse (F1)

• Verify that the circuit board fuse (F1) is good.

If not replace it.

Red “POWER” LED

• Verify that the red “POWER” LED is illuminated.

If it is not, and the previous two conditions are true, then the board is bad and should
be replaced.

1.3 T

esting Board Inputs

After you have verified that the circuit board is receiving power (as
explained above), then test the board inputs. There are 4 board inputs:

• Start Switch • Door Safety Switch

• Float Switch • Extended Wash (not used on this Model)

Perform the following steps to test a board input:

1. Set the voltmeter to measure DC volts.

19

BASIC SERVICE

2. Place the NEGATIVE (Black) test probe on the “HOT” terminal:

• T2, marked “H”.

3. Place the POSITIVE (Red) test probe on the input terminal to be tested:

• T7, marked “START SW” (for the Start Switch).

• T8, marked “DOOR SW” (for the Door Safety Switch).

• T9, marked “FLOAT SW” (for the Float Switch).

4. Check the results on the voltmeter:

• If switch is opened – the meter should read between 4.7 to 5.3 DC volts.

• If switch is closed – the meter should read between 0 to 1 DC volts.

1.4 T

esting Board Outputs

After you have verified that the circuit board is receiving power (as explained above), then test
the board outputs. There are 4 board outputs:

• Wash Cycle • Rinse Cycle

• Heaters • In-Cycle Lamp

Perform the following steps to test a board output:

1. Set the voltmeter to measure AC volts.

2. Place the NEGATIVE (Black) test probe on the “NEUTRAL” terminal:

• T1, marked “N”.

3. Place the POSITIVE (Red) test probe on the output terminal to be tested:

• T3, marked “WASH OUTPUT” (for the Wash Cycle).

• T4, marked “RINSE OUTPUT” (for the Rinse Cycle).

• T5, marked “HEATERS OUTPUT” (for the Water Heater).

• T6, marked “LAMP OUTPUT” (for the In-Cycle Lamp indicator).

4. Check the results on the voltmeter for the terminal you are testing:

• For T3 – the meter should read 120 VAC whenever the unit is in cycle and the
“WASH” LED is illuminated on the circuit board.

• For T4 – the meter should read 120 VAC whenever the unit is in a fill or rinse mode and
the corresponding “FILL” or “RINSE” LED is illuminated on the circuit board.

• For T5 – the meter should read 120 VAC whenever the power switch is on and the wash
tank is full (i.e., the float switch is up).

• For T6 – the meter should read 120 VAC whenever the machine is in cycle.

BASIC SERVICE

Models D-HB, D-H1, and D-LF use a float switch and circuit
board to control tank fill and tank heat.

For Model D-HB only, the built-in booster heat circuit is also
controlled by the float switch.

Operation:

1. When dishwasher main power switch is turned on (wash
tank empty), the drain valve closes allowing cycle time to
run for a minimum of 110 seconds to fill the tank.

2. The float switch ball rises; its normally open contacts close.
The fill circuit times out; the f ill solenoid de-energizes, and
the tank heat and booster heat energize.

3. If water level drops below the float level, the float switch
ball moves down; heat de-energizes. The fill solenoid
energizes and the fill cycle runs for a minimum of 110
seconds to refill the tank.

4. If the tank is not full of water at the end of the 110-second fill cycle , then the machine
will cycle again. When the float switch is satisfied, the fill cycle stops after completing
its 110-second cycle.

5. Refer to the float switch troubleshooting chart (Fig.13) below, for a quick guide to
evaluating float switch problems.

Motor Connections

1. Models D-HB, D-H1, and D-LF are available in either single phase or 3 phase voltages.

2. Motor rotation was set at the factory. For three phase machines, reversing the motor
direction is done in the control cabinet by reversing the wires L1 and L2 on the
disconnect side of the main electrical connection block. For single phase machines,
motor rotation is changed at the motor connection plate on the rear of the single phase
motor (if necessary).

Refer to Figure 14 for the proper wiring of the pump motor for single and three phase voltages.

DRAIN TIMER/VALVE CIRCUIT

Models D-HB, D-H1, and D-LF uses a drain circuit consisting of a 3cr relay, 10 minute timer,
and a drain valve.

OPERATION:

1) When the power switch is pushed to the OFF posistion, the 3CR relay coil is then
energized, closing the 3CR contacts.

2) Drain timer now is powered from the 3CR relay, which opens the drain valve
for ten (10) minutes.

3) When the timer times out (10 minutes), the drain valve closes and machine has
completed it's drain cycle.

NOTE: Flip the power switch on the machine to ON then OFF position to open the drain
for an additional drain cycle. Repeat this step as necessary.
