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 Checking 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. When LED is not illuminated, then
check that the following conditions are true:
Page 31
25
BASIC SERVICE
TROUBLESHOOTING TIMER CIRCUIT BOARD (cont.)
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 it is not, replace it.
Red ‘Power’ LED
• Verify that the red ‘power’ LED is illuminated.
If it is not, and the previous 2 conditions are true, then the board is bad and should be replaced.
1.3 Testing 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 Switch (if installed).
Perform the following steps to test a board input:
1. Set the voltmeter to measure DC volts.
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, not used on D-HBT or D-H1T).
• T8, marked “DOOR SW” (for the door safety switch).
• T9, marked “FLOAT SW” (for the float switch).
• T10, marked “EXT. WASH” (for the extended wash switch, not tested on D-HBT or D-H1T).
4. Check the results on the voltmeter:
• If switch is opened – the meter should read between 4.7 to 5.3 DC volts.
• If the switch is closed – the meter should read between 0 to 1 DC volts.

1.4 Testing 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) (doors must be closed before testing).
• T4, marked “RINSE OUTPUT” (for the rinse cycle) (doors must be closed before testing).
• 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.

Float Switch
Troubleshooting Chart
Models D-HBT and D-H1T use a float switch and circuit board to
control tank fill and tank heat.
For Model D-HBT 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 below (Fig. 15) for a quick guide to evaluating float switch problems.

Motor Connections —
1. Models D-HBT and D-H1T 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 Fig. 17 for the proper wiring of the pump motor for single and three phase voltages.

DRAIN VALVE/TIMER CIRCUIT
Models D-HBT and D-H1T use 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 position, 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.
