Fuses

—

Refer to Fig. 10. There are two fuse blocks, located in the center of the main control cabinet. The (A) fuses protect the main control transformer. The (B) fuses protect the wash tank heater circuit. Fuses are marked FU on the 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 Fig. 11.

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 Fig. 11 is positioned to adjust the motor overload AMP setting. Read the full load amps (FLA) motor amps on the motor nameplate. Adjust the overload dial to 125% of the nameplate FLA or the maximum setting.

FILL TIMER

Models D-HB, D-H1, and D-LF use a float switch and fill timer 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, fill timer runs for a minimum of 90 seconds to fill the tank.

2. The float switch ball rises; its normally open contacts close. The fill circuit times out; the fill 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 timer runs for a minimum of 90 seconds to refill the tank.

4. If the tank is not full of water at the end of the 90-second fill timer cycle, then the fill timer will cycle again. When the float switch is satisfied, the fill timer stops after completing its 90-sec. cycle.

5. Refer to the float switch troubleshooting chart below (Fig.17) for a quick guide to evaluating float switch problems.
