The wash tank heater control system is electrically connected in the circuit to operate on 208-230 Volts. The heat circuit is controlled
by a heat switch (mounted right front panel), water level control (mounted top inside control box), and thermostat (mounted right front
leg underneath). When higher temperature is required, power is applied to the heater element through above controls. Should the wash
tank thermometer read too high or too low, follow checkout below.

CHECKOUT OF HEATER SYSTEM FOR WASH TANK  (Refer to drawing)

NOTE: THE FOLLOWING CHECKOUT SHOULD BE DONE BY A QUALIFIED SERVICE PERSON OR ELECTRICIAN.

1.  Ready the machine for normal dishwashing operation with the wash tank water at proper level.
2.  If temperature is too high, adjust thermostat using thermostat instructions in this manual.
3.  If temperature is too low, adjust thermostat using thermostat instructions in this manual then:

NOTE: ELECTRICAL POWER STILL APPLIED, SO BE CAREFUL. (See instructions in manual for removing control panel front. Refer
to replacement of switch in control panel.)

a.  With circuit breaker, master switch and heat switch on, check power to machine at position 1, terminal board “X” should read

208-230 Volts, if not, check customer’s circuit breaker, if defective, replace.

b.  Wash temperature should be 130°F or less to proceed.

c.  Observe water level control, letter “D”. Turn hat switch on and off several timers. Relay and contact points (inside clear case on

heat water level control) should move back and forth.

AA If water level control relay doesn’t close, (contact points don’t move in “c” above.

1.  Refer to page on Water Level Control’s function and checkout.

BB If water level control relay does close, proceed with heat switch on:

1.  Check voltage at position 1 on terminal board “X”. Voltage is 208-230 Volts.

2.  Check position 2, there should be no voltage. If there is voltage, then adjust thermostat (refer to page on Thermostat Adjusting).

3.  Check position 3, voltage should be 208-230 Volts. If not, check wiring for loose connections or a break.

4.  Temperature should rise slowly, a check with an amprobe would indicate if the element is drawing the correct amperage. Replace

element if defective.

NOTE: A CHECK WITH AN AMP PROBE (POSITION E), IF AVAILABLE, WOULD BE HELPFUL AT THIS POINT.

Clamp probe on a single wire between the thermostat and wash heater element. The element should draw 3 amps. If it does not and
everything above checked out okay, replace the element. This wash element is used to maintain wash water temperature so tempera-
ture rise will be extremely slow - do not depend on this indication.
