2. To determine if elements are working:
a. There is an insulated movable bar on the heater relay across the top of the
two contacts. With an insulated probe, depress the bar and observe the rinse
thermometer; the temperature should rise noticeably in a minute or two. If it
moves VERY slowly, it would indicate that one element is defective. If it moves
consistently higher at a steady rate, the elements are working properly.
b. Check voltage at position 4. There should be 208-230 Volts. If not, check wiring.
Clamp probe on single wire between heater relay and heater elements. The elements
together on a single phase should draw 30 amps; one element will draw only 10 amps.
Replace element if found inoperative.
3. If relay is closed, but elements do not heat, use same general methods used in step
2 above for checkout.
