5.3 Component Repair and Replacement (Cont.)
5.3.10 Final Rinse (Steam) Thermostat Adjustment and Replacement (cont)
NOTE:
The final rinse control thermostat serves two functions-first as the final rinse control thermo-
stat and second as the final rinse low temperature cutoff thermostat. When you adjust the
final rinse control thermostat, you are also adjusting the final rinse low temperature cutoff
thermostat.
To replace the final rinse/ cutoff thermostat: Turn off the water and steam supplies to the booster.
Place a rack in the dishwasher to operate the final rinse and bleed off any water pressure from the line.
Turn power off to the dishwasher at the dishwasher control. Remove the protective cap from the thermo-
stat body. Note the location of the wires and disconnect. Disconnect the conduit. Remove the thermostat
from the booster piping. Install the replacement as shown in the diagram below. Follow instructions as
listed on Part 8: Service Bulletins on Page 91. Return the dishwasher to normal operation and perform
the adjustment procedures described on the previous page.

appearance to the 3/4" water valves, (See 5.3.4). The steam
booster uses a 3/4" steam solenoid valve on the inlet of the booster
steam supply line, (See picture to the right)
