CAUSE 1 Machine using more water than normal by rinse running throughout wash cycle caused by faulty rinse microswitch in timer 2 Incoming water supply not hot enough 3 Heater switch faulty 4 Setting on thermostat con trol has been moved from original factory setting 5 Thermostat faulty 6 Heater faulty 7 Contactor faulty 8 Thermometer faulty 1 Spray arms are not moving freely or ends bent down ward 1 Timer defective and stopped in timed cycle 1 Circuit breaker tripped 35 SOLUTION 1 If this trouble occurs it should be determined that the rinse is running during the wash cycle by in specting the rinse sole noid and by disconnecting the wash motor lead at the terminal board on the control panel See instruc tion page on timer 2 Provide adequate supply of hot water see specifica tions sheet 3 Check heater switch 4 Try new setting Move the thermostat control clock wise for higher setting 5 Check thermostat see instruction page 6 Check heater see instruction page 7 Check contactor see instruc tion page 8 Remove thermometer and check in hot water against an accurate thermometer 1 See instruction page on preventive maintenance pull upward on ends of longest wash spray arms 72 1 Move start switch to middle position start switch is three position UP Start CENTER Off DOWN Start See instruction page on timer 1 Reset circuit breaker
3. FORCE DOWN amp IN WITH FINGERS FIG 4 WATER LEVEL CONTROL s FOR RINSE TANK P N 0205000 FUNCTION The Water Level Control device utilized on power rinse PRB models only automatically maintains the water level in the rinse tank The rinse tank water level control is energized by the master switch The control is designed to sense when the proper water level is maintained At this time the relay in the clear plastic case will activate opening the normally closed circuit to the solenoid which stops the water flow to the rinse tank When water is removed from the tank by the rinse pump the sensing probe will alert the water level control by signal to deactivate and return the contact points on relay in clear plastic case to the normally closed position allowing power to be reapplied to the solenoid valve Water will again flow into rinse tank until proper level is reached and maintained CHECKOUT NOTE ALL ELECTRICAL CHECKS SHOULD BE MADE BY QUALIFIED SERVICE PERSONNEL OR ELECTRICIAN If one of the following problems exist this control should be checked out as shown below 1 Water to rinse tank runs continually with the master switch on 2 Water does not flow into rinse tank when required PROCEED WITH CHECKOUTS 1 Remove power source to machine by moving breaker to off position 2 Remove 4 screws holding control pane to control box and fasten to control box on right side using 2 screws wi
4. The Rinse Tank Heater System is electrically connected in the circuit so that it is dependent upon the dishwasher being properly filled with and maintaining a safe water level The automatic fill system therefore should operate properly before the heat system can be engaged The circuit is controlled by a heat switch mounted on the front control panel a thermostat mounted behind the lower front panel a water level control mounted in the control box and a heater relay mounted in the control box with the coil being activated by the thermostat INDICATORS OF POSSIBLE MALFUNCTION Once the machine has been filled and the heat system engaged the heat circuit should operate by merely turning on the heat switch Should the rinse tank heat be it either too high too low or no indication of temperature at all the following checkouts should be made CHECKOUT OF HEATER SYSTEM FOR RINSE TANK Refer to drawing figure 1 NOTE THE FOLLOWING CHECKOUTS SHOULD BE DONE BY A QUALIFIED SERVICE PERSON OR ELECTRICIAN 1 If temperature is too high adjust thermostat using thermostat instructions in this manual 2 If temperature is too low adjust thermostat as above then a Turn off power to machine by tripping customer circuit breaker to off position Turn off machine circuit breaker located on right side of control box b Remove lower cover plate on control box held by single screw c Make sure rinse temperature is below 1

6. OUTSIDE NUT 5 BAT OR TOGGLE HANDLE THERMOSTAT ADJUSTMENT The thermostat can be adjusted by turning screw 1 see picture on the thermostat control box cover Remember the present setting in case the problems are elsewhere in the control circuit A CW rotation is used to obtain a lower temperature setting and a CCW rotation is used to obtain a higher temperature setting A 1 8 turn of screw 1 changes the temperature approximately 15 F If screw 1 is turned all the way to its stop in either direction adjust screw 2 as follows DO NOT TOUCH THE SCREW SEALED WITH RED PAINT When adjusting screw 2 power should be disconnected during adjustment Set screw 1 so that it can be turned equal distances in either direction then if screw 1 stopped while turning in CW direction turn screw 2 in CW direction slowly and only 1 8 of a turn or less per complete cycle of the unit if screw 1 stopped while turning in CCW direction turn screw 2 in CCW direction slowly and only 1 8 of a turn or less per complete cycle of the unit Three fourth s of a turn will bring the thermostat to approximately the same setting obtained where screw 1 stopped Check the present temperature setting before attempting any further adjustments Use screw 1 for any further adjustments NOTE Making large moves in adjusting may cause misalignment thus increasing the chances that further adjustment cannot be made and the thermostat will have to be
