temperature sensor. If A5 is displayed, replace  
temperature sensor.  
Faulty high limit stat (Tl)  
Reset thermostat by depressing red button. Replace if  
necessary. Make sure heater relay (Cc) is working  
properly (not stuck in or out) and Tc thermostat is cutting  
off below 195°F  
Dishwasher RUNS.  
RINSE WATER NOT  
REACHING MINIMUM  
TEMPERATURE OF 180°F  
Faulty heater relay (Cc)  
Faulty Boiler element (Rc)  
Verify voltage at heater relay coil (A1, A2), solenoid  
closes when receiving voltage. If not, replace heater relay  
(Cc).  
Ohm out element check for continuity; if open, replace
