Booster Heater/Wash Tank Heater Interlock Circuit Operation - UH130B, UH230B, UH330B

Booster Heater/Wash Tank Heater Interlock Circuit Operation

 

For Models UH130B, UH230B 

The booster heater/wash tank heater interlock circuit removes  

power from the wash tank heater whenever the booster heater contactor energizes.   

The illustration below shows how the booster heater contactor is wired.  
The booster heater contactor is located on the center of the base behind the lower front access 

panel.

Interlock Circuit Operation

1.  The dishwasher fills with water when the main power switch on the dishwasher is turned on. 

The booster heater thermistor calls for heat which energizes the booster heater contactor.  

2.  The auxiliary contact on the top of the contactor opens and removes power from the  

wash tank heater.

3.  When the booster heater thermister is satisfied, the booster heater contactor de-energizes  

and the auxiliary contacts close applying power to the wash tank heater.  

4.  This operation is repeated whenever the booster thermistor calls for heat.
