Leaking  “LE” Code 

Moisture 

creates resistance between the pins. 

ALWAYS

 

clean the area below the pins after troubleshooting.

 

Check Pump Ass’y 

for proper twist lock.

 

Condensation 

may form on the tray from uninsulated    

outside walls or large hole in the floor to a cold basement. 

Check Drain Hose 

for cut or small hole. 

Check all components 

mounted to the sump for any   

leakage.

 

Cavitation “surging” In Prewash

 

 

During the first fill (pre-wash), the water level supplied to circulation pump drops, while water is distributed through the 
 spray arms and tower assembly (resulting in cavitation.) During the next fill, voids in these areas are already filled with 
 water and level is sufficient (no cavitation.)  Between uses, water in the spray arms and tower assembly completely 
 bleed out, leaving them empty. At the beginning of next use, the D/W will pump for 45 seconds before filling and  
 cavitation will occur during the prewash. Inform the customer that the cavitation “SOUND” is part of normal operation. 

 

If Cavitation Occurs During All Cycles or is Intermittent

 

Make sure drain hose has not been moved from the side of cavity during Installation, verify proper “loop”.

 

Check for proper fill (valve and flow meter) in t1 test mode.

 

Water lost in distribution, such as inside cups, glasses, bowls that flip over can cause a drop in water supplying the wash   
motor and can cause cavitation sound during any cycle.

 

Detergent Door Not Opening

 

1. Never overfill the dispenser compartment with powder or liquid, only go below or up to fill line.

 

2. If there is residue around the dispenser door area.  Previously undispensed, partially dispensed, or door stuck close  
issue) clean it with mild soap & water.  The residue can foul the mating latch.

 

3. If the customer uses “tablets” or some self contained type of soap tab, make sure it is fully seated and the door does  
not ‘sandwich’ it shut.

 

4. Make sure that in the rack nearest to the dispenser door when the door is shut, is not obstructing the opening of the 
dispenser with some protruding utensil. 

                           

  

 

Testing The Detergent Door and Dispenser 

 

1. Disconnect wires from disp. & close detergent door.

 

2. Connect Fused cheater cord and apply 120vac

 

3. In approximately 40 seconds the wax motor will open the door.

 

4. Remove power, allow wax motor to return.

 

5. Restore power to wax motor, in approximately 40 seconds the rinse aid will be activated. Remove power.

 

6. Close detergent door to repeat test
