Electrical-Mechanical Troubleshooting
!WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and discharge capacitor through a 10,000 ohm resistor before attempting to service, unless test procedures require power to be connected. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
!CAUTION
Units covered in this manual are polarized. Reversing polarity of a unit or any of its components will cause damage. To avoid reversing polarity, any wires disconnected or removed during service must be reconnected to the same location. To ensure wires are reconnected to the proper location, tag or otherwise mark the wires before disconnecting or removing.
Will Not Fill
Water Access Valve
Check to determine if the valve is turned on and water is available to the Dishwasher. Check water pressure.
Circuit Breaker/Fuse
Check for tripped breaker or blown fuse. Reset or replace as necessary.
Door Latch
Check door switches for continuity. With door switches engaged, no continuity, replace switch.
Float
Check float position. If in the up position, check for obstruction or disengagement from the Float Switch Arm.
Float Switch
If the float is in the down position, check the switch for continuity. If no continuity, replace the Float Switch.
Water Valve
Check Solenoid for continuity. No continuity, replace Water Valve. Check Inlet Screen for restrictions. Clean screen or replace Water Valve as necessary. (See section 5).
Wiring/Electrical Connections
Check for loose or frayed wire terminal connections. Check for broken wire within harness. Repair or replace as necessary.
Overflows
Water Valve
Check that water continues to flow when electrical power is turned off. If the water continues to flow without electrical power, replace Water Valve.
NOTE: Low water pressure can result in failure of the Water Valve to close properly.
Float
Ensure that the Float isn't stuck in the down position. Check for sediment buildup. Clean and/or replace as necessary.
Float Switch Actuator Lever
Check the actuator lever on the bracket. It must be able to move freely. Repair or replace as necessary. (See section 5).
Float Switch
Check Float Switch for continuity with the Float in the up position. If continuity is present and Float moves up and down freely, replace Float Switch.
POOR WATER CIRCULATION
Water Level - Too Low
Normal water fill should be at level depicted by arrows.
Pump Assembly
Check assembly for obstructions or restricted movement of parts. Repair and/or replace parts as necessary.
