Voltage Measurement Safety Information

When performing live voltage measurements, you must do the following: I Verify the controls are in the off position so that the appliance does not start when energized. I Allow enough space to perform the voltage measurements without obstructions. I Keep other people a safe distance away from the appliance to prevent potential injury. I Always use the proper testing equipment. I After voltage measurements, always disconnect power before servicing.

This can be done with a screwdriver or similar tool from either the top or bottom side of the control. Rast Connector Pinout 2. Connector Brace Removal: Pin 1 Locate the 3 brace locking tabs as shown. Push each tab in the direction required while applying light downward rotational force Pin 1 on the brace. It is easiest to unlock one tab at a time, working from one end of the brace to the other.

3. Once all 3 tabs are unlocked, pivot the brace to allow removal and gain access to the wiring harness connectors and control for required servicing.

4. Connector Brace Reattachment: Attach the brace hinge hooks into holes in the hinge tabs on control housing base. Pivot brace until all 3 locking tabs snap into housing lid. Make sure the harness wires lay flat and are not pinched.

5. Connector Box Reattachment: Position the connector box over P4 and P5 connectors, insert the retainer tabs into brace mounting holes, and snap box onto control housing lid. Make sure box is sitting flush against both the brace and housing and harness wires are flat and not pinched.

Meter Check of Loads and Fuses

Fuse Service Check: Fuse Resistance Check:

F601 = Small triac load fuse Unplug dishwasher or disconnect power. F600 = Wash pump motor fuse Measure resistance of fuses F600 and F601. Check operation of loads during Service Diagnostics cycle. a. Disconnect wash pump motor wiring jumper P5 from the control board. b. Using a resistance meter, measure the resistance between control board If any of the triac loads work (fill, dispenser, drain), F601 fuse is OK. connection pins P5-2 and P6-3. If all triac loads fail to work, F601 fuse could be open. See “Control Pinout” diagram.

If wash pump motor runs, F600 is OK. If resistance is <3 W, both fuses are OK. If wash pump motor does not run, F600 fuse could be open. If either If resistance is >3 W, replace control. fuse could be open, See “Fuse Resistance Check.” What To Do If Fuse Open:

Inspect and check resistance of all loads on fuses. If any loads are open, shorted, or have evidence of overheating or pinched wires, replace loads and/or repair wires.
