COMPONENT OPERATION AND REPAIR

SAFETY PRECATIONS

Always turn off the electric power supply before servicing any electrical

component,makingohmmeterchecks,or replacinganyparts.,

All voltage checks should be made with a voltmeter having a full scale range of

130 volts or higher.

After service is completed, be sure all safety-grounding circuits are complete, a!t

electrical connections are secure, and all access panels are in place.

TIMER

With the timer, user selects the various cleaning cycles of the dishwasher. The

timer controls all the electrical functions of the dishwasher in all stages of each

cycle.. All functions can be traced on the chart.. Diagram provided in this service

manual..

If the timer is suspected of faulty operation, reference timer chart and electrical

schematic diagram and proceed as follows:

1. Index the timer to the first increment of the normal cycle, which is a drain

period.

2. If the pump motor fails to operate during the first cycle increment, check for

power at the pump motor connector block, if there is no power check the door

latch switch, if there is power, check the pump motor as described in this

section.

3o If the pump motor does operate, let the timer motor advance the timer through

the drain increment to determine if the timer motor and drive train are fully

operative.

4. Let the timer advance, or index it forward to the portion of the cycle in

question..

5. If a component controlled by the timer fails to function as the timer advances

through the cycle, check for voltage at the timer terminals, tf the check voltage

is supplied to the component, check the component as described in this

section

Continuity through timer contacts, other controls, and wires can also be

checked with an ohmmeter with electrical power disconnected.

If the timers contacts fail to close in the sequence shown on the timer chart

are burned (have resistance measurable with an ohmmeter), or if timer does

not advance automatically, replace the timer.

To Replace Timer

I Disconnect dishwasher from electrical supply

2.. Remove the timer knob..
