Troubleshooting the Timer
If the timer is suspected of faulty operation, refer
to the Timer Cycle Chart and Timer Strip Circuit
and proceed as follows:
1. Index the timer to the first increment of the
Pots and Pans cycle. (This is a drain period
which activates the pump motor.)
2. If the pump motor fails to operate during the
first cycle increment block, check the power.
If there is no power, check the door latch
switch. If there is power, disconnect power
and check the pump motor component resis-
tance (see
Specifications page 2).
3. 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.
If the voltage is supplied to the component,
check the component resistance (see
Specifications page 2).
With electrical power disconnected, continuity
through timer contacts, other controls, and wires
can be checked with an ohmmeter.
If the timer contacts fail to close in the sequence
shown on the timer cycle chart, are burned (have
resistance measurable with an ohmmeter), or
doesn't advance automatically, replace timer.
