TROUBLESHOOTING - AUTOMATIC LIFT MECHANISM
PROBLEM
Basket does not lower when the
timer control pushbutton is
pressed after the knob is set to a
time value.
Basket does not raise after the
timer reaches a value of zero.
Basket lowers and raises
repeatedly.
Basket raises after the timer has
reached a value of zero, but then
sinks back into the tank.
CAUSE
Power is not provided to unit.
Power switch is not switched on.
Loose wiring connections.
Timer has failed.
Microswitch has failed.
Lifting mechanism or motor has failed.
Microswitch has failed.
Timer has failed.
Microswitch is improperly positioned.
Lift motor has failed.
SOLUTION
Ensure supply circuit breaker is “ON” and unit’s power cord is
plugged in.
Switch to ON position.
Check wiring and tighten all connections; especially timers, lift
motors and microswitches.
Set a time value using the timer control knob and depress the
push button. If the basket does not lower, jump the timer
terminals marked “C” (white wire) and “NO” (right motor – blue,
left motor – brown.) If the motor operates, the timer has failed
and must be replaced. If the motor does not operate, the
microswitch or motor may have failed.
Set a time value using the timer control knob and depress the
push button to start the timer operation. Check for 120V at the
microswitch by metering between the “C” terminal (white wire)
and the “NO” terminal (right motor – brown, left motor – black.) If
no power is present between the terminals the microswitch is
defective and must be replaced. If power is present and the
motor does not operate, the motor must be replaced.
If the motor operates but the basket doesn’t raise, observe
whether or not the motor crank assembly moves. If the crank
does not move but the motor shaft is spinning, the shear pin in
the shaft has broken and must be replaced.
If the motor operates but the shaft does not turn, the motor
gears have failed and the motor needs to be replaced.
If the motor does not operate, check for 120V power at the
motor terminals. If power is present and the motor does not
operate, the motor has failed and must be replaced.
See above.
See above.
Position the microswitch properly.
Replace the lift motor.
