Start here — before replacing any parts
Setting the timer may only configure a cycle; verify the start/ON command on your KZ-S6 control panel.
The available KZ-S6 series operation guide covers operation and safety, but does not provide a complete electrical service manual.
Manual scope: Verify keypad/UI version first
Do these checks in order
Follow the steps below and keep a record of what changes after each one. Stop when an actual cause is confirmed.
Check the nameplate and panel layout against the KZ-S6 series instructions. Confirm the AC rating is compatible with the outlet.
Fill the tank to the permitted working level before selecting ultrasonic or heating operation.
Select a short cleaning time and press the actual START/ON control as documented for that panel; observe whether the display begins counting down or a status indicator changes.
If a cycle never begins, remove power and check for a stuck key, liquid spilled over the control area or a loose external plug. Do not probe inside the control housing.
If the problem is gone
The timer begins and normal operation starts after the correct ON sequence: no component repair is needed.
If the problem is still there
Panel lights but will not enter a cycle under correct conditions: record the exact panel behavior for model-specific electrical service.
Which cause matches your result?
Use these more specific checks only when the earlier steps point to that possibility.
01Setting the time does not start the ultrasonic cycle
After selecting a duration, check whether the machine remains in standby.
Use the ON/OFF control as the manual directs to start the cleaning cycle.
02Nothing happens after correct setup
Check the external power supply and safe operating conditions.
Do not assume a failed control board without a compatible model service procedure.
How can I tell it is actually fixed?
Confirm that a short timed ultrasonic cycle runs and ends automatically using the expected controls.
Before buying a replacement part
Control-board and switch arrangements must match KZ-S6 panel variant.
