How to Fix / Troubleshooting
Safety first: Isolate power before removing the control panel.
- Confirm door closure: Ensure the door is fully closed and latched. Check the door switch for correct operation.
- Reset program: Follow the Classeq manual to cancel any active program and reset the controller. Often this involves holding the start or stop button for several seconds.
- Test start button: Remove the control panel and check the start switch with a multimeter for continuity when pressed. Replace the user interface PCB if the switch is faulty or integrated.
- Inspect control PCB: If inputs are correct but the machine does not respond, the main PCB may be defective and require replacement.
