Winterhalter Program Control / Sensor Feedback Issue

Machine runs continuously without switching to rinse or end of cycle; very long wash time.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Temperature not reaching setpoint, Faulty temperature sensor, Incorrect program selected, Control board fault

Safety first: Ensure the machine is supervised if it is running abnormally long.

Check temperatures: Feel the door or tank; if not heating, investigate heater and sensor issues.
Verify program: Confirm that a normal program is selected, not a continuous or intensive mode.
Reset machine: Stop the program, power cycle the machine, and start a new cycle.
Service call: If the issue persists, a technician should check sensor readings and control logic.
