Possible Causes

Faulty function selector switch, Child lock or demo mode active, Failed low-voltage control circuit, Broken selector knob shaft

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the control panel.

Step-by-step checks:

  • 1. Check for child lock: Refer to the user manual to disable any key lock or demo mode that may prevent operation.
  • 2. Inspect selector knob: Ensure the knob is not cracked and that it turns the internal switch shaft.
  • 3. Test selector switch: On mechanical models, remove the control panel and test continuity across the selector contacts for each position. Replace the Hotpoint-Ariston function selector switch if contacts are not switching correctly.
  • 4. Electronic models: If the selector is electronic and no relays operate, suspect a main control board failure.
