Possible Causes

Worn or dirty program selector knob encoder, Loose selector shaft, Faulty user interface PCB, Broken connection between selector and board

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel.

  • Check selector operation: Rotate the program knob through all positions. If it feels loose, skips positions, or does not click, the mechanical encoder may be worn.
  • Remove knob and clean: Pull off the knob and gently clean the shaft and surrounding area. Do not use excessive force or liquids.
  • Inspect encoder on PCB: Remove the control panel to access the encoder soldered to the user interface board. Check for cracked solder joints and resolder if necessary.
  • Replace encoder or UI board: If the encoder is physically damaged or integrated into the PCB, replace the entire user interface board with a Siemens-approved part.
