Please help me! My problem with fixing my Zanussi WDT1085 Washer Drier is still ongoing. I have removed the facia and the programme knob. When I turn the metal shaft that the programme knob is attached to (and that pokes out of the programme(?) box I can advance the programmes manually but the Timer Knob Cam Disc (orange plastic) still turns freely without advancing the programmes. Obviously it is not attached properly to the metal shaft. I've trying to remove the cam disc, to check how it is attached and possible to replace it, but can't manage it. Do you have any tips on removing this cam disc?

I'm not sure which is the PCN number for my machine but here are some of the numbers inside the door.

Type: P6296154 Prod No: 914634051 00

Thanx Franny

Zanussi WDT1085 timer knob turns freely and does not advance programmes

The problem
On a Zanussi WDT1085 washer dryer, the programme knob/cam disc turned freely without moving the timer, although turning the exposed metal timer shaft manually would advance the programmes.
Likely cause
The accepted reply says the teeth in the control knob assembly commonly broke or wore down on these machines. This is the most likely cause if the timer shaft can still be turned and clicks round correctly.
What fixed it
Likely repair is replacement of the worn or broken part within the control knob assembly. The exact removal method for the orange cam disc was not confirmed in the discussion.
Checks to try
  • Programme advanced manually by turning the metal timer shaft
  • Timer shaft reportedly clicked round correctly when turned
  • Timer knob cam disc turned freely without advancing programmes
Parts or tools mentioned
  • control knob assembly
  • pliers

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello Franny: The teeth used to break or wear down on some of these machines. If the timer shaft can be turned by pliers and clicks round ok it probably just needs a new part within the control knob assembly. I can't remember exactly how they come off but it should be possible to work it out somehow. Something must come off to allow access to the shaft.
