Petax K r with scroll wheel fault?

Hi I think our K r has a fault but just in case it's a setup problem I though I would ask around here.

The problem is that the scroll wheel causes apature and shutterspeed to jump to their highest settings as soon as its adjusted.
After this there is no way to bring these back down to sensible numbers like F5.6 and 125th, the wheel does not work.
You are left with no way of re-setting from F32 and a 6000th of a second!! So of course every shot is so underexposed its just black.

While trying to trace the problem we have found that the camera is still capable of stopping the lens down and that the ISO setting does not make any difference, oh and yes, the lens cap had been removed

Has anyone on here had a problem like this, and how can it be fixed?

Sounds like you have a faulty e-dial all right, it's a warranty job I'm afraid.

Yep, from what I've read it's a common problem caused by oil getting on the contacts within the assembly. There's a thread on it here.

A (temporary) fix is just to sit there and work the wheel back and forth for an extended amount of time. There are also some others that involve spraying cleaning on the wheel.

ah, think the camera's out of warrenty. My Dad's sent it off to get sorted anyway. That's a good thread, slightly worrying though.
