White Knight 76AW condensor dryer

To get the machine to start you have to push the water container and either hold it or wedge it to start.

Adjusting the tensioning spring at the back has no effect and there is no adjustment of the rear micro switch itself.

Is this a common fault, is there a mod or will a new micro switch assy be the only option?

If so does anyone know the part number of this?

Thanks.

Jim.
