Blurry picture
With the back off and if you can get a small mirror above the blue and the green tube, look at the picture coming out of the tube. If it looks like you're looking through fog then you probably have contaminated coolant. Compare them to the red tube for reference because the red one is very seldom affected.
If contaminated, the fluid will have to be changed and the chamber cleaned out by someone that knows what they are doing.
Be careful reaching in there. Wear gloves to help protect your hands.
