Gas Hot Water Heater - Only Luke warm water

I have a Ruud PowerVent hot water heater Model # PVP40SF that was installed in 10-2007. I bought the house last year. Always had very hot water but this morning we only had luke warm water. It wasn't a cold morning and the heat for the house isn't on yet. Pictures below. Any suggestions before I call a Plumber?

Could be anything, but the vent proving switch might have failed.
This is the normal thing we look for.

Let us know what they say....

I called Ruud and Im unit is no longer under warranty . Plus Im not the original home owner so I'm out of luck. They said if the green dial is solid green to turn the dial to vacation(lowest heat) and push the blue button to off then unplug the unit. Plug back in and turn settings to normal after 5 hours to let it recycle. Still might need the board replaced. Also could be sentiment so I may need to drain it. Any thoughts ?

after rereading your message I turned it back on again. I heard the pilot light engage and it started to run.

hot water heater still running after 15-20mins. just turned on the kitchen facet and let the hot water run for about 5 minutes. Hotter than it was this morning but I would still say luke warm. Normally the water gets very hot in a minute or two. Any thoughts ?

ok 30-40minutes later and hot water heaters has stopped running.
Just ran the kitchen water again and its back to being very hot. Should I still have a plumber come out to perform a maintenance check or is there anything else I can do/look out for ?
THANK YOU !!!

If you want to pay for a maintainance check is up to you. The heater seems to be working right?

What temp do you have the front dial set to? Looks like one dot past the triange. That is good if its a good temp for you...

It would seem that because its a power vent your flame sensor may be dirty. And it may be an intermittent issue. Thats the most common but we do not really know...

Heck it may never happen again...

Thanks. I just spoke to my plumber and he said he would have done exactly what I just did. He also thinks Im fine and if it happens again he'll come over to take a look.
The temp gauge is set one past the triangle and that is what we're used to. I think Im good to go ! Thank you so much. Not only did I learn something new, I saved money on a service call !

Thanks again!
