How to trouble shoot circulation issues for a hot water boiler

$

I have a residential crown cxe 5 boiler with a grundfos type up pump. I am getting inconsistent heating. I suspect that there is a circulation problem because when a thermostat calls for heat, the boiler comes on, but shuts off prematurely. On shut-off, the water temp is about 200 F, which I think is the limit temperature. The pump and pipes sometimes feel like water is circulating and sometimes not. How do I remove the cover plate on the pump to see it it is turning? Any other thing to check would also be appreciated. Thanks
