Well, its been 3 yrs since I put the WHN055 into service at the house and was greeted to an amber maintenance reminder. Currently sitting at 10250/8500 heating and 5270/470 hrs for DHW (cycles/hrs). Should I consider opening and cleaning out the combustion chamber/burner?

I did the install myself and honestly never even had the combustion analyzed... but it's been working great. Maybe someone can offer a recommendation for a local tech.

Yes it is strongly recommended to have it cleaned, gas and combustion tested. Check Lochinvars site for Companies in the area.
Have the technician print or write down the combustion numbers and leave them with the boiler for future references.

Are you mixing any temperatures with your system? Are you using Loch's multi temperature loop control?

Definitly clean it and get a combustion analysis done.
