I work with (not for!!) Viessmann. No you don't have to strip down the boiler that's nonsense. Just get it serviced by a gas safe installer annually and keep the records. You can buy a service kit for your boiler to see what needs changing. Normally it's just ignition & ion electrodes & gaskets,  burner gasket, maybe one other random gasket just for fun. 

Thanks for this! Here's the standard checklist Viessmann sent me. Does it look like a standard service to you? I'm not at home to check the previous year's report, but the service lasted 30-40min last year.

I'm due for a service on a Viessmann 050 (booked for 15th July). From watching the engineer on the last service, your check list covers everything that was done. If there is anything to add, I'll let you know.

Scratch head to work out how to remove front cover.

Check pipe connections gas/water leaks.

Check valves under boiler operate.

Check expansion vessel pressure.

Check & clean ignition terminals.

Measure gas pressure @ meter & boiler (and confirm pressure drop is within spec).

Measure combustion gas levels.

Visual check of flue & connections (mine is a little more convoluted than most).

Check & clean magnetic filter.

Replace front cover and clean up.

Previous service, the combustion chamber cover was removed. Not this time...

Have been advised to get a spare gasket (rubber O ring) for the mag filter. Nothing wrong with the existing one, but best to have a spare and avoid paying top price in an emergency.

Sop useful! Thanks! May I ask what the price for the service was? And what app are you using? I have the Nest and I think the Viessmann app on one of my old phones.

Service was £90 including VAT. That's about the going rate in this area.

The "app" I use.... (you asked for this ) Home Assistant to provide the web based interface and data collection. ESPHome handles the low level OpenTherm interface and have openHASP running on a small wall mounted display to show the thermostat (also doubles up as a light switch along with a few other things).

The engineer was able to access everything he needed from the front panel on the boiler (just needed to put in to "service" mode). Now know just how much power the boiler will shove in to the heating when run flat out - Quite an impressive 20.6kW @ 80.6°C flow temperature. Over winter, most of the time I was running at 4-6kW @ 40-50°C with an initial burst of 8-10kW at startup.
