Noisy boiler
Hi,
Can someone please help, we have a combi boiler very old 20yr+ VRT-OTA, VC/VCW Vailliant - not sure if this name is correct.
It has started making a loud noise as though a motor is running inside but is struggling??
Someone has suggested the boiler may need filling with water from the top?
Would much appreciate some help.
Thanks

This is predominately a North American based site and that boiler is a UK product. I looked up the manufacturer...... Valiant is a trade name. There would be an actual model number for that combi boiler.
That system should be running on an autofill system and you shouldn't have to add any water. I see that unit has an internal circulator pump. That pump may be what's making that noise.

And this is the boiler controller:
Any troubleshooting suggestions?
