Hi.
Boiler is a vaillant ecotec 615 unvented system boiler.
I have changed the diverter valve plastic body (obviously no diverter valve in it).
I had a tiny drip between this and the pump housing, so I have replaced this and replaced all seals around this and the pump.
Upon running the boiler after I completed, the pump runs very noisy and and doesn't quiet down.
Someone suggested the boiler needs to be put in "vent mode". I can't see anyway to do this.
Should this solve the issue and how do I do this?
Appreciate any input.
Mark.
