Our Vaillant EcoTec Pro 30 makes a loud clicking noise every few mins after the heating comes on. Eventually, after about 10-15mins it stops, but the weird thing is it also happens the same (clicks every 2-3 mins for 15 mins) after the heating is switched off.
Here is an edited clip of the clip happening 3 times. The first click is about 2 mins after the heating is switched on, the second and third clicks are after ~5 and ~8 mins when the boiler is running at full power.
Other than the clicking, everything else with the boiler works fine.
Any ideas?
