Vaillant ecoTEC plus 824 won't turn on?
Found boiler off, nothing on digit panel, rads & water cold. Gauge showed lack of water pressure. Turned the taps underneath boiler and made pressure gauge rise. Tried on/off switch, but wouldn't come on. Bled rads, one had air in it. Tried on/off switch again, still nothing. Don't think pilot light is on, can you help? (please lol !)
