Worcester bosch 240 boiler. Put central heating on and some radiators had air so I bled them. After this, the pressure gauge on front of boiler dropped to zero and heating will no longer operate. How do I pressurize the system so the gauge comes up to 60bar.

under your boiler there should be a cold water infeed pipie with a inline tap, open this tap slightly and you will hear the water flowing into the system, watch the pressure gauge on the control panel and close the tap when the pressure reaches the indicator set point (usually set around 1Bar) make sure all radiators are bled of air and recheck water pressure and top up as above instruction.
