Help needed for Worcester Bosch Greenstar R1. On fire up makes whooshing noise like filling with water. Green burner light is intermittent until eventually goes out altogether when boiler goes to lockout. Have checked whether air in boiler and seems ok. When system runs just with pump going no signs of air in system.
Strangely left pump running all night and boiler fired up perfectly this morning for about 10 minutes and then went into lock out.
Supect it is one of the sensors any thoughts. Thanks Colin
