Good morning, wondering if anyone on here is familiar with above? Fitted as part of bathroom refurb about 5 years ago. The half flush works ok but full flush just starts to make the pneumatic sound, then doesn’t flush. I don’t know if it’s the flush panel has the problem or if it’s the cistern (which is only accessible by removing the complete counter top and disconnecting the sink waste and taps)Any help is greatly appreciated, thank you.
