Hello there, daughter just moved to flat, when tried to start up boiler, it ignited ok then light came up showing A77. I believe this means water in condense trap. This was emptied and worked fine for a little while but after it was switched off and tried again the same fault appeared. Does anyone have advice re the above. Thanks
