Split heat exchanger on ideal logic

[Matt0029]

I went to a ideal logic that is losing pressure every week. So won't fire. Have checked all visible pipework and valves no sign of a leak. I removed sump cover on front of the boiler and there was water under the heat exchanger. I dryed this off left the heating off and the water came back. Has anyone had to diagnose this fault before. I can't leave the boiler off at c/h isolation valves to see. If drop is on boiler or pipework. As it's a slow leak and need the heating on. Thanks.

If its the heat exchanger it should be fairly obvious by the colour of the trap water.
Did you get the job of replacing the boiler?

Yes Shaun I could see it dripping from the back of the hex too when I removed the little cover of the front of the fluing system. I guess there shouldn't be any water dripping from the hex even when hot? As the condensate all comes down the front through the inner flue duct and back to the trap.

This is a different boiler. But looks to be same problem. Yes I did swap the Las one.
