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.

Dry the coni trap or rig something up as a temp coni pipe , turn boiler off , up pressure to 2/ 2.5 bar and sit and wait and see if anything drips down the coni pipe , if it does its nact .

I did get a drip or 2 down from the heat exchanger to the slump when turned off and all dryed out.

Yes you will get some , sorry I should have said , you will need to leave the boiler to cool down and any residual condensate to drain away , then up the pressure, after a few mins you will probably end up with a steady stream of water , if not just up the pressure a bit more .

I was getting it pooling in the back of there.

Follow towns method you will find it if it's there the air intake all comes off so you can get a better in the view in the sump it looks neglected from the picture ? . Kop

I did what you said townfanjon. And it worked a treat thank you. Definitely leaking he.

Depending on its age and your customer, it maybe worth a fixed price repair from ideal

I think the boilers nearly 10years old. What do ideal charge for a fixed price repair?

TBH I dont know exactly but it will be around £300 , but you wont be able to change it for anywhere near that . Ten year old , its time for a new one if customers funds allow .
