Ideal boiler condensate traps can get very dirty and eventually blocked if they are not cleaned out.
They get full of all sorts of weird gunk and sometimes bees and other insects that get in through the flue terminal outside.
I have been servicing boilers for a decade and I have cleaned my fair share of Ideal boiler condensate traps.
In this post I’ll explain how to clean and give my best advice based on my on-the-job experiences over the years.
How to Clean Ideal Boiler Condensate Trap
If you have your boiler serviced regularly then your condensate trap should be cleaned out then.
If not, then cleaning it every year or so could stop it from getting blocked and causing your boiler to lock out.
To clean an Ideal boiler condensate trap you need to remove it from the boiler and run it under a tap and keep shaking it vigorously while keep filling it with cold water and emptying it.
How to remove an Ideal Logic boiler condensate trap:
- Turn the boiler off and isolate the electric supply at the spur if possible
- Loosen the two screws on the bottom corners of the boiler
- Unclip the casing from underneath and remove the casing
- Unclip the control panel and pull forward
- Remove the black rubber tube on top of the condensate trap
- Twist the trap anti-clockwise then lift up and remove it from the boiler
If you have an older Ideal Logic boiler, you might have a screw-on cap under the boiler keeping the trap secured to the boiler.
This cap will need to be unscrewed anti-clockwise and removed to remove the trap. Make sure to have a bucket underneath to catch the condensate water.
How to clean and refit an Ideal Logic boiler condensate trap:
- Pour out the dirty condensate wastewater from the trap into a sink and fill it with fresh water
- Shake the trap vigorously and empty
- Repeat until all the gunk inside the trap is removed
- Fill with water and hold straight above the sink, let the water come out of the bottom
- Fit over the rubber seal and make sure it sits in the seal properly and the other bit sits in the slot
- twist the trap clockwise to lock it in place
- Refit the black rubber tube with the double pipe end sitting in the trap
Ideal Boiler Condensate Trap Full of Water
An Ideal boiler condensate trap should always be full of condensate wastewater. This is completely normal.
When it fills with water from the flue it will partially empty out of the bottom and into the condensate pipe and then to the drain.
Having the condensate trap full of water stops the poisonous flue fumes from coming through the trap.
This is what traps are made for. Just like traps on sinks are always full of water to stop smells and creepy crawlies coming through.
If your Ideal boiler condensate trap is not emptying at all, then it must be blocked.
Ideal Boiler Condensate Trap Blocked
If your condensate trap is blocked then you need to clean it out.
If it’s blocked with solid substances that can’t be removed then you will need to replace the condensate trap.
Cleaning or replacing the trap will unblock it but if it’s still not working then it’s probably your boiler condensate pipe blocked.
You will need to find and fix the blockage in the condensate pipe.
If your boiler condensate pipe is frozen then this will need to be thawed out before resetting the boiler.

Cleaning an Ideal Logic boiler condensate trap is easy but it is recommended to get your boiler serviced every year and the trap will be cleaned during the service.
If you’re just starting out as a heating engineer then this will be one of the easiest jobs to learn and a very common one to do as most new builds fit Ideal logic boilers.
This is the same process for Ideal Logic combi boilers and system boilers.

Ideal Boiler Condensate Trap FAQs
Where is the condensate trap on my Ideal boiler?
The condensate trap on an Ideal boiler is inside and on the very bottom of the boiler.
You will need to remove the boiler casing and pull down the control to see and access the condensate trap.
How do you stop a condensate pipe freezing?
There are a few things you can do to stop a condensate pipe freezing in the winter.
The first and easiest thing is to do is insulate it, and the best thing you can do is to fit a trace heating cable.
What happens if the condensate trap is blocked?
If your boiler condensate trap gets blocked, the condensate wastewater will not get discharged and this will cause your boiler to lock out and stop working.
What does F1 mean on an Ideal boiler?
The Ideal boiler F1 fault code is for low pressure. You will need to repressurise the boiler to get clear the fault code and get your boiler working again.
