If the boiler is constantly showing the error fault 06, it might be because of a blocked condensate drain.
Condensate can collect in the boiler’s water tank, and a blocked drain means that this water cannot empty.
To clear the blockage, you must find the hole from which the condensate is draining. Once you find it, use metal pipe cleaning wire or any other suitable tool to clear this blockage.
