One Raditator Not Working After Power flush

[Madrocks]

Hi all, since our central heating was power flushed one of the living room radiators has not worked and pipe leading into it are cold. Its been bled, water runs clear out of it as soon as you bleed it. The boiler is a 20 year old Glowworm with a tank in loft and cylinder in airing cupboard. There are no TRV's on any of rads. The HW needs to be on for CH to work. It took approx 3 hours for system to be flushed. All other rads work fine. Any suggestions most welcome.

Thanks

Flushing can't clean a heating system completely, but the engineer should have tested all the rads before he finished the job. It could be a closed or faulty radiator valve, especially if one of of them is thermostatic. Some times it is required to remove and flush a radiator off the system. If a blockage us suspected in the flow or return to a single rad the flush plant can be attached to the pipe work where the radiator has been removed. If this tails, up the boards and re run the pipes.
