    Pls move if wrong forum.

    Cut straight to the chase... Made a brew, went to chill it and my CFC is not outputting any wort. Backflushed with co2 which bubbled up in the boiling wort, but still nothing coming out to the fermenter. Pump works (tested by firing all over the shop) so I know it's the CFC.

    Anyway. My freshly brewed prize experiment is sat in my GF in my shed having not been run through CFC to the Ferm bucket.

    I know many people do no chill brews but has anyone had to resort to leaving the boiled wort in the grainfather overnight!?

    Only saving grace I suppose is the temperature is veeeeery cold up in Sheffield. Fingers crossed it chills quick.

    I put in a fair amount of 10, 0 min hop additons and fear it will end up a mouth turning bitter bomb.

    Anyone else suffered the same fate with the GF CFC? Any solution?

    No I’ve never had a setup that uses a CFC. I know it’s a bit late but you could have knocked up a quick chiller coil?

    I haven’t don’t no chill before but I would assume it should be ok as long as nothing can get to it while it’s chilling and you are able to do a safe, exposure transfer.

    I have this issue quite a lot. Make sure the pump isnt blocked by attaching the recirc arm. Then re-attach the CFC and turn the pump on for about 30 sec then turn off for 30 sec and repeat a few times. I think either something is blocking the CFC or there is an air lock stopping the wort moving through. Works every time for me.

    It may seem obvious but check the flexible hose isnt kinked where it attaches to the GF.

    Did the no chill in the end and pitched this morning. Only concern I think I have is the late hop additions adding loads of IBU over the prolonged heat.

    Ah well.

    So I blew co2 down the outlet tube from CFC and it bubbled up like a witches cauldron in the GF, assumed this would indicate cleared... Evidently not.

    Someone else I was talking to mentioned about the airlock. Not something I have ever understood. Time to do some reading.

    I get the same problem often, if I chuck over 150g of pellets directly into the boil they cover the filter and my pump never gets going. Using a paddle I carefully scraped the top of the filter while the pump is running and the wort starts flowing through the CFC properly again. It seems when the filter is covered with hops the pump struggles to get going and needs a little help. I bought one of the mangrove jacks large spider for grainfather and don't have the problem anymore. When cleaning I always run the pump and push cleaner through the CFC so I know the CFC isn't blocked.

    So after much faffing about it was indeed hops in the CFC. I had the normal filter on and a bottom plate grate which does normally work a treat.

    Had to blow co2 through a few times both ends and an overnight soak to soften it up.
