I had the same problem with my 70lt Guten not long ago and it turned out to be a problem with the screen. I think they are about 35 dollars and easy to replace. Would be worth trying before buying a new system.So I go to brew a batch today as you do and upon cleaning my Guten as I normally would before every brew with sodium perc it trips off, now last brew out I was minutes away from ending the boil and the unit had tripped off, so I thought at the time.............. though it turns out it was my kids switching the power off, anyway, this time back upon cleaning the unit trips off when reaching around 30c-35c this now continues to happen, unit is around 2 years old 40L system, thoughts with the next step, should I just invest in a new all in one system?
Ok I think that's about what my gap is now. So maybe I wont adjust that yet, I'll see how I go with just conditioning the grain and not recirculating at the start. CheersHey Chris.
I leave my pump off for the first 10minutes after mashing in. I find this helps to let the grain absorb all it's moisture before recirculating and helps to get better flow through the grain bed. I also stir the grain every 10 to 15 minutes which seems to help with efficiency. I haven't used the top plate for a long time. I don't find a need for it just move the pipe to a different spot after stirring. I have my mill gap just under a credit card thickness and have never had husks got through the bottom screen.
I was pretty surprised that they didn't get picked up by the pump to be honest. Maybe something to do with the standing false bottom? I guess it could have made it through the bottom screen of the malt pipe while mashing, but sat on top of that until after I'd pulled the malt pipe and so didn't get filtered out?Even with a few husks going through they get caught by the recirculation anyway. If the grist was too fine you'd think less would go through as it would all set, maybe the stirring is pushing the crushed grains through? I don't stir after 15 minutes and just adjust the pump so the flow balances in and out nicely. I tend to use about 3.5 litres per kg of grain in the mash and similar volume to sparge.
Unfortunately this didn't happen for me. I only ran it for 10min after pulling the chiller. Maybe I need to go longer. Pretty much all the trub was underneath the false bottom. I also couldn't find my whirlfloc on brew day, so maybe this stopped it clumping up enough to work properly.False bottom will catch everything during the whirlpool where it will cone up in the middle.
