None of the above, your green water is down to your UVC if you have one in the system, you need to, depending on which one you have, check it is still working, DO NOT LOOK DIRECTLY AT THE LAMP, it may need a new lamp fitting depending on how old it is.
Filter wool is not the answer.
Would have been so much easier if we had known the full story.

This is interesting!!!
There are two uv units with 6 month old bulbs inline with the evolve.....but we can’t turn the evolve on as the draco dumps the water...,so, maybe just removing the drum filter from the evolve so the water passes through the uv units. (There is one unit in the feed and one on the return).

Appreciate other people might have said this, but to me there are only 2 possible causes, but also bear in mind parts of this thread are confusing as I think most people naturally assumed your filter is gravity fed (because that's what people expect when a drum is installed):
1) The float switch is faulty or is adjusted to a level where, due to the excessive amount of dirt and instant drum re-blocking, never gets the chance to switch the cleaning cycle back off, i.e the water level isn't dropping enough for the float switch to stop the cleaning cycle, then the "failsafe" cut out kicks in.
2) The pump is pumping too much for the drum to cope with in view of the amount of dirt in the water.
I'm not familiar with this specific drum, nor a drum that is pump fed, but my initial suggestions (guesses based on limited understanding of your setup) would be as follows;
Raise the float switch as high as it can operationally go . Yep, this will cause the drum to dump water constantly, but does the cleaning cycle now cut in and cut back out again as it should?
If it does then it sounds like there's too much dirt being pumped into the drum for it to handle, i.e the gap between cleaning cycles has become shorter than the cleaning cycle itself, hence the failsafe cutout.
If your pump is variable then you could try lowering the setting, or alternatively try a less powerful pump. Once the water is clean again you can go back to how you were set up previously and the drum will cope.
My drum is gravity fed and I seem to be having a massive algae die off at the moment. Yesterday the drum was cleaning every 2 minutes! I turned the variable pump up to full speed to see what would happen, and the drum did exactly as yours is doing - Stayed on cleaning cycle for 4 minutes and then triggered the failsafe cut-out. Hence my suggestions above.

Me I would empty the pond like you said you was earlier in the thread. And jet wash all the algae off the pond. Reason.
If you empty and just fill back up. It will stay as it is. To much alge.
A real good deep clean. And do the drum as well.
Where are your fish. If in the pond a vat is needed.
And put new UV bulbs in.
Then if it still does the same. You know it ain't dirty water and alge causing the problems.
I know it is drastic. But at the end of the day. Sometimes needs must.

Couple of suggestions for you above Maj.
Another one,if you can slow the pump down a bit to give the drum a chance to clean,if you cant then put a T after the first UV feed.
When T'd put a valve and let that flow into a container with jap mat or similar to catch green water then back to pond.
The idea being to slow down the drum flow and let the drum catch green algae.
Presume the UV are switched on.John

Yes, the pea soup is a byproduct of the system failing due to various components.
Now that the system is fixed, I’m trying to get through what to do next.
I can’t raise the float valve as it’s at a fixed height.
Slowing down the pump is the only option but I don’t think that can be done.

Slight update. We dumped a lot of the water and refilled it.
I disconnected the coupler to the drum so the water would go straight through to the jap mats.
It’s clearing but slowly.
There are two uvs on the system, one before the evolve and another after it.
We are still going to have to get the pond clean properly but this is a start to getting it running properly again.

Where are you located ? it sounds as though you need somebody whos got a Draco there to actually
watch it in the flesh' '' so to speak ''and see what is going on with it .

When you say dumping loads of water do you mean constantly cleaning?
If so check the float level,just after clean the water should be just above the float.
Pond looks a lot better maybe still a lot of crap on the bottom.John

Yes, constantly cleaning but the cleaning cycle timeouts out as a fail safe as it runs for too long. So the water just rises in the drum then through the overflow.
No gunk in the drum that’s stopping the water.
The crap at the bottom is being dealt with - bought another filter with sponges to clean the water.

Could you take a video of what it's doing on your phone and send
it to Tony at Draco.

You should take a video showing the complete setup, inlets, outlets, pipe work, how the drum behaves etc, upload to YouTube and post it.
