This is the same issue i had. I swear the stem on the float switch is not long enough.
If your timer workaround doesn't work or fails after a while, perhaps try dropping the float switch so that the stem is essentially hanging loose and lightly clamp the cable in place instead.
I did that back in November time and it has been working well since then. It yo yos a bit, but it's found it's level now. I now only get a bit of water overflow the waste chute if I've done a recent water change and add more water than I purged.
I think the problems you are having is (apart from getting the drum and sensor height fettled) simply because you are trying to pull too much water through the drum.

i have my trickle in flow higher volume of water going in than what the drum and over flow wastes
my new jet nozzles use half the water previous nozzles used , im sure you could change your nozzles too.
i find it easier maintaining a constant over flow to waste via a 1/4" tube connected to wall skimmer at a pre determined height rather than a water line as too many variables to consider and likely the level will drop in warmer weather for example.

I've wired up the water level sensor temporarily in the old pond.
This is made simple by the switch box. I use an unused port - put the cable in, clamp it then send the cable over to the pump connection (#1 port on this set up). I use a electrical connector block then put electricians tape around the block.
With the switch I have - the brown and black are connected when the sensor is at a position it would be at the right water level. The blue is connected if the sensor points down so this doesn't need connecting so I simply terminate the cable in a block and then wrap that in electrician's tape just to insulate it. Should the water level drop and the sensor triggers - this blue would then end up with the power applied to it - so it's vital that this is insulated and not simply cut and left dangling.
The brown wire then simply goes into the switch power block (the grey block).

Then I've positioned it on the side - the float in a spot that it will not be kept upright by Lilly pads for the pump pipe. I just used a plastic thing with two screws to clamp to the wood.
The float doesn't have to be straight up - it can be on an angle. As my pond isn't that deep, I want it to trigger sooner rather than later.

Update
Thats 3 full days of running without any hiccups, I can switch my waterfall on and off now without causing the Drum to have a fit, I can backwash my bead filter now without panicking about getting the levels correct again...............its all done automatically now

Hay Nick I have exactly the same float switch in my suction pit, I had an Electrican instal mine, as I am not comfortable messing with electrics. Just a thought you could have the switch inside a bucket (with holes in it) that sits in the pond, that way no way for the Lillies to mess with it.

Well it earned it's stars today - I was fitting a new water pipe (MDPE pipe) but forgot I pressed the emergency stop (latching) on the controller.
As the old pond is pump-fed and the drum blocks (this is the same for most RDFs that don't have a a weir bypass) the pumped water was overflows the waste chute.
I popped out to screw fix for some additional bits.. and I was fitting and thought - something doesn't sound right. Sure enough the newly installed water level sensor had stopped the pond from being pumped dry:

Here's the sensor:
IMG_8142.jpg
The air pump is still running and it doesn't seem to yo-yo the water level as I thought it may.
I now have the dechlorinator running - so this is working it's butt off (worth the £50 for the 3rd time vs the amount of pond start I'd have needed).
One thing I think the Draco controller should have is a warning buzzer or bleeper that runs when the emergency stop is pressed. That would stop this scenario where you get distracted..
So this is the third time that a scenario where the drum has blocked causing an overflow to waste.
The good news is that in the new pond the gravity feed will not allow it to empty in this way, regardless if it's running on airlift or pumped.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

That wouldn't work in this instance - this is pump fed, and the system's emergency button was latched on (my fault). With pump fed the longer the drum is blocked the larger the overflow.
However on a more positive note It gave me a chance to open up the waste and have look inside the drum completely.

The sand and grit in the drum inlet chamber and on the red seal. Cleaned that off.

The waste chute is relatively clean (I'd cleaned it about a month or so ago). It also shows why it's important to be able to get the chute out to see the entire drum.

So I selected #4 wash and gave it a manual..

What is also clear from this is the browny stripes on the drum - the bio film build up. Which would explain why the drum has been washing more recently.
Also near the inlet there's quite a bit of waste build up - maybe worth adjusting the spray nozzle or even adding an additional spray nozzle so they're closer together thus you get more pressure. Either way it needs a good pressure wash once the pond is re-filled.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

Just sorting out the MDPE. They need better pipe collars too.. so my solum16 is out of action, I've opened the bypass.. yet more crap to add to the pile to sort out.

Question
With the drum running in gravity mode does it matter if the running water level is below the Bottom of the frame........ . see picture below
Still getting lots of water in the drum via the 3 inch bottom drain line

So as long as you have a decent inlet water level (ie maximising the wet drum area in use) you could run the drum clean side completely empty.
The only issue is that all the pressure of the water is against the mesh - if there's water on the clean side it helps to support the mesh. However if the water level is below the drum rim then you will not get any water flow through the there drum.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

New part ordered along with the solvent and cleaner - I've been away in France unfortunately so until now the system has been on bypass.
Can't wait to get the system back online. Think the fish are like "hey dude.. you forgotten about us?".
I'll try heating and removing the bond then replacing the coupling side.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

New coupling arrived - different make, so it won't screw onto the existing other half of the coupling (a typical issue with fittings). So I will remove the coupling by sawing the fitting then using a chisel to remove.
I'm hoping that the size of the fitting is small enough not to pull the spray bar out of the drum area as the fitting is a little wider.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

So the coupling surgery went very well - there's a couple of techniques, depending if you want to save the pipe length or the fitting. In my case it was to save the pipe length and replace the fitting.
Dremel with a cutting disc two cuts into the old fitting (this is going to be destroyed) about 1cm apart, just down short of the pipe itself and then use a chisel with a mallet (be very careful) and the fitting comes off in fractured pieces - you then simply use the chisel to remove the other pieces.
IMG_8209.jpegIMG_8210.jpeg
Use the chisel to remove any little bits left and I used emery paper first. A dry fit to just test first..
IMG_8211.jpeg
Next up use the Griffon cleaner/primer and then I used Tangit solvent on the inside of the fitting and the pipe.. push together hard for 20 seconds and wish bash bosh - it's stuck. Clean up any residue with a damp paper towel.
IMG_8212.jpeg
I'm giving it 10 minutes to fully harden inside before I start playing around with fitting into the drum.
On a side note - if you want to save a fitting but destroy the pipe.. get a holesaw that fits inside the pipe. Use a wrench and then heat it up for 2 minutes using a propane torch. Put inside the pipe for a minute then the pipe, remove it and thePVC pipe is flexible, so use pliers and rotate it them, the pipe them comes away leaving the fitting. Just be careful of seals etc and remove the fitting union first and the seals if you can.
EDIT:
Success There's a very small weep on the elbow glue join - so I will simply use some sealant to solve that at a later date. My first every solvent glueing I could have perhaps put more glue on the inside of the fitting but hey.
I set the pump to 10,000lph and stirred up the bio (as this had been taking the brunt of the bypass flow).. the drum triggered every few minutes. So I got out the Karcher jet wash and gave the mesh a blitzing with the lance (not the stone lance) whilst it rotated. That seemed to have helped immensely as the flow rate is back to normal. I had noted that it had been washing more frequently and the bio film could be seen on the inside.
The 25mm MDPE pipe gives the system a lot more pressure based on the noise and flow rate. Even still - that pressure doesn't seem to translate to spray cleaning particularly well. Perhaps the jets need a clean out but it seems to do the job. I've left the system running at 10,000lph and turned down the tap pressure back to normal - there's no point in wasting water if it doesn't clean any more than a lower pressure level/flow rate.
Later tonight I'll back the pump off to the normal rate but the pond should be clear tomorrow
My gawd the drum needed a spray clean with it being on bypass:

After going nuts washing almost every minute following the new coupling being fitted and the drum back in service, I can report that the solum is back to ~50-77minute washes at a leisurely 6000lph. The pond has cleared, although it always takes a few nights for the fish to stir up anything before it's completely clear.
It does make a difference giving the drum a wash with a jet wash.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)
