We have a Dometic CT4110 cassette. In the bathroom, integrated into the flush button panel, there are some lights that are supposed to illuminate when the cassette is, I think, 50% and 75% full. They don't. Initially, I diagnosed this as a broken float arm when I found the float arm had snapped off and was rattling around in the bottom of the cassette. The float arm has been replaced by the dealer under warranty, (used Pilote G650 2017 model).

The lights still don't work. Any ideas or experience of this? I read somewhere that the float arm contains a magnet that doesn't work if installed upside down. Or is there an electrical fault in the panel?

Try waving a magnet up/down in the appropriate place when the cassette is out. The button has to be pressed first to switch on the system (it stays on for a while).

Will be doing, but only just got back from a trip. Wanted to get ahead of the game if I could get any ideas from fellow Funsters.

Yep, I know the nagging feeling that it's probably something simple.
I once drove 180 miles back from Devon all the time wondering where a faint clicking noise was coming from. Upon arriving home I discovered it was the fridge igniter as I'd not changed the fridge from gas to 12v for the trip. :doh:

Good idea! Hadn't thought of that. Doh! What button are you talking about? Please don't tell me it's just a case of switching something on first. I'd assumed the full lights would show automatically.

The one on the panel that operates the flush.

Do you mean the actual flush button? If so, then no, the lights don't come on when you flush, even though the cassette is quite full..

Yes he did mean the flush button. Check everything g is plugged in on the back of the panel there are two or three looms that go to it.

Will probably leave that to the dealer as I can't see any way to get the panel off. Is it just levered out with a screwdriver?

When the slide won't move the cassette is full.

Why are things as simple as a toilet cassette so complicated.

Because it's compulsory to have a microprocessor in everthing these days. :LOL:

It is very rare that neither of us would know when the cassette needs emptying. You can see the surface of the cassette contents through the open slide at the bottom of the bowl after whichever one of us has just used it - and after pressing the button to flush the loo, we each check the bowl before closing the slide again to ensure that 100% of whatever we have just deposited has successfully disappeared into the cassette. The red warning light on the flush panel does still work - but by that time the cassette is getting a bit heavy to comply with the happiness condition of the chief cassette evacuator/cleanser - hence it's 2 days max use these days. (He now has COPD and a so far untreated abdominal aortic aneurism, hence neither of us wishes to make anything more difficult, frankly.)

I'm only bothered on the basis that the next owner might be, and why should I pay to fix it later when it could be done under warranty now. Agree with all the comments about just eye-balling the contents, but as just explained......

This got me thinking. We also have a Dometic loo will same lights. Neither of us have never seen the half full or completely full lights come on. We experimented today and discovered that the light to show cassette has been removed does work.
what is most irritating is that there is no light at night. This van has more different lights than you could possibly want, but nothing that indicates the location of the flush button for in the night. I am sure our previous van had one, but that was a Thetford loo. The symbol array, above the loo looks as though the centre should light up, but it doesn’t. Any one know any different?

I'll check to see whether the "cassette removed" light works. Never thought to look. What about the "watering can" symbol? What is that supposed to tell me?

I think it tells you the flush tank needs filling. Doesn’t apply for us as the loo just uses the water tank.

Same with us. Never knew some of them have a separate tank.

Well, a light came on today! We didnt empty the loo yesterday because it was raining too hard. This morning the "nearly full" symbol lit up! It's never lit up before, even when we thought the loo was getting quite full. I think maybe the tank just has a larger capacity than we thought!
acropolis22 - have you got yours working now!

No, it has to be looked at again by the dealer. (Waiting to receive spares for something else before it goes in. The wheels grind slowly.) It did occur to me that maybe we were being impatient, but it seems pretty heavy when I slide out the cassette, and there is a half full warning light too. This has never come on.
