First jaunt and overflowing already...

[Fatmrsgeorge]

Well we have lost our virginity and are on a jaunt to Melrose. All is well. Toasty. Heating and hot water all operating as they should. We have done our dishes. Tested the shower for 20 secs. Washed hands ×2 . Now getting an alarming beeping sound to let us know our waste water is full.
Can this be true ?

Not even had a shower yet......

Once used, the waste tank sensors are very susceptible to getting gunged up with residue that is conducive and can give a false alarm.
If you know it was empty when you started and haven’t used much fresh water, you can be fairly certain that you can ignore and mute the warning.

20 seconds testing the shower. I probably don't run it for much more having a shower. Washing up if you do it like at home will probably use more water than necessary too.
Saving water becomes second nature, for instance don't run the hot water to waste until its hot and then have to run cold because its too hot. If hand washing don't run the water unless your hands are actually under it.

Thanks. Is there a way you can get in.to clean the sensors ?

Usually four screws holding it in place on top of your waste tank. Or just disconnect until home.

If you started with an empty waste tank you will have enough room for whatever is in you freshwater tank.

Thanks so much. Very reassuring for us - the least intrepid travellers of all time. .

You can use Thetford grey water tank cleaner fluid, which will clean the sensors as you're driving around (you'll need to have some water in the tank as well).

Bung in 1 kg of food grade citric acid, plus water and let it do it job, as it’ll also descale as well, its been keeping my fresh and grey tanks clean for many years

First things first... do your tanks have access caps to see exactly how much waste/ fresh water is in them?

That's what I was just going to ask.

Just turn off the tank alarms if you can, you'll soon get used to how long you can go before the waste tank is likely near full.

I've tried tank cleaners to little avail. When I clean the fresh water system to kill any bacteria I run most of it into the waste tank afterwards and leave for 24hrs before draining. At the end of each trip I'll empty before driving home, but run any fresh into waste tank up to about 1/4 to slosh about then drain on driveway. Helps, but waste guage is still unreliable.

I remember driving up through Spain in freezing conditions and a drop of water must have frozen on the sensor in our first IH. Nearly drove us mad until Nick managed to work out how to turn the beep off. Oh the relief. We were on our way back to the ferry so needed our sleep.

A couple of dishwasher tables and a load of hot water in the tank then go for a drive, I find it works well. Also good for cleaning the loo cassette.

Thanks. We will sloosh it about and see what happens.

Fresh water tank I can see inside from hatch in floor. Waste water - I can't see any access point.

Usually no access unless it has a large drain cap underneath. There are various cleaning options that can be added with water and have a drive around to clean the sensor tips.
In my experience, results are limited and I tend to disable the alarm and work out from the fresh use an appropriate level of waste
