Nuevo Ek

The flush in the toilet of my 2008 Nuevo has given up the ghost.
I have opened up the little panel beneath the flush button and the tank is full of gunge, I have looked for a dump valve but can find no trace of one.
I will have to empty the tank to give it a good clean.
I am also having trouble removing the plastic covering the switch and connecting wires beneath the flush button as I will have to replace the defunct pump. I have removed the rubber cover but I don't want to break the plastic one underneath.
Any help greatly appreciated.

I'd check this before ordering a pump.

Thanks for the reply Al.
Yes, I did find a blown fuse in the cassette locker but I didn't have a spare and I wasn't sure if it was only for the "Empty Cassette", warning.
I will change it tomorrow.
I did see a small rubber bung, top left, as you said in the cassette compartment. I wasn't sure what it was for so left it in as seemed a bit small for a drain plug. I will pull it tomorrow.
I appreciate you taking the time to reply and I hope that you will be back on the road again now that Boris is letting us out.

Great advice!
Everything found as explained and now everything cleaned and repaired.
Thanks Al, you have saved me a lot of grief and a bit of money as well.

The gunge is usually the pink additive that people insist on adding to flush water. It lines the sides of the tank and gradually builds up over time. It's responsible for the unsightly dark bits that find themselves in the toilet bowl and can lead to pipe and pump blockages. 

My van toilet was a model without a separate water tank or pump and used the van's fresh water tank and pump for flushing. Obviously you couldn't add pink to water that was also going to be used in the sink and go through a boiler too. My toilet operated perfectly well without pink and saved me carrying and buying one bottle too.
