Hi

I wonder if anyone can help.

I have tried emptying the waste water which is clearly full but nothing is coming out. The light is flashing on the control panel too.

Any suggestions?

Thank you in advance

:)

Try turning the waste pipe tap back and forth as there may be something stuck at the tap exit.. Or if that fails, try and pull the compete tap and pipe off.. First acertain that they are push fit pipes !! Keep yourself out of the way, the waste may well smell "awful"

Are you sure that the tanks are full and that it is not just the sensors giving a false reading?

Hi have you tried pushing a screwdriver or something like that into the tap,try the tap handle in different positions,if this does not work try taking the tap off the pipe (make sure you wear old clothes it will stink)
Also have a look under van and see if there is a plug in bottom of tank.

Living the dream.
Could be a wodge of hard fat stuck. As has been said hands and knees job to have a look underneath MoHo to check out the pipe work from the tank to the tap. Mine was slow because someone had cabletied it up out of the way and made the water run uphill!

Firstly a big WELCOME to the Fun.

Now, are you sure the tank is full as motorhome warning lights are notorious for inaccuracy and showing incorrect tank contents ... this goes for both waste (grey) and fresh water tanks.

If you are sure and J&M's solution above doesn't work the you could try dislodging any blockage by pushing a flexible wire (net curtain Wire) up through the drain valve.

EDIT while I was typing these ideas have been raised by others.

Hi

Thanks for your replies. I will try the screw driver and plug idea. Thank you :) That might be a job for tomorrow.

Also, yes, I had just read about the sensor and it might be that too. Thank you for sharing that idea too :)

What is strange is that we can't get any water out of the tank at all. We know there is waste water in it as we have used 50-60% of the fresh water we had.

Any ideas on hoe to get it to release the waste water it is holding?

Thanks :)

Thanks again! The flexible wire sounds like a plan too. Cheers :)

nowhere near long enough
Very seldom that our Rapido does that but if you are near to a tap stick the hose up the outlet. Last time we had a problem it was a broad bean stuck in the tap. Failing that there is a removable plate covering a big screw cap under the van but do not do it in your best bib and tucker

brought first van 16 yrs ago
Because of the recent debate on emptying waste water into roads, public drains and like i believe the Rapido van has installed a valve blocker which only works if you are in a field and after dark. unlike Hymers they are active all the time.:reel::reel:
Failing this try the old stick plastic tubing up and suck hard but as others have stated stand well clear when the gushing (emptying) starts to flow.

Is your van single floor or double floor? Alde or hot air heating?
If single floor/hot air the waste tank has a plastic outer tank surrounding so that hot air from heating system can circulate around and stop it from freezing.
There is a panel held by a couple of screws in the underside.
Remove this and you should see a big plastic drain plug about 4" diameter on the underside of the inner tank.
Unscrew this and depart rapidly else you will get drenched in smelly grey waste.
The waste pipe coming out of the tank is push fit and can be pulled out to check if there are any blockages upside of the valve.
if double floor or Alde I can't help I'm afraid.

That's a possibility pappajohn. My other half said he thought it was already opened before I touched it but we're not 100% sure. A big day of cycling in snow and rain befuddles the mind ....

Maybe run a bit of water through & turn the tap in all directions, before all the under-the-van activities then, just to check? :)

Fire a hosepipe back up the outlet, that might loosen things up.

Having a couple of years experience on here I still cant tell when some of you are joking

Please tell me you don't do this yourselves, or if you do you wait till you are at home on your own hose, or at least use the waste water area hose

You will have people using the fresh water supply hoses o_O

So does mine so I disconnected the sensor wire from the 12 volt distribution box. We know when its nearly full as the water goes down the kitchen sink slowly. Problem solved

If i run out of fresh water my waste is full...BUSBY.

it could be that the handle on the valve is not turning the valve sometimes the valve handle turns and does not turn the little ball in the valve .try pushing up the valve into the tank to see if valve is open or blocked
