For the benefit of any Newbies with a flushing issue. 1) This video only relates to toilets with a separate flush tank. Toilets which use the main water pump to flush with water from the main water tank are very different. 2) The common cause of the impeller getting jammed is black flakes forming in the flush tank. The major cause of black flakes is leaving the flush tank standing with a solution of pink fluid in when not in use. a) Drain the flush tank at the end of each break; b) If it will be unused over winter, flush the flush tank with plain water before draining.

[@moff01]

Hi, just a quick thanks, went through everything and it was the pump. Sprayed with Plusgas and turned the propeller carefully with a small screwdriver and it burst back into life.

[@dustymil59]

Thanks for your video, the only one that explains how to check the components. My fuse (2020 Coachman) is actually on board the main fuse board and shared with the external water pump.

Mine is C262 model. The fuse is in the main 12volt fuses under Sprite caravan seat. It turned out to be the tiny pump in the cistern was seized and just needed a spin with pointed tool. I accessed the pump by peeling back the label on the flush switch and prising out the switch assembly. Then remove the 2 screws and pull up the pipes with the pump on the end. Surprising how much scale and bits had accumulated in the pump impeller. Thanks for giving me some clues 👍

Hi there this is a good video is there any more tips and tricks as my one is not working I’ve changed the board the pump is working I’ve changed the fuse and it’s still not working

[@thecaravanplace]

It's testing where you have power, start at the power coming in or on both sides of the power, then if you have power getting to the board? Then pressing the button and do you have power to the pump wires. It could be the wiring harness if you have power getting to the board. The little white connector that goes on the board could be faulty and needs replacing if you have power getting to the board. Hope this helps.

[@dlov011]

[@krypton9984]

Great, thanks, helped me a lot. Confidence is everything. Mine didnt work after the fuse and the board behind the button, fixed it by replacing the board down below - the fill level thingy. These are simple systems, although I think in my case the pump is harder to find.

[@thecaravanplace]

Great to hear.👍

[@peterward2357]

Did you find the pump? I cannot find mine so I am assuming the main water pump must be used for toilet flush. My intermittent problem seems to be at the connector to the switch logic board. Don’t think I could replace the connector even though it looks clean and no corrosion.

My thetford toilet with a C250 cassette is intermittent in working, I’ve removed the flush plate as shown but there isn’t a pump in this area, do the toilets have a separate pump or could it be the main water pump that is being used?

[@thecaravanplace]

Hi Peter, the pump will either be top right from when you look at where you take the cassette out from outside, or when you remover the push button control panel, you will see 2 screws that hold the pump but this is the c260 model where the pump is inside.

[@peterward2357]

@@thecaravanplace : thanks for your info, with the cassette removed there are only cables going up to the toilet flush, removing toilet flush panel it lifts out with about 12 inches of slack cables, removing the 2 screws and there is only daylight looking down to the cassette area, the screws do not hold anything in place in fact you can see daylight through the 2 holes. So no pump in this area. Maybe my 2008 motorhome has a hybrid C250 toilet. I have photos if I can attach them to my comments I will, your further advice would be appreciated.

[@thecaravanplace]

Sounds like the button is stuck, or shorted, so sounds like a new pcb possibly, try pressing the button lots to see if it fixes it.

[@TCSC47]

At 2:00 a degreaser is sprayed on the fuse. By itself this will do nothing. Any grease or dirt on the pins will not be removed unless you use a clean cloth to wipe off the grease that will have been dissolved by the de-greaser. Also you really shouldn't spray the solvent onto your bare skin.

[@MarcinAdamowicz]

Multimeter shows -13V (minus) when I check red and black wires. Why minus? Is it normal? Anyway my problem is if I switch on main power switch in the campervan, that c250 PCB heats up quickly and would probably melt if I won't switch of main power. What can be wrong? Polarity? Or PCB dead?

[@thecaravanplace]

Yes the minus is saying the positive and negative are wrong, if u swap the prongs over so red goes to black and black to red, it will read correct if it is wired wrong. You will need to try and find where the power comes from and see the supply to the toilet is wired wrong?

[@richardnorton2858]

When I checked ours a cable has come out of the connector. Any ideas how to reconnect please.

[@gwenjohns6844]

Our toilet stopped flushing at the start of the season. I checked the fuse which seems to be ok. The red toilet full light is working but not the flush. I’ve fitted a new control panel but still nothing . Any advice please.?

[@thecaravanplace]

Hi Gwen, you need to test if you have power on the board, so twst if power is coming to the board and then test if you have power going to the pump when you push the button. If you have power when pushing the button, its the actual pump, if no power then its finding why you don't have power.

[@gwenjohns6844]

So the fact that the red ‘toilet full’ light works doesn’t mean there is power going in?

[@thecaravanplace]

Possibly to the board but that might be from the sensor that says the cassette is full. If u start at the pump wires on the flush board inside, check you have power then to rhe pump when pressing the flush button, if not work backwards and check the power.

[@gwenjohns6844]

Ok thank you.

told my dad about this video, checked the fuse first and it was corroded so he cleaned it and tested it with multi meter and it was completely dead so we are fairly sure that it is that. We've also recently replaced the grey and orange toilet cassette as that had also broken (the opening ring blade mechanism had corroded/split so we believe that the toilet must have leaked because the cassette was broken and the fuse has got wet which would explain the corrosion. Not 100% sure where to get a replacement though.
