I know it's obvious but do you switch the vans 12 volts straight on after setting up? I have tried to flush mine on occasion whilst travelling somewhere, and forgotten to switch it on!!!

Can you hear the motor running when you operate the flush Button?

Regards Jim

yes 12volt is switched on/no sound from pump.leave it filled and after about 2hrs or so it will start to work.
