My toilet is self flushing every few minutes, I have to turn the power off to it, and back on when I want to flush it, otherwise it will continue doing it automatically. Any ideas what I should do to reset it. Does that flush panel ,flip off ,with a screwdriver, it feels quite strongly adhered, or should I be looking elsewhere? It only started doing it yesterday, I left it turned off overnight, but has continued this morning. I have only just had it pumped out.

I have a chinese no-name diesel generator that uses a 186F engine (clone of the Yanmar L100) that failed to start after being stood for almost a year with full fuel tank and decompressor open Fault 1 : in-tank fuel filter gunged up with orange slime (removed filter, tank cleaned, in-tank filter replaced with inline filter so it can be checked / changed without stripping the tank) Fault 2 : No fuel to injector.... taking the pipe off from the injector pump showed everything clean and seemingly good but no matter what it wouldn't pump fuel. after removing the pump squeezing the pump (very carefully in a vice with wood) would compress by about 1mm and then pop back out on closer inspection the pump was actually fairly seized in the compressed position and my 1mm of movement should have been nearer 10mm (stuck compressed by 9mm). moving the throttle lever on the pump was very stiff (far more than the generator controls could ever move) forcing it and wiggling it eventually yielded a pop and the lever freed off and the pump decompressed itself. after a little more wiggling (to make sure it wasn't going to just jam back in the old position) the pump was refitted and the generator fired up almost instantly (3 seconds of spinning over before releasing decompressor) just putting it here in case anyone ever has similar issues as these are fairly common (cheap) diesel engines and get used in a lot of generators and water pumps. an easy test for the fault is to slacken the three nuts holding the pump onto the engine, if it doesn't push itself away from the engine it has probably seized or you have a far bigger problem edited to add.... I can't complain too much about the generator as it is now 15 years old and spent the first 9 years of it's life running a 5kw load for 14-15 hours per day (weekly oil changes as that worked out at around 100 hours running) and apart from a bracket snapping from vibration (at 2 days old) this has been the first fault.
