My Tecma Silence Plus toilet would not fill after flushing.
Just got back from a short trip in the RV. At the end of day one, I noticed that the toilet flushed, the macerator operated, but the bowl would not fill back up with water. A little water trickled in, but that was it. I tried to re program the water level to no avail. Fortunately, my rig has a bath and a half, so we didn’t need to hit an outhouse.
This morning I called Thetford support. The gentleman that answered was very personable and certainly patient. I explained the problem and he told me that I probably had a water flow issue. He explained that there is a screen in the water line just before the fill solenoid and that it may be plugged up.
Armed with that knowledge, I looked behind the toilet. Everything is very easily accessed. I unscrewed the waterline fitting where it enters the solenoid. It was absolutely plugged up with stuff coming in through the waterline.
I found the screen exactly where he described. I didn’t need too, but I took the entire valve out, one hose clamp, an electrical plug, and the screw on fitting I described above. Simple, even for me. I took it all into the house, cleaned it out, washed it thoroughly and put it all back together. It’s working wonderfully again, just like it was designed to do.
A very simple fix to a very big problem. Didn’t spend a dime, even the telephone call was toll free.
The toilet has a built in macerator and is operated by a push button or a two push button electric wall mounted switch. The entire operation is electric, so when you push the button, it automatically adds more water to the bowl, then a valve opens allowing the contents into the macerator and then on to the holding tank. Then the bowl refills itself to a preset level, just like a toilet in your house. Apparently the nice part is that the toilet does not have to be located over the top of the holding tank.
Finally, I can’t say enough about the support from Thetford!
Oh, one last thing and in all caps…… TURN OFF THE WATER PUMP BEFORE YOU START.
