Water heater alternating hot and cold water

To the Good Folks of Cuenca,

I have an on-demand water heater, powered by propane. It is only 2-years new. At the beginning, it was producing hot water for a few minutes, then it turned completely cold for 20 seconds or so, then the water was hot again. The cycle repeated. I found there were pebbles/sand in the showerhead. Once it was cleaned out, the problem went away. Now the problem of alternating hot and cold water is happening again, and there is no obstruction in the showerhead. Any suggestion or recommendation is appreciated.
