Bosch miniMAXX tankless instant hot water tank PROBLEMS!!

In my new house, I installed a Bosch tankless instant hot water tank. 13L, propane. It's not on the Bosch american site - I am in Mexico and this is where I bought it. I got propane put into my 300L tank the other day, and started testing everything. Stove lights perfectly. Next was the hot water tank. Clicks several times, not lighting. The first day, after three tries, the display says "EA". Tried it again today. Now it clicks each time I turn the tap on (and the pressure tank kicks in), but the display says nothing. Still no hot water. I don't know what to do. Please help!

you are soooo totally screwed....
. half the people in mexico dont even have hot water
so their is not going to be a service tech to help you

I suggest getting a tank type heater .....

Actually, a non-plumber helped me with this one, in the end. I only filled my propane tank 1/3. he suggested I fill it all the way, more pressure...Hmm...worked!
FYI) There is help in Mexico. There are plumbers. And most Mexicans I know DO have hot water - and I've lived in multiple places in Mexico. Don't assume

I dont assume anything, just takeing a good guess..

once the pressure goes down in that tank my guess is
its gonna be cold showers again..
